The submarines can operate at high speed on diesel power or switch to the AIP system for silent slow cruising, staying submerged for up to three weeks with little exhaust heat. The system is also said to be vibration-free and virtually undetectable. The Type 212 is the first fuel cell propulsion system equipped submarine series. [8] [9]
Most such systems generate electricity, which in turn drives an electric motor for propulsion or recharges the boat's batteries. The submarine's electrical system is also used for providing "hotel services"—ventilation, lighting, heating etc.—although this consumes a small amount of power compared to that required for propulsion.
A hydrogen ship is a hydrogen fueled ship, using an electric motor that gets its electricity from a fuel cell, or hydrogen fuel in an internal combustion engine.. A hydrogen-powered ship is a vessel that uses hydrogen as its primary source of energy, typically through fuel cells or hydrogen combustion engines, to achieve propulsion.
For compactness the ballast tanks were wrapped around the batteries, low down and sharing the flat surfaces of the battery tank. [1] The Kingston valves linking the ballast tanks to the sea could be left open, a practice known as "riding the valves", and the water level in the tanks controlled solely by the vent and blowing air valves. The ...
Many marine vessels do not provide a way for captain and crew to measure and monitor fuel usage while underway. An optimum system onboard would include the ability to instantaneously monitor fuel burn rates from the wheelhouse. Individual engine and generator burn rates would be included, as well as fuel tank levels.
Bunkering is the supplying of fuel for use by ships (such fuel is referred to as bunker), [1] including the logistics of loading and distributing the fuel among available shipboard tanks. [2] A person dealing in trade of bunker (fuel) is called a bunker trader. The term bunkering originated in the days of steamships, when coal was stored in ...
