The primary intent of the study is to demonstrate equipment selection, redundancies and sparing support as per the Company’s specified uptime goal. Any aspects of the Client’s design which would prevent the uptime specification being achieved will be clearly identified and options for improvement will be suggested.
Scope Of Work
The scope of the Reliability, Availability and Maintainability (RAM) Study are as follows:
- Calculate the availability of the facility;
- Rank the systems that are major contributors to the overall unavailability of the facility;
- Identify the critical equipment on the facilities;
- Assess the estimated availability of the facility against targeted availability requirements; and
- Propose effective means to improve the facility’s availability to meet the specified requirement.
The RAM study shall be performed in accordance to internationally accepted and Company standards. Upon study award, we will prepare a Study Basis for all assumptions to be used in the study. The proposed Study Basis will be submitted to the Client for approval prior to actual commencement of work.
The study shall be carried out using the life-cycle simulator software MAROS or equivalent.
Generic reliability, availability and maintainability data from OREDA shall be applied unless the Client can provide vendor-supplied data. The latest and most complete sources of data shall be used.
The Report (Draft and Final) shall include but not limited to the following:
- Overall system assumptions, outlining the assumptions of the study;
- Equipment modeling assumptions, describing the equipment configuration to be modeled along with specific details and assumptions that will be adopted during model development;
- Maintenance and operations assumptions, describing the maintenance and operations strategy for the facility;
- Reliability block diagrams, outlining the failure logic relationships between equipment and systems;
- Results from the RAM study, including the following:
- The annual and overall through-life average production efficiency over the field life; and
- The key contributors to production efficiency losses and their relative contributions to the overall performance.
