Huisman has developed a 700-metric-tonne Travelling Quayside Crane for the load-out of offshore wind turbine components. The move comes as a result of rising demand for large, 2600-mt and 4000-mt Skyhook Cranes for the load-out of foundation pieces and installation of floating turbines.

With the 700-mt Travelling Quayside Crane, the load-out process of offshore wind turbine components can take place significantly faster compared to the regular methods that involve crawler cranes, or a tandem-lifting by two cranes with a capacity around 200 to 300 mt.

Fully electric

The new Quayside Crane has been designed fully electric, allowing for a direct connection to the quayside power grid. This allows regenerative energy to be directed back into the utility grid, thus drastically limiting the net energy consumption of the crane.

Although the crane is designed to travel on a track 16 metres wide, this can be adapted to local requirements. Capable of lifting 700 mt at a radius of 25 metres, the crane can bring many turbine components to any place in the hold of the majority of the cargo vessels currently used for turbine transportation.

Increased efficiency

The ability to travel at decent speed with load in the hook enables a more flexible delivery schedule of components to the load-out quayside. This results in a more efficient use of the quayside and a quicker turnaround for the transportation vessel.

‘We see a need in the offshore wind logistics market for increased efficiency in smaller ports in newly developed offshore wind areas,’ says Cees van Veluw, Product Manager Cranes at Huisman. ‘The traditional use of crawler cranes or multiple smaller quayside cranes would require a very large backyard. It also requires the transport vessel to be moored along the quayside for an unnecessarily long time. With this new 700-mt Huisman Travelling Quayside Crane, offshore wind ports can be ready for a quick load-out of turbine components in a sustainable manner.’

Features of the Travelling Quayside Crane

  • A fully electrically driven crane, resulting in high positioning accuracy, efficient energy use, reduced maintenance, reduced noise, and high reliability.
  • Track width of 16 metres, can be adjusted to local requirements.
  • 700-mt lifting capacity at a radius of 25 metres.
  • Dual Main Hoist, allowing for flexible rigging configurations without the need for an extensive portfolio of slings and grommets at hand.
  • A 57-metre long boom, adjustable for other configurations.
  • Cabin “eye level” at 33.5 metres height above the quayside.
  • Optionally, the crane can be equipped with a “lift-off boost” system for increased speed.
  • Design is adjustable for local requirements.
