ExxonMobil - Berkut Platform (Sakhalin Island I)

The Sakhalin project, one of the largest in Europe, is located onshore and offshore of Sakhalin Island, a remote territory of the Russian Far East with a water depth up to 48 m / 158 ft.

 

 

ExxonMobil Sakhalin II

After years of planning, engineering and construction, the Berkut platform was installed on the Arkutun-Dagi field and began operations on June 27, 2014.

 

William Jacob Management contributed to the success of the Arkutun-Dagi offshore project, an offshore oil and gas development on Sakhalin Island located on the east coast of Russia. The massive production platform was previously under construction at the Daewoo Shipbuilding and Marine Engineering (DSME) yard in Korea.

Located in sub-arctic waters, the Sakhalin Island Berkut platform is one of the largest floatover platforms in the world!

The Sakhalin I project is a consortium between ExxonMobil affiliate, Exxon Neftegas Limited (ENL), Sakhalin Oil and Gas Development Co. Ltd., ONGC Videsh Ltd., Sakhalinmorneftegas Engineering LLC (SNE) and RN-Astra to locate and produce oil and gas onshore and offshore the Russian Sakhalin Island from three fields - Chayvo, Odoptu, and Arkutun-Dagi. The total project is estimated to cost US$10–12 billion, making it the largest direct investment in Russia from foreign sources.


The Arkutun-Dagi Field, is one of the three offshore fields to be developed by the Sakhalin-1 project, which when combined with the Chayvo and Odoptu fields has recoverable reserves of 2.3 billion barrels of oil and 17.1 trillion cubic feet of gas. All three fields are being developed by the Sakhalin-1 Consortium and operated by Exxon Neftegas Limited. Arkutun-Dagi is located approximately 15.5 miles east of the Chayvo Field offshore Sakhalin Island.


William Jacob Management partnered with Worley Parsons and Parker Drilling in the overall design of a complete drilling package for the Arkutun-Dagi offshore platform topsides/drilling rig project, including the derrick, pipe barn, substructure, well control system and mud system. William Jacob Management engineers also offered support and supervision to ensure a seamless integration of the drilling systems with the main topsides design.


Located in sub-arctic waters this will be one of the largest floatover platforms in the world. The Arkutun-Dagi development has an offshore, ice-resistant fixed platform which is also the largest oil and gas production platform in Russia. This gravity-based structure has been named Berkut - from the Russian for golden eagle. The Berkut structure is designed to operate year-round and to withstand extreme winter temperatures, seismic shocks, seas up to 52 ft, and sea ice that can be as much as 6.5 ft thick. Water depths at Arkutun-Dagi range from 49-131 ft.


The Berkut platform is the first ExxonMobil operated platform with friction pendulum bearing isolators to make it more seismically stable. Its topsides are among the largest in the industry, weighing about 28,000 tons.


Berkut is planned to depart from DSME in May 2014 and first oil is expected to be produced later that year.
