The drilling rig belongs to the Arktikmorneftegazrazvedka exploration company, which carried out work under a contract with energy giant Gazprom.

The drilling rig, which can take up to 102 people on board, was built in 1985 in Finland. The rig started its operations in September to drill and test the Pervoocherednaya well on the West-Kamchatka licensed block of the Okhotsk Sea shelf.

The rig, which is 69 meters long and 80 meters wide, was intended to drill a well at a depth of 3,500 meters.

A Gazprom spokesman said that the rig had fulfilled its works for Gazprom by the time of the accident and was heading for its base.

Investigators have said they are considering the rig's tow in disregard of a severe storm as the most likely reason for the accident.
