Ready for turnarounds
Preparations for this year's turnarounds on Statoil's Norwegian offshore platforms and associated terminals have been finalised.
A total of 45 units will be involved in these maintenance shutdowns, reports staff engineer Torbjørn Brekke at the group's Bygnes transport control centre north of Stavanger.
The turnarounds are being coordinated between operators Phillips Petroleum, Saga Petroleum and Norsk Hydro as well as Statoil to ensure that gas deliveries to continental Europe are maintained.
Work on Troll A in the North Sea and its Kollsnes gas treatment plant near Bergen are likely to have the biggest impact on Norwegian gas supplies. While these facilities are shut in, gas production will be boosted from other fields off Norway.
The Troll A/Kollsnes turnaround starts on 1 June and will last 12 days. During this period, Hydro's Troll C oil platform is due to be tied back to the gas system.
Scheduled to come on stream this autumn, Troll C will pipe its associated gas to Troll A for treatment at Kollsnes.
Work at the latter facility includes the tie-in of the Vestprosess pipeline to carry natural gas liquids and condensate from Kollsnes and Hydro's nearby Sture crude oil terminal to Statoil's Mongstad refinery in the same region.
Other Statoil installations due to shut down completely for turnarounds are the Statfjord and Gullfaks platforms in the North Sea. Gullfaks C and Saga's Tordis facilities are the last in the sequence, with a 14-day stop from 15 October. Production will then return to normal.
