Forties FB

Forties Bravo (FB) is a fixed steel jacket platform in the Forties oilfield, installed in June-1975. It originally hosted drilling and limited processing but now exports production fluids directly to Forties Charlie for central processing. It produces oil and associated gas, functioning as a satellite linked by subsea flowlines.

Field

The Forties field produces from Paleocene sandstones with significant oil and associated gas volumes. FB forms part of a network of fixed installations (FA, FB, FC, FD, FE) developed in the 1970s and 1980s to exploit these reservoirs. FB's fluids feed central processing hubs rather than being fully processed onsite.

Facilities

Forties Bravo's jacket supports production wells but has reduced onboard processing capacity compared with Alpha and Charlie. Wells feed manifolds that route multiphase fluids via a 14" subsea production pipeline to Charlie. FB's utilities are limited: it imports power from the Forties power network rather than generating locally, and supports chemical injection for hydrate and corrosion control, basic control systems, and instrumentation linked to central control. Safety features include emergency shutdown, fire/gas detection, and remote isolation valves. Produced fluids are processed at Charlie, which handles separation, dehydration, compression and export. FB's design reflects a satellite role with minimal topside processing, enhancing the field's overall flow architecture by feeding into centralized processing and export trains.
