For the time being, there is no way to operate a ship like Tambora without burning fossil fuels – by the ships’ main engine, to thrust the ship forward when there is not enough wind, and by its auxiliary engines to generate the electric power required to illuminate rooms and cabins, keep food fresh, prepare meals, fill dive tanks, and many others. While the usage of diesel cannot (yet) be avoided, we have gone to extreme length to keep it as low as possible. This means lower carbon emissions into the atmosphere. It also means no need for fuel surcharges.
Tambora’s propulsion system has been engineered for maximum fuel efficiency. At the heart is a new, genuine marine engine, which is significantly lower on fuel consumption. The five-blade propeller has been custom-designed and fabricated from a special, stiffer alloy, minimizing power losses due to both internal vibration and unnecessary slip.
- The electrical system, too, has been designed end-to-end with a view towards maximum fuel efficiency, including:
- A range of genuine marine and industrial power generators with different output, allowing us to always choose the most suitably sized engine under different load conditions
- Capacitor banks to smooth power needs and curb peaks
- Over-sized marine cabling throughout the entire vessel, resulting in lower distribution losses
- The exclusive usage of power saving lighting throughout the entire vessel; searching for a conventional light bulb is a futile exercise on Tambora!
- The thermal insulation of all decks and ceilings, and the usage of a white, reflecting paint on the outer hull above the waterline, avoids the vessel’s interior from heating up too much under direct sunlight, so that air conditioners do not need to run so hard to keep temperatures comfortable
