Distilled water supplied to a boiler, usually by high-pressure pump (feed pump), to compensate for water lost by vapourisation. It is usually treated to remove air and impurities.
A tank for holding water that is used by a boiler to create steam.
The process of adding various chemicals to the feed water system and then testing samples of boiler water with a test kit.
Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop.
In the case of linear feedback systems, a control loop including sensors, control algorithms, and actuators is arranged in an attempt to regulate a variable at a setpoint.
Cargo to/from regional ports is transferred to/from a central hub port for a long-haul ocean voyage.
A feed-in tariff is a policy mechanism designed to accelerate investment in renewable energy technologies by offering long-term contracts to renewable energy producers.
A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system.
A thin metal strip of a particular thickness, with the value marked upon it. It is used for the precise measurement of gaps.
Femto (symbol f) is a unit prefix in the metric system denoting a factor of 10−15.
A resilient device built into (permanent fender) or hung over the sides to prevent the shell plating from rubbing or chafing against other ships or piers.
A fermion is a particle that follows Fermi–Dirac statistics and generally has half odd integer spin: spin 1/2, spin 3/2, etc.
The term “ferry” originally described a vessel carrying passengers or cargo on short trips across rivers or harbours or coastwise to inland.
Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets.
Fertile material is a material that, although not itself fissionable by thermal neutrons, can be converted into a fissile material by neutron absorption and subsequent nuclei conversions.
A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable, but containing one or more optical fibers that are used to carry light.
Fibre-reinforced plastic (FRP) (also called fiber-reinforced polymer, or fiber-reinforced plastic) is a composite material made of a polymer matrix reinforced with fibres.
Mutli-purpose crane and pipe laying ship SAIBOS is a dynamically positioned vessel designed to meet the requirements of deepwater field development work.
Angular size of the scene that can be observed from a position on the ship's bridge.
After sale service supplied to clients where engineers or technicians attend client sites, for example, to complete maintenance or repair activities.
