Subsea 7, UK has been awarded a US$17 million contract from StatoilHydro for engineering and installation of the Snorre B Riser Replacement project in the Norwegian sector of the North Sea.
Snorre is an oil field in the Tampen area in the northern part of the North Sea on the Norwegian Continental shelf. The sea depth in the area is 300-350 metres. Snorre B is located in the northern part of the field and is a semi-submersible integrated drilling, processing and accommodation steel facility.
The scope of work involves engineering, subsea preparations and subsea disconnection and recovery of three off damaged flexible risers, the installation of three off new risers on the Snorre B platform and subsea tie-in of the risers to templates C and D.
The offshore operations are due to take place in three phases from April to September 2009. The main offshore operations, including riser recovery, installation and tie-in operations will be performed by Subsea 7's specialised flexible pipelay and construction vessel, the 'Seven Seas'.
In other news, Subsea 7 has won another major contract, worth US$200 million from Brazil's Petrobras.
This contract is for the Tambau Urugua and P-56 developments in the deepwater Santos and Campos Basins offshore Brazil. The Tambau Urugua scope of work is to engineer, install and commission two 12" (30.5cm) rigid steel 14.5-kilometre-long, client-supplied gas flowlines and associated subsea equipment.
The P-56 scope is to engineer, procure, install and commission two 12" (30.5cm) rigid steel 13-kilometrelong oil export pipelines, connecting the semi-submersible P-56 platform to the P-38 FPSO, and one 10" (25cm) rigid steel 8.6km gas export pipeline from the P-56 platform to the semi-submersible P-51 platform. The pipelines and pipeline end terminations will be supplied by Subsea 7.
The offshore pipeline installation project will take place in 2010 and will be carried out by one of Subsea 7's pipeline installation vessels.
The Tambau Urugua field is located in Santos Basin about 130km southeast off the Rio de Janeiro State coast, in water depths of 1,300 metres. The P-56 development is located in Campos Basin 320km east off the Rio de Janeiro State coast in water depths of 1,670 metres.
