Sea-Cargo retrofitting RoRo pair to cut fossil fuel use by up to 50%

Norwegian shipowner Sea-Cargo has decided to remodel two of its roll-on/roll-off (RoRo) ships in an effort to achieve a reduction of up to 50% in fossil fuel consumption.

The two 165-meter vessels in question are Misida and Misana which operate mainly between Norway and continental Europe.

The transformation will focus on sustainability initiatives and technological upgrades which are planned to be performed in the summer of 2025.

“Through the implementation of these measures, we anticipate a reduction of up to 50% in fossil fuel consumption,” Sea-Cargo said.

As informed, the retrofit will include:

• 3 new 24x4m rotor sails from Finnish cleantech company Norsepower, harnessing wind energy for the production of additional clean power;
• New optimized propellers from Kongsberg, designed for a 14-knots speed to improve fuel efficiency;
• NoX scrubber by Pureteq, significantly lowering air emission;
• Major upgrade to machinery & control systems from Wärtsilä, including advanced energy-saving features and bridge equipment to compensate blind sectors;
• Covered weather deck, increasing under-deck capacity;
• Solar panels – 1,600-square meter solar panels installed on the weather deck cover;
• Battery and frequency converter systems from NES, featuring an energy pack with shore power
