• Make a description of the subsea system agreed upon
  • Functional description
  • Failure modes and failure classification
  (A possible case study is blowout preventer (BOP) due to the extensive amount of information available, or alternatively,
  the autonomous high integrity pressure protection system (HIPPS) that is often installed in relation to subsea tie-ins)
• Identify and discuss applicable reliability and safety challenges in relation to the operation of such systems
• Identify and describe relevant regulations and standards that apply for design and operation of this system
• Identify and discuss relevant measures in relation to safety and reliability assessments of the system
• Identify and compare methods used to assess reliability in literature for the system being considered
  and/or of systems that share key properties of this system, and discuss the pros and cons
  of the different approaches
  • (A selection on methods may be selected)
• Identify and discuss key parameters for reliability assessment, and the availability to data that may
  support such assessments
• Identify ideas for further work

The project tasks are carried out with basis in a thorough literature review that is documented in the report.

Relevant literature will depend on the application, and may include:

• Regulatory webpages and regulations (giving overall requirements, and references to applicable standards)
• Standards and industry guidelines, that give more detailed requirements on methods and practices
• Patents as a useful source of having detailed description of system elements
• Scientific articles, that include proposals for new methods or the results of case studies
• Books, such as https://www.ntnu.edu/ross/books/sis.

Management of RAMS in design
of critical (road) infrastructures

• Give a description of the E-39 Ferry Free project and identify and discuss some of the challenges faced that
  may be attributed to reliability, availability, maintainability/maintenance, and safety.
• Give a description of the typical lifecycle phases of a critical road infrastructure, with support of relevant
  handbooks published by the Road Administration ("Statens vegvesen")
• Define what we mean by RAMS management, and the typical activities involved.
• Extend on elements of RAMS management, by studying:
  • The RAMS management approach used in railway industry, with basis in in EN 50126 and
    scientific publications, reports and industry guidelines.
  • Technology qualification approach used in the oil and gas industry, with basis in DNV-GL
    recommended practice and API standards, supported by scientific literature, reports and
    industry guidelines on the area.
  • Lifecon project, an EU project carried out with focus on lifecycle management of concrete structures
• Compare differences and similarities in the RAMS management approaches that have been studied
• Point at some of the areas where improvements are needed.
  
   

Relevant literature include:

• EN 50126 (international standard for railway, accessible from NTNU library)
• Various reports on E-39 ferry free project (many of these are in Norwegian)
• Various handbooks published by the Road Administration (often in Norwegian)
• Previous EU project called Lifecon (link to be provided)
• Scientific articles on RAMS management
• Reports and guidelines on tunnel safety
