Huisman to supply third leg encircling crane for Hanwha-built offshore wind turbine vessel

Hanwha Ocean (ex-DSME) has contracted Huisman to design and build a 2,600-mt Leg Encircling Crane (LEC) for an NG-16000X platform wind turbine installation vessel.

It is Huisman’s third contract from Hanwha following orders for two identical 2,600-mt cranes that will operate on installation vessels under construction for Cadeler.

Huisman, in a press release of September 11, said its LECs are designed to be lightweight, with a high level of positioning accuracy and energy efficiency, with a reduced emissions footprint during installation of increasingly large turbine sizes.

The crane’s small tail swing is said to enable optimized deck space. Its slew bearing is constructed in multiple segments.

The latest crane ordered will also comply with the dual class classification requirements of DNV and KR, as it is intended to support South Korean offshore wind projects.

Huisman’s work scope covers design, engineering and construction of the LEC at its facility in Zhangzhou, China. It should be commissioned in 2027 at Hanwha’s shipyard in Geoje, South Korea.
