A MESSAGE FROM THE ADCI PRESIDENT ■ BILL CROWLEY

THIS EDITION IS DEDICATED TO

gear, all the gear we use, have used or will use. Diving Equipment and the never ending desire to improve the current state of the art is a constant cycle of advancement. An idea or need, plus innovation and application, are the keys to solving problems and making a new product.

Think about the gadgets you use every day and compare them with the gadgets of 20 years ago. Cell phones were bulkier and heavy, certainly not as cleaver and compact as the “smart phones” we use now. Automobiles, planes, satellite television, HD and 3D TV, the list is really endless. When was the last time you used a film type camera? Change happens.

These early years of the 21st century have created a new culture of safety in our industry, and with those changes operational procedures and behavior are modified to meet the challenges. The equipment of this era and procedures of conduct (personal and professional) will change the way we operate now and in the future; each day is supposed to be a little better than the last. Remember, safety on the job is primary; we are all supposed to go home after work.

The 6th edition of the ADCI Consensus review period has ended, and, as I write this, the comments we received are being reviewed. In general, the comments were good, pointed out some serious editing issues and provided input on some of the tougher issues. A different point of view can be very helpful. Thank you to all that participated in the review process.

I don’t want give my age away, but when I first became a commercial diver the equipment of choice for most of the entry level shallow harbor and inland divers in the North East USA was a “Jack Brown” shallow water band mask. (I still like those masks, purchased a new one in the last year or two, works great in the pool.) There were, of course, numerous options of helmets, mostly made of metal, and slowly the emergence and acceptance of fiberglass band masks and helmets. I remember using a homemade blue modified football helmet (an air hat made by a GOM diver of some notoriety in the 1960’s), held tightly on your head by a braided polypropylene jocking strap (3/8" line) from the back to the front of the helmet via between the legs. Experience dictated it had to be carefully positioned and it worked very well in shallow water construction. Some senior free lance divers used heavy gear; it is all they trusted. There were other choices, but they were somewhat limited, unlike today. I could think of a dozen hats I would like to own but that is another story.

Remember to always question whether your safety procedures meet the task at hand.

Be safe and always do the right thing.

A MESSAGE FROM THE EXECUTIVE DIRECTOR â– PHIL NEWSUM

I HOPE YOU WILL ENJOY and find this issue of Underwater magazine informative, as it spotlights new products, new trends and techniques for the offshore and inland sectors, as well as essential safety gear. Remember, the magazine is continually looking for articles to compliment the focus of each issue. Please refer to the 2011 Editorial Planner, which can be found at www.underwatermagazine.com.

Additionally, I want to thank everyone who participated and attended Underwater Intervention 2011.

A special thanks to both the Kevin Hardy and Steve Struble for their tireless work in coordinating the Technical Program, as well as Bill Crowley, Drew Michel and Rebecca Roberts of the Show Committee.

The standard practice of selling out the show’s floor space can squarely be attributed to the hard work of Rebecca Roberts. Her efforts are a big reason why, globally, Underwater Intervention continues to be the largest show of its kind.

ADCI Consensus Standards 6th ed. Update Sincere thanks to all of you that took the time to submit your comments during the Consensus Standards 90 Day Review Period. These comments were very helpful toward providing direction to the Consensus Standards Review Committee on further revisions required to the draft. The approach that was taken involved the Committee reviewing all comments submitted from 25 September to 12 December, during the course of several days of meetings. All comments submitted from 13 December to 25 December were then addressed at a subsequent series of meetings. Despite the fact that additional sets of comments were submitted after the deadline and outside of the electronic format designated, they were still very welcomed by the committee. The philosophy of the committee has always been to not exclude any comment(s), as they may contain that one piece of information which could add to the overall value of the document.

The Association is committed to continually review the Consensus Standards to ensure they reflect current best industry safe practices. It is truly an evergreen document. The Consensus Standards also reflect offshore and inland diving from an international perspective. It is not a Gulf of Mexico or North Sea document that solely focuses on offshore operational, manning or equipment requirements.

Presentations will be given during the course of the year to outline the comments that were submitted and the further revisions that were made, based on those comments.

In Closing Unfortunately, 2011 got off to a rather regretful beginning with the fatality of two divers. Initial reports indicate that both fatalities involved the divers removing their helmet and mask. It would be inappropriate to speculate on the details surrounding these initial reports, while investigations of both incidents are still ongoing. With that said, it would be appropriate to reinforce the safe practice of only removing the helmet or mask once they are topside or at another designated safe location. Communication and confirmation between the diver and topside personnel is essential.

The ADCI sends it condolences to the friends and loved ones of both divers.

Helmets without Headaches The newest diving helmets offer many advantages, including increased durability and comfort CERTIFIED COMMERCIAL DIVERS ARE

a lot like football players, motorcyclists, construction workers and racecar drivers in at least one respect: They all need a good helmet for protection. These days, commercial divers have a wider variety of helmets to choose from than ever before. Here are a few of the latest offerings from companies with a history of producing quality helmets.

Kirby Morgan’s KM-37SS helmet

16

UnderWater

MARCH/APRIL 2011

Kirby Morgan Dive Systems International Inc. At first glance, Kirby Morgan’s list of diving helmets reads kind of like the roster of a football team, with the numbers 17, 27, 37, 47, 57 and 77 all representing different models and giving certified commercial divers a variety of helmets to choose from. Among divers seeking an especially rugged helmet, the Kirby Morgan 37 SS helmet has proven to be popular.

The 37 SS features an entirely stainless-steel shell as well as a stainless side block, helmet ring, bent tube, handle and other key components. It also features a quick-change communications module, available with either bare wire posts or a waterproof connector, and allows for easy, efficient maintenance of the helmet’s communications equipment.

The advantages of the stainless-steel helmet include: • Rugged helmet shell and other components • No refinishing required if the surface is scratched or gouged • Elimination of threaded inserts for securing port retainer to helmet shell The 37 SS is built for comfort, with a head cushion that gives the helmet a secure, wellbalanced feel as well as excellent thermal protection during long work periods. The internal adjustable chin strap, along with the adjustable neck pad on the locking collar, gives the diver a comfortable, secure fit. And the helmet-attached yoke system has an adjustable neck pad made from a scuff-resistant elastomer. In conjunction with the spring-activated front neck dam ring lock, it provides protection for the bottom of the helmet.

Connie Morgan, the owner of Santa Maria, Calif.-based Kirby Morgan, said the company’s

long history of producing quality helmets and diving equipment allows divers to feel comfortable with their purchase.

“The Kirby Morgan 37 SS is a nice helmet, t,” she said.

“Our product line has been proven over time. e. The U.S. Navy, U.S. Army and militaries around the globe lobe use our helmets. We’re consistent. We’ve been here since nce 1965, so we can back up our product.”

The 37 SS also features bubble-deflecting “whisker whisker wings,” which keep bubbles farther from the face port and ears, improving visibility and decreasing internal noise.

It also has a “Positive-Lock” latching system, tem, first developed

by Kirby Morgan in 1992, consisting of two sealed pull pins that are pulled forward to release the neck collar and neck dam locking system. Even when the latches are released, ed, the O-ring-sealed neck dam maintains a positive seal and will not ot allow the seal to be broken until the collar clears the diver’s shoulders, ders thus helping to prevent flooding of the helmet.

DESCO Corp.

DESCO Corp., founded in 1937 under the name Diving Equipment and Salvage Co., was among the four firms that produced the bulk of the U.S. Navy’s diving equipment during World War II. DESCO made more than 3,000 Mark V and Navy helium helmets during the war, and more than half a century later, those models are still among the 14 varieties of helmets produced by the Milwaukeebased company.

DESCO owner Ric Koellner said the DESCO Air Hat is especially popular among certified commercial divers, who use it for tasks such as contaminated water and nuclear wastewater work. Koellner said one of the helmet’s most attractive attributes is its durability.

“Since it’s a free-flow air hat with a double exhaust, it’s really the hat of choice for contaminated water, including nuclear,” he said.

“It’s copper- and brass-constructed, so in essence, I could drop it off the top of a four-story building and fix it for about a third of the cost of a replacement hat. If you did that with a fiberglass hat, you might as well just buy a new hat for $6,000 or $6,500.”

The DESCO Air Hat is used in all types of contaminated environments, including sewage treatment facilities, nuclear power stations, oil tanks, chemical facilities, disaster-recovery work, foodprocessing plants and paper mills.

The Air Hat’s brass castings are deep-soldered to a 1/16-inchthick spun copper shell. It can be disassembled and reassembled

Desco Air Hat

using only a screwdriver and a wrench, and it can easily be put on and removed by the diver without assistance from the tender. Using the adjustable exhaust valve, the Air Hat can be adjusted to either side of neutral buoyancy underwater with ease. With its low center of gravity and balance, it rests comfortably on the diver’s head. The interior headliner is adjustable for size, and the foam pads are covered in leather for comfort.

Among the standard features on the Air Hat, which sells for $4,980, are: • Double air inlet valve with non-returns (bail-out non-return machined for SCUBA whip) • Adjustable double exhaust valve • Stainless-steel air-control valve rated at 6,000 psig • Two video/light blocks • Communications housing fitted with two binding posts, with a communication plug connection option • Two-wire communications transceiver • Tin-plated finish • Brass parts have high-polish finish • Size 15 neck dam is standard (other sizes can be substituted by request) • Adjustable safety jock strap Also standard is a double air inlet elbow equipped with two non-return valves. The lower inlet is for the surface air supply line, while the upper bail-out non-return is machined to accept a SCUBA whip. The upper inlet is supplied with a dust cap to protect the threads and prevent dirt entry while not in use. www.adc-int.org ■ www.underwatermagazine.com

Composite Beat Engel Beat Engel, the owner of Biel-Bienne, Switzerland-based Composite Beat Engel, pronounces his first name as if it were two words, “be at,” but when it comes to his DSL B-2 helmet, he feels that his product simply can’t be “beat.”

Unlike many free-flow air hats, which subject the diver to about 100 decibels of noise, the DSL B-2 reduces the noise inside the helmet to somewhere between 65 and 82 decibels, according to the most recent round of tests performed by the company.

“With some of the other helmets, divers can eventually go deaf,” Engel said. “Guys are working with those helmets for several hours, and it’s louder than at a rock concert.”

One of the DSL B-2’s best features is that it’s easy to find replacement parts. Engel said his company can ship parts worldwide, but the metric screws and other key parts can be found at most hardware stores and dive shops.

“There are many people who don’t want to be dependent on the manufacturer after they buy the hat,” Engel said. “With this hat, there is no dependence on the manufacturer. The DSL B-2 is our most versatile helmet. With this model, you can do everything. You can have it as a free-flow hat or as a demand-valve hat. It’s the same shell, and all you need is a kit for whatever purpose you want.”

UnderWater

MARCH/APRIL 2011

Engel’s DSL series of helmets are made of hand-laminated fiberglass and are built in a modular fashion, ranging from a demand valve for simple underwater work to a quiet free-flow helmet for contaminated environments. The helmets also provide a field of vision that is up to 40 percent greater than other commonly used helmets.

“Strong front and side covers protect the entire air distribution system and vent the exhaled bubbles to the back,” Engel said. “There is a full compatibility for mounting lamps and cameras on top of the helmet as well as the possibility of mounting an underwater welding lens. The flexible handles on the bail-out valve, free-flow/defog valve and adjustable demand valve are shock-absorbent and provide the best protection from harsh environments.”

The DSL B-2 sells for between $5,500 and $9,300. Its features include: • Neutral buoyant • Ergonomic shape, adaptable for different head sizes and forms • Optimized angle of vision • Solid, round O-ring-sealed neck ring with horizontal-clamping levers and safety locking system

Gorski

• Optimal protection of entire air distribution system; exhaled air guided to the backside • Most parts are standard and obtainable anywhere, allowing for inexpensive and easy maintenance • Increased wearing comfort • Compatible with commonly used communication systems and diving suits

When Les Gorski sought to invent a durable helmet that could be used for a wide range of diving jobs, one of the first ideas he came up with was to put all of the helmet’s main components inside the shell. His GS2000SS stainless-steel helmet, which sells for $6,395, has no exterior components that can be damaged, so maintenance is simple and inexpensive.

“The things that divers like most about this helmet are the simplicity and the ease of maintenance,” said Gorski, who runs his company out of Houston. “It’s extremely simple, and that’s really important because it’s life-support equipment. It has to be functional, but it has to be simple.”

The G2000SS’s all-metal design makes adapting it to auxiliary equipment such as lights or a helmet-mounted camera easy. The front port window is made from the strongest machineable Lexan material for increased safety. The mounting holes in the port are individually drilled through, allowing the retaining bolts to pass through the window itself, reducing the risk of the window popping out in the event of a hydrogen explosion during underwater cutting operations.

Gorski designed a unique retaining system to lock the neck dam in place. The second-stage demand was designed for higher input pressure to eliminate any dial breath necessity, achieving balance

helmets and ease of breathing. The Poseidon Cyclone 5000 has been proven to work for depths up to 1,800 feet when used by U.S. Navy EDU at the simulated test dive in 1979, in addition to being used as a workhorse scuba regulator around the world for decades. Gorski incorporated this regulator to fit within the helmet, where it is fully protected at the lower front portion of the nose area, an integral part of the shell configuration.

The helmet does not require a side block, which was replaced with a free-flow/exhaust valve in-line with the second-stage regulator. The back-mounted manifold contains the internal screen used to strain any debris, the auxiliary port and two check valve assemblies, one for the main supply and the other for the reserve backup air or gas supply. This configuration allows for the high-pressure stainless-steel tubing between the back manifold and second-stage regulators to be kept inside the helmet.

Some of the Gorski G2000SS helmet’s features include: • Designed using SolidWorks 3D software • Investment casting used for casting parts • All castings done using 316L-grade stainless steel • Drag finish for best surface protection from saltwater • All castings stress-relieved to eliminate cracks • All machining programmed and done in CNC • Poseidon Cyclone 5000 second stage for the helmet regulator • Total helmet weight: 29 pounds

BOWTECH PRODUCTS LTD Riser Inspection System for BP Schiehallion

Bowtech Products Ltd worked in partnership with IMES Group to produce a riser inspection system which was successfully used to view and record riser installation activities on the BP Schiehallion FPSO (Floating, Production, Storage and Offloading system).

The mechanical aspects of the design involved the system frame and the hydraulic rotating and positioning components used on the tool.

Mounted on the frame are three pan, tilt & zoom, colour, explosion proof video cameras to enable viewing of the riser replacement from different angles. All three cameras are controlled from a top-side electronic control suite on deck using the custom-designed Bowtech Products Ltd Controller.

There are also seven explosion proof LED lamps mounted in clusters on the frame of the tool, the brightness of each cluster of lights is controlled using the Bowtech controller.

Bowtech engineering experts were responsible for the top side electronic control suite, cameras, lights, cabling etc. and provided on-site support during the installation and operation of the system.

spotlight CORTLAND Cortland introduces new laying-up and armouring capabilities which provide very long length ROV umbilicals that are smaller and lighter, with higher operating temperatures and greater working loads. These armoured umbilical designs, through reduced copper content, minimized core and umbilical diameters, and lighter weight steel armour, are perfect for existing and ultra-deep-water applications. Cortland’s tailored umbilical designs also generally allow for smaller winch packages, which translates into savings with overall project cost, and precious deck space.

DCL ENGINEERED SOLUTIONS Houston-based DCL Engineered Solutions introduces their new line of “Workhorse” thimbles for highperformance HMPE synthetic ropes. The thimbles’ 3:1 D/d ratio design accommodates grommet configurations and has been tested to exceed the Minimum Break Load of the strongest Dyneema ropes.

Detachable ears allow the thimble to be inserted into existing eyes; and the channel depth provides 100% protection of the rope eye. U.S. distribution is provided by DCL Mooring & Rigging and Southwest Ocean Services.

Replacing the roulette thimble/shackle connection for MODU synthetic mooring ropes, DCL Engineered Solutions has developed their “Workhorse” SRC connector.

The connector allows continuous spooling of multiple rope sections onto the storage reel without damaging the rope. It takes the side-load over the stern, inserts into existing eyes, provides 100% protection of the rope eye and can be independently stopped-off. All of which saves time and costs in connection/disconnection during rig moves.

spotlight iROBOT CORP. EXTENSIVE DATA COLLECTION AT GREATLY REDUCED COSTS iRobot Seaglider Makes a Difference Collecting data for less costs The iRobot 1KA Seaglider gathers data for a fraction of the costs of traditional manned research vessels and moored instruments. Seagliders can be operated for several hundred dollars a day versus traditional methods that cost 10’s of thousands of dollars a day. It can be deployed around the world, navigated to any area of interest and piloted by any web enabled device, while gathering and reporting data in near real-time. Advanced design and engineering enables long duration data gathering missions of up to 10 months at sea that cover thousands of nautical miles.

Sustaining autonomous long-term missions The Seaglider achieves continuous, uninterrupted and autonomous missions for as long as 10 months at a time. Seaglider achieves minimum power consumption and maximum efficiency by propelling itself by effecting buoyancy to provide thrust for descent and ascent through the ocean. A small shift in buoyancy coupled with a small shift of the vehicle’s centre of gravity and a stable, low-drag, hydrodynamic shape enables the Seaglider to effortlessly dive and glide while activating sensors at pilot designated intervals to collect data.

Efficient Shallow and Deep Water Operation The Seaglider operates efficiently from littoral zones to open ocean, able to dive and collect data in waters as shallow as 15 m and to depths up to 1000 m. No alteration of the glider is required to enable this dual operation or to collect a continuous stream of data from one environment to other. This breakthrough enables researchers to study shallow water and deep water during the same deployment, allowing scientist to study areas like the drop off across the continental shelf and the phenomena that occur at this transition.

The Gen 5 Stinger has taken more than two years of development, testing and additional refinement upon previous models, and it shows in its sustainable, highvolume performance. Improvements and refinements include reliable locking head functionality and dramatic contactor bolt life (reports from the field related bolt life of 3 days with under continuous use).

Every detail of Gen 5 Stinger was reevaluated in the redesign process. The center of gravity of the Gen 5’s oval head was placed near the top for incredible balance, comfort and performance. The domed top of the head and the raised center of gravity places the head in the hand in the proper position to be threaded on the handle, EVERY time, the first time. Light and maneuverable, the Gen 5 weighs in at a just 3 lbs., which includes the ultra-flexible whip. The balance of the Gen 5 makes it a superior tool, a natural extension of the hand. Other improvements include the tactile pointers which make it possible for a diver to easily identify the orientation of the head. The Gen 5 was also designed to freely guide the rod in to a serious set of robust clamping jaws that provide an incredibly positive bite on the rod, with each load. The Gen 5 Stinger is incredibly robust and is not just intended for use underwater. Actually, the Gen 5 is as happy out of the water as in, since the new Gen 5 enjoys painstaking design improvements that greatly reduce or eliminate overheating.

FIBERGLASS JACKET SYSTEMS FOR PILE RESTORATION

Figure 1: A completed Fiberglass Jacket Restoration.

SUMMARY: THIS PAPER DISCUSSES SYSTEMS and techniques that have been utilized to restore the structural integrity and protect concrete, steel, and wood piles for more than 35 years. Many bridges in active use today are well beyond their intended designed life.

Since it would be much too costly and time consuming to replace these bridges with new bridges, proven repair and rehabilitation systems are critical to the life and safety of these structures. This paper will discuss the use of a fiberglass jacket system that utilizes epoxy and cement based grouts specifically designed for bridge pile restoration.

INTRODUCTION Since the inception of bridge design, owners, engineers, architects and contractors have been utilizing materials, methods and systems to rehabilitate and protect these same structures. Every bridge has a designed life. This life cycle may vary depending on many factors, such as type of building material (wood, steel, concrete); climate; environment; live load and dead load; wetting and drying cycles; chloride intrusion, etc. For many years deteriorated bridge piles, wood, concrete and steel, were repaired or replaced using the same materials from which they were originally constructed. The biggest drawback for this type of repair and rehabilitation is that these elements are subjected to the same forces that caused the original deterioration.

It is just a matter of time before repairs will have to be made again and again, creating a constant maintenance cycle for the life of the structure. As cost of materials and labor continue to rise, these types of repair methods may actually cost more than the original cost of the structure. It was therefore necessary to create a repair system that would be effective on concrete, wood or steel pilings, prevent future deterioration and be maintenance free. This repair system would provide an economical, long-term solution to this age old problem.

The basic premise for this system incorporates a pre-molded fiberglass jacket specifically designed for the pile to be repaired. This jacket may be round, square, rectangular, H shaped or a series of flat or curved pieces to be connected to cover a large structure.

The jacket will be sized to create an annular void of ½" or larger, to be filled with epoxy grout or a combination of epoxy grout and a special underwater cement based grout, based on the type of pile and the extent of the section loss.

The initial development of this type of system had to address many elements, such as: • The system would have to be user friendly. No matter how effective the system was, if contractors and divers could not easily install the system, there would be great reluctance to use it.

• The system would have to be equally effective on concrete, steel and wood piles.

• The system would have to be effective above and below the waterline. The jacket and filler materials must be able to be placed underwater if necessary.

• The system must employ sections that can be easily connected for long pile length repairs where necessary.

• The system would have to be placed without dewatering of the annular void between the existing pile and the fiberglass jacket. The filler materials must displace the water out of the jacket.

• Placement of the system should not interfere with the activity of the structure. The bridge does not have to be shut down to install the system.

• The system must be effective in salt water, fresh water and brackish water.

• The system must be able to be modified in the field to fit around bracing, piping, hangers, etc.

• The epoxy grout must bond tenaciously to the wood, concrete or steel piles as well as the fiberglass jacket. The epoxy must be pourable or pumpable and must fill all voids without the use of external or internal vibration.

• The components of the system must be environmentally safe to marine life.

• The system must stop all corrosion and deterioration in the area it is applied to.

• The system must be maintenance free.

EARLY TESTING BY STATE ROADS COMMISION In order to achieve all of these elements a great deal of testing was done in the early 1970s to evaluate the merits of a fiberglass jacket pile repair system. Extensive testing was performed on the fiberglass jackets, as well as the epoxy and cement based grouts.

jackets In 1969, The Maryland State Roads Commission laboratory performed tests on the fiberglass jacket system to determine the effective bond between the fiberglass jacket and the epoxy grout. After extensive testing, it was concluded that the epoxy grout bonded tenaciously to the fiberglass jacket even when poured into a void containing salt water. After placement, the epoxy grout was allowed to cure for seven days.

The technicians then tried to remove the fiberglass jacket from the test pile section.

The technicians had to destroy the jacket in order to remove a section because the epoxy grout had bonded so tenaciously to the jacket and the pile. A 3" core was taken using a diamond core drill through the epoxy and the concrete pile section. The epoxy grout exhibited full bond to the pile, thus producing a monolithic structural system.

EARLY PROJECTS UTILIZING THE FIBERGLASS JACKET SYSTEM CONCRETE PILES: NORFOLK, VA One of the first projects to utilize the fiberglass jacket and epoxy system was the 26th Street Bridge in Norfolk, VA. The original plans called for placing a square shaped jacket around the deteriorated square piles and filling the void with the moisture insensitive epoxy grout. However, soon after the job began, it was discovered that the section loss of the concrete piles was much greater than anticipated. This would greatly increase the amount of epoxy grout that would be required to fill these larger voids. The more epoxy, the more expensive the job would be. The city of Norfolk, VA worked with the company that developed 42 UnderWater 501135_Sea.indd 1

the fiberglass jacket system to find an economical solution to this problem. The area had an abundance of river gravel. Testing was done to see how the epoxy grout would react when mixed with the river gravel. Test cubes were made and it was determined that the epoxy mixed with the river gravel would far exceed the minimum requirements of the design strength for the epoxy grout. The river gravel increased the yield of the epoxy to the extent that the project was able to come in on time and on budget.

DIVERS SUPPLY, INC.

CONCRETE PILES: ANNAPOLIS, MD In the early 1980s the fiberglass jacket system was utilized to repair and protect over 300 Raymond Hollow Piles on the Chesapeake Bay Bridge in Maryland. The piles measured 54" diameter. The piles were exhibiting deterioration in the form of cracks that would allow moisture and salt to penetrate the piles. The structure was located in a region that sees temperature ranges from 0°F to 100°F. If left untreated this could cause structural damage to the piles that would eventually endanger the structure.

Based on testing conducted by the Maryland State Roads Commission in the 1970’s, and successful use of the fiberglass system on other structures, a contract was let to place the system on more than 300 piles. The jackets were placed in the splash zone where the wetting and drying cycles and freeze thaw cycles were concentrated.

The jackets were 55" in diameter x 1/8" thick x 8' long. The ½" annular void was filled with the moisture insensitive epoxy grout without dewatering. The jackets were inspected 20 years later and were still performing like the day they were placed.

In the late 1970s, following the implementation of the Clean Water Act of 1972, it was determined that as the harbor waters were cleaned up, they became a breeding ground for marine borers, which are a great threat to timber piles supporting bridges and piers. The marine borers would burrow their way deep into the wood piles to the point that the piles would become structurally unsound. Again testing was performed on timber pile sections to determine the effectiveness of the jacket system. The epoxy grout easily penetrated the bore holes and tunnels and filled them while filling the annular void between the jackets and the piles. Over the past 30 years thousands of wood piles have been repaired utilizing the fiberglass jacket system.

ently from concrete or wood. Corrosion of the steel, the most common type of deterioration, may be caused by wetting and drying cycles, chemical attack, and exposure to the atmosphere.

Steel H piles may be repaired in several ways. Fiberglass jackets can be fabricated in the shape of the H pile. This type of jacket will be made in two pieces to facilitate ease of placement around the H pile. The standard void between the steel H pile and the H shaped fiberglass jacket will be ¾" minimum due to variances during the fabrication of steel H piles resulting in final dimensions that are not always exact. This void is filled with the moisture insensitive epoxy grout.

Another method of repairing steel H piles with fiberglass jackets is to place a round fiberglass jacket around the steel H pile and fill the void with epoxy grout 6" in the bottom and 4" in the top, leaving the majority of the void to be filled with a more economical specially formulated cement based grout that can be pumped or poured into the void without dewatering. By encapsulating the special cement grout with epoxy the cement grout is protected from moisture and air.

Figure 6: Ketchikan, AK – a Trident Seafood processing facility sits on a timber pile structure. Severe deterioration of the piling was threatening the facility. Restoration was completed with the fiberglass jacket system without needing a plant shutdown.

SPECIFYING THE RIGHT SYSTEM Since there are many different repair scenarios it is important to choose the right repair system for each project.

Some important factors in choosing the type of fiberglass jacket and repair grouts are: • Type, shape and length of pile repair.

• The number of piles to be treated.

• Location of the piles. (Are they easily accessible; are they close to each other; how much head and working room there is; are they completely underwater or partially underwater; is there any obstructions like cross bracing, piping or hangers etc; can they be accessed from the pier, work barges or platforms.)

jackets • Amount of work performed by divers, amount of work performed by others above water.

Considering some or all of these factors will help the engineer, owner and contractor make an informed decision on the best fiberglass jacket system to be utilized on a given project.

The two most common types of pile repairs using fiberglass jackets are:

1. Section loss of 25% or less. This type of repair utilizes a ½" annular void between the fiberglass jacket and the pile. This void is filled completely with the moisture insensitive epoxy grout.

2. Section loss of greater than 25%.

This type of repair utilizes a 2" or greater annular void between the fiberglass jacket and pile. The bottom 6" of this void is filled with

CONCLUSION Since 1970 thousands of concrete, wood and steel piles have been successfully repaired and restored to their original structural integrity or beyond. The fiberglass jacket system of pile repair has proven to be an effective, economical and long range repair system.

Over the past 30 plus years there are many marine contractors that have a long and successful track record of fiberglass jacket installations all over the world.

The fiberglass jacket pile repair systems are constantly being innovated and improved, to enhance their durability, ease of application, and economy. With all of the testing that has been performed on these systems and the many successful projects that have been completed around the world, the fiberglass jacket pile repair system has proven that it is a viable and economical solution to a massive problem of bridge pile deterioration that exists today and will exist far into the future.

Ratios equal to or greater than 100% restore original allowable capacity, ratios less than 100% do not restore original capacity.

ADCINews&Notes En el encuentro además se trataron temas sobre prevención y Medicina Hiperbárica.

Una de las conclusiones del Tercer Simposio Nacional de Buceo

Hacia unnuevo marcoregulatorio para la actividad LA CREACIÓN DE UNA MESA de trabajo que permita

Medicina Hiperbárica

reunir información relativa al buceo y a sus regulaciones fue el corolario del Tercer Simposio Nacional de Buceo realizado en el país.

Diana Valderrama, Gerente de Prosub y organizadora de este encuentro, indica que estos simposios nacieron como una manera de apoyar a la actividad, difundir la normativa vigente y entregar información en torno a la medicina y a la prevención, temas que fueron centrales en esta tercera versión, realizada en el centro de eventos SurActivo, en Hualpén.

Uno de los puntos más importantes para este sector es la importancia de establecer una discusión sobre la legislación que los regula. “El problema que nosotros tenemos es que el reglamento iguala a todos los buzos. Reúne a los mariscadores, quienes viven de la extracción de los productos del mar y su venta, y a los profesionales y comerciales que prestan servicios a empresas que tienen infraestructura bajo el agua y que requieren de mantenimiento, como muelles, puertos, barcos, centrales hidroeléctricas y empresas sanitarias”, apunta la gerente.

Agrega que son dos rubros totalmente diferentes, por lo que es preciso que exista un nuevo marco regulatorio que diferencie ambas actividades y que establezca la creación de entidades educacionales especializadas, destinadas a darles una formación básica.

“El desafío más importante que ya nos hemos impuesto es hacer una mesa regional para conversar y evaluar dónde es posible mejorar la actividad y que no nos impongan -como ocurre hoycambios en los reglamentos”, precisa.

Uno de los temas centrales de este simposio fue la Medicina Hiperbárica, que fue abordada por el médico Andrés Llarena Astudillo, capitán de fragata, oficial médico, especialista en anestesia y medicina hiperbárica, quien también participó en el rescate de los 33 mineros de la Mina San José.

El profesional explica que esta disciplina engloba a la medicina de buceo, la de submarinos y la de cámaras hiperbáricas que hoy se utilizan en la oxígenoterapia, una terapia de complemento para aquellas patologías donde los tratamientos estándar no dan los resultados esperados. Ésta mejora los procesos de cicatrización y ayuda a la reparación de fracturas o tejidos.

Andrés Llarena señala que la primera función de la Medicina de Buceo es la prevención, a través de la selección de quienes desean dedicarse a esta actividad. Expone que para ello deben fijarse protocolos de verificación de condiciones de salud y de capacidades, que varían según la actividad: desde las menos estrictas, que corresponden a las recreacionales, y las más rigurosas para las operaciones militares. Posteriormente está la supervisión médica de la actividad y, en tercer lugar, la medicina de imprevistos.

Llarena acota que en Chile hay sólo 4 ó 5 especialistas en Medicina Hiperbárica, porque no existen escuelas que los preparen. “Actualmente, para obtener esta especialiadad hay que viajar a Europa o a Estados Unidos. Una de nuestras ideas es conformar un grupo de especialistas lo suficientemente sólido, trabajando incluso con Argentina, de modo que tengamos, eventualmente, una facultad común y un área de posgrado para formar especialistas en Medicina Hiperbárica”, concluye. www.adc-int.org ■ www.underwatermagazine.com
