Sakhalin II Onshore Processing Facility (OPF)

PROJECT LOCATION

Sakhalin - Russia

CLIENTSakhalin Energy Investment Co.

CONSTRUCTION PERIODMay 2003 - July 2009

PROJECT VALUEUS$ 1.1 Billion

PROJECT DESCRIPTIONThe Sakhalin II Onshore Processing Facility, located in the Nogliki district, 7 km inland in the north-east of Sakhalin Island, is the first combined oil & gas processing facility built in Russia and the largest of its kind globally. It is the key element of the Sakhalin II integrated oil and gas field development project, producing oil and gas from two major offshore fields located on the northeastern shelf of Sakhalin Island in the Okhotsk Sea.

The scope of work included the design and construction of buildings, multi-discipline fabrication, construction and erection works and provision of commissioning and start-up assistance for the whole facility; and also procurement of bulk materials; material management; transportation and logistics of all process equipment and materials sourced worldwide and free-issued by the client.

Sakhalin Island - Russia

CLIENTExxon Neftegas Ltd.

CONSTRUCTION PERIODJune 2005 - October 2006

PROJECT VALUEUS$ 94 Million

PROJECT DESCRIPTIONIn May 2005, ENKA was awarded the contract for the installation of the mechanical and piping systems for the Onshore Processing Facility by Fluor Daniel Eurasia Inc. the EPCM Contractor, on behalf of Exxon Neftegas Limited.

ENKA scope comprised the erection and installation of various static and rotating process equipment including compressors, generators, heat exchangers, boilers and pumps; field erection of 40,000 tons of prefabricated modules weighing between 900 and 2,500 tons and field erection of 4,100 tons of steel as well as 40,000 m of field piping, including fitting, welding, pressure tests, painting and insulation. ENKA also performed all scaffolding and winterization works for all disciplines at the Onshore Processing Facility Site & Orlan Platform during the project and provided commissioning and start-up support to the client.

ENKA not only performed the hook up of these prefabricated modules, but also a substantial amount of stick built site erection work during very harsh two winters, including required field modifications to prefabricated modules and erection of their loose delivered parts, erection of freestanding equipment, various stick built pipe racks and all interconnecting piping works. ENKA also provided plant commissioning and startup assistance to the client.
