Neptune Energy has completed the removal of three veteran platforms in the Dutch sector of the North Sea that have been decommissioned.

The L10-C, L10-D and L10-G facilities, which have been producing natural gas to supply the Netherlands for the past 40 years, ceased production operations in 2016.

The removal job carried out by Dutch contractor Boskalis started earlier this year but met with disruption due to the Covid-19 pandemic as quarantine and travel restrictions hit offshore manpower logistics for the wider industry.

The topsides and jackets of the platform trio weighing a total of more than 3400 tonnes — around half the weight of the Eiffel Tower in Paris — were safely removed from the field and transferred to Boskalis’ heavy-lift and transport vessel Bokalift1 in the extensive operation using the vessel’s 3000-tonne crane.

Rocks have also been removed to return the seabed to a clean state.

“The work was completed in a safe and secure way, both for the crew and for the environment. All three platforms were brought onshore and the associated materials will be recycled or reused as much as possible,” said Neptune’s managing director for the Netherlands, Lex de Groot.

Boskalis Offshore Heavy Lifting managing director Marcel van Bergen said: “During the start of the activities, the world and this project were confronted with Covid-19 and we appreciate the great co-operation between all parties involved to adapt to the challenges and complete the job in a safe manner.”

The L10 Area continues to produce gas from a number of facilities centred on the Neptune-operated L10-A platform.
