(Adds maintenance plans at Dornum, Emden, St Fergus terminals,
OSLO Dec 16 Norway's largest gas-processing
plant, Kollsnes, will be partially shut from May 6-20 and from
Sept. 2-20 next year, gas system operator Gassco said on Friday,
announcing its 2017 maintenance plans.
Norway exports natural gas from its offshore fields via a
dense network of subsea pipelines to Britain, Germany, France
and Belgium after processing it at onshore plants.
Norwegian gas meets about 25 percent of Europe's demand.
The Kollsnes plant in western Norway processes gas from the
country's biggest offshore field, Troll, a key gas supply source
for Western Europe.
The partial shutdown will reduce the plant's daily
production capacity of 144.5 million cubic metres (mcm) by 38.5
mcm, Gassco said on its website.
The plant and the Troll field will be shut completely for
one day on May 15, it added.
Maintenance plans showed most of Norway's capacity
reductions will occur in June and September, while the total
scope was smaller than in 2016.
Gas import terminals at Dornum and Emden in Germany were
expected to be shut for yearly maintenance on May 6-24, while
maintenance at St Fergus terminal in Scotland was to reduce
export capacity by 5 mcm/day for three months starting July 1.
There were no plans announced for annual maintenance at the
Troll field, Kaarstoe or Nyhamna gas-processing plants.
Gassco was not immediately available to comment.
