CATS did not give a value for the transaction.

ETS, a 165-kilometer pipeline that transports gas from fields in the southern North Sea to Britain's Bacton gas terminal, is operated by Perenco, which also runs the country's Trent and Tyne gas fields.

CML bought a 30-percent stake in the pipeline from Premier Oil, 25 percent from Centrica and 10 percent from Perenco UK Limited, the company said in a statement.

Premier Oil sold its stake for 23.6 million pounds, it said in a statement on Monday.
