This project topic is proposed with Professor Mary Ann Lundteigen as main supervisor for fall 2015. I will use this wiki page in relation to the project execution, meaning that more details related to tasks to be carried out may be published here.
| Important information: I will hold an information meeting about the project Wednesday 13th of May at 12-13. Please notify me in advance if you are coming. If more than 8 students, I will need to find a new room to make a seat for all. |

About the project
This project assignment is based on the theory and methods you learnt in TPK 4120 Safety and Reliability Analysis and what you will learn in TPK5170 – RAMS assessment and optimization in the coming autumn. The intention is that several students may choose this assignment, supervision will be given jointly half of the semester then individually, and each student must submit individual project reports.
...
The supervision will be joint in the start of the semester, and individual as needed later in the semester. Each student must submit individual project reports on the topics agreed.
Project tasks
| Sub project | TasksPreliminary tasks | Useful literature |
|---|
Reliability and safety
assessments
of subsea systems | - 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 publicationsarticles, 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, with basis in a literature survey.
- Extend on elements of RAMS management, by studying:
- The RAMS management approach
Give a more thorough description of the RAMS management system - used in railway industry, with basis
50129, supplemented with
scientific publications, reports and industry guidelines.
- Identify RAMS activities in relation to critical road infrastructures, like tunnels and bridges
- 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 Make a comparison of the approach to RAMS management in railway and critical road infrastructures,
and 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
|
| Joint for both projects | I would like - towards the end of the semester (e.g., 3 weeks before handing in the project) - that you give a presentation of your work in a mini seminar arranged for this purpose. The main benefits of this approach are: - It is often helpful in the final stage of the work to extract the main findings and results, and share them with others for feedback
- It represents a milestone, and milestones are good to have at least towards the end
- You are able to also see what the others have been doing, and perhaps you get some ideas to bring into your own work
