Quality Management

• SIRIUS is the main tool for integrating sustainability in our business practices

• SIRIUS is compliant with ISO 9001 and OHSAS 18001 and maintains ISO 14001, ISPS

and ISM certification where applicable

• We continously monitor, evaluate and improve the SIRIUS application and its content

...is essentially about securing that we deliver what our customers want

•We have a process for revision of the management system, which enables internal andexternal stakeholders to provide feedback, either via the SIRIUS revision form,

management reviews, customer surveys, or stakeholder meetings

• The feedback is integrated into one Sustainability plan (HSSE, CSR and Quality), which

guide our efforts in delivering what our customers want

We have a systematic audit framework in place to secure

that we, as well as stakeholders, comply with our values

and sustainability policies



Constant Care”intet tab skal os ramme, som ved rettidig omhu kunne afværges”

”My old saying ’No loss should hit us

which can be avoided with constantcare’ this must be a watchwordthroughout the entire organisation”

A. P. Møller in a letter to Mærsk Mc-Kinney Møller, December 2nd 1946



Rig Moves

Wet TowDry Tow (Heavy-lift)

Our units are moved by dedicated and specially trained

Towmasters who are in overall charge of the rig move.

This ensures safe and efficient rig moves.



Extracts from NWEA Guidelines• 3. Tow Masters

• Actively participated in the execution of at least five rig move

operations on a similar MOU type or a suitable combination of rig

moves and simulator training. (This should be documented.)

• Extensive knowledge of all relevant Rules and Regulations.

Now: ”GOMO”

• NWEA Guidelines For The Safe Management of Offshore Supply and

Rig Moving Operations.

• Extensive knowledge of the Rig move plan.

• English language capabilities Participated in the execution of, at least

three rig move operations onboard an anchor handling vessel, or

previous experience as AHTS Master or relevant marine experience.



Replacing NWEA. Presently (2012) sent out by IMCA for comments

GOMO: GUIDELINES for OFFSHORE MARINE OPERATIONS

7.4.3.6 Tow Master(s)

Tow masters must be able to demonstrate sufficient expertise in relevant MOU

move operations and appropriate levels of actual experience.

In this context the tow master should have participated in MOU movingoperations in the following operations in the following capacities:

In relation to semi-submersible units acted as a stand-alone Barge

Supervisor on such units for a minimum of three (3) rig moves under

supervision, or in a position of responsibility as a rig move observer

for a minimum of five (5) rig moves.

In relation to self-elevating units….. same as above!

7.4.3.6 Tow Master(s)

In addition, the tow master should:Hold valid STCW Class 1(Deck) or equivalent qualification.

Hold valid GMDSS Certificates.

Have full understanding of the proposed operation, including

Punch Through!!!



Punch Through!!!

The Noble David Tinsley experienced “Punch Through"while conducting Preloading Operations on May 8 2009

All three Legs have penetrated the Sea Floor off the Coastof Qatar, causing severe damage to the Jack-Up and legs



Punch Through!!!

Vantage Drilling Rig, Sapphire Driller experiences a Bow Leg Run

/ Punch Through in the early morning hours on 30 Oct 2009

”It appears a Zero Air Gap Preload was being conducted, which

most likely minimized Potential Structure Failure”



MAERSK VICTORY”Punch Through” 1997 – Adelaide, Australia



Risk of Rapid Penetrations!

•Rig at positive draft to Zero air gap• (Positive draft requires higher preload to achieve the required Seabed Reaction)

• Preload as close as possible to sea level

- Gain buoyancy in case of rapid penetrations

- Pending actual weather, sea state and tide

• re oa one eg a a me

- To reduce the overall weight of the rig andthen minimise potential structural damage

• Closely monitor the Penetration versus Seabed Reaction

as weight is added

• To catch the first indication of which Penetration Curvethe spud can is following: Lower or Upper Bound or ?



Preloading – Moving Boundaries!

“Punch Through?”“Punch Through?”

”Controlled Rapid Penetration”



Departure – Freeing Legs

• Leg and Spud Can are stuck in the soil due to

vacuum underneath the Spud Can combined

with soil on top of the Spud Can.

• Jetting below the Spud Can will break down the

vacuum and start filling up the gap generated

by the leg creeping upwards.

• The hull buoyancy will overcome the weight of

soil on top of the Spud Can.
