DECOMMISSIONING INSIGHT REPORT 2016

Norwegian Continental Shelf

• Operators forecast just over 112,600 tonnes of topsides from 14 platforms will be removed over the next decade, all in the Norwegian North Sea.

• The next removal is scheduled for 2018, following the successful single-lift removal of the 13,500 tonne YME platform in August this year by the Pioneering Spirit heavy lift vessel.

• The bulk of activity over the decade is forecast between 2019 and 2024, peaking at close to 43,000 tonnes in 2024.

• Just over 84,700 tonnes of substructure from 12 platforms will be removed between 2016 and 2025, again all in the Norwegian North Sea.

• Substructure removal is due to begin in 2019, with the majority of activity concentrated between 2019 and 2022, but peaking at 30,000 tonnes in 2025.

• The forecast for substructure removal mirrors the forecast for topside removal, with a time lag of around a year.
