Norwegian North Sea ro-ro operator Sea-Cargo has completed upgrades to two of its vessels, which the company describes as a significant step toward a more energy-efficient future, focusing on cutting-edge sustainability.
The various measures are expected to result in a reduction of up to 50% in fuel consumption. The two vessels have been operating from the Norwegian West Coast under the names Misida and Misana since 2020. They have been purchased by Sea-Cargo and remodelled at the Western Shipyard in Klaipeda. Design and engineering work was carried out by Marine Design & Consulting, Western Baltic Engineering and Naval Tec.
The integration of wind-assisted propulsion, battery storage, optimised energy management and solar power will significantly reduce emissions and fuel consumption, aligning with Sea-Cargo’s commitment to a greener maritime industry.
Each ship has been fitted with:
- Three rotor sails from Norsepower,
- New optimised propellers from Kongsberg, designed for a 14-knot service speed to improve fuel efficiency,
- Scrubber system from Pureteq, lowering exhaust emissions to the air,
- Upgraded machinery and control systems by Wartsila, including advanced energy saving features
- 1600m2 of solar panels installed on the weather deck cover,
- Battery and frequency converter systems from NES, featuring shore power and peak shaving,
- Power management system from Smart Automation, integrating rotor sails and battery technology for optimal energy efficiency.
The vessels have been renamed Trans Hav and Trans Sol, historical Seatrans names used on the first liner coastal vessels, operating between Northern Norway, Oslo, and Drammen in the 1970s.
