TECH FILES gen: One Step Closer

LNG Power for VW Car Carriers will be offered to Havila Kystruten for retro? tting. “We will deliver a system that is safe, that takes up little space, that is easy to retro? t and, of course, that does the job,” said Osnes. The development of the hydrogen system is part of a PilotE project in which the Havyard companies and the research institutions Sintef and Prototech are working together.

The head of R&D at Havyard Group, Kristian Voksøy

Steinsvik, said PilotE is useful when it comes to simpli- fying the application process in relation to the range of

Norwegian research and development funding instru- ments, and not least in terms of the support, which less- ens the risk inherent in spearheading the development.

“With PilotE on the team, you can dare to be a ? rst mover at the same time as having a broad focus on de- veloping tools and methods that will bene? t both us and the industry, regardless of the type of technical solution we land on. The system we are developing is designed in modules and can be installed both in newbuilds and ret-
