Offshore ship designer GustoMSC, part of NOV, has launched a series of next-generation heavy lifting cranes called ENSIS, intended for installing the foundations of offshore wind farms of the future.
“GustoMSC’s new series of ENSIS heavy lifting crane vessels meet the needs of the growing offshore wind foundation market. With monopiles and jackets getting bigger and bigger in size and weight and the continued need for efficiency in installation, a new generation of vessels is needed,” GustoMSC said.
The company said its ENSIS series features scalable, customizable designs and next-generation crane and bridge mission equipment developed by other groups in NOV’s Marine & Construction business unit.
The ENSIS 5000 design is the largest and most capable of the series to date, GustoMSC said. According to the company, the heavy-duty crane vessel is approximately 220m long and 55m wide, with 9,500m2 of deck space.
“A 5,000t capacity heavy duty crane with increased load moment and lifting height is in an optimized position to balance efficiency and flexibility.” The vessel is designed around a top hinge combined with a motion compensated clamp that allows the ENSIS 5000 to take up to six XXXL monopiles in a single trip. These capabilities exceed current market capabilities,” GustoMSC said.
According to the designer, the project is optimized to be able to operate from common yards, and a foldable A-frame allows mobilization around the world.
In addition, GustoMSC said the latest energy saving, recovery and storage solutions and new or alternative fuels are ready to be integrated into the ENSIS 5000.
“The ENSIS 3000 and ENSIS 4000 designs are based on the same principles and expertise as the ENSIS 5000, but are developed to meet particular challenges or present specific possibilities. The ENSIS 3000 is a compact design that efficiently installs smaller monopiles, pin piles or suction anchors, while the ENSIS 4000 offers opportunities for the evolving US market and Jones Act compliant vessels,” added GustoMSC.
