Britain's Centrica has received its first Qatari liquefied natural gas (LNG) cargo, four months after it signed a £2 billion ($3.2 billion) delivery deal with LNG producer Qatargas.

The 266,000-cubic-metre Mozah LNG tanker, one of the world's largest, berthed at Britain's Isle of Grain terminal, bringing the first of 7.2 million tonnes of super-cooled natural gas under the three-year deal.

Energy supplier Centrica owns LNG importing capacity at the Isle of Grain facility, including the phase three terminal, which received its first cargo in late October.

Britain expanded its LNG import capacity last year to diversify sources and grow less dependent on North Sea supply.
