GSP Atlas drilling rig was designed by Sonnat Offshore and was built in the Galaţi Shipyard in 1987.[1] The rig was upgraded in 2007.
GSP Atlas has a length of 52.42m (171.98feet), breadth of 40.8m (133.9feet), depth of 6.4m (21feet) and draft of 9.75m (31.99feet), . It has a maximum drilling depth of 7620m (25,000feet) and it can at a water depth of 91m (299feet).[1] As a drilling rig, GSP Atlas is equipped with advanced drilling equipment and has to meet strict levels of certification under international law. GSP Atlas is able to maneuver with its own engines (to counter drift and ocean currents), but for long-distance relocation it must be moved by specialist tugboats. The rig is capable of withstanding severe sea conditions, including waves of 12m (39feet).
