Engineers are still trying to find the source of a gas leak that has led to the evacuation of 238 workers from the Elgin PUQ oil platform 150 miles off the coast of Scotland. A two-mile exclusion zone has been set up around the platform.
Shell has said its decision to evacuate workers from a neighbouring platform last night was "precautionary".
Shell is removing workers from two offshore installations close to a Total platform which has been evacuated after a gas leak. The leak on the Elgin PUQ platform, about 150 miles off the coast of Aberdeen, led to the evacuation of all 238 workers.
