Fabrication

marine

Various processes of producting the structural ship parts.

Fabrication shop

marine

A shipyard facility where plates and profiles are cut and welded together. The assembly systems begin with plates and profiles being moved into a fabrication shop.

Fabrication tolerance

marine

A permissible deviation from a specified value, expressed in actual values or more often as a percentage of the nominal value.

Face plate

marine

Generally, a narrow stiffening along the inner edge of web frames, stringers, etc, to form the flange of the member.

Factor of safety

energy

In engineering, a factor of safety, also known as (and used interchangeably with) safety factor (SF), expresses how much stronger a system is than it needs to be for an intended load.

Factory

energy

A factory, manufacturing plant or a production plant is an industrial site, often a complex consisting of several buildings filled with machinery, where workers manufacture items or operate machines which process each item into another.

Fahrenheit

energy

The Fahrenheit scale is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit. It uses the degree Fahrenheit (°F) as the unit.

Fail-safe

energy

Fail-safe is a design feature or practice that in the event of a specific type of failure, inherently responds in a way that will cause minimal or no harm to other equipment, to the environment or to people.

Failure

energy

Failure is the state or condition of not meeting a desirable or intended objective, and may be viewed as the opposite of success.

Failure analysis

energy

Failure analysis is the process of collecting and analyzing data to determine the cause of a failure, often with the goal of determining corrective actions or liability.

Failure cause

energy

Failure causes are defects in design, process, quality, or part application, which are the underlying cause of a failure or which initiate a process which leads to failure.

Failure mode and effect analysis (FMEA)

marine

A failure analysis methodology used during design to postulate every failure mode and the corresponding effect or consequences. The analysis begins by selecting the lowest level of interest (part, circuit, or module level).

Failure mode and effects analysis

energy

Failure mode and effects analysis is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects.

Fairlead

marine

A guide for a mooring line which enables the line to be passed through a ship bulwark or other barrier, or to change direction through a congested area without snagging or fouling.

Fairway

marine

Navigable part of a waterway.

Fairway speed

marine

Mandatory speed in a fairway.

Fall

marine

The rope with blocks making up a tackle. The end secured to the block is called the standing part; the opposite end, the hauling part.

Fall preventer devices (FPD)

marine

Arrangements that provide a physical barrier to inadvertent on load hook release.

Fallpipe rockdumping vessel

marine

A very specialized ship consisting of a hold in which graded rock is stocked. The rock material is placed at an exact location on pipelines or the sea bottom through a fallpipe.

Falls

marine

Wires or ropes used to hoist or lower a boat or cargo.
