Jan De Nul has picked Remazel to supply the XXL monopile handing equipment for its vessel Les Alizes.
Remazel will deliver a set of cradles, a skidding system and an upending hinge for it’s the new floating installation vessel.
The design of this fully automated monopile installation system is tailor-made for Les Alizes and can operate in challenging weather conditions and harsh sea states.
Les Alizss will use the monopile cradles on deck to store monopiles.
The monopile cradles can automatically adjust their supporting diameter and, if required, can also support the tapered section of the monopile.
The skidding system is needed to optimise the use of the deck and will enable Les Alizes to transport the monopiles in between the monopile cradles and the upending hinge.
The upending hinge can accommodate monopiles weighing over 3000 mega tonnes.
The tub-mounted crane brings the monopile in a vertical position using the upending hinge. Once upended, the monopile is placed into the monopile gripper by the tub-mounted crane.
The monopile installation system manipulates the monopiles entirely hands-free and is fully automated.
There is no need for rigging or adjusting the supporting diameter of the cradles manually.
