Thialf-Plet Support Tower

An enormous steel structure for the crane vessel Thialf

Heerema Marine contractors



For the crane vessel Thialf we supplied the steel structure of the PLET Support Tower.

The contract consisted of: 
• support tower
• base section
• A-frame
• workshop
• stinger frame
• stinger hinge
• hang off table including corresponding steps and platforms

The work includes fabrication, assembly, testing and load–out of the structure. The project was carried out by ASK Romein as a Design & Build where the detailed engineering was carried out in parallel to the construction phase. We worked very closely with our client from start to finish. In spite of the many changes that were requested as the work proceeded, we succeeded in installing the structure on board the Thialf within 8 months after awarding of the contract.
