BERGEN, Norway -- Ophir Energy has contracted Odfjell Drilling’s new ultra-deepwater semi Deepsea Stavanger for Tanzania’s first deepwater drilling campaign.
The contract for the dynamically positioned rig was signed on behalf of the blocks 1, 3, and 4 joint ventures in Tanzania that Ophir operates in partnership with BG Group.
The program is due to start later this year – the rig leaves the DSM shipyard in South Korea in July and should arrive in Tanzania during August. The $50-million contract calls for two firm wells to be drilled with provision for a third.
According to Odfjell, both the Deepsea Stavanger and its sister rig Deepsea Atlantic are designed with an environmental focus. Features include a clean drain system with controlled discharge to sea; low NOX emission engines; an enclosed derrick; and cuttings re-injection. The rigs can operate worldwide, including harsh environments, and in water depths up to 3,000 m (9,842 ft).
