DEME awards jack-up vessel contract
DEME has awarded a contract to increase the lifting capacity of its DP2 jack-up vessel Sea Installer.
Huisman has been awarded a contract from DEME for the delivery of a 1,600mt Leg Encircling Crane (LEC) that will increase the lifting capacity of Sea Installer by 700mt. Sea Installer will then be capable of installing the next generation offshore wind turbines for the 800 MW Vineyard Wind 1 project, one of the first large-scale offshore wind farms in the US.
David Roodenburg, CEO of Huisman, said: “We look forward to help maximising the Sea Installer’s performance on the prestigious Vineyard project in the US.”
Bigger and better
Huisman will replace Sea Installer’s current 900mt crane with a 1,600mt LEC, increasing the lifting capacity by 700mt, yet with a limited weight impact on the vessel.
The new LEC has a 140m long boom, capable of reaching close to 160m above main deck, making this Huisman crane ideal for the construction of tomorrow’s offshore wind farms. The boom’s unique design makes it stiff and lighter in weight than comparable booms. Its stiff construction also means reduced motion at the crane tip.
The Huisman LEC features include a fully electrically driven system, resulting in high positioning accuracy, efficient energy use, reduced maintenance and high reliability; an in-house developed slew bearing system, providing highly reliable and accurate positioning of the crane; and a small tail swing allowing for optimised utilisation of free deck space.
The crane will be delivered to DEME from the Huisman facility in Schiedam, the Netherlands.
