Section 1 Terms, definitions and acronyms related to Part 2

1.1.1 The following terms and definitions are relevant:

• Concept of Operations Statement. (ConOpS) details the Owner’s vision of how the submarine is to be operated and maintained throughout the lifecycle of the submarine.
• Degraded state. Degradation. The physical condition of the submarine systems, equipment and components following an extended build period or period of in-service operation. Degradation can be from corrosion, exposure to chemicals, biological attack, material changes, creep, fatigue, erosion, wear. These may place restrictions on the Operational Envelope.
• Design constraint. Limitations imposed on design variables which result from decisions made during the design process. Imposed so that the design can be realised. These will be recorded in the Operational Envelope.
• Evidence. The results of documented activities undertaken by suitably qualified and experienced personnel from within the designer’s, builder’s, product manufacturer’s or maintenance organisation’s own organisation (second-party assurance) in order to demonstrate compliance withproject specifications, Rules, Codes and standards. Evidence includes:
  • Analysis. Demonstration of compliance with defined requirements using appropriate analytical techniques. The analytical techniques and the results thereof are to be reviewed by LR or suitably qualified and experienced persons from an independent organisation acceptable to LR.
  • Design audit. Demonstration of compliance with defined requirements for design assurance. The results of the audit are to be reviewed by LR or suitably qualified and experienced persons from an independent organisation acceptable to LR.
  • In-service experience. Demonstration of compliance with defined requirements using performance data acquired under representative operational conditions which include normal, abnormal and emergency operation. The performance data and associated operational conditions are to be reviewed by LR or suitably qualified and experienced persons from an independent organisation acceptable to LR.
  • Internal inspection. Demonstration of compliance with defined requirements through physical examination. The results of the inspection are to be reviewed by LR or suitably qualified and experienced persons from an independent organisation acceptable to LR.
  • Internal review. Demonstration of compliance with defined requirements through examination of the design. The results of the examination are to be reviewed by LR or suitably qualified and experienced persons from an independent organisation acceptable to LR.
  • Modelling and simulation. Demonstration of compliance with defined requirements through an agreed modelling or simulation programme. The modelling or simulation programme, the input data and the results thereof are to be approved by LR or suitably qualified and experienced persons from an independent organisation acceptable to LR.
  • Testing. Demonstration of compliance with defined requirements through an agreed schedule of testing. The test schedule and the results thereof are to be approved and witnessed by LR or suitably qualified and experienced persons from an independent organisation acceptable to LR.
  • Trials. Demonstration of the performance of the submarine or its systems, equipment and components against defined requirements through an agreed programme of trials under representative operating conditions. The trials programme and the results thereof are to be approved and witnessed by LR or suitably qualified and experienced persons from an independent organisation acceptable to LR.
• Project specifications. Engineering requirements to be imposed upon submarine systems, equipment and components. Contained within engineering specification or the submarine specifications rather than published Rules, Codes or Standards.
• Safety Criticality. A category assigned to a system, equipment or component through a formal process. The level assigned is based on the impact on the submarine or embarked persons for defined operating conditions. (See Vol 1, Pt 4, Ch 3, 2 System and equipment categories)
• Verification activities. Documented activities undertaken by LR or an independent organisation acceptable to LR (third-party assurance) in order to verify compliance with project specifications, Rules, Codes and standards. Verification activities include:
  • Design Appraisal. Verification of compliance with defined requirements through examination of the design by LR.
  • Design review. Verification of compliance with defined requirements through examination of the design by suitably qualified and experienced personnel from an independent organisation acceptable to LR.
  • Document review. Examination or audit of manufacturers records of production, measurement, testing and quality. Review is undertaken by LR.
  • Independent analysis. Verification of compliance with defined requirements using appropriate analytical techniques by LR or suitably qualified and experienced persons from an independent organisation acceptable to LR.
  • Independent inspection. Verification of compliance with defined requirements through physical examination by LR or suitably qualified and experienced personnel from an independent organisation acceptable to LR.
  • Monitoring. Verification of compliance with defined requirements through regular scheduled inspections of ongoing manufacturing activities by LR or suitably qualified and experienced personnel from an independent organisation acceptable to LR.
  • Patrol. Verification of compliance with defined requirements through unscheduled inspections of ongoing manufacturing activities by LR. The frequency and scope of patrol is determined from the results of verification activities.
  • Survey. Verification of compliance with defined requirements by LR using a combination of verification activities as appropriate.
  • Witness of testing. Verification of compliance with defined requirements through inspection of the physical testing performed by the manufacturer. Inspection is by LR or suitably qualified and experienced personnel from an independent organisation acceptable to LR. Production may be held until the verification activity is complete.
  • Witness of process event. Verification of compliance with defined requirements through inspection of a manufacturing activity or event, by LR or suitably qualified and experienced personnel from an independent organisation acceptable to LR. Production may be held until the verification activity is complete.
  • Works approval. Verification of a product manufacturer’s or builder’s quality assurance system, production processes and records together with testing of representative materials and processes and approval thereof by LR.
