Membrane pump on an oil tanker deck, to evacuate any leak down to the slops tanks. One of the firefighting pumps on the salvage tug Abeille Bourbon Electrical motors for ballast water pumps — on the oil tanker Algrave. A Marine pump is a pump which is used on board a vessel or an offshore platform.
A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs. The design also incorporates an intake to provide water to the pump and ...
A pump-jet, hydrojet, water jet, or jet drive uses a ducted propeller (axial-flow pump), centrifugal pump, or mixed flow pump to create a jet of water for propulsion. These incorporate an intake for source water and a nozzle to direct its flow out, generating momentum, and in most cases, employing thrust vectoring to steer the craft.
[8] [9] In 2023 DARPA launched the PUMP program to build a marine engine using superconducting magnets expected to reach a field strength of 20 Tesla. [10] Stronger technical limitations apply to air-breathing MHD propulsion (where ambient air is ionized) that is still limited to theoretical concepts and early experiments. [11] [12] [13]
Brons two-stroke V8 diesel engine driving a Heemaf generator. DeltaHawk DHK180 engine for aircraft propulsion burns Jet A & Jet A-1, JP5, JP8, Diesel (D1 and D2), JP-8-100, and F-24 fuels; Burmeister & Wain (part of MAN Diesel since 1980), double-acting diesels for marine propulsion from 1930 onwards, also made by shipbuilders under licence
The engine is the largest reciprocating engine in the world. The 14-cylinder version first entered commercial service in September 2006 aboard the Emma Mærsk. The design is similar to the older RTA96C engine, but with common rail technology (in place of traditional camshaft, chain gear, fuel pump and hydraulic actuator systems).
