Stena Drilling is one of the worlds foremost independent drilling contractors, a wholly-owned subsidiary of Stena AB. In 1989 and 1996, Stena acquired Houlder Marine Drilling and Ben Line Steamers / Atlantic Drilling respectively, inheriting a rich history and pedigree dating back to the mid-1970s. The acquisitions were strategic in providing Stena Drilling with worthy drilling units, alongside staff and personnel who brought invaluable operational experience and success into the Company. Stena Drilling manages a global business, consisting of four ultra-deepwater drillships and two semi-submersible rigs. In expanding its fleet of well-maintained drilling units, the company has had an active role in the building and conversion of rigs whilst also pioneering some of the most leading-edge technologies and innovations in the drilling world, culminating with the Stena IceMAX, the world's first dynamically positioned, dual mast ice-class drillship, meticulously designed specifically for safe and efficient operations in arctic conditions. Stena Drilling's core business values are focused on care, innovation and performance. The pursuit of these goals looks to ensure positive client relations, exceptional performance within our industry and strives to improve the safety, both to the environment and to all personnel involved.
