Dutch company contracted by Daewoo Shipbuilding and Marine Engineering to make second crane of its kind for Monaco wind turbine project

Huisman to build 2,600t Leg Encircling Crane

Huisman will deliver a second Leg Encircling Crane (LEC) with a 2,600-tonne lifting capacity to South Korean shipbuilder Daewoo Shipbuilding and Marine Engineering (DSME) for installation on the second Wind Turbine Installation Vessel ordered by DSME customer Monaco-based offshore wind company Eneti.

The Dutch specialist heavy crane manufacturer said it has signed a contract for the delivery of the second LEC following a previous order in July last year for a similar crane. 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 an approximate 215m above LAT. This, combined with its 2,600mt lifting capacity, prepares it for handling the next generation of wind turbines, with up to 20MW capacity, said Huisman.

The Dutch company added that it 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, said Huisman. The crane features a small tail swing, offering optimal deck space. Huisman will carry out the design, engineering and construction of the LEC, including its pedestal adapter.

Min Yun, head of DSME offshore machinery procurement, said: “We at DSME are very proud to build the second Wind Turbine Installation Vessel for Eneti and feel grateful to have another important opportunity for further strengthening the relationship with our valuable partner, Huisman. We feel confident that Huisman will also take up the important role in this remarkable project and will spare no effort to help construct the world’s highest-class vessel on time."

David Roodenburg, Huisman CEO, added: “We are grateful to DSME and to Eneti for their continued trust in Huisman with this second order for a Leg Encircling Crane. Like Eneti, Huisman is committed to advancing sustainable energy solutions. Therefore, we have developed this crane to support the efficient construction of offshore wind farms. The LEC is designed with both reliability and scalability in mind. It is able to handle not only the current generation, but also the larger, higher capacity turbines anticipated in the future.”
