SCHIEDAM, the Netherlands – Daewoo Shipbuilding & Marine Engineering Co., Ltd. (DSME) has commissioned Huisman to deliver a 2,600-metric ton leg encircling crane (LEC) for Eneti’s newbuild wind turbine installation vessel (WTIV).
The scope of work consists of the design, engineering, and construction of the LEC and pedestal adapter at its production facility in Zhangzhou, China. Commissioning and testing of the LEC is scheduled for 2023 at the DSME shipyard.
The contract also includes the optional delivery of a second crane, intended for an identical WTIV.
The LEC has a 147-m (482-ft) long boom, capable of reaching 170 m (558 ft) above deck. With its 2,600-metric ton (2,866-ton) lifting capacity, the crane is expected to be able to install up to 20-MW turbines.
Features and benefits of the LEC include:
- A fully electrically driven system, which is said to result in high positioning accuracy, efficient energy use, reduced maintenance and high reliability.
- In-house developed slew bearing system, which provides reliable and accurate positioning of the crane.
- A unique Lambda boom design is said to ensure a lightweight and stiff design.
- Stiff construction of the Lambda shaped boom leads to reduced motion at the crane tip.
- Small tail swing allows for optimized use of free deck space.
