Arkutun-Dagi

The next stage of the Sakhalin-1 Project is the development of Arkutun-Dagi field located at a distance of 25 km from the shore north-east off Sakhalin island and eastward of Chayvo field. The sea depth in the area reaches 40 m.

Arkutun-Dagi operations will be developed in phases, starting with the northernmost part. The crude oil will be sent to the Chayvo Onshore Processing Facility for treatment and then delivered via pipeline to De-Kastri for export.

Exxon Neftegas Limited has successfully and safely completed the installation of the Berkut platform topsides onto the gravity-based structure at the Arkutun-Dagi field in June.

This operation has set a world record for the heaviest integrated topsides installed by float-over method in open sea. The total weight of this giant structure is about 42,000 tons, it contains over 1900 km of cables and over 97 km of piping.

Prior to the installation, the topsides was towed approximately 2,600 kilometers over 12 days without incident from its fabrication site in South Korea. The largest ocean going launch/cargo barge in the world at 260m long and 63m was used for delivery and float-over of the structure.

The Arkutun-Dagi field development will help maintain Sakhalin-1 production. Production startup of Arkutun-Dagi is expected in late 2014.
