SAM provides the ability to comprehensively validate the redundancy of complex systems to any type of scenario, including loss of multiple compartments.
Understanding of critical failures
The outcome of the analysis carried out with SAM includes information on the impact of failures on active components, subsystems and auxiliaries, including power generation and supply. It also provides options for recovering the systems, including manual actions by the crew. The system can greatly enhance the Failure Mode and Effect Analysis (FMEA) process.
Operability of systems can be achieved by systems segregation, redundancy and/or active recovery of affected components and sub-systems. The SAM environment allows the designer to assess systems design alternatives in a time-efficient manner; facilitating the identification of optimal ship systems concepts and arrangements: i.e. in line with statutory provisions and consistent with operational practice.
The outcome of the analysis is reported automatically and can be customised to facilitate design iterations or final verification. The results can be presented and analysed (i) system by system, (ii) by location and (iii) by type of damage. The level of detail of the results is suitable for use in FMEA studies.
The SAM model developed during the design process can be used to assess and monitor compliance throughout the lifecycle: during planned maintenance, during upgrades and conversion, etc.
Once an SAM model is available, the analysis can be easily expanded to assess systems operability and vulnerability in more representative casualty scenarios. This can greatly assist in the development of crew operating manuals, emergency contingency planning and crew training.
