An oil leak has shut down Statoil’s Snorre B platform.
The Norwegian operator evacuated a quarter of its staff after identifying an oil shift under a drilling template and then later a leak.
A spokeswoman confirmed 33 of 136 of the workers on site had been evacuated to a nearby floating accommodation facility.
She said: “Production was shut again on Monday after detecting an oil leak, and as a precautionary measure the platform’s manager has ordered to evacuate some of the people from the platform.”
It is the second time in three days Statoil was forced to shut oil production on the platform, which is located in the northern part of the North Sea. On Saturday, the firm shut production shortly after a subsea robot identified a pit under the drilling template.
The Snorre field is one Norway’s biggest oil producers, averaging 88,000 barrels of oil per day.
