Kongsberg Maritime retrofit delivers 23% cut in CO2 emissions for Hurtigruten

One year after completing the retrofit of the first of three Hurtigruten Coastal Express ships to hybrid technology, Kongsberg Maritime reports that service results show that the ship, the 121-meter MS Richard With, has achieved a 23% cut in CO2 emissions.

The refit program for MS Richard With included installation of two hybrid shaft generators, two SaveEnergy 1,120 kWh lithium-ion batteries and two Bergen B33:45V engines. It also has new tunnel thruster motors, a retractable azimuth thruster, and controllable pitch propeller blades, plus digital management systems.

Hurtigruten announced its plans for the upgrades back in May 2021 (see earlier story) and last year Kongsberg Maritime partnered with Myklebust Verft shipyard to convert the three ships to hybrid technology, promising both reduced emissions and quieter operations. The 1993-built MS Richard With was the first of the three to be relaunched, in August last year. The second, MS Kong Harald, returned to service in May, and the final ship, MS Nordlys will be complete in 2025.

The project is one of the largest of its kind in Europe, with an investment value of approximately EUR 100 million (about $105.5 million).

“We have built our last fossil fuel ship for the Norwegian Coastal Express,” said Hurtigruten Coastal Express CEO Hedda Felin. “We had the opportunity to upgrade the fleet and give the ships the best of today’s technology. Plus, it’s more environmentally friendly to retrofit a vessel than to scrap and build a new one.”

“We can do the full turnover of a vessel in four or five months. An entirely new build takes much longer,” said Geir Oscar Løseth, Kongsberg Maritime’s vice president of sales aftermarket advanced offerings. “The vessel is also safer and smoother in the water. It gives the crew several layers of reassurance. They can operate on full battery, zero emission operation; they can run on auxiliary engines and they can run on main engines. So, there’s a high level of safety that meets the new requirements for lower-emission travel along the coast.”

Like Hurtigruten, ship owners and operators around the world are working to deal with IMO regulations on emissions reduction, particularly for existing vessels.

“Our role is going to be to guide customers through this transition, with advisory services as well as the products and solutions that will make sure regulations are met. But we won’t do that simply by coming up with new products and solutions. We also need to look into existing fleets,” said Lisa Edvardsen Haugan, president of Kongsberg Maritime.
