The Restauration, originally known for carrying the first organized group of Norwegian emigrants to the United States in 1825, is undergoing a significant upgrade to its propulsion system. The ship previously operated with diesel-electric propulsion, where a diesel generator powered two electric motors driving separate propellers. This system is now being modernized with state-of-the-art Oceanvolt AXC36 electric motors, larger propeller diameters for enhanced efficiency, and a substantial 93.6 kWh battery bank.
This modernization, carried out in partnership with Silent Sea, a leader in maritime electrification, enables the Restauration to motor-sail quietly and sustainably for up to 32 nautical miles on battery power alone before the diesel generator is needed to recharge. The silent operation is especially valuable when navigating fjords or entering and leaving harbors, offering a more serene and environmentally friendly experience while reducing noise pollution and emissions.
The upgrade also prepares the Restauration for its 2025 commemorative voyage, celebrating 200 years since its historic transatlantic crossing. Departing Stavanger on July 4, the ship will sail to New York, arriving on October 9. This journey exemplifies the harmonious integration of modern technology into a heritage vessel, honoring its legacy while showcasing how tradition can embrace sustainability to inspire future generations.
