Question 1

How does the depth of understanding this OCIMF DP FMEA Assurance Framework expects (common point management, configuration-scope testing, hidden failure detection, life-cycle review triggers) connect to MCA oral examination expectations for officers serving on DP-capable vessels, and to the existing IMCA-sourced DP FMEA content already in this content library?

Accepted Answer

This framework adds the OCIMF/charterer assurance angle (what an OVID inspector specifically checks for and why) on top of the existing IMCA-sourced engineering-standard content, and the same underlying reasoning — distinguishing coverage gaps from depth gaps, recognising hidden failures, understanding why untested configurations remain a real risk — is exactly the applied understanding both MCA examiners and OVID inspectors are testing for This module deliberately complements rather than duplicates the existing dp-fmea-trials-seed.php content (IMCA M252/M140-sourced, focused on the engineering-standard "what is an FMEA and who approves it") by adding the OCIMF assurance-framework angle — what a chartering oil major's OVID inspector is specifically looking for when assessing FMEA quality, which is a commercially distinct but substantively overlapping body of knowledge.

Question 2

OCIMF's DP FMEA Assurance Framework states it was developed because, despite extensive existing guidance, "a significant number of FMEAs lack comprehensive analysis," and that adherence to its prescribed format "will be confirmed by OVID inspectors as part of the DP FMEA assurance processes commissioned by OCIMF members." What does this tell a DP crew member about what an OVID inspection is actually checking when it comes to the FMEA?

Accepted Answer

The OVID inspector is not just confirming a class-approved FMEA document exists onboard, but assessing whether that document meets a specific quality and completeness standard (clear identification of common points, fail-safe conclusions, compensating provisions) — a vessel can hold a class-stamped FMEA and still fail this assurance check if the document itself is not comprehensive This is the critical, easily-missed point: OCIMF built this framework specifically because class approval alone was not catching FMEA quality gaps — the 2004 UK HSE/DNV review found weaknesses including non-thorough class review and late submission. An OVID inspection using this framework is checking the substance of the document, not just its existence or its class stamp.

Question 3

The framework defines a "common point" as an element that "interfaces with or influences redundant groups and... can defeat the redundancy concept," and states common points "cannot be eliminated completely in a redundant DP system" — closed bus ties, cross-connected control power supplies, and some hybrid power designs are cited as examples. Why does the framework treat common points as something to be managed rather than something a well-designed DP system simply avoids entirely?

Accepted Answer

Some common points exist because they are required to achieve specific legitimate design objectives (e.g. closed bus tie operation for certain power management benefits) — the framework's actual requirement is that any common point that does exist must be explicitly identified, its failure modes analysed, and its compensating provisions proven by testing, not that DP systems must have zero common points to be acceptable This is a precise, easily misunderstood point — the framework is not a zero-common-points standard, it is a "if a common point exists, prove you understand and have mitigated it" standard. A DPO or vetting-facing officer who assumes any common point automatically means a failed system, or conversely assumes common points are harmless because they sometimes serve a legitimate purpose, has both gotten the principle wrong in different directions.
