CAMELOT SUBSEA DECOMMISSIONING CAMELOT DECOMMISSIONING  Client: Helix UK  Period: 2012  Location: UK sector, Southern North \ Sea  Scope: − Disconnecting and recovery of Subsea infrastructure; Cutting and recovery of  Equipment: flow lines and mattresses − Protea (AIR Diving) − W-ROV services, Air Diving, use of cutting tool and grabber − WROV 14

TYPICAL SCOPE OF WORK  MANAGEMENT, ENGINEERING & WORK PREPARATION − MWS approvals − Risk- & environmental impact assessments − Workability assessments & motion analyses  PREPARATORY WORKS − Surveys & inspections \ − Installation of lifting eyes, structural steel and cutting  PREPARATORY WORKS (SUBSEA) − Subsea inspections − Removal and recovery of flowlines, spool pieces, jumpers, j-tubes, umbilicals and risers − Removal and recovery of concrete and frond -mattresses − Cutting, dredging, excavation and seabed rectification  HEAVY LIFT OPERATIONS & TRANSPORTATION  ONSHORE DISPOSAL (managing subcontractor) 20

LESSONS LEARNED OPERATIONAL COMMERCIAL  Drawings provided may not represent actual  Large execution window is beneficial situation (e.g. weights, marine growth, etc.) (Availability of assets vs execution window have an impact on price)  Unexpected situations to be dealt with (e.g.  Ownership of the offshore assets, possible scour holes, rock dumps or canvas mats used as JV’s protection).  Structural integrity / suitability lifting operations \  Liabilities, risk distribution and division of responsibilities to be clarified in early stage  Soil plugs / grout in piles  Variations and management of change  Drill cuttings and debris encountered (allow contractor time and freedom to deviate in  Make safe & inventory phase critical a controlled manner)  Purchasing & contracting strategy  (Crew) access more complex then expected (traditional approach or alliance)  Site access, simeops and 3 rd party interfaces  Division in Lots ? 22

DEVELOPMENTS 1. FLOATING JACKET REMOVAL • Based on buoyancy tanks • (As done for FRIGG in 2008) 2. COOPERATION \ • Based on complementary assets • (e.g. heavy lift vessel) 3. NEW ASSETS  Based on asset development 4. R&D / TML  Cutting technology / motion control 24
