Even sail ships need to decarbonize

Celine Solstad |

Although it may sound contradictory, also sail ships need to decarbonize. Greensight is contributing to the work preparing Statsraad Lehmkuhl, one of the world’s largest, oldest and most beautiful sail ships, for the next decades in operation. A key part of this is to explore how to reduce the remaining emissions from accommodation and engine usage.

The sail ship is the most environmental-friendly sail ship in its class today, but is continuously pursuing the goal of energy self-sufficiency. Being a more than 100 years old lady, this comes with certain challenges and restrictions. Greensight is contributing to the project, delivering a study of the opportunities and potential for local energy production on board at the Norwegian sail ship. The study includes a technology assessment and analysis of potential energy production, as well as an analysis of the current energy demand and possible emission reductions by using new technologies.

Statsraad Lehmkuhl is finishing a worldwide sailing expedition this week, returning from sailing across the globe since 2021 as part of One Ocean Expedition. During the expedition, both the ocean and the life in the ocean has been studied, where they have visited a total of 36 harbours. Naturally, the ship uses sails most of the time, but they also use a fossil fueled engine to maintain velocity, and during harsh weather. In fact, the occasional use of the engine during the expedition lead to total Marine Gas Oil (MGO) consumption corresponding to 1945 tons CO2 equivalents. By use of local power production onboard the vessel, these emissions may be reduced. Greensight will evaluate the feasibility and extent of the emission reductions from local energy production.

To celebrate the return of Statsraad Lehmkuhl, conferences, meetings, workshops and other activities will be arranged in Bergen between 15. -21. April 2023 during “One Ocean Week". Greensight look forward to greeting Bergen's most beloved ship, and of course to getting to know the ship and its operations during this project.
