A loss of power to end users and communities also known as a power outage and usually a result of a system component failure.
Blade element momentum theory is a theory that combines both blade element theory and momentum theory.
Horizontal movement of a wind turbine blade at the tip while rotating.
A sound signal made with the whistle of the vessel. - Prolonged blast – A blast lasting four up to six seconds. - Short blast – A blast lasting about one second.
see Surface preparation grades.
The cleaning of a metal surface by a stream of abrasive particles (blasting agents). See also Abrasive blasting.
Copper works slag (MCU), fused corundum (MKE) as well as iron or steel blasting agents can be considered. The use of silica sand (MQS) shall be avoided.
The method of electrolytic descaling developed by Wilson Taylor. The method consists of current distribution points (CDP), which are hung inside the area to be cleaned.
A small cock, valve, or plug to drain off small quantities of fluids from a container or a system.
Heavy fuel and distillate fuels mixed in various proportions, usually 70:30.
Areas that cannot be scanned by the radar of the vessel because they are shielded by elements of its superstructure, masts, etc.
A raised area, often dome shaped, resulting from loss of adhesion between a coating or deposit and the substrate.
The formation of blisters in a paint film by localised loss of adhesion and lifting of the film. Blisters may contain liquid, vapour or gas.
Defined to be the sum of the zone loads.
Bulk carrier loading arrangement with two consecutive holds loaded and a subsequent one empty.
A blocked rotor test is conducted on an induction motor.
Opening blow-down cocks at the bottom of the boiler to reduce the amount of dissolved solids in the boiler water.
A blowdown stack is an elevated vent or vertical stack that is used to vent the pressure of components of a chemical, refinery or other plant if there is a process problem or emergency.
A machine that delivers air at the discharge pressure up to 40 pig. Blowers are used to supply relatively large quantities of low-pressure air to various destinations throughout the vessel.
A blowout is the uncontrolled release of crude oil and/or natural gas from an oil well or gas well after pressure control systems have failed.
