A hybrid vessel equipped with hatch covers and cargo access facilities characteristic for ro-ro vessels.
The cargo handling system developed in Finland. It is focused on a 60-tonne capacity flat panel (12.2m x 2.6m) for loading cargo which is supported by four “legs” 850mm from the ground.
A rooftop photovoltaic power station, or rooftop PV system, is a photovoltaic (PV) system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure.
NILS HOLGERSSON and PETER PAN are 34,000gt RoPax ferries built by the Bremerhaven yard SSW Fahr-und Spezialschiffbau for Hamburg-based operator TT-Line.
A vessel with large ro-ro decks and limited passenger facilities. Usually, the superstructure covers part of the upper deck.
A two-part rope guard with ample overlap on the propeller hub protects the sterntube aft seal against mechanical damage in the event of a rope fouling the propeller.
Abbreviation for a vessel designed to carry vehicles, so arranged that the vehicles may be loaded and unloaded by being rolled on or off on their own and/or auxiliary wheels, via ramps fitted in the sides, bow or stern of the vessel.
An equipment fitted on ro-ro vessels to ensure access and movement of vehicles on board. A typical cargo system consists of a stern ramp/door, internal ramps or elevators and flood control doors.
Trailer trestles, support jacks, speedlash, wheel chocks.
Spaces not normally subdivided in any way and extending to either a substantial length or the entire length of the ship in which goods can be loaded and unloaded normally in a horizontal direction.

A rotary converter is a type of electrical machine which acts as a mechanical rectifier, inverter or frequency converter.
An internal combustion engine, usually designed with an odd number of cylinders per row in a radial configuration, in which the crankshaft remained stationary in operation, with the entire crankcase and its attached cylinders rotating around it as a unit.
Pumps that move fluid using a rotating mechanism that creates a vacuum that captures and draws in the liquid.
A positive displacement pump. For each revolution of the pump, a fixed volume of fluid is moved regardless of the resistance against which the pump is pushing.
A large casting located centrally within the drill floor used to impart rotary motion to the drill string, being chain driven from the draw-works.
A rotary table is a mechanical device on a drilling rig that provides clockwise (as viewed from above) rotational force to the drill string to facilitate the process of drilling a borehole.
