According to Ulstein, the jack-up can operate 75 per cent of the time in zero-emission mode. Using readily available technology, the additional cost is limited to less than five per cent of the total CAPEX, the company said.<\/p>\n
Most new jack-up designs are featuring a battery hybrid system in addition to diesel gen sets, with a future option for a hydrogen-powered fuel cell system. <\/p>\n
A high-power battery energy storage system (BESS), however, comes with downsides such as heavy weight and high cost. That is not beneficial for a WTIV design, where weight savings are essential for minimizing elevated weight and optimising the variable deck load, Ulstein said.<\/p>\n
”We have carefully analysed the operational cycle of WTIVs and looked at the power demand in the various modes of operations,”<\/em> said Ko Stroo<\/strong>, Product Manager at Ulstein. <\/p>\n ”This analysis showed that ca. 75% of its time, a WTIV is in jacked-up position performing crane operations. Using a combination of a hydrogen fuel cell system and a relatively small battery energy storage system (BESS) is then sufficient to meet the overall power demand on board and crane peak loads.”<\/em><\/p>\n This is Ulstein’s second hydrogen hybrid vessel design following<\/a> the SX190 construction support ship. <\/p>\n ”The same design philosophy as on our first hydrogen powered SX190 design, resulted in a much more attractive business case when applied to a turbine installation vessel,”<\/em> said Edwin van Leeuwen<\/strong>, managing director of Ulstein\u2019s Rotterdam design office.<\/p>\n The hydrogen hybrid system of the ULSTEIN J102 design has been developed in such a way, that future developments in hydrogen technology can easily be fitted into the vessel without major modifications, Ulstein said. <\/p>\n ”The limited availability of hydrogen bunker infrastructure in ports is often seen as a major hurdle. With our modular storage lay-out, we want to break the chicken and egg dilemma,”<\/em> said Stroo. <\/p>\n ”It creates flexibility to operate the vessel worldwide, even when bunker infrastructure is not yet present.”<\/em><\/p>\n The post Ulstein designs hydrogen hybrid wind turbine installation vessel<\/a> appeared first on Offshore Energy<\/a>.<\/p>\n world maritime news<\/p>\n","protected":false},"excerpt":{"rendered":" Norwegian shipbuilder and ship designer Ulstein has unveiled a new hydrogen hybrid wind turbine installation vessel (WTIV) design – the ULSTEIN J102.
