TUGBOAT DESIGNS AND DELIVERIES ABOUND

Recently delivered to Suderman & Young Towing Company in Houston, Texas, the Eva is the first in a series of three Robert Allan Ltd.-designed RApport 2600 tugboats the company ordered from Master Boat Builders Inc. in Coden, Ala. The main propulsion power for the Eva is delivered by a pair of Caterpillar 3512E, EPA Tier 4 certified diesel engines, each rated at 2,213 bhp at 1,600 rpm, and driving a Schottel SRP 430FP Z-drive unit to give the vessel a free-running speed, ahead of 12.5 knots and a bollard pull ahead of 52.5 tonnes.

The electrical plant consists of two

identical John Deere 4045AFM85 diesel gensets, each with a power output of 99 ekW 480V, 3-Phase, 60 Hz.

Ship-handling fenders at the bow consist of one tier of 36- OD by 18-inch ID cylindrical fender at the main deck level; a 20- by 18-inch W-fender below the cylindrical fender and along the sheer lines of the main deck; and 18- OD by 9-inch ID cylindrical fendering at the stern.

“We are proud to have delivered the first of a series of three tugs for Suderman and Young,” said Rice. “They have been a great partner and we look forward to the deliveries of the Eva’s sister ships later this year.”

“We are very excited to welcome Eva , our first of three RApport 2600s into the fleet,” said Kirk Jackson, president, Suderman & Young Towing Company. “This newest tug along with the others soon to be delivered will enhance and build upon our ability to provide excellent towing service to our customers. We appreciate our professional mariners and other team members that are an integral part of providing this outstanding customer service experience. Master Boat Builders is great to work with and they have delivered a beautiful, well-constructed tug. We look forward to future deliveries.”

Master Boat Builders Inc. also booked a contract to build a new tugboat in addition to the three-boat series for Suderman & Young last summer.

“We at Master Boat Builders take pride in our work and are heartened by this vote of confidence from the team at Suderman & Young,” said Garrett Rice, president of Master Boat Builders. “Suderman & Young is one of the premiere tugboat operators in the United States and we are excited to continue partnering with them to provide another quality tugboat to serve the western Gulf Coast ports.”

The tugboat will have an overall length of 98 feet, 6 inches, beam of 42 feet, 5 inches, and produce a bollard pull of over 80 metric tonnes. The vessel will feature two Caterpillar main engines (3516E), EPA Tier 4 certified and each producing 3.500 hp, along with two Schottel Z-Drive thrusters (SRP 510FP), and a Markey Machinery Company bow winch (DEPSF-48-100).

And in November, Master Boat Builders executed a contract to build two new tugboats for New Canaan, Conn.-headquartered Moran Towing Corporation. The two tugs will be the first that Master Boat Builders will build for Moran Towing, which traces its roots backs to 1850 and whose coast-to-coast operations today include vessel towing, bulk marine transportation, LNG support operations, and environmental recovery services.

“We look forward to working with Master Boat on this project,” said Sean Perreault, vice president, engineering services at Moran Towing. “Master Boat has a great reputation for delivering quality equipment on a consistent basis and we hope this new contract will lead to future opportunities for collaboration between the two companies. While we have an ongoing commitment to our traditional suppliers, our demand from customers has given us the opportunity to work with new partners that we hope will become long term relationships.”

Naval architect and marine engineering firm Crowley Engineering Services, which has a long history of designing vessels for Moran, created the design for the new tugboats which will meet United States Coast Guard Subchapter-M regulations and will be ABS classed.

The new tugboats will have an overall length of 86 feet, a beam of 36 feet and produce a bollard pull of over 55 tonnes. The vessels will each feature twin Caterpillar 3512E main engines, EPA Tier 4 certified and each producing 2,549 hp, Kongsberg US 205S FP thrusters and a Markey Machinery Company DEPC-48 bow winch.

“Moran is one of the most respected tugboat operators in the U.S. and we are honored they have chosen us to build their next set of tugs,” said Rice.
