Peter Brotherhood has despatched what is believed to be the world's most powerful steam turbine driven alternator sets for a floating production, storage and offloading (FPSO) facility.

Peter Brotherhood has despatched what is believed to be the world's most powerful steam turbine driven alternator sets for a floating production, storage and offloading (FPSO) facility.

The Peterborough, UK-based, company produced the two condensing steam turbine driven alternator sets for Single Bouy Moorings, which operates the world's largest fleet of FPSOs.

Peter Brotherhood won the GBP 3.7 million contract because of its extensive experience in supplying steam turbines for FPSOs and its ability to deliver the equipment quickly.

This can save fleet operators substantial sums of money.

The two turbo-alternator sets built by Peter Brotherhood each produce 12MW of power.

This is believed to be 50% more than any other in operation on an FPSO in the world.

The turbo-alternator sets will be transported by road to Felixstowe where they will be shipped to Singapore for installation on board the FPSO Marlim Sul which operates in the Marlim Sul field off the coast of Brazil.

"Our ability to produce these turbo-alternator sets quickly was a key factor in winning this order", said Stephen Fitzpatrick, Managing Director of Peter Brotherhood.

"They have now both been despatched - precisely to schedule.

Our ability to offer fast, on time delivery is very attractive to FPSO operators.

This, along with our expertise in this market, is why we win such prestigious contracts as this".

Peter Brotherhood has extensive experience in manufacturing steam turbine alternator sets for installation on FPSOs.

These turbo alternator sets have to incorporate special 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.

The geographic location in which turbo alternator sets will be installed and the harshness of sea conditions that could be encountered are factors which need to be considered during design.

Schiedam-based IHC Gusto Engineering, which is a sister company of Single Buoy Moorings, has provided design, engineering and consultancy services for many FPSO projects including the Marlim Sul FPSO.

The steam turbines were purchased by SBM Marly and were designed and manufactured to meet the requirements of the American Bureau of Shipping.

Each steam turbine, gearbox and oil system was tested on steam at Peter Brotherhood's manufacturing facility prior to despatch.

Engineers from the company will commission the machines on board the vessel.

The company has been designing and manufacturing steam turbine driven alternator sets for FPSOs since 1981 when it supplied two turbines to one of the world's first FPSO vessels, the Shell Medora, which was moored in the Fulmar Field in the North Sea.

The company now has steam turbines installed on a number of FPSOs moored off the coasts of Africa as well as Indonesia, Thailand, Australia and in the North Sea.
