Plant minimum load (%)

energy

Lowest unit or plant level load that can be maintained for extended periods of time.

Plant output (MW)

energy

Typical size of the power plant.

Plant ramp rate (%/min)

energy

Percentage of the total load that the plant can increase in a minute (with an already running engine) to provide ancillary services.

Plasma

energy

Like a gas, plasma does not have definite shape or volume.

Plasma gasification

energy

Plasma gasification is an extreme thermal process using plasma which converts organic matter into a syngas (synthesis gas) which is primarily made up of hydrogen and carbon monoxide.

Plasma gasifier

energy

In a plasma gasifier a high-voltage current is fed to a torch, creating a high-temperature arc.

Plasma-arc cutting

marine

A process used primarily for the cutting out of steel components from plate in the workshop.

Plasmon

energy

A plasmon is a quantum of plasma oscillation.

Plasmonic enhanced solar cell

energy

A plasmonic-enhanced solar cell is a type of solar cell that converts light into electricity with the assistance of plasmons, but where the photovoltaic effect occurs in another material.

Plastic

marine

A solid material which contains one or more synthetic organic high polymers as essential ingredients.

Plasticity

marine

The property of a material that allows it to be extensively and repeatedly deformed without rupture and that allows it to retain its deformed shape after the applied force has been removed.

Plate fin heat exchanger

energy

A plate-fin heat exchanger is a type of heat exchanger design that uses plates and finned chambers to transfer heat between fluids.

Plate heat exchanger

energy

A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids.

Plate tectonics

energy

Plate tectonics is a scientific theory describing the large-scale motion of the plates making up the Earth's lithosphere since tectonic processes began on Earth between 3.3 and 3.5 billion years ago.

Platform supply vessel VIKING ENERGY

marine

The VIKING ENERGY is the world first LNG-fuelled PSV. The construction of the hull and superstructure was subcontracted to the Polish shipyard Maritim in Gdańsk from where it was towed to Kleven Verft in Ulsteinvik, Norway, for outfitting.

Plating

marine

The plates of a hull, a deck, a bulkhead, etc.

Plough

marine

A cable plough is a sophisticated seabed tool that creates and back fills trenchers in order to protect all types of submarine cable.

Plug

marine

A thing used for connecting a piece of electrical equipment to the main supply of electricity.

Plutonium Management and Disposition Agreement

energy

The agreement regulates the conversion of non-essential plutonium into mixed oxide (MOX) fuel used to produce electricity.

Plutonium-238

energy

Plutonium-238 (238Pu) is a radioactive isotope of plutonium that has a half-life of 87.7 years. Plutonium-238 is a very powerful alpha emitter; as alpha particles are easily blocked, this makes the plutonium-238 isotope suitable for usage in radioisotope thermoelectric generators (RTGs) and radioisotope heater units.
