10 System Integrity Certification & Test Procedures


10.1 Objective


The objective of this Chapter is to outline the certification and test procedures required for the situational awareness, control and other mission-critical systems within a MASS.


10.2 Scope


10.2.1 Verification shall be undertaken to provide assurance that the Situational Awareness and Control System complies with the provisions of this Code and remains compliant throughout its life.


10.2.2 The Risk Assessment for the MASS shall be reviewed in detail, to check that no critical single point failures have been overlooked. The Risk Assessment shall be confirmed as being thorough and conservative in its safety assessment.


10.3 System test based on Risk Assessment


10.3.1 All safety critical items covered by failure sensing and remedial action, or by dual or multiple redundancy, having been highlighted in the Risk Assessment, shall be individually tested by simulating each failure mode of each sub-system or component and verifying that the backup measures are effective in mitigating any critical consequences.


10.3.2 The effects of power failures shall be checked, to ensure that simultaneous power failures on several sub-systems do not invalidate critical safety measures that rely on dual redundant systems.


10.3.3 System integrity testing shall be performed in a hierarchical manner in such a way as to ensure that each sub- module functions in accordance with performance requirements. Integration testing shall be performed to test the interfaces and the performance of the combined systems.


10.3.4 Electronic systems shall be installed in the same manner as for manned vessels. This includes EMC compliance, use of enclosures and connectors with suitable marine grade IP ratings, communications standards EIA-422, EIA-232, NMEA 0183 and NMEA 2000 and others as appropriate.


10.3.5 Simulators may be used to verify levels of performance of some but not all systems. This includes autopilot performance, collision avoidance algorithms, though not the systems whose performance is critically dependent on real-world stimuli, such as optical and inertial sensors.
