BC Code

marine

see Code of safe practice for solid bulk cargo (BC Code).

Bcf

marine

Billion cubic feet, a unit measurement for large volumes of gas. 1 Bcf is approximately 28.32 million m3.

Beacon

marine

A conspicuous mark used as a guide to mariners, either a landmark, erected on an eminence near the shore, or a mark moored or driven into the bottom in shallow water.

Beam

marine

1. A prismatic section with one dimension significantly larger than the others, that is subjected to bending loads.

Beam engine

energy

A beam engine is a type of steam engine where a pivoted overhead beam is used to apply the force from a vertical piston to a vertical connecting rod.

Bearing

marine

A common item in any mechanical system where two parts move relative to one another. A bearing enables the transfer of forces with a minimum of frictional losses.

Bearing pads

marine

Support pads installed on the hatch coaming in order to transfer the weight of the cover, and any cargo it may be carrying, to the ship hull while allowing for relative movement between the cover and the hatch coaming.

Beaufort scale

energy

A scale of wind forces, described by name and range of velocity, and classified from force 0 to 12.

Becquerel

energy

The becquerel is the SI derived unit of radioactivity. One becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second.

Bedplate

marine

A structure which forms the base of an engine upon which the bearings and frame are mounted.

Before breaking bulk

marine

An expression which actually means “before starting discharging of cargo”.

Bell

marine

A bell used aboard ship as a means of announcing time at regular intervals, as a signal when the ship is anchored in a fog, or as an alarm in emergencies.

Bell crank

marine

A hydraulically-operated mechanism which folds the second pair of covers in a four-panel folding hatch cover.

Bellows

energy

In gauges intended to sense small pressures or pressure differences, or require that an absolute pressure be measured, the gear train and needle may be driven by an enclosed and sealed bellows chamber, called an aneroid, which means "without liquid".

Bellows unit, bellows expansion joint

marine

Bellows-type expansion piece which is fitted into a pipeline to allow expansion and contraction resulting from temperature changes.

Belt unloading system

marine

The discharge system used on self-unloading bulk carriers.

Belt-type self-discharging bulk carrier

marine

Bulk carrier equipped with a belt unloading system.

Benchmarking

energy

Benchmarking is the practice of comparing business processes and performance metrics to industry bests and best practices from other companies.

Bend

energy

A fitting either molded separately or formed from pipe for the purpose of accommodating a directional change.
