Various processes of producting the structural ship parts.

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.

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

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

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.

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.

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

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 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.

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 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.

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.

Navigable part of a waterway.

Mandatory speed in a fairway.

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.

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

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.

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