Start-up imminent for Glen Lyon FPSO

BP is preparing the newbuild Glen Lyon FPSO for first oil at the Quad 204 project west of Shetland.

BP plans to start production at the redeveloped Schiehallion and Loyal fields by the middle of this year, with the 885-foot (270-metre) floating production, storage and offloading vessel Glen Lyon at the centre of the project.

The vessel replaces the Schiehallion FPSO and extends production at Quad 204 to 2035, or beyond.

KBR designed the 21,000-tonne topsides, which include production capacity for a projected 130,000 barrels per day of oil, 220 miilion cubid feet per day of gas and 380,000 bpd of produced water and seawater injection.

Other topsides facilities and modules include accommodations for 140 people, power generation and emergency power, oil processing train, two gas processing trains, produced water treatment and injection, flare gas recovery and chemical injection facilities.

SBM Offshore supplied the vessel’s 100-metre tall, 12,000-tonne turret, said to be among the largest built to date.

The control room has a fibre optic link to shore, whereas crews on the original FPSO had to rely on a much slower satellite communications system, BP says.

The vessel also incorporates some new crew safety features, such as light fixtures within easy reach so that bulbs may be replaced without ladders or the need to obtain permits to work at heights.

The Glen Lyon hull and topsides were assembled at Hyundai Heavy Industries’ yard in South Korea.

BP says the Schiehallion and Loyal fields have produced about 400 million barrels of oil since production started in 1998.

The operator and its Quad 204 partners, Shell and OMV, say the complex contains a remaining estimated 450 million barrels.
