Two ships, half the emissions

Written by NES | 25 Mar 2025
Sea-Cargo is transforming two of its key cargo vessels into some of the most energy-efficient ships of their kind. NES is delivering the full battery and energy system for the project.

Misida and Misana are set to become two of the most energy-efficient vessels in their class, with a target of reducing fossil fuel use by 50%. 

The two ships currently operate on conventional diesel. If you live in the Bergen area, you’ve likely seen these green giants sail in and out of the city on a regular basis.

After the conversion, the vessels will be renamed Trans Hav and Trans Sol, honouring the Seatrans legacy while setting a new standard for environmentally friendly industrial shipping.

The upgrade from NES includes:

  • Battery system with shore power and peak shaving
  • New DC switchboards
  • Transformers
  • Engineering and full system integration with automation
  • Variable speed shaft generators
  • Integration of solar panel energy

The result will be a flexible, energy-efficient configuration that reduces emissions without compromising operational capability.

NES previously worked with Sea-Cargo on the pioneering SC Connector, a vessel equipped with tiltable rotor sails. That same hybrid mindset now extends to Misida and Misana—soon to be renamed Trans Hav and Trans Sol.

“Sea-Cargo Skips has proven to be a shipowner that is willing to invest in technologies that can significantly reduce energy consumption, emissions to air and operating expenditure. This approach is an excellent match with our products and service offering,” says Siv Remøy-Vangen, managing director at NES.

The upgrades are being carried out throughout 2025, with NES managing both delivery and system integration.

This is the kind of work we believe in: practical upgrades, proven technology, and real results. One ton of CO₂ at a time. And always in partnership with owners who take energy efficiency seriously.
