Swell Compensator System Lifts Crane Capacity
01 Oct 2005
Hytop BV has designed, produced, delivered, tested and operated two swell compensator systems which will enable Genius Vos to handle heavy loads on the open sea. Key to the system is ensuring that a crane which can take a 280 ton static lift load but is not equipped to respond to rapidly changing loads does not experience more than 50 tons jump load while 150 ton platform structures are being lifted from a supply vessel at sea.
To prevent this potential overload, Hytop developed a tensioner system which allows the crane to lift structures from the deck, compensating for the heave of the sea, enabling dynamic loads to be gradually transferred to the crane so that the full static load could be taken on the hook, with the load clear of the supply vessel.
The cylinders in the compensator systems have a dynamic load capacity of 115 tons and a stroke of 4m, enabling operations to be carried out in sea states of 3m.
The tensioners could be designed for larger lifts if required and will also be helpful for installing offshore wind turbines.
