Submarine Ventilation Systems
SEVDS
The submarine ventilation system has been operated by at least 50 (fifty) staff members who have experienced accidents at depths of up to 600 (six hundred meters) is an external ventilation system that will meet the air requirement for at least 14 (fourteen) days for a submarine that is expected to require at least 1.19 atmospheres of air per cubic meter of air. The Submarine Ventilation System is suitable for connecting to submarine adapter units with fittings in the NATO STANAG 1450 standard. Since the hoses exhausting from the submarine are 900 (nine hundred) meters long, pressure losses are experienced at the air outlet, and the air thus injected raises the pressure in the inner atmosphere of the submarine. According to the ATP-57 (B)? Submarine Search and Rescue Manual published by NATO, if the submarine's internal pressure exceeds 1.7 bar (a), victims are at risk of developing decompression sickness. As stated in ATP-57 (B), in order to keep the internal pressure of the submarine below 1.7 bar (a), the SEVDS system uses vacuum pumps and vacuums (external pressure resistant) hoses to aid in air evacuation. Signature and exhaust hose extensions of the submarine ventilation system, Dz.K.K. Submarine Adapter
Unit (SAU), which is in the inventory and has a connection element conforming to NATO STANAG 1450, is finalized. With these adapters at the ends of the Imla and Exhaust hose extensions, according to the depth of the submarine, the diver can carry and connect with ADS or ROV operation. The Submarine Emergency Ventilation and Decompression (SEVDS) control system consists of local and remote modules that control and monitor the components of the submarine ventilation system.
The primary objective of the SEVDS Control System is to ensure that the Oxygen level, Carbon Dioxide level, and pressure in a DISSUB are controlled while flushing other toxic gases out of DISSUB to a level that maintains life. This is accomplished by supplying breathing air to and removing exhaust air from the DISSUB. The breathing air will be supplied by the Pressurization System on the ship (MOSHIP). On deployment of the SEVDS, the DISSUB atmosphere will be monitored. From this initial monitoring, a breathing air supply rate, gas exhaust rate, and decompression rate are determined. The SEVDS Control System will be set up to provide and monitor these rates as well as monitor DISSUB conditions.
