Une grille partiellement obstru\u00e9e augmente la perte de charge au niveau de la prise, ce qui peut r\u00e9duire le d\u00e9bit d'eau de refroidissement et, \u00e0 terme, affecter la production de la centrale ou augmenter les co\u00fbts \u00e9nerg\u00e9tiques de pompage. Si la situation n'est pas corrig\u00e9e suffisamment longtemps, l'encrassement ou les d\u00e9gradations structurelles peuvent aussi cr\u00e9er les conditions d'un arr\u00eat impr\u00e9vu plus grave. Ces effets s'accumulant progressivement, un programme d'inspection subaquatique planifi\u00e9, plut\u00f4t qu'une action d\u00e9clench\u00e9e seulement par une baisse de performance mesurable, permet d'\u00e9viter que les pertes li\u00e9es \u00e0 la prise d'eau ne deviennent un poste r\u00e9current du budget de maintenance de la centrale.<\/p><p dir=\"ltr\">La documentation compte autant que le travail de plong\u00e9e lui-m\u00eame dans ce type de projet.

Un contractant qui documente chaque inspection de mani\u00e8re coh\u00e9rente, en utilisant toujours les m\u00eames points de r\u00e9f\u00e9rence et le m\u00eame syst\u00e8me de notation d'\u00e9tat, permet de suivre l'\u00e9tat de l'ouvrage sur plusieurs ann\u00e9es plut\u00f4t que de traiter chaque visite comme un \u00e9v\u00e9nement isol\u00e9.<\/p><p dir=\"ltr\">Les ing\u00e9nieurs de centrale \u00e9valuant un contractant de plong\u00e9e pour ce type de travaux devraient privil\u00e9gier une \u00e9quipe disposant d'une exp\u00e9rience document\u00e9e sp\u00e9cifiquement sur des sites industriels et \u00e9nerg\u00e9tiques, car travailler en s\u00e9curit\u00e9 sur une installation en exploitation exige des protocoles de coordination que les entreprises de plong\u00e9e commerciale g\u00e9n\u00e9rales ne poss\u00e8dent pas toujours.
