MAN Diesel & Turbo offers new offshore drilling generator set

Offshore staff

COPENHAGEN, Denmark – MAN Diesel & Turbo has launched its PA6 B Offshore GenSet that specifically targets semisubmersible drilling rigs.

The PA6 B is a four-stroke, medium-speed engine built at MAN Diesel & Turbo’s St. Nazaire, France, facility. St. Nazaire will assemble individual PA6 B OG units together with an alternator in constructing the new, offshore GenSets. Typically, 8 × 16PA6 B OG units are installed aboard a semisubmersible both for main and emergency power supply.

In developing the new OG-variant, the original PA6 B engine has been adapted to meet market demands. One innovation is on emissions, with the result that the PA6 B OG is Tier II-compliant and can also meet Tier III regulations with the SCR (Selective Catalytic Reduction) technique. Another key development is that the PA6 B OG now employs SaCoSone, the company’s engine-safety-and-control system, while the range of turbochargers suitable for operation with the new engine has accordingly been updated.

Its power range from 4,440 to 7,400 kW makes it suitable for diesel-electric propulsion and power generation in the offshore segment. The PA6 B engine is resistant to shock and the offshore GenSet can deal with tilts of up to 25° in any direction. Its ability to handle transient load increases and long-term, low-load operation are also noteworthy, while its proven design and OEM components facilitate long maintenance intervals, the company said.
