Allseas’ Pioneering Spirit has completed the decommissioning of Repsol Norge’s Gyda platform. Repsol obtained permission from Norway’s Petroleum Safety Authority for the removal and disposal of the platform last September. The removal and transportation of the entire Gyda platform took 12 days and was completed on July 19th, 2022.

Located in the southern Norwegian North Sea, the Gyda offshore oil platform was in use between June 1990 and 2018. The platform’s 18,400-tonne topsides and 11,500-tonne supporting jacket was removed by the Pioneering Spirit, a catamaran crane vessel owned by the Switzerland-based Allseas Group.

A record-breaking lift by a record-breaking vessel

The Pioneering Spirit is the largest construction vessel in the world, with a topside lift capacity of 48,000 tonnes, and a jacket lift capacity of 20,000 tonnes, with six lifting blocks of 5000 t each. Deploying both revolutionary single lift systems, the Jacket lift system and Topsides lift system, the vessel was able to perform a 11,500 tonne, the jacket lift, one of the heaviest in history, and dismantle the platform in a matter of days.The structure was then delivered to a yard in Norway for recycling.
