Section 6 Design for inspection and in-service verification

Parent topic: Chapter 3 Requirements for Systems

6.1 Functional objective

6.1.1 The submarine, systems, equipment and components shall be designed to enable safe and effective monitoring and inspection for in-service verification for all foreseeable operating conditions, where inspection is required to maintain operation.

6.2 Performance requirements

6.2.1 The submarine, systems, equipment and components shall be designed so that they are able to be:

  1. Monitored for key parameters;
  2. Isolated and deenergised for inspection, maintenance or replacement;
  3. Accessed for inspection of the material state;
  4. Accessed for maintenance or replacement; and
  5. Examined and tested to validate integrity and performance.

6.2.2 Examination, testing and inspection are to be possible without:

  1. Creating a hazard; and
  2. Requiring system modification.

6.2.3 Systems, equipment, and components test procedures are to be designed to eliminate the risk of maloperation during testing and inspection and return to normal use, e.g. accidental over pressurisation.

6.2.4 Systems should be designed so that they degrade gradually to enable deterioration to be detected with sufficient time before failure.

6.2.5 Systems, equipment or components which are not able to be inspected during the life of the submarine are to be provided with an engineering justification considering criticality, rates of degradation, redundancy and remote monitoring.

6.2.6 Survey, inspection and maintenance periods are to be defined. Intended inspection plan and maintenance routines are to be defined. Component life is to be determined and provided to the Navy.

6.2.7 Survey, inspection and test requirements shall be provided which defines the monitoring, access, inspection, and testing requirements.
