Field Andrew Area
Area Central North Sea
Operator BP
Development concept Subsea
Transport concept 28km pipeline to Andrew
Start-up Q1 2012
Comments: BP has issued the environmental statement for the Andrew Area development,
involving the subsea tieback of Kinnoull and further development of Andrew’s Lower
Cretaceous reservoir. Start-up on Kinnoull is scheduled for early 2012. There will be three
horizontal wells tied into a 150t, four-slot manifold. The wells will be drilled by semisub Byford
Dolphin starting in Q4. The manifold will be tied back to Andrew by a 28km, 14in production
pipeline in corrosion resistant alloy, plus a 6in lift-gas line and a 3in methanol line. The
pipelines may be bundled, in which case there will be four bundle sections. They will be routed
via the Arundel field where a two-slot manifold will be installed for future use. The lines will tie
into a 100t, gravity-base pipeline end manifold at the platform. A 44in caisson riser will be
installed on the jacket and a 750t reception module will be cantilevered on the topsides. The
following contracts have been placed: topside engineering services for modifications on
Andrew to Wood Group; subsea engineering services to JP Kenny; subsea trees to Cameron;
subsea controls to GE/Vetco; and subsea ball and gate valves to BEL. Tendering is also under
way for subsea construction, umbilicals, heavy-lift services, flotel support and module/caisson
fabrication. Conceptual engineering has been performed by Xodus.
Field
Athena
Area Central North Sea
Operator Ithaca
Development concept FPSO
Transport concept 2km in-field pipeline bundle
Start-up Mid 2011
Comments: The relaunched Athena project will have the BW Carmen FPSO as its production
facility; Ithaca issued a letter of intent to BW Offshore for it in Mar. The vessel will be
lengthened to include a submerged turret loading (STL) system. According to a new
environmental statement, there will be a single drilling centre connected to the FPSO by a
2km, 29in pipeline bundle containing an 8in production pipeline, 8in injection water line and 3in
service line. There will be four subsea production wells, of which three of which will be
recompleted appraisal wells, plus one water injector. They will be tied into a manifold
integrated into the bundle towhead. Drilling is due to start in Q4. Engineering support is being
provided by Petrex. Orders have been placed for long-lead items including subsea trees, which
are expected to be supplied by GE, and downhole electric submersible pumps (ESPs). Ithaca
intends to lease the subsea facilities. Reserves are 15.7m bbl, but the company is considering
adding two producers and a second water injector, which would double recovery.
