Heat content of the fuel with the heat of vaporization excluded. The water vapour is assumed to be in a gaseous state.

Traditional diesel-electric propulsion consists of several generating sets and drive syste ms, each consisting of a propulsion transformer, a frequency converter for speed control, an electric motor and a thruster.

Wärtsilä developed combustion process which reduces the NOx emission level in the diesel engine by up to 25-35% without compromising on thermal efficiency.

Low voltage ride through is the capability of electric generators to stay connected in short periods of lower electric network voltage.

A low-carbon economy is an economy based on low-carbon power sources that therefore has a minimal output of greenhouse gas (GHG) emissions into the atmosphere, specifically carbon dioxide.

Low-carbon power is electricity produced with substantially lower greenhouse gas emissions than conventional fossil fuel power generation.

Low-cost country sourcing is procurement strategy in which a company sources materials from countries with lower labour and production costs in order to cut operating expenses.

A building that makes use of any of a large number of techniques to lower energy use.

The concentration of a hydrocarbon gas in air below which there is insufficient amount of hydrocarbon to support and propagate combustion. Sometimes referred to as lower explosive limit (LEL).

LLW includes items that have become contaminated with radioactive material or have become radioactive through exposure to neutron radiation. The radioactivity can range from just above background levels found in nature to very highly radioactive in certain cases such as parts from inside the reactor vessel in a nuclear power plant.

In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations.

A low-voltage network or secondary network is a part of electric power distribution which carries electric energy from distribution transformers to electricity meters of end customers.

In a refrigeration cycle, the refrigerant circulates from the evaporator through the compressor to the condenser and back to the evaporator. In the evaporator, the heat added to the refrigerant by boiling off is taken from the surroundings.

A sea going vessel designed specifically for the transportation of LPG.

CELANOVA has been built for service around the southern Spanish coasts and the Balearic Islands.

Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces.

A high boiling point product of the crude oil refining process, used to lubricate machinery. Various properties required are obtained by blending and the introduction of additives such as oxidation inhibitors, dispersants and detergents.

Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces.

To raise or lower a derrick or a crane jib.

A ship used for the transportation of lumber (timber) and other wood products.
