Norwegian shipping line Hurtigruten has signed a contract with Kongsberg Maritime (KM) to upgrade three Norwegian Coastal Express passenger vessels with comprehensive equipment packages for hybrid operation.
The upgrade is expected to cut CO2 emissions from the vessels, which operate along the coast of Norway, by at least 25 per cent. KM will collaborate closely with Norwegian shipyard Myklebust Verft on the refit.
Each vessel will be fitted with two SAVe Energy 1,120kWh lithium-ion energy storage systems, controlled via Kongsberg Maritime’s SAVe CUBE integrated drive switchboard. This single cabinet solution includes all frequency converters, drives and DC switching equipment necessary for the hybrid system, controlling all connected thrusters, saving space and simplifying cooling and installation.
Two new, energy-efficient Bergen B33:45V diesel engines will propel each vessel, equipped with selective catalytic reduction (SCR) to ensure optimal emissions control and compliance with IMO Tier III regulations, and fully compatible with KONGSBERG’s digital management solutions, including health monitoring. The delivery scope also encompasses reblading of the main propellers, new thruster motors, AC switching, safety and telegraph systems, in addition to full system integration and commissioning.
“This is one of the largest environmental vessel upgrade projects to be undertaken in Europe,” said president Egil Haugsdal of Kongsberg Maritime. “For us, it’s rewarding to work with a company that shares our ambitious approach to technology and environmental issues. These green upgrades of Hurtigruten Norwegian Coastal Express ships represent a forward-looking, sustainable choice for their existing fleet.”
Shaft generators on the engines will supply electrical power, managed by a custom installation of the K-Chief 700 Power Management system. Data from onboard sensors will be collated and shared via the K-IMS (Information Management System) application and analysed using Vessel Insight.
Geir Oscar Løseth, general manager sales, advanced offerings at KM, commented: “Green shipping requires a holistic way of thinking. Optimal operation depends on many solutions working together to ensure that fuel consumption remains low. Every aspect of this project – from the equipment chosen to how it is integrated, installed and used – is equally important to achieving the final result.”
Daniel Skjeldam, CEO of Hurtigruten Group, said: “Our goal is to operate all our ships and all our cruises completely emission-free. While we get a step closer day-by-day, we cannot sit idle and wait for the technology to be in place. We are working closely with our partners, such as the competent team at Kongsberg Maritime, to drive change and move boundaries, while at the same time utilising the best solutions already available today.”
