According to some major operators, about 80 % of the lifting incidents are related to lifting operations in the drilling area 26/04/2011 PTIL/PSA 3

One (very) recent incident to illustrate the new trend • A slip joint was in the process of being lowered from vertical to horizontal position at the catwalk.

• The bails were forced 45 degrees against the elevator link blocks which broke, hence the bails were forced further out of the lifting lugs of the elevator.

• The slip joint (weighing 23 tonns) fell approx. 4 meters.

• The slip joint first hit the load rest. The riser spider, before falling to the drill floor, fell against the drillers cabin before stopping.

PTIL/PSA

Center latch elevator incident consequences • The load rest to the left of the slip joint was hit and jumping directly towards the signaller (flagman/lift leader) before it hit the tongue post, changed direction and stopped • Actual consequences were material damages only • Potential consequence could have been a fatality PTIL/PSA

What is common to the drilling lifting incidents?

• Poor identification of operational hazards • Poor design, i.e. the special drilling lifting gear is not inherently safe and needs to be improved to meet modern safety standards • Difficult or impossible to verify correct locking • User information poor or not present • The lifting tools are not identified as lifting equipment and treated as such (planning, inspection, certification, maintenance) • Poor planning management and supervision • Some of the special drilling lifting gear have been designed and manufactured in accordance with API 8C, now EN ISO 13535

PTIL/PSA

The industry challenge…

• All elevators should be made inherently safe by design • Harmonized standards should be developed for all drilling lifting tools based on the principles of EN ISO 12100 1&2 o The work of CEN TC 147 WG 21 for updating of EN 13155 to include manual and mechanically operated elevators is very promising

• Remote controlled elevators (mechanical) should be used for lifting of all sizes of conductors

PTIL/PSA

The industry challenge …

• All special lifting equipment (hoisting tools) in the drilling area must be identified • The operator and drilling contractor must establish a safe system of work and make sure the drilling hoisting tools satisfy regulatory requirements for lifting equipment • A systematic review and risk analysis should be carried out for all special drilling lifting equipment • The special lifting equipment should be modified or changed out according to the results from the analysis PTIL/PSA

Let the good safety initiatives grow!

I wish you a good conference!

Why?????

The battle for safe lifting?

Be aware and do not get caught by surprise!

Don’t get caught by routine!

Fort Eben Emael, Belgium 1939 Eben Emael was a giant fortress.

17 bunkers from various types. Total firepower: 2100 kg. a minute. An impressive piece of Belgium defense. Inside this fortress, 60 meter under the top, underground barracks for 1.200 soldiers. Military experts from various countries agreed that this fortress was one of the strongest in Europe.

To concur this fortress was impossible!

The fall Underpunkter

• Guess how much time the Germans needed to get control of the fortress? • Answer: 15 minutes and a crew of 71!

The fortress strength was its weakness!

To convinced of their own strength (laid-back).

Design based on WO I. No studies or analyzes on new threads.

Artillerists not trained for man to man battle.

The bottom line was that the fortress failed on organization, technology and human skills.

The fortress was NOT sound!

Know your weak spots!

Integrity is not about your strength but about knowing your weak links!

Be aware and do not get caught by routine!

Lifting operations are like good sex; It should never be a routine!

Risk = probability x consequences

The snubbing risks were identified but: Low probability, severe consequence scenarios should have triggered more mitigation and controls (including Emergency Response).

Snubbing operations on a live well were treated as routine operations.

Maintenance

Competence

Focus on your primary process!

16th North Sea Offshore Cranes and Lifting Conference

LTI as indicator for safety on the installation?

Ask for backlog on preventive maintenance and the amount of curative work orders!

The best contribution to real safety is to perform your job perfect!

Your equipment in perfect condition, perfect level of competence an planning.

Resulting in a perfect (Safe) execution.

What is common to the drilling lifting incidents?

• Poor identification of operational hazards • Poor design where the drilling lifting gear were not inherently safe and needed to be improved to meet modern safety standards • Most of the drilling lifting gear have been designed and manufactured in accordance with API 8C, now EN ISO 13535

PTIL/PSA

Safe design of machinery EN ISO 12100 part 1&2 (safe design of machinery) Lack of general principles for safe design are root causes for accidents and incidents Lack of information to exposed persons

“Swiss cheese” model

Lack of inherently safe design measures Accidents and incidents

Lack of technical protective measures Other issues PTIL/PSA

One challenge – non-harmonized standard: EN ISO 13535 • As a result of the shortcomings of ISO 13535 (former API 8C) and the findings during our past and current investigation, PSA has launched an international market surveillance program on manually operated elevators made according to EN ISO 13535 • This program is supported by DEA in Denmark, HSE in the UK and SMM in the Netherlands

PTIL/PSA

DNV study for PSA • Det Norske Veritas AS (DNV) has been requested by PSA to perform an evaluation of the locking mechanism on some manually operated side door elevators.

• DNV concluded that the locking mechanisms with “safety pin” did not give sufficient risk reduction effect compared to inherently safe design measures.

Hence, the elevators do not fulfil the principles of safety integration given in Annex I part 1.1.2 in the Machinery Directive 98/37/EC.

PTIL/PSA 11

The way forward sofare in CEN • The Machinery Working Group of the EU Commission has given CEN TC 147/WG 21 “Nonfixed load lifting attachments” a mandate to establish a harmonized standard for elevators • Such requirements could be incorporated into EN 13155:2003/A1:2005, Cranes - Non-fixed load lifting attachments, last cited in OJ C 336 (2005-12-31).

PTIL/PSA

Possible strategy to develop a Cstandard for elevators 1)

Start with EN ISO 13155 (Harmonised C‐standard for similar products)

2)

Use existing ANSI/API 8C/ISO 13535‐2002 for identification of basic global requirements for such products

3)

Identify requirements that possibly could had prevented recent incidents and accidents

4) 5)

Apply the MD ESHRs through EN ISO 12100‐1 and ‐2 (A standard on machine safety) and identify requirements for elevators by risk assessment Amend EN ISO 13155 to adress elevators with requirements from 2) , 3) and 4), including hazard list and verification methods PTIL/PSA

If harmonised standards like EN ISO 12100 part 1&2 are not followed, the risk of damage to personell, fatalities or major accidents and are higher

PTIL/PSA

Safer products = less risk The key to safe drilling hoisting tools

Presumption of comformity

Compliance with EHSRs

Challenges due to HPS footprint Crane capacity and lifting height Sea fastening arrangement Deck handling during overboarding

7

Crane capacity and lifting height ► Crane capacity

• Minimum required radius for overboarding: 24.0 [m] • Static weight of HPS close to the crane capacity

8

Crane capacity and lifting height ► Rigging design

• 10Te crane block must be landed on deck • Lifting height at R = 24.0m did not allow slings long enough to connect rigging besides HPS • Solution: remove minimum 2 off hatches and lower hook/slings through roof of HPS • Final decision to remove 4 off hatches for increasing weather criterion to Hs,ops = 2.0m • Dry weight of structure (water filled): 180.0 Te

Sea fastening arrangement ► Design of outriggers

• Outriggers extending 8.5m outside vessel port side • Designed to withstand impact with waves over entire length during transit • Lifting height further reduced due to height of outriggers/grillage

11

Deck handling during overboarding ► Use of crane tugger winches

• Primary tool for controlling the overboarding • Not possible to utilize from lift-off position due to: - HPS top frame located too close to crane pedestal - sheaves being fixed (no swivel)

12

Deck handling during overboarding ► Use of crane tugger winches

• Structure should be square to crane boom for crane tuggers to be effective • Safe distance between HPS top frame and crane pedestal • Plan for lifting the structure into this position in a controlled manner?

13

Deck handling during overboarding ► Use of crane tugger winches

• Solution: use of 4.0m high bumpers to rotate the structure around one leg • Lift HPS 3.0m off deck, rotate/boom out to R = 24.0m • Take up slack in crane tuggers before lifting HPS to 5.0m off deck and out of bumpers

14

Deck handling during overboarding ► Bumpers for rotation of HPS

• Height of bumpers: 4.0m • Marking applied at 3.0m as visual reference for crane driver during rotation/boom out • Bumpers located in the middle between overtrawlable fins/mudmat supports

15

Deck handling during overboarding ► Use of tagging towers

• 3 off tagging towers included as contingency for overboarding • T1 used to initiate rotation of structure, and as hold-back until crane tuggers tensioned • For the remaining part of the overboarding, T1-T3 used only to follow the load

Connection of rigging to crane block •

Crane block lowered through roof of the structure with 1 off crane tugger attached

• Crane block lowered through roof of the

structure with 1 off crane tugger attached

• Crane tugger reconnected to HPS top frame by use of man riding basket

27

Overboarding step 1 • Lift HPS to 3.0m above deck • T1: take up slack

28

Overboarding step 2 • Rotate HPS around aft STBD leg/boom out to R = 24.0m • T1: follow the load • Take up slack in crane tuggers

29

Overboarding step 3 • Lift HPS to 5.0m above deck and out of bumpers • Adjust orientation of HPS with crane tuggers

30

Overboarding step 4 • Slew the crane at constant radius • Start taking up slack with T2 once leg is clear of the crane pedestal

31

Overboarding step 5 • Slew the crane at constant radius • Follow the load with T1 and T2

• Slacken off T1 before wire interferring with the crane pedestal • Follow the load with T2 and T3

32

Overboarding step 6 • Structure 90° to vessel side in position for lowering through the splash zone

33

Lowering through splash zone • Crane tuggers kept tensioned until structure in the water

• Crane tuggers slackened off

34

Lessons learned from simulator exercises • Familiarising crane driver/deck foreman with the project -> feedback • Optimize position for winches and tagging towers on deck • Visualisation useful for detection of clash/snag points • Video presentation for information and briefing purposes

35

In addition: Test lift during mobilisation ► Test lift with all wires connected

• Familiarisation of crane driver and deck crew • Final check to ensure no clash/snag points • Good to use video for discussion and briefing/familiarisation of crew

36

Summing up

37

Summary ► Training and familiarisation

• • • • •

Simulation is real time and reasonable realistic, Simulation is valuable tool for understanding and planning the job Simulator training is a first approach for familiarisation On board Test lift is important for familiarisation of deck crew Simulator Visualization/video is of great value for briefing personnel onboard

Conclusions and limitations

1. Why simplified formulae for crane tip motions are needed?

Offshore lifting operation • Highly weather dependent Wind, wave, current...

• Vessel dependent Size, shape, COG, crane configuration...

• Lifting object dependent Size, shape, weight, position...

• Expensive Nok 300.000/day ex. fuel, equipments and project personnel for a typical installation vessel in North Sea.

Zero injuries – an overall objective!

1. Why simplified formulae for crane tip motions are needed?

Hydrodynamic analysis • To define an acceptable weather window for the selected installation vessel • To widen the range of suitable installation vessel for the selected operation season • To provide load information for the lifting object design

Zero injuries – an overall objective!

1. Why simplified formulae for crane tip motions are needed?

BULK HOSE SECURING UNIT “Statoil contributes to improve safety in bulk operations offshore “  Statoil and Evotec formed in November 2009 a partnership through Statoil`s LOOP program. Statoil contributed financially in the development of Evomec` safety concept, "Bulk Hose Securing Unit" (BHSU).  The prototype is now installed and tested on the Eidesvik vessel "Viking Queen", and has been used in bulk operations since 1 December 2010.  Feedback from the personnel involved is positive. Use of BHSU both simplifies and improves the working conditions for crane operators and deck personnel in the handling of bulk hoses.

“Evomec`s BHSU‐system improves the safety during bulk operations offshore.”
