• According to some major operators, about 80 % of the lifting incidents are related to lifting operations in the drilling area
Where does it end if the newtrend is not stopped?
???
PTIL/PSA
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 safetyinitiatives grow!
I wish youa good conference!

Why?????
Be aware and do not get caught by surprise!
The battle for safe lifting?
Don’t get caught by routine!
Fort Eben Emael, Belgium 1939Eben 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 barracksfor 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!
Integrity is not about your strength but about knowingyour weak links!
Be aware and do not get caught by routine!
Know your weak spots!
Lifting operations are like good sex;
It should never be a routine!

The snubbing risks were identified but:
Low probability, severe consequence scenariosshould have triggered more mitigation andcontrols (including Emergency Response).
Snubbing operations on a live well were treatedas routine operations.

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
Lack of inherentlysafe design measures
Lack of technical protective measures
Lack of information toexposed persons
Accidents and
incidents
“Swiss cheese” model
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
Other issues
PTIL/PSA
One challenge – non-harmonizedstandard: 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/PSAWorkshop Brussels 22 March 2011
PTIL/PSA
The needs for standards from a regulatory authority’s point of view
• To set the level of safety in standards• To allow for a goal setting approach• To cover developments in technology• To provide predictability for enforcement from
regulators and for industry• To encourage safety by compliance on a
voluntary basis and to incorporate best practices

PTIL/PSA
The way forward sofare in CEN
• The Machinery Working Group of the EU Commission has given CEN TC 147/WG 21 “Non-fixed 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 C-standard for elevators
Start with EN ISO 13155 (Harmonised C‐standard for similar products)
Use existing ANSI/API 8C/ISO 13535‐2002 for identification of basic global requirements for such products
Identify requirements that possibly could had prevented recent incidents and accidents
Apply the MD ESHRs through EN ISO 12100‐1 and ‐2 (A standard on machine safety) and identify requirements for elevators by risk assessment
1)
2)
3)
4)
Amend EN ISO 13155 to adress elevators with requirements from 2) , 3) and 4), including hazard list and verification methods
5)
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

HPS weight and dimensions
►Host Protection Structure (HPS)• Dry weight incl. rigging and water filled top frame = 210.0 [Te]• Submerged weight: 140.0 [Te]• LxBxH = 31.2x31.2x9.5 [m]

Installation vessel Skandi Arctic
► Skandi Arctic – main dimensions• Length over all: 156.9 [m]• Length BP: 137.7 [m]• Breadth: 27.0 [m]
7
Challenges due to HPS footprint
Crane capacity and lifting heightSea fastening arrangement
Deck handling during overboarding
8
Crane capacity and lifting height
►Crane capacity• Minimum required radius for overboarding: 24.0 [m]• Static weight of HPS close to the crane capacity
9
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

11
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
12
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)
13
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?
14
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
15
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
16
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

Lesson learnt
26
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
35
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
36
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
37
Summing up
38
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

“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.”
26.04.2011 12
BHSU - Project main purpose
Develop a system which remove personnel from exposed areas during critical Bulk Hose Handling operations.
26.04.2011 13
BHSU - Project main design criteria BHSU - An automated Bulk Hose
Securing System• To remove personnel from exposed area
during Bulk Hose Handling.• Easy to retrofit on existing fleet• No adaption are required on rig side or
existing bulk hoses.• Handle various types and dimensions of
