Overview

Project execution

The semi-submersible drilling rig was awarded by Caspian Drilling Company to two subsidiaries of Keppel Offshore & Marine Company with Caspian Rigbuilders and Caspian Shipyard Company.

Caspian Shipyard Company signed a contract with Baku Shipyard LLC for undertaking fabrication of the pontoons and upper blocks for the construction of a semisubmersible drilling rig. Each pontoon's weight is about 2,200 tons; overall steelwork performed together with upper hull blocks and outfittings is about 5,800 tons.

The DSS 38M rig is designed for a drilling depth of up to 40,000 ft and operations in 1,000 m water depth. To withstand high wind speeds in the Caspian Sea, an 800 m self-contained eight-point mooring system was installed.

Equipped with well control piping, BOP handling, and foundations rated for 20,000 PSI, the DSS 38M is among the first shallow water semisubmersibles with the capability to perform drilling in expanded areas of operation in the oil fields of Azerbaijan.

The semisubmersible drilling rig, named after Heydar Aliyev, became the first and the only drilling rig in the world with 1,400 atmosphere system technology. Its carrying capacity is 5,600 tons and displacement is 47,500 tons.
