Havila’s first coastal express vessel sets sail

Towards the middle of December, Havila Voyages’ (Kystrutens) ‘Havila Capella’ embarked on her maiden voyage from Bergen to Kirkenes on the coastal express service.

HAV Group and its subsidiary companies were key contributors towards realising what was claimed to be the ‘greenest’ voyage along the Norwegian coastline, the company said.

‘Havila Capella’ is the first of four vessels being built to rival Hurtigruten on the traditional coastal voyage. The vessel’s NOx emissions are 90% lower than similar vessels and a hybrid gas-electric propulsion system cuts CO2-emissions by 25%, Havila claimed.

“Havila Capella is equipped with the world’s largest ship battery, can sail four hours with zero emissions, and can utilise onshore power supply from hydropower to charge the battery. This allows Havila Kystruten to meet the requirements for emission-free sailing in the Norwegian world heritage fjords several years before the government’s requirements come into force. HAV Group is proud to have played a key role in realising this,” said Gunnar Larsen, HAV Group CEO.

The group’s subsidiary companies, HAV Design, HAV Hydrogen, Norwegian Electric Systems (NES) and Norwegian Greentech (NGT) were all involved in the newbuilding project.

For example, HAV Design designed the vessel, which is fitted with several technological innovations to help ensure the lowest possible operating costs and emissions.

Tailored hull and equipment, developed using a simulator-based ship design system that, amongst other things, took into account weather, wind and wave conditions along the route, resulted in a vessel that is significantly more energy efficient and environmentally friendly than the Norwegian authorities specified in its tender qualifications to operate on the coastal route.

NES delivered one of the world’s largest ship battery packs, as well as a hybrid gas-electric propulsion system and smart control systems for the entire vessel.

The battery pack has a capacity of 6,100 kWh, more than twice as much as the largest battery ferries. NES also supplied the integrated navigation system Raven INS, generators, complete switchboard system, transformers, frequency converters for thruster engines and the ship’s energy management system.

NGT supplied ‘Havila Capella’s’ ballast water treatment system, which is claimed to be the market’s most energy efficient system, with a small environmental footprint.

Furthermore, the on board propulsion system was designed for future retrofitting of hydrogen and fuel cell technology. With hydrogen energy, the ship will be able to sail emissions free for significant parts of the coastal route.

With support from the Norwegian Research Council, Innovation Norway and Enova, Havila Kystruten and HAV Group’s subsidiaries, HAV Design, NES and HAV Hydrogen, are currently developing a high-capacity hydrogen energy system that can be used on board one of Havila Kystruten’s coastal cruise ships.

The project, named FreeCO2AST, is also supported by research institutions Sintef Ocean and Protech.
