* Statoil shuts Snohvit LNG plant, restart time unknown
* UK gas storage could run out early Feb - trader
LONDON, Dec 22 (Reuters) - British gas futures climbed on Wednesday with concerns over storage levels and Norwegian liquefied natural gas (LNG) production pulling prices up.
Gas for January was up 1.15 pence at 59.15 pence per therm ($9.16 per mmBtu) at 1128 GMT while Summer 11 contracts were up 0.75 pence at 53.45 pence.
Forward prices were firm following an outage at Statoil's STL.OL Snohvit LNG plant due to a technical problem, with no restart date confirmed.
"It's really worrying as it comes at a time when there's likely to be a lot of ships potentially coming to the UK from Norway. This now leaves the UK a bit shorter for the coming month," one gas trader said.

Traders also said UK gas storage was still being used, which was also raising prices for contracts further out.
"Storage is still withdrawing, prices are still telling people to withdraw. Assuming there're no injections over the Christmas period, we'll have around 36 days of storage come the begining of January," another gas trader said.
Traders said thin trade was also making prices volatile, with volumes down as market participants closed positions before the Christmas break.
In the spot market, gas prices were range-bound with ample supply from North Sea gas fields and LNG terminals meeting high consumption from heating demand.
Gas for Thursday was trading between 62.65 - 63.50 pence early in the session, according to one broker.
In the over-the-counter (OTC) power market, prices continued to ease in the run up to Christmas, with baseload electricity for Thursday down 4 pounds at 51 pounds per megawatt-hour (MWh).
The N2EX power exchange settled the auction price for Thursday slighly above the OTC level at 52.52 pounds. (Reporting by Kwok W. Wan; editing by James Jukwey)
