In physics, the restoring force is a force which acts to bring a body to its equilibrium position.
A deck, space, area, etc., not permitted to be entered for safety reasons.
Any condition in which visibility is restricted by fog, mist, falling snow, heavy rainstorms, sandstorms or any other similar causes, (COLREG).
Retarded start of injection is a commonly used primary method for effective NOx emission reduction in the diesel engines and has negligible effect on fuel consumption when keeping injection duration conveniently short.
The addition of new technology or features to older systems.
A ratio that describes the profitability or efficiency of an investment.
Reverse costing describes the process of disassembling (reverse engineering) a device to identify manufacturing technology and calculate its manufacturing costs through a cost analysis of its parts and the effort required to assemble them.
A relay fitted between a generator and the switchboard which will trip and disconnect the main circuit breaker in the event of a reverse current flow.
Reverse engineering is a process or method through the application of which one attempts to understand through deductive reasoning how a device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so.
In thermodynamics, a reversible process is a process whose direction can be reversed to return the system to its original state by inducing infinitesimal changes to some property of the system's surroundings.
The number of turns in one minute.
The Reynolds number (Re) helps predict flow patterns in different fluid flow situations.
A stabiliser system designed to reduce the craft wave-induced motions. Fast ferries operating in rough water require ride control systems to ensure passenger comfort.
The movement of an oil rig, drilling platform, etc., from one position to another.
Ropes, wire ropes, lashings, masts, booms, etc.
When the ship floating at rest in still water is inclined by an external force to a small angle fi, the centre of gravity G will remain in the same position but the centre of buoyancy moves towards the submerged side.
A solid body in which deformation is zero or so small it can be neglected.
Built at the Merwede Shipyard in Netherlands, the SEVEN OCEANS is intended for installation of rigid pipes up to a diameter of 16’’ on the ocean floor in depths up to 3000m using the reel-lay method.
A new type of drive developed by General Dynamics Electric Boat of Groton, USA. This drive is more compact and has several features that differ significantly from other pods available today.
In electricity supply design, a ring final circuit or ring circuit is an electrical wiring technique developed and primarily used in the United Kingdom, and to a lesser extent in Ireland and Hong Kong.
