Abstract

Le procédé a trait à un nouveau système de sécurité permettant d'éviter les risques d'étincelles pendant les opérations de chargement ou déchargement de navires (ou équivalents). Après avoir effectué une liaison équipotentielle par câble entre le navire et l'appontement, on injecte dans le câble un courant de basse frequence (par exemple 1 000 hertz) et de faible puissance (par exemple 5 watts) et l'on détecte en permanence le passage de ce courant dans le câble côté navire et côté appontement en mesurant les éventuelles différences de niveau en intensité du courant détecté. Toute mauvaise connexion de mise à la terre des dispositifs de transfert (bras de chargement, pompes, etc.) est décelée et affichée par alerte sonore et/ou lumineuse.
