Name: Orlan Platform
Location: Offshore Sakhalin Island, Russia
Company: ExxonMobil
Orlan is the first production platform installed a the Chayvo field on the Sakhalin shelf, approximately 11 kilometers off the east coast of Sakhalin Island.
The Orlan platform is a gravity base structure (GBS) set in around 14 metres of water. The platform consists of three basic components: a steel Mudbase, a concrete mid-section called Brick and steel deck Barge section which supports the drilling rig, platform facilities and accommodation quarters.
The Mudbase consists of a series of large tanks that can be flooded with seawater, thereby providing ballast control during the towing or refloating of the platform. Once on the seabed, the tanks are completely filled to obtain the maximum gravity load. The concrete Brick, situated on the Mudbase, is the main structural element, which can withstand gigantic ice ridges. The Brick supports the top deck Barge. The connection between the units is by gravity and there are no rigid connections.
Installation of the Orlan platform was completed in July 2005 and drilling operations commenced in December 2005.
