Subject field(s)
  • Transport of Water (Water Supply)
DEF

... a pipeline conveying water by gravity from a source of supply in a stream or body of water to an intake well.

CONT

An important place within water supply systems is represented by the adduction pipes. The flow in adductions can be characterized by free level under the pressure, or in certain situations in a mixed manner. The modification of design parameters and of the hydrodynamic regime in the adductions for water is developed in a continuous destructive process or variable in time. The multiple actions determine the modification of the constructive and functional parameters of the adduction, diminish the mechanic resistances, disturb the stability and decrease the safety in the construction exploitation.

La certification de gréeur exige de la part de tous les candidats une implication évidente pour maintenir son expertise tout en restant à jour. Pour se maintenir à jour le gréeur devrait avoir effectué des activités de gréage de parachute pendant au moins trente jours dans les 12 derniers mois, à n'importe quel moment, ou en démontrant au CT&S [Comité de technique et sécurité] sa capacité d'accomplir des tâches reliées au gréage.

Record 42 1995-11-22

English

Subject field(s)
  • Engineering Tests and Reliability
DEF

Risk of the EUC and its control system (providing it is not a designated safety-related system) and associated human factor issues.

OBS

The main purpose of determining the EUC risk is to establish a reference point for the risk without taking into account safety-related systems and external risk reduction facilities.

Record 43 1995-11-22

English

Subject field(s)
  • Engineering Tests and Reliability
DEF

A protection system designed to respond to conditions on the EUC, which may be hazardous in themselves, or if no action were taken, could give rise to hazardous events, and to generate the correct outputs to mitigate the hazardous consequences or prevent the hazardous events.

OBS

In many cases the correct response of the protection system would be to bring all processes or movements to a predetermined safe state; in others the correct response may be more complex e.g. involving an ordered shutdown or start-up of equipment. The correct response may depend on the state of the EUC.
