Governments have a duty under different conventions to issue the relevant certificates for their own flag vessels, although they may delegate their authority, and often do so, to the classification societies.
Statutory surveys are required to satisfy International Convention requirements such as Load Line, SOLAS, and MARPOL and are supplementary to Class requirements.
A term for bulwarks and hatch coaming brackets. Wires or ropes from the deck to the head of a mast, samson post or boom to provide support or prevent movement.
In systems theory, a system or a process is in a steady state if the variables (called state variables) which define the behavior of the system or the process are unchanging in time.
Steam is water in the gas phase.
A Steam engine is an external combustion engine that derives motion from the thermal expansion or condensation of steam.
An explosion caused by violent boiling or flashing of water or ice into steam, occurring when water or ice is either superheated, rapidly heated by fine hot debris produced within it, or heated by the interaction of molten metals (as in a fuel–coolant interaction of molten nuclear-reactor fuel rods with water in a nuclear reactor core following a core-meltdown).
Steam reforming or steam methane reforming is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water.
A steam trap is a device used to discharge condensates and non-condensable gases with a negligible consumption or loss of live steam.
A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft.
Steam turbine governing is the procedure of controlling the flow rate of steam to a steam turbine so as to maintain its speed of rotation as constant.
The is a power station in which the electric generator is steam driven.
Steel is an alloy of iron and carbon which is made of pig iron by removing the excess of carbon and the undesirable components by means of oxidation reactions.
A support structure for offshore wind turbines the similar to those used in the oil and gas industry, in water 20–80 metres (70–260 ft) deep
Material delivered to the shipyard contains mill scale and rust. Before fabrication, plates and profiles are blasted and primed at the automatic blasting and paint priming facilities.
Steel plates, coils, bars and other products. Stowage factors vary from 0.3 to 0.5 m3/t.
The method of supporting the weight of a hatch panel whilst correctly mainaining the design compression of the seal.
The machinery, rudder actuators, steering gear power units and the means of applying torque to the rudder stock necessary for eff ecting movements of the rudder.
According to SOLAS requirements, the steering gear compartment shall be readily accessible and, as far as practicable, separated from the machinery spaces.
The equipment through which orders are transmitted from the navigation bridge to the steering gear power units.
