Reliability & Integrity Assurance

Astrimar consultants have been directly involved in the creation of industry practices such as API RP 17N for subsea systems. These recommend the setting of goals, requirements, plans and the provision of risk and reliability assurances on reliability and integrity critical equipment and new (or enhanced) technology. Astrimar uses the Define-Plan-Implement-Evaluate-Feedback cycle as a basis for reliability, integrity or technology assurance for projects and operations.

New technology developments often involve complex, socio-technical systems, requiring the integration of data and services from a variety of sources, developed and delivered by diverse teams of designers, engineers, operators and managers. The management and assurance of reliability, integrity and qualification is often a significant challenge for the development, project or operations team. At the same time, reliability and integrity assurances need to be clearly communicated to stakeholders to give the best possible indication that the system will work.

Astrimar supports clients implementing the API RP 17N Assurance Cycle:

  • Defining goals and requirements
  • Creating consistent plans to achieve them
  • Implementing activities in accordance with the plans
  • Evaluating the results against requirements
  • Providing feedback and assurance of achievements

Evidence of assurance may be provided in a variety of forms, for example field and factory test data, qualification tests, reliability analyses, inspection and monitoring data. Demonstration of close out of actions arising from analysis and testing or implementation of lessons learned is also valuable evidence.

Astrimar consultants can support the categorisation of evidence to ensure that there is a sufficient level of confidence in the assurance data; factors such as data sources, number of replicates, test environment and duration, model validation are reviewed to identify the degree of uncertainty in the evidence provided.

In addition, as an independent organisation, Astrimar can provide third party review, verification and audit of risk and reliability management practices and their deliverables.  Astrimar's consultants have developed a Reliability Capability Maturity Model (RCMM) for auditing the capability of equipment vendors and contractors to undertake reliability engineering in projects and deliver reliable products and services.  A key objective in carrying out these audits is to prevent the audit from becoming a negative judgmental experience for the company being audited.  Instead, our approach is always to look for opportunities to provide positive feedback, with recommendations to support continuous improvement of the company in delivery of reliable products and services.

Audits can be undertaken:

  • Prior to projects, to determine expected capability as an input to tender assessments and/or
  • During projects to verify reliability process achievements.

The different types of reliability capability assessments provided by Astrimar are:

  • Detailed RCMM evaluation
  • High-level review
  • Review of project specific application
