Status of Greenhead Base, Lerwick, Shetland Background Experience Future Presented by James Johnson Decommissioning Manager for PetersonSBS
Background - Decommissioning Interest began in 1999 � Market Development � Established in 1999 to market and develop Decommissioning opportunity for Shetland � Contract award in 2005 from Aker Solutions and Total for the Frigg Cessation Project � Currently working on FEED and feasibility studies for Topsides, Jackets, Subsea and Single Lift � Operational Philosophy to build on Best Industry practice to develop Shetland into a “centre of excellence” for Decommissioning
Background - Company Stakeholders � Shetland Decommissioning � The trading name for a joint venture / cooperation agreement between PetersonSBS [PSBS] and Veolia Environmental Services [Veolia] with support from Lerwick Port Authority [LPA] � Stakeholders Today � PetersonSBS Develop & Operate the Facility Providing Marine & Quayside Services (formerly SBS Logistics) � Veolia provide the Scrap Handling, Waste Management & Environmental Services � Lerwick Port Authority Operate the Harbour
Background - Geography
Background - Lerwick Harbour • All Weather Port • Open 24/7 • Over 3,000m of Quayside • Excellent Freight Links with the UK Mainland • Local Support Services with 30 years of Oil & Greenhead Base Gas Experience Decommissioning Facility Drill Cuttings Plant Fabrication Facility New Landfill Site Energy Recovery Incinerator
Background - Decommissioning Facility � Decommissioning Facility � Concrete Pad with impermeable membrane - covering an area of ~20,000 sq. m. • Includes Wash Bay, Bunded Storage, Quarantine Area & Emergency Stations � The Pad is Fully Enclosed - all drainage leads to Class 1 Interceptor • Fully Licensed with PPC permit issued by SEPA • RSA authorisation approved for receipt, handling and temp storage of LSA/NORM
Experience - Piece Small � Piece Small Operations � Piece Small Decommissioning of platform MCP-01 started in 2006 � The 1 st Campaign ran from Aug-Dec 2006 � This was completed in 2008 with the 2 nd Campaign running through Jan-Dec 2008 � The Greenhead Base acted as the forwarding supply for all of MCP-01 Logistics requirements and all piece-small Waste materials were processed through Greenhead
Experience - Piece Small � Piece Small Operations � Primary processing carried out offshore; � Materials were packed into skips and delivered onshore via PSV � Scrap Handling, Waste Segregation, Processing and Environmental Accounting managed Onshore • This included all Hazardous Wastes; e.g: Asbestos, WEEE, Batteries etc • All materials were packaged and shipped to Licensed and Approved Disposal routes
Experience - Single Piece - TCP2 - MSF (~11,100 Te across the Quay) (one of the largest structures loaded into the UK) � TCP2 Module support Frame ~ 8730Te � The MSF was lifted offshore by Saipem UK using the S7000 Crane Vessel � Landed onto a bespoke Grillage on the S600 Launch Barge it was towed to shore in July 2007 � Many months of Preparatory Engineering & Construction works were required Onshore � Also the presence of the skid rails on the barge required the MSF to be loaded-in over the Bow of the barge, this required significant barge works and barge manoeuvring
Experience – MSF - Barge Manoeuvring - Video
Experience - Single Piece - TCP2 - MSF � Load-in Logistics and Planning � Load-in Operations were all planned to specific date and tide; � 358 axle lines mobilised from Europe, America and Asia � Tailored Ballasting & Mooring systems Mobilised & Installed � 3 Weeks of tightly programmed Preparations & Fabrications Onshore and On Barge (All works completed on schedule and without significant incident)
Experience – MSF - Load-in Operations - Video (~11,100 Te across the Quay) (one of the largest structures loaded into the UK)
Experience - Single Piece - TCP2 - MSF � Handover for Decontamination � Decontamination Operations took approximately 12 weeks � Access (7m height), Safety Inspections, Make Safe (Install Emergency Equipment, Emergency Exits, Lights, First Aid and Fire etc) � Inventory & Mapping � Decontamination - Draining & Cleaning � Asbestos Removal � W.E.E.E Removal (Waste Electrical and Electronic Equipment Regulations)
Experience - Single Piece - TCP2 - MSF � Demolition Methods � Reduction by Machine was maximised - Leibherr 984 + 19Te LaBounty shear � However Hot-work & Pre-cutting was required due to extreme steel thickness (Up to 100mm) � Exclusion zones set-up for the Cutting Operations � Positive Pressure masks for Hot-work (Minimise risks from Iso-cyanate paint fumes)
Experience - Single Piece - TCP2 - MSF � Summary and Conclusion � The TCP2 MSF is one of the largest “single piece” structures to be transported and decommissioned from the North Sea to date � The success of this project has proven Shetland’s capability for handling Large Scale projects � The Onshore Operations were completed on schedule, and without significant incident or LTI � We are now looking to the future for further works, alliances and development opportunities
