Ulstein’s second hydrogen hybrid design for the offshore wind trade, the ULSTEIN J102 zero emission wind turbine set up vessel (WTIV), can function 75% of the time in zero emission mode. Using available
know-how, the extra value is restricted to lower than 5% of the overall CAPEX.
Most new jack-up designs are that includes a battery hybrid system along with diesel gen units, with a future possibility for hydrogen powered gasoline cell system. The draw back nevertheless of a high-power battery power storage system (BESS) is its heavy weight and value. That isn’t helpful for a WTIV design, the place weight financial savings are important for minimizing Elevated Weight and optimising the Variable Deck Load.
Rather than to go for know-how to be matured to perfection and make a design that’s ready for future hydrogen powered gasoline cells, Ulstein has taken the pragmatical, but life like method. “We have fastidiously analysed the operational cycle of WTIVs and regarded on the energy demand within the numerous modes of operations”, says Ko Stroo, Product Manager at Ulstein. “This evaluation confirmed that ca. 75% of its time, a WTIV is in jacked-up place performing crane operations. Using a mixture of a hydrogen gasoline cell system and a comparatively small battery power storage system (BESS) is then ample to fulfill the general energy demand on board and crane peak hundreds.”
“The similar design philosophy as on our first hydrogen powered SX190 design, resulted in a way more engaging enterprise case when utilized to a turbine set up vessel”, states Edwin van Leeuwen, managing director of Ulstein’s Rotterdam design workplace.
The hydrogen hybrid system of the ULSTEIN J102 design has been developed in such a method, that future developments in hydrogen know-how can simply be fitted into the vessel with out main modifications. “The restricted availability of hydrogen bunker infrastructure in ports is commonly seen as a significant hurdle. With our modular storage lay-out, we wish to break the rooster and egg dilemma’, continues Stroo. “It creates flexibility to function the vessel worldwide, even when bunker infrastructure isn’t but current.”
