(WO) – Subsea7 has won a “sizeable” contract by Dana Petroleum (E&P) Limited for the Bittern offshore oil and gas field development approximately 190km east of Aberdeen in the UK Central North Sea, at a water depth of 90 m. According to a statement, the contract award is worth between $50 million and $150 million.
