Knowra Marine engineering Marine engineering Marine engineering applies engineering principles to the design, construction, operation, and maintenance of ships and systems that function in marine environments.
Marine propulsion : The systems that generate and transmit thrust to move vessels through water. Propulsion is a central engineering system aboard powered ships.
Diesel engine : An internal-combustion engine that ignites fuel by compressing air until it becomes hot. Diesel engines provide propulsion or electrical power on many ships.
Merchant ship : A commercial vessel that transports cargo or passengers by sea. Its propulsion, cargo, and auxiliary systems are common marine-engineering applications.
Naval architecture : The discipline of designing ships and other floating structures, including their form, stability, and performance. It focuses more on vessel form and behavior, while marine engineering emphasizes machinery and systems.
Ship stability : A vessel’s ability to return toward an upright equilibrium after being disturbed. Machinery placement and loading affect a vessel’s stability and safety.
Marine gearbox : A transmission that adjusts engine speed and torque and may connect an engine to a propeller shaft. It transfers engine output to the propeller at suitable rotational speed.
Submarine : A watercraft designed to operate underwater, often for military or research purposes. Submarines require specialized propulsion, life-support, pressure, and control systems.
Ocean engineering : The engineering of structures and systems designed to operate in oceans and coastal waters. It covers a broader range of marine infrastructure beyond shipboard engineering.
Marine hydrodynamics : The study of water flow and forces around vessels and marine structures. Hydrodynamic forces shape propulsion demands, resistance, and system design.
Propeller : A rotating device whose blades produce thrust by accelerating fluid. It converts shaft power into thrust that drives a vessel through water.
