SeaZero

Summary

Short description

The project’s primary objective is to cut the ship’s energy consumption in half. The final report shows that energy use can be reduced by around 40-50% through a range of innovative onboard solutions. Through the Sea Zero project, we have worked with a holistic approach to energy use, focusing on production, distribution and reduction of heat demand. By integrating efficient heat production through heat pumps, optimizing energy distribution, and minimizing unnecessary consumption, substantial savings have been achieved without compromising onboard comfort.

Furthermore, the optimization of demand-controlled ventilation systems, providing comfort on demand, has proven critical in avoiding unnecessary energy use for the transport and treatment of excess outdoor air. Through pilot testing onboard MS Trollfjord, we optimized our Smart Cabin solution, featuring individual temperature control, integration with the booking system, and fully automatic presence detection.

This holistic approach has also highlighted the importance of early-phase system integration. By involving HVAC and hotel systems at an early stage of the design process, with real influence on vessel design, it has been possible to unlock synergies that would not be possible through isolated system improvements. The results demonstrate that energy efficiency must be embedded as a core design parameter from the outset to enable zero-emission operation.
