Description

The non-propelled floating semi-submersible drilling rig “SHELF-7” was assembled in 1992 at the Astrakhan Marine Shipbuilding Yard (AMSY) but because of lack of financing the building was suspended in 1993. In 2001-2002 LUKOIL planned to build the rig ready and at the same time update to a new modern level as regards power demand, drilling capacity, living quarters etc.

RR Offshore Oy was involved in the project as main contractor and Deltamarin as a partner for engineering.
