Dubai Drydocks to build hulls for Aker semis

Aker Kvaerner last week signed a contract for the hulls of two H6e semisubmersible drilling rigs to be built by Dubai Drydocks.

The rigs have been ordered from Aker Kvaerner by the recently formed Aker Drilling.

The contract with Dubai Drydocks includes the steel construction of the two hulls up to main deck, installation of piping systems, DP systems, mud tanks and sophisticated hull and tank coating as well as extensive electric wiring work.

The major sections of the rig hulls, pontoons and columns will be built in separate units and assembled with bracings in one of the yard's graving docks. The dimensions of the finished hull structures are: Length--120 m Width--77 m height --37.5 m

After completion of work at Dubai Drydocks, the hulls will be transported to Aker Kvaerner Stord yard at the west coast of Norway, for installation of deck structure with drilling equipment, accommodation and final commissioning.

The hulls will be built to the highest DNV standards for offshore construction, which require special steel qualities and strict welding requirements, for the entire steel construction.

In total, each hull will have a steel weight of 16,300 tons and the production time is scheduled to be 12 months, after first plate cutting in May 2006, with delivery of the first unit in June 2007 and the second unit 8 months later.
