The ENSIS next-generation heavy lift crane vessel series was introduced by GustoMSC to meet the needs of the growing offshore wind foundation market.
With the increasing size and weight of monopiles and jackets, as well as the ongoing need for installation efficiency, a new generation of vessels is required. The ENSIS series, which is based on an integrated design approach, includes scalable and fully customizable designs as well as next-generation crane and deck mission equipment developed by other NOV Marine & Construction business unit groups.
The ENSIS 5000 is the series’ largest and most capable design to date. The design and development of the mission equipment were guided by GustoMSC‘s advanced engineering analysis skills on motions, dynamic positioning, and mooring, as well as a thorough analysis of the installation process and its requirements.
The heavy lift crane vessel is approximately 220 m long, 55 m wide, and has a deck area of 9,500 m2. A 5,000-tonne heavy lift crane with a higher load moment and lifting height is in the best position to balance efficiency and flexibility. The ENSIS 5000 is built around a combined upend hinge and motion-compensated gripper, allowing it to transport up to six XXXL monopiles in a single trip. These capabilities far outstrip what is currently available on the market. The draught has been optimized to operate from common marshaling yards, and a foldable A-frame allows for global mobilization.
Reducing its environmental footprint
GustoMSC is committed to reducing its environmental footprint. The ENSIS 5000 is ready to incorporate the latest energy-saving, reclamation, and storage solutions, as well as new or alternative fuels.
The ENSIS 3000 and ENSIS 4000 designs are based on the same principles and expertise as the ENSIS 5000, but they have been tailored to address specific challenges or demonstrate specific capabilities. The ENSIS 3000 is a compact design that installs smaller monopiles, pin-piles, or suction anchors quickly and efficiently, while the ENSIS 4000 is designed for the evolving US market and Jones Act-compliant vessels.
