A semisubmersible offshore drilling unit being built for Sverre Ditlev-Simonsen, Norway, by Gotaverken Arendal, Gothenburg, Sweden, has been chartered to Petro Canada for a five-year period.

The Pacesetter design unit is scheduled to begin exploration in June of 1982. Petro is the second Canadian company to order a Gotaverken rig. In June of this year, Dome Petroleum ordered the yard's GVA 4000 unit which will be built under license by Cammell Laird Yard, Birkenhead, England.
