Premier Oil Plc will sell its 30% stake in a North Sea pipeline to UK gas infrastructure company CATS Management Ltd for up to $31.68 million, it said on Dec. 11.

The Esmond Transportation System (ETS) pipeline, currently operated by Perenco UK Ltd. transports gas from Esmond Area fields to the Bacton gas terminal on the North Sea coast in Norfolk.

CATS will make an initial upfront payment of $28.1 million payable on deal completion, which is currently expected in first-half 2018.

It will pay up to $3.48 million more if milestones related to development of the Pegasus field are achieved, London-listed Premier said.

Premier said it would use the proceeds to pay down debt. Its net debt stood at $2.8 billion as of Sept. 30.

Perenco and Centrica Plc have also entered into separate agreements to sell their interests in the pipeline to CATS, Premier said.
