Failure Modes Effects and Criticality Analysis (FMECA)

The FMECA of any system shall assess the effects on different failure modes on that systems operating equipment and where required the support vessel interfaces. The resultant quantification may highlight deficiencies in design, lack of redundancy and failure to maintain the recommended critical spares to ensure safe and efficient operations, with the emphasis being on personnel safety.

A FMECA shall consider the failure of electrical, mechanical and control systems hardware as well as all supporting documentation and should identify any Codes of Practice that should be followed during the assessment, such as International Codes and Legislation, Class Society Rules, Industry Standards and any Company Management Systems.

The failure modes of typical systems and sub-systems of any system should be considered as well as any mitigation that is in place and should subsequently provide a criticality rating for each failure. This will provide critical information required to plan any additional mitigation that may need to be included within the system to ensure safe and efficient operations.

The failures are ranked for criticality based on the probability and severity of the failure and will highlight deficiencies in the system as well as identify mitigation currently in place or required to provide safer systems. The level of criticality will be identified pre and post mitigation which will have to be considered to ensure the failure mode criticality level is acceptable to commence operations.

Namaka Subsea will provide a team of competent multi-disciplined FMECA practitioners who will each add to the process their own expertise in operations and systems. Each team member is subject to our in-house competence scheme to confirm they have the required knowledge and experience to carry out their duties as part of the assessment.
