SeaDream has received a grant for $1.8 mill to go twards the construction of the ‘SeaDream Innovation’ from Enova, which is owned by the Norwegian Ministry of Climate and Environment that is responsible for the promotion of environmentally friendly production and consumption of energy.

“We are extremely grateful that Enova supports our environmental efforts. Without this solid support from Enova, this would not have been possible,” said Atle Brynestad, SeaDream’s owner. “We are proud to contribute to the cruise industry by taking the lead in developing more environmentally friendly vessels that will also sail with the Norwegian flag.

“We are committed to having a positive impact on the environment, our employees, our guests, our suppliers and the places we visit. In the future, we all need to make a positive contribution to our environment and the local communities we visit, so guests can continue experiencing different local communities and enjoying the fantastic nature while using local services and making local purchases where possible,” he added.

‘SeaDream Innovation’ will be fitted with a large battery pack of around 4 MW/h, which will enable the vessel to sail silently and without emissions for up to three hours with no disturbance to surrounding wildlife.

The hybrid system will reduce local emissions by supporting the diesel generators in ‘peak shaving mode’, reducing fuel consumption. Due to the fitting of this system, the vessel will be able to sail to sensitive areas, such as the Norwegian fjords and along the ice edge toward the North Pole.

The batteries also bring an added degree of safety, acting as ‘spinning reserve,’ which in the event of anengine shutdown, switches instantaneously to the the batteries without loss of power.

“Batteries have entered the maritime sector, but until now, there has been little experience to show in practice, especially in cruise ships,” said Enova’s CEO, Nils Kristian Nakstad. “When it comes to electricity production of surplus heat, land-based industry has shown what is possible, but at sea, such solutions are currently used very little. We depend on more people developing and using these technologies the world needs.”

‘SeaDream Innovation’ will also be equipped with an‘Organic Rankine Cycle’system that takes waste heat from the engines and converts it to electricity. This can produce up to 150 kW of electrical power, which would otherwise have been wasted energy.

Where available in a port, the vessel can also can be plugged into shoreside electrical grids worldwide by using a multi-voltage shore connection system.

The mega-yacht will house four diesel engines and a selective catalytic reduction (SCR) system for reducing NOx emissions to the most stringent IMO rules. The engines will be rated to meet the latest and most stringent MARPOL Tier III limits.

She will be powered by two podded propulsors providing the highest efficiency and manoeuvrability. Additionally, ‘SeaDream Innovation’ will be designated asIce Class PC6.
