Berkut is the world’s biggest oil platform which has begun commercial production at the Sakhalin-1 offshore project in Russia’s Far East. The Berkut oil rig is expected to extract 4.5 million tons of oil annually. The Sakhalin-1 Consortium was formed in 1996 is the first major shelf project in Russia created under terms of a Product Sharing Agreement (PSA). The international consortium is made up of the US major ExxonMobil (30 percent), Japan’s Sodeco (30 percent), Russia’s Rosneft (20 percent) and India’s ONGC Videsh (20 percent). The Berkut platform is expected to produce 12,000 tons of oil daily or about 4.5 million tons annually, raising the total output of the Sakhalin-1 Consortium to 27,000 tons a day.

Offloading equipment from a supply boat is one of the normal lifting operations for offshore rig. Therefore, it is very imperative to follow safety work practices while working with the crane. Crane operators have the responsibility to work with the crane safely. Before any lifting operation, a pre job safety meeting with all crew must be conducted and the plan must be clearly explained to the crew. A banksman will be only one dedicated people to give the signal to the crane operator. While lifting, there must be no one underneath the crane because anything can happen even though a crane is properly inspected.

This video is very good example to learn about the offshore crane failure. The operation was to lift the subsea well head off the boat to the rig. The crane operator picked up the wellhead from the boat. Unfortunately, the crane did not properly function and it resulted in failure. The crane bloom was damaged and fell into the sea. We strongly believe that nobody got hurts from this situation.
