Subsea 7 completes pipeline bundle for Buzzard

Subsea 7 has installed a 5 km pipeline bundle for the CNOOC International Buzzard Phase II (BPII) project, ready to link the new northern area wells back to the existing platform.

Bundle technology provides all subsea production, water injection and gas lift flowlines, as well as control functions and end manifolds in a single integrated system, which is fully fabricated and tested onshore. The BPII Bundle system also incorporates a large drill centre manifold (36m long and weighing 300 tonnes), allowing for up to 12 wells to be tied in.

Fabricated and launched from Subsea 7’s Wester fabrication site near Wick, Scotland, the complete 5,500 tonne system was towed 150 km to the Buzzard field using a specialised mid-depth tow method.
