Electronics which deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies.

An electronvolt is the amount of kinetic energy gained by a single electron accelerating from rest through an electric potential difference of one volt in vacuum.

A welding process that produces coalescence of metals with molten slag that melts the filler metal and the surface of the workpieces. The weld pool is shielded by this slag which moves along the full cross section of the joints as welding progresses.

An electrostatic generator, or electrostatic machine, is an electromechanical generator that produces static electricity, or electricity at high voltage and low continuous current.

Electrostatics is a branch of physics that studies electric charges at rest.

Electrowetting is the modification of the wetting properties of a surface (which is typically hydrophobic) with an applied electric field.

Vertical transportation facilities, passenger lifts, service/crew elevators.

An embankment dam is a large artificial dam.

Refers to any time that crew boards the ship, like initial boarding or boarding in a port of call.

The ladder provided at survival craft embarkation stations to permit access to survival craft after launching.

Embodied energy is the sum of all the energy required to produce any goods or services, considered as if that energy was incorporated or 'embodied' in the product itself.

Emergence occurs when an entity is observed to have properties its parts do not have on their own, properties or behaviors which emerge only when the parts interact in a wider whole.

A safety mechanism to arrest the cable in the event of a catastrophic failure or danger to personnel, when the cable must be stopped immediately.

A condition under which any services needed for normal operational and habitable conditions are not in working order due to failure of the main source of electrical power, (acc. to SOLAS, Chapter II-1, Part A).

Mandatory consumers, which after breakdown of the main energy supply, must be fed by the emergency energy supply.

Emergency core cooling systems are designed to safely shut down a nuclear reactor during accident conditions.

Emergency drive systems are typically installed in ships with geared medium-speed engines by connecting an electric motor to a pinion shaft in the gearbox (PTI) via a clutch. In normal use the motor serves as a power take-off (PTO) shaft generator.

GRP cabinets weathertight to IP55 with a range of equipment to aid escape from enclosed spaces in the vessel under unusual circumstances, for instance...

A self-contained compressed air apparatus for escape from a contaminated environment. It consists of a compressed air cylinder with air capacity of 600 litres (15 minutes duration).

A seawater pump which supply the ship fire main when the machinery space pump is not available.
