Rambiz, Scaldis’ heavy lift vessel, installed recently the unmanned gas platform L13-FI for NAM in the North Sea.
The 85-meter-long ship has two cranes, shallow draft and large deckspace. The combination of two main cranes enables Rambiz to lift unusual structures that would otherwise require two separate vessels.
The lifting, upending, positioning and driving of the monopile foundation was carried out using the Vibro Lifting Tool.
As explained, the monopile was installed without the use of a gripper frame or installation template.
A vibro hammer drove the pile down to six meters before the target penetration, before an impact hammer completed the job.
Scaldis then installed the column and topside.
