[citation needed] Prosafe is listed on the Oslo Stock Exchange with ticker code PRS.

The vessels are positioned alongside the host installation and are connected by means of a telescopic gangway so that personnel can walk safely to work.

Prosafe was formed in 1997, when the platform drilling and technical services divisions de-merged from Transocean[clarification needed] as a separate company and became listed on the Oslo Stock Exchange as Procon Offshore 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 2006, the company acquired Consafe Offshore AB, which owned three semi-submersible accommodation/service rigs and one accommodation jack-up.
