Flows via the pipelines are expected to be lower during the inspections and could tighten supplies to the UK network, lending support to prompt natural gas prices, traders said.

Bu Samra vessel arrived at the South Hook terminal in Milford Haven earlier in the day, while Ruby LNG vessel is expected to dock at Dragon terminal in the coming week.

These vessels are the latest in a series of LNG cargo arrivals in the UK in the last six months, which has significantly increased the supply of gas into Europe from the Middle East, depressing UK prices.

Dragon LNG and South Hook LNG terminals, both in South Wales, between them have a capacity to supply up to 25% of the UK’s gas requirements. Both the terminals were fully commissioned this year.

UK’s oldest LNG import terminal, the Isle of Grain, can import 9.8 million metric tons of LNG every year.
