The Alpha Cormorant platform partially evacuated after oil leak
The Alpha Cormorant platform and the pipeline system it services were shut down as a precaution after an oil leak in one of the legs on March 2 13, operator Abu Dhabi National Energy Company (TAQA) said in a statement.
The company said it had evacuated 71 of its 145 non-essential staff from the platform, and that everyone was safe and well. Leak was contained in the leg with no release of the hydro carbon into the sea. The leak was discovered during maintenance work at 0940 GMT on Mar 2.
Cormorant Alpha, which was built in 1978, handles about 90,000 barrels per day of crude oil, of which 42,600 are produced by TAQA.
The Cormorant oilfield is located 161 kilometres (100 mi) north east of Lerwick, Shetland, Scotland. Production started in December 1979 from the Cormorant Alpha platform. This platform is a concrete gravity platform of the Condeep type. It has four legs and storage capacity for 1 million barrels (160,000 m3) of oil. The total sub-structure weight is 294,655 tonnes and it is designed to carry a topsides weight of 32,350 tonnes.
On 16 January 2013 and again on the 2nd of February 2013 a "hydrocarbon leak" was reported by the BBC in one of the legs of the platform, closing down the Brent System. No oil had been spilt into the sea. It was reported that it had been contained in the leg of the platform.
It is said that the life span of Cormorant A and Condeep type platforms is some 25 years.Maritime Bulletin http://www.news.odin.tc/
