INNSTALLATION

The concept idea is based upon two main assumptions:

 

1) That onshore assembly of turbines is less expensive than doing it offshore

2) That floating vessels with no depth limitation and no jacking time will install faster than jack-up vessels - especially on larger wind farms far offshore

 

Floating vessels can be used because the heavy structures are connected in just a few seconds. Advanced roll and pitch control systems and a crane with dedicated compensation system will assist the subsea interface connection.

No human is involved close to the interface and no bolt and nut must be tightned - the water pressure is doing the job. Optionally a wet-mate cable connection can be developed and installed subsea for very quick energyzation.

This innovative technology may reduce installation time by 30-50% compared to present solutions.

 

This type of vessel and crane is one of many possible concepts
