Bergesen d.y. ASA, one of the largest shipping companies in the world, has chosen UK engineering company Peter Brotherhood Ltd to supply two steam turbine driven alternator sets for a floating production, storage and offloading (FPSO) vessel for Woodside’s Chinguetti field off the coast of Mauritania. The two 24 MW condensing steam turbine driven alternator sets designed and manufactured by the company will be the largest steam turbines for a FPSO vessel.
Each set will consist of a turbine, gearbox and alternator, all mounted on a common bedplate which incorporates the oil system. The turbines will accept steam from gas fired boilers on the vessel and will exhaust to a separate condenser.
The two steam turbine driven alternator sets will be tested on steam at Peter Brotherhood’s manufacturing facility and will be delivered to Singapore for installation on the top deck of the FPSO vessel in February 2005. Engineers from Peter Brotherhood will be employed to commission the machines on board the vessel.
Bergesen d.y. ASA chose Peter Brotherhood because of the company’s extensive experience in manufacturing steam turbine driven alternator sets for installation on FPSO vessels. These sets have to incorporate features to enable them to operate reliably in a floating environment, where they can be affected by, for example, the pitch and roll of a ship.
Peter Brotherhood’s managing director, Stephen Fitzpatrick, said: ‘This is the second contract we have secured from Bergesen in recent months. Winning this order has strengthened the company’s position as a world-class supplier of steam turbines for FPSO vessels worldwide. The combination of Peter Brotherhood technologies and FPSO experience provide an exclusive and superior solution for our customers.’
