Effectiveness of Gas Injection Suppression in Cabinets

AMOG was engaged to assess the effectiveness of gas injection suppression in cabinets by ASC Pty Ltd, who were responsible for the in-service support of the RAN Collins Class submarine.

Up until 2007, fire fighting procedures for extinguishing fires within electrical cabinets on the submarine required that the cabinets be opened, which could result in flare-up of a fire. ASC therefore intended to include gas injection sockets into the cabinets so that fires could be extinguished without opening the cabinet.

AMOG was tasked with determining whether these nozzles would be effective in controlling a fire, and if so, the best locations for these nozzles.

AMOG created CFD models of the cabinets, and assessed the performance of the gas injection suppression system for a number of different configurations. The most effective configuration was found and then further refined through additional modelling.

AMOG's analysis allowed ASC to remove a significant hazard from the Collins Class Submarine, and gave them confidence in the performance of their suppression system.

AMOG has also Conducted the System Safety Program for platform integration issues associated with the introduction of Mk 48 Advanced Capability to COLLINS Class Submarines and Submarine Training and Systems Centre Weapons Handling and Discharge Training Rig. AMOG developed safety deliverables in accordance with MIL-STD-882C including: SSPP, PHL, PHA, SRCA, SSHA, SHA, OSHA, HHA, TEHA, SCHR, and SV.
