THE FUTURE OF SHIPPING
Wind + Solar + Battery Hybrid
Sea-Cargo has completed the comprehensive rebuilding of its vessels Trans Hav
and Trans Sol, marking a major milestone in the company’s long-term strategy to
modernise its fleet and significantly reduce emissions in short-sea shipping.
Significant emission reduction
The rebuild delivers substantial environmental benefits. The latest upgrade reduces CO₂ emissions per tonne transported by around 35 percent, while Sea-Cargo’s upgraded fleet now achieves a total emission reduction of approximately 50 percent. These improvements are the result of integrating wind propulsion, renewable energy production and advanced power management into a single energy system.
Both vessels are equipped with three Norsepower rotor sails, which use wind energy to generate additional thrust. Under optimal wind conditions, the sails can produce propulsion equivalent to roughly 10,000 horsepower, significantly reducing the load on the main engines and lowering fuel consumption. Solar panels installed on the weather deck generate renewable electricity while also increasing protected cargo capacity.
The rebuild was carried out in stages at Western Shipyard in Klaipeda while the vessels largely remained in service. The investment has been enabled through long-term industrial transport agreements, including cooperation with Hydro, demonstrating how partnerships between industry and shipping can deliver practical emission reductions.
