HAV Hydrogen H2 System (copyright: HAV Group ASA)
Two coastal cruise ships are a step nearer to having the ability to journey the coast of Norway emissions-free for as much as 20 hours. DNV has awarded HAV Group ASA preliminary approval for a brand new hydrogen-based power system. Using liquefied hydrogen storage and gasoline cells, the system was created as a part of the FreeCO2ast challenge. Part of Norway’s Pilot-E scheme, the challenge is at the moment growing a high-capacity hydrogen power system that may be retrofitted onboard two coastal cruise vessels owned by the Norwegian operator Havila Kystruten.
DNV says that its preliminary approval signifies that HAV Group ASA can confidently enter the ultimate design stage and is one step nearer to commercializing its hydrogen system.
While inexperienced hydrogen might play an vital function within the decarbonization of delivery, DNV notes that hydrogen’s distinctive properties make it a fancy gasoline to work with, and the dearth of prescriptive rules signifies that firms wishing to launch hydrogen programs must observe the IMO tips on different design (MSC.1/Circ.1455). As with all rising fuels, the upkeep of excessive security ranges when utilizing hydrogen is paramount.
DNV’s different design approval course of is used for novel ship designs that can’t be accredited with the present prescriptive rules and the ultimate approval is granted by the flag state, based on Ivar Håberg, director of approval, ship classification, DNV Maritime.
“We at DNV, were very pleased that HAV Group ASA selected us as their chosen partner to carry out a third-party verification review as part of the alternative design approval process,” says Håberg. “Our assessments have shown that the preliminary design complied with the goal and functional requirements in the IGF Code (IMO International Code of Safety for Ships using Gases or other Low-flashpoint Fuels). This means that HAV Group ASA has successfully demonstrated that their concept fullfils the initial criteria for safe and reliable operations with hydrogen as ship fuel. It’s been a pleasure to work with HAV Group ASA, and we look forward to seeing the final design take shape.”
“Getting a hydrogen energy system off the ground is a complex and very challenging undertaking, and we are very proud to have come this far.” says Gunnar Larsen, CEO of HAV Group ASA. z’Getting to this stage has been the results of 4 years of cooperation with our inner and exterior companions within the FreeCo2ast challenge and glorious assist from specialists at DNV. Their steerage has been important in efficiently navigating the Alternative Design course of.”
In a separate challenge, DNV advisory specialists supported HAV Group ASA with Hazard Identification (HAZID examine) and Quantitative Risk Analysis (QRA) for each facet of its hydrogen gasoline system, together with bunkering, storage tanks, the gasoline provide system and different auxiliary programs which are related to the hydrogen system on board the vessels.
