Oil platform in the Baltic Sea Dismantling – Piece Small

To remove the Schwedeneck platform from the German part of the Baltic Sea, we worked together with the client and used a seagoing crane pontoon. The ‘Piece Small’ method was used, breaking the platform up into small pieces on site and then transporting them away.

Dismantling, cutting with torches and shears on hydraulic excavators: the platform was dismantled and carried away. The extremely large pieces such as the helicopter deck were taken by floating cranes, the larger pieces on pontoons and the smaller ones in containers. Everything was then processed and disposed of on dry land.

Once the topside had been fully removed, air was pumped into the cylinders of the foundation structure so that the platform would float – stabilised with various pumps and ingenious systems. Tugboats then took it to the quayside for further demolition and disposal. All materials was separated at the source and taken away.
