Wind Energy – LEC
Huisman has announced the signing of a contract with Daewoo Shipbuilding and Marine Engineering (DSME) for delivery of another 2,600mt Leg Encircling Crane (LEC).
This follows a previous order, in July last year, for a similar crane. This crane will be installed on the second Wind Turbine Installation Vessel ordered by Eneti and constructed by DSME.
The LEC will be outfitted with a 155m boom, which – similar to the first crane – was extended to reach an unparalleled lifting height of 174m above deck. This brings the hook height to approx. 215m above LAT. This, combined with its 2,600mt lifting capacity, gives the crane a degree of future-proofing, preparing it for handling the next generation of wind turbine, with up to 20MW capacity.
Huisman has designed its LECs to meet the requirements of the continually developing offshore renewables sector. The cranes are lightweight, have high positioning accuracy and are highly energy efficient, contributing to a reduced emissions footprint during operations.
The crane features a small tail swing, offering optimal deck space. The theme of efficiency is continued in the design of the slew bearing. Its construction in multiple segments ensures ease of inspection and maintenance.
