Construction of Polarnaya Zvezda Semi-Submersible Drilling Rig

January 18, 2010

At the Vyborgsky shipbuilding plant, the construction of the lower hull of Polarnaya Zvezda is carried out on request of OOO Gazflot. In collaboration with representatives of Flowserve Company (Germany) which supplies packaged propellers (thrusters) for semi-submersible drilling rig, VSP staff started equipment assembly. In the end of December, 2009, preparatory and mechanical works were carried out. In the second part of January, electrical installation assembly of the lower hull are to be finished. Later, engineers of Converteam (England) will participate in the construction.

The upper hull constructed by Samsung Heavy Industry is considered to be finished. There is only one rather complicated stage left — heliport deck lifting. It is to be performed in January.

Samsung Heavy Industry and Vyborgsky shipbuilding plant entered into agreement on partial dock trial of the upper hull facilities on SHI site in the South Korea. There, a part of semi-submersible drilling rig equipment (including drilling machinery) will be brought into operation. The trials are to be accepted by representatives of OOO Gazflot and RMRS. VSP specialists consider that opening the trials in South Korea will save trial time on the test site of interface of the upper and lower hull in Murmansk.
