Subsea 7 supports Centrica’s decommissioning program
UK’s Subsea 7 will provide decommissioning services for the second phase of Centrica’s Rose and Stamford gas field decommissioning program. The fields are located in the southern North Sea, offshore UK.
The project is the latest call-off contract under a partnership frame agreement signed in 2005. Subsea 7 has partnership frame agreements with several
independent operators, to provide services on a long-term preferred supplier basis.
“This collaborative approach is helping to drive down costs and promote early engagement on a wide range of projects,” Subsea 7 said in a statement on Monday.
Offshore activities are scheduled for 2016 and will be performed by one of Subsea 7’s six North Sea Diving Support Vessels (DSV). Engineering and project management will start immediately in Aberdeen.
Rose & Stamford
As for the fields to be decommissioned, Centrica operates both Rose and Stamford.
The Rose field located in the block 47/15, comprises a single subsea well (47/15b- 6W) tied back to the Perenco operated A2D platform via a 9.042km long, 10” nominal bore pipeline. First gas was achieved in 2004.
The Stamford Field lies in the UK sector (block 49/10c). The field was discovered in 1990 by Total Oil Marine, but was developed by Venture Production in 2008.
Ownership moved to Centrica in 2009 following the Venture Production acquisition. The field was developed by tying back a single Stamford appraisal/development well to the Markham platform located in the Dutch sector 7.5km from the Stamford well. The Stamford pipeline and umbilical crosses the median line into the Dutch sector.
