PETERBOROUGH, UK -- Fred. Olsen Production ASA has chosen Peter Brotherhood to supply two condensing steam turbine driven generator sets for the Knock Allan FPSO vessel for the Olowi field offshore Gabon.
Each of the two 27 MW sets consists of a turbine, gearbox, and generator, all mounted on a common bedplate that incorporates the oil system. The turbines will accept steam from gas fired boilers on the vessel and will exhaust to a separate condenser also supplied by Peter Brotherhood. The turbines are the world's most powerful to be installed on an FPSO vessel, according to Peter Brotherhood.
The two generator sets recently were tested on steam at Peter Brotherhood's manufacturing facility and will be delivered to Dubai Drydocks for installation on the top deck of the vessel. Peter Brotherhood will commission the machines on board the vessel.
The vessel is being converted from a trading tanker to an FPSO at Dubai Drydocks. Once operational, it will be able to store 1 MMbbl and produce 22,000 b/d of oil.
