In 2009, SADRA launched a domestically built semi-floatable drilling rig for the Caspian Sea owned by NIOC (National Iranian Oil Company). The semi-submersible platform is able to operate at water depths up to 1,030 metres (3,380 ft) and can drill down to 6,000 metres (20,000 ft) under the seabed.[5] Iran-Alborz (from 2010 called Iran Amirkabir) is operated by Iran North Drilling Co.[6]
