The Australian IMR Market

11

• Strong vessel coverage

• Diverse range of ROV providers

• Detailed Front End Engineering and Project Planning

• Significant investment in certain emergency response capabilities

– AMOSC Subsea First Response Toolkit– Emergency Pipeline Repair Packages

12

“What about unplanned events or unique unforeseenchallenges that require custom or innovative solutions?”

Let’s take a look at a few examples of unplanned challenges and some of the innovative solutions....

What is missing?

“A Pipeline Needing Repair” 2013

13

• Subsea pipeline identified as having a leak in Australia.

• Pipeline shut in costing operator lost production.

• Diverless Solution preferred.

• No readily available Pipeline Repair Tooling available locally.

• Urgent package required to prep the pipeline for repair.

• Urgent permanent repair clamp required in order to resume production.

“A Pipeline Needing Repair” 2013

14

• Diver installable repair clamp retrofitted to be ROV installable in 4 weeks.

• Pipeline coating required to be remove prior to pipeline repair.

• Protective Coating Removal Tool conception to readiness offshore required in less than 8 weeks.

• Small offshore project execution window available to complete project.

• Successfully executed on IMR support vessel.

“A Tree That Won’t Release” 2010

15

• Subsea Tree required to be removed for repairs.

• Tree unlock feature failed to operate by traditional unlock measures due to corrosion.

• Work over rig applied significant over pull on release rods with no success.

• Rig had to depart the field.

• An innovative approach was needed to release the tree without damage.

“A Tree That Won’t Release” 2010

16

• Field Shut in until solution could be provided.

• Tree Release Intervention Tool developed:

– 375 Tonnes Linear Pull– 88 Tonnes Inertial Mass

”Slide Hammer” feature– Short Timeline for design and

manufacture.– Successfully used from IMR

Support Vessel.

“Risers With a Bad Vibration” 2008

17

• TLP with Production Risers

• Risers equipped with VIV supression strakes & fairings during commissioning.

• Fairing’s fell off over the years of operation.

• Riser’s experienced Vortex Induced Vibration (VIV).

• Diverless solution required to install replacement VIV Suppression Strakes/Fairings

“Risers With a Bad Vibration” 2008

18

• ROV operable Strake and Fiaring Installation Tooling

• Successfully used to install hundreds of strakes and fairings.

• Mitigated the risk of fatigue on the riser.

“A Sheared Valve End Effector” 2013

19

● Multiple “stuck” ROV Operable Valves.

● Some valves with sheared Class 1-2 End Effectors.

● Marine Growth limited the valve from being operated.

● Stuck valve prevented Operator from producing well.

● Minimally invasive solution to remotely operate valve required.

“A Sheared Valve End Effector” 2013

20

● Bespoke Drilling Tool and standard torque tool with a custom “Spanner” EE developed

● Next best alternative was to pull the tree.

● Allowed Operator to start production.

● Conception to completion was 4 weeks.

“Pressure in the Annulus”

21

• High Pressure High Temperature Wells experiencing pressure build up within the Annulus around the production casing.

• Ability to remotely intervene and vent the pressure required.

• Requirement to maintain the integrity of the wellhead, monitor the pressure, and vent in the future was required.

“Pressure in the Annulus”

22

• Pressure Annulus Relief (PAR) Drilling solution developed.

• Drilled through casings in order to vent pressure.

• Monitored Drill Depth, Pressure, Speed.

• Installed plug with ability to vent pressure in the future.

23

“Do we (as an industry) underestimate the term IMR and what will be required to support the market ahead?”

The ability to quickly, efficiently, and safely respond to unplanned events will certainly increase and test the rapidly growing Australian subsea market.
