GSP Saturn drilling rig was designed by Sonat Offshore and was built by Petrom at the Galaţi Shipyard in 1988.
[2] The rig was owned and operated by Petrom from 1988 to 2005 when the company sold its six offshore platforms (including Atlas, Jupiter, Orizont, Prometeu and Saturn) to Grup Servicii Petroliere for US$100 million.
GSP Saturn 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 12 metres (39 ft) waves and 155 kilometres per hour (96 mph) winds.
[1] Currently the GSP Saturn is operated by the Dutch company Wintershall Noordzee.
