Sakhalin II Tow-out

Fugro Global Environmental & Ocean Sciences (Fugro GEOS) has played a key role during the tow-out, positioning and installation of two Concrete Gravity Base Substructures (CGBSs) for the Lunskoye A (LUN-A) and Piltun-Astokhskoye B (PA-B) platforms for the Sakhalin II Phase 2 Project for Aker Marine Contractors.
Phase 2 of the Sakhalin II Project entails the further development of the PA field (an oil reservoir with associated gas) and the development of the Lunskoye field (a gas reservoir with associated condensate). Both CGBSs, amongst the largest concrete structures ever built in Russia, were towed from the dry dock at Vostochny near Vladivostok to their installation positions off the north-east coast of Sakhalin Island.
The Weather Forecasting Division supplied senior meteorologists to provide real-time weather information. They were based onshore for the tow from the port to the holding area and then accompanied the tow based on a support vessel. The Measurement Division was involved in measuring waves, current profile and water level during the tow-out and installation of the two gravity-based platforms. Both were contracted to Aker Marine Contractors.
