Prosafe SE is the world's leading owner/operator of semi-submersible accommodation vessels. The company is listed on the Oslo Stock Exchange.


Prosafe’s operations are related to maintenance and modification of installations on fields already in production, hook-up and commissioning of new fields, tie-backs to existing infrastructure and decommissioning.

Prosafe is listed on the Oslo Stock Exchange with ticker code PRS.

Accommodation/service rigs[edit]

Accommodation vessels offer additional accommodation, engineering, construction or storage capacity offshore. Prosafe’s vessels have accommodation capacity for 306-812 people. They have catering facilities, storage, workshops, offices, medical services, deck cranes and lifesaving and fire fighting equipment aboard. The vessels are positioned alongside the host installation and are connected by means of a telescopic gangway so that personnel can walk to work.


Prosafe was formed in 1997, when the platform drilling and technical services divisions de-merged from Transocean as a separate company and became listed on the Oslo Stock Exchange as Procon Offshore ASA. This company merged with Safe Offshore ASA, thereby entering the business segment of accommodation/service rigs, and changed its name to Prosafe ASA.

Prosafe acquired floating production company Nortrans Offshore in 2001, extending its activities to include the conversion, chartering and operation of FPSOs and FSOs.

In 2005, Prosafe sold the Drilling Services division. In 2006, the company acquired Consafe Offshore AB, which owned three semi-submersible accommodation/service rigs and one accommodation jack-up. This acquisition cemented Prosafe’s leading position in the market for semi-submersible accommodation/service rigs.

In May 2008, Prosafe spun off business division Floating Production. This business division became an independent company, named Prosafe Production Public Limited. On November 25, 2010, BW Offshore completed the 100% [2] acquisition of Prosafe Production Public Ltd., for approximately NOK3,120.92m ($489.88m).
