They are also among the most sophisticated semi-submersibles in the industry. MÆRSK EXPLORER began drilling in the Caspian Sea in 2003 and since then we have optimised their design and increased both drilling depth and production capacity. The newest rigs are capable of drilling 10,000 m (30,000 ft) into the sub-soil measured from the seabed. This makes the rig particularly well-suited to drilling in deep and geologically complicated areas like the Gulf of Mexico.
Marsk Drilling's semi-submersibles have superior offline capabilities supporting efficient and safe operations to the benefit of the customer.
Time saved in the drilling process allows for earlier production and lower well costs
Our semi-submersibles are capable of operating in depths up to 3,000 m (10,000 ft) and maintain their station either in dynamic positioning (DP) mode or with a pre-laid mooring system.
Our new generation of semi-submersible rigs features state-of-the-art drilling technology. They include a number of innovative features, which enhance the rigs' flexibility by making multiple concurrent activities possible. Back-up facilities and solutions are generally provided to reduce the impact of equipment failures, and the hull design and layout are based on the operational experience of various deepwater operators and third party system suppliers. We have incorporated a series of innovative ideas from our potential customers.
Our highly advanced deepwater development semi-submersibles are capable of operating in ultra-deep water up to 3,000 m.
