Intro
Alwyn North B is a steel jacket drilling and production platform on the Alwyn North field in the UK sector of the northern North Sea. Installed as part of the Alwyn North field development in the mid-1980s, it performs drilling and production functions with associated export interfaces to field infrastructure.
Field
The Alwyn North field lies ~160-km east of the Shetland Islands, discovered in 1975 and producing since 1987. The reservoir comprises Jurassic sandstone oil and gas, developed with bridge-linked platforms and subsea templates.
Facilities
Alwyn North B’s steel jacket supports drilling modules and production well slots tied into the field’s subsea templates. Crude and associated gas are routed via flowlines to the Alwyn Central processing platform (Alwyn A) and onward into export pipelines serving UK Continental Shelf and beyond. Facilities include separation units, produced water handling, basic gas conditioning, and connection points for export pipelines. Power generation, safety systems (flare, emergency shutdown), and integrated control systems support long-term operation. The platform also integrates well-intervention infrastructure and communications with central processing.
