GustoMSC, a subsidiary of Texas-based NOV, has launched a series of next-generation heavy-lift cranes called ENSIS, intended for installing the foundations of offshore wind farms of the future.

“GustoMSC’s new series of ENSIS heavy lifting cranes meet the needs of the growing offshore wind foundation market. With monopiles and jackets increasing 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.

The 220 meter long and 55 meter wide heavy lifting crane vessel has 9,500 square meters of deck space and a 5,000 ton rated crane with increased load moment and lifting height which is in an optimized position to balance efficiency and flexibility, according to Offshore Vessel Designer.

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. According to GustoMSC, these capacities exceed current market capacities.

The draft is optimized to be able to operate from common yards and a collapsible A-frame that will allow 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 series.

The company says 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 and present specific possibilities.

The ENSIS 3000 is capable of installing smaller monopiles, pin piles or suction anchors, while the ENSIS 4000 design offers opportunities for the evolving US market and Jones Act compliant vessels , said GustoMSC.
