Disposal Eider Alpha platform topside.
Dismantling and disposal of Eider Alpha platform topside.
About the project
The 12,000-tonne Eider Alpha topside was removed in a single lift by Allseas’ Pioneering Spirit and transported to AF Environmental Base Vats for dismantling and recycling.
A custom-built, 200-metre skid track, levelled with millimetre precision, enabled the safe load-in of the structure. The project targets a materials recovery rate of at least 97%.

Recycling process
AF Offshore Decom sends the recovered metal to a recycling partner whose process emits 85 % less CO₂ than conventional ore-based production due to the use of hydropower as a cleaner energy source for the electric arc furnace. This equates to a reduction of 1.9 tonnes of CO₂ per tonne of recycled metal, which is used in products such as reinforcement steel for new buildings. Marine growth will be composted and turned into topsoil, while hazardous waste is safely treated and disposed of in line with regulations, site permits, and industry best practice.
