Jack-ups for WTIV and O&M

With the X-JACK heavy lift jack-up designs we present our answer to the offshore wind industry’s need for fit-for-purpose, cost efficient yet future proof wind turbine installation vessels.

The design driver is to significantly increase the efficiency compared to existing units in the market, both in logistical lay-out as in pay load capacity, while being lighter at the same time. The combination of an innovative hull shape and vessel layout with well proven jacking and crane technologies from reputable suppliers provides unrivalled heavy lift and cargo capabilities.

The ULSTEIN X-JACK-series is scalable and include four versions:

    • J101, tailored for maintenance and exchange of wind turbines/nacelles;
    • J102, sized for most optimal and cost effective installation of four (4) next generation wind turbines;
    • J103, designed to carry and install six next generation wind turbines to realize even the world’s most remote wind farm locations.
    • J104, is a fit-for-purpose design for offshore wind turbine installation and O&M operations.
