Placing the cooling radiator section in seawater rather than ambient air allows for the radiator to be smaller. The engine's cooling water may be used directly or indirectly for heating and cooling purposes of the ship. The Stirling engine has potential for surface-ship propulsion, as the engine's larger physical size is less of a concern.
The research intended to produce a concept tanker-ship design, based on a 70 MWt reactor such as Hyperion's. In response to its members' interest in nuclear propulsion, Lloyd's Register has also re-written its 'rules' for nuclear ships, which concern the integration of a reactor certified by a land-based regulator with the rest of the ship.
The monohull forward was designed to split swells and improve ride in heavy seas. Two turbosails rose from her deck and two diesel engines provided the necessary suction forces. The ship was named Alcyone, the daughter of the wind. When the Alcyone was launched in 1985, it benefited from the development of the original turbosail Moulin a Vent ...
Yggdrasil (from Old Norse Yggdrasill) is an immense and central sacred tree in Norse cosmology. Around it exists all else, including the Nine Worlds. Yggdrasil is attested in the Poetic Edda compiled in the 13th century from earlier traditional sources, and in the Prose Edda compiled in the 13th century by Snorri Sturluson.
For urgent orders requiring rapid acceleration, the handle is moved three times so that the engine room bell is rung three times. This is called a "cavitate bell" because the rapid acceleration of the ship's propeller will cause the water around it to cavitate, causing a lot of noise and wear on the propellers. Such noise is undesirable during ...
Screw-driven steamships generally carry the ship prefix "SS" before their names, meaning 'Steam Ship' (or 'Screw Steamer' i.e. 'screw-driven steamship', or 'Screw Schooner' during the 1870s and 1880s, when sail was also carried), paddle steamers usually carry the prefix "PS" and steamships powered by steam turbine may be prefixed "TS" (turbine ship).
Oregon, a ship in the Oregon Files series of books by author Clive Cussler, has a magnetohydrodynamic drive. This allows the ship to turn very sharply and brake instantly, instead of gliding for a few miles. In Valhalla Rising, Clive Cussler writes the same drive into the powering of Captain Nemo's Nautilus.
A powership (or power ship) is a special purpose ship, on which a power plant is installed to serve as a power generation resource. Converted from existing ships, powerships are self-propelled, ready to go infrastructure for developing countries that plug into national grids where required. [ 1 ]
