AMGC, a company specialising in equipment for vessel decks, delivered a water-tight door to the French department of naval construction (DCNS) for the Charles-de-Gaulle aircraft carrier.
The DCNS is a major fleet management institution which relies on an especially strict quality management system whose efficiency has been proven. In fact, this door has given rise to 42 acceptance reports: each component was thoroughly inspected, even the tiniest bolt.
The leaktightness of the door was one of the customer's essential requirements. "We work with Cetim on a regular basis, points out Allan Reymonenq, general manager of AMGC. Cetim makes clear and high-quality offers and only Cetim's experts managed to reply promptly to our request."
Checks carried out under real conditions
Cetim therefore carried out leaktightness tests at 100 mbar covering overpressure and vacuum pressure. The tests took place on a stand which simulates the location of the door with a mechanical locking system for the door, in order to be as close to actual operating conditions as possible. The door closes on a chamber in which overpressures are produced by regulating compressed air to 100 mbar or depressurisation to -100 mbar with a high-capacity vacuum pump.
The pressure changes were monitored and recorded in real time for one hour in both cases with one goal: not to lose overpressure or increase vacuum pressure by more than 3 mbar every ten minutes.
The target was reached: AMGC's door is now installed on the Charles-de-Gaulle aircraft carrier, ready for good and faithful service.
