Presented by James Johnson Decommissioning Manager for PetersonSBS
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
The trading name for a joint venture / cooperation agreement between PetersonSBS [PSBS]
PetersonSBS Develop & Operate the Facility Providing Marine & Quayside Services
Veolia provide the Scrap Handling, Waste Management & Environmental Services Lerwick Port Authority Operate the Harbour
Drill Cuttings Plant New Landfill Site Decommissioning Facility Energy Recovery Incinerator Fabrication Facility
Concrete Pad with impermeable membrane - covering an area of ~20,000 sq. m.
The Pad is Fully Enclosed - all drainage leads to Class 1 Interceptor
Piece Small Decommissioning of platform MCP-01 started in 2006 The 1st Campaign ran from Aug-Dec 2006 This was completed in 2008 with the 2nd Campaign running through Jan-Dec 2008 The Greenhead Base acted as the forwarding supply for all of MCP-01 Logistics requirements and
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
(~11,100 Te across the Quay) (one of the largest structures loaded into the UK)
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
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
(~11,100 Te across the Quay) (one of the largest structures loaded into the UK)
Decontamination Operations took approximately 12 weeks Access (7m height), Safety Inspections, Make Safe
Inventory & Mapping Decontamination - Draining & Cleaning Asbestos Removal W.E.E.E Removal (Waste Electrical and Electronic Equipment Regulations)
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)
The TCP2 MSF is one of the largest “single piece” structures to be transported and
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
