DNV has actually granted the Norwegian modern technology carrier HAV Group ASA initial authorization for its hydrogen-based power system. The system utilizes melted hydrogen storage space as well as gas cells as well as was produced as component of the FreeCO2ast task, which is presently creating a high-capacity hydrogen power system that can be retrofitted onboard 2 seaside cruise ship vessels had by the Norwegian driver Havila Kystruten.

The initial authorization via DNV suggests that HAV Group ASA can with confidence go into the last layout phase as well as is one action better to marketing its hydrogen system.

Green hydrogen can play a vital function in the decarbonization of delivery– both in regards to its possible as an enabler for artificial gas, along with its straight usage as ship gas. However, hydrogen’s special homes make it a complicated gas to deal with, as well as the absence of authoritative guidelines suggests that business wanting to introduce hydrogen systems require to adhere to the IMO standards on different layout (MSC.1/Circ1455). As with all arising gas, the upkeep of high security degrees when utilizing hydrogen is critical.

“The Alternative design approval process is used for novel ship designs that cannot be approved with the current prescriptive regulations and the final approval is granted by the Flag State. 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,” described Ivar Håberg, Director of Approval, Ship Classification, DNV Maritime.

He included: “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 fulfils 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.”

Gunnar Larsen, CHIEF EXECUTIVE OFFICER of HAV Group ASA, stated: “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. Getting to this stage has been the result of four years of cooperation with our internal and external partners in the FreeCo2ast project and excellent support from experts at DNV. Their guidance has been essential in successfully navigating the Alternative Design process.”

In a different task, DNV advising specialists sustained HAV Group ASA with Hazard Identification (HAZID research study) as well as Quantitative Risk Analysis (QRA) for every single facet of their hydrogen gas system, consisting of bunkering, tank, the gas supply system as well as various other supporting systems that are linked to the hydrogen system aboard the vessels.
