Holeby 7 March 2006. MAN B&W Diesel has settled a GenSet re-powering contract with the Brazilian oil drilling operator QGP (Queiroz Galvão Perfurações S. A., Rio de Janeiro). The company’s Semi Submersible Drilling Vessel, ‘Atlantic Star’, will be subject to a major refurbishment task, which includes the replacement of the electrical power plants’ original diesel generators. The new power source will be based on four MAN B&W Diesel type 7L27/38 Holeby Generating Sets.

The GenSet engines, which are scheduled to be supplied from Denmark during April 2006, will be delivered with common base frames matched for the American, National Oilwell Baylor, alternators. The total engine output from the four GenSets is specified to 9 240 kW (4 x 2 310 kW), corresponding to an electrical output of 8 780 kWe. A decisive parameter for the specification and final selection of the new power source was due to the favourable load response characteristics from the medium-speed L27/38 GenSets.

The consulting design company for the project is Projemar SA, Brazil, and the extensive refurbishment job is to be carried out by Maua Jurong S/A. After completion, the estimated geographical operational area for the ‘Atlantic Star’ is the waters off the Brazilian Atlantic coast.
