Piltun–Astokhskoye–B platform

The Piltun-Astokhskoye-B (PA-B), the largest platform of the Sakhalin-2 project, is a drilling, processing and production platform that has been extracting oil and associated gas from the Piltun reservoir since 2008. The hydrocarbons from the PA-B platform flows through the offshore and onshore pipelines to the LNG plant and oil export terminal at the Prigorodnoye production complex. Platform statistics:

The PA-B platform is designed for year-round operation in harsh climatic conditions and is built to withstand rough seas, ice and high seismic activity.
It is located 12 km off the northeastern coast of Sakhalin Island, in a water depth of around 30 m.
Four legged concrete gravity base substructure (CGBS) that was engineered and constructed in Vostochniy port by Aker Kvaerner Technology AS and Quattrogemini OY. PA-B CGBS was installed in August 2005.
Fully integrated deck construction built separately in South Korea, Samsung Heavy Industries construction yard. The topsides were installed in July 2007 on the pre-installed CGBS by float over technique.
With the topsides installed on the base structure, the total height of the PA-B platform is 121 m from the sea floor to the top of the derrick - as large as a 30 storey building.
The platform includes drilling and gas/hydrocarbon liquids/water separation facilities, storage for chemicals.
The living quarters have a capacity for 100 permanent and an additional 40 temporary staff.
Production capacity: oil approximately 70,000 b/d (11,130 m3/d); associated gas 100 mln scf/d (2.8 mln m3/d).
