One of the things that seems unusual is that whilst approximately 10% of classed vessels have their planned maintenance systems recognised by their classification society. This allows the Chief Engineer to credit a number of items for survey at some convenient time, only about 10% of these use approved condition monitoring process which the Chief can use to avoid opening these assets purely for the purposes of satisfying the regulatory requirement.
What that means is that only 1% of ships use condition monitoring for the purposes of classification. It is suspected that a significant number of vessels successfully employ some form of condition monitoring on a regular basis and may even use condition as a foundation for their maintenance strategy but do not take up the opportunity to align these processes with their classification society and therefore must be performing unnecessary invasive surveys and in doing so increasing the risk to reliability.
Why is this?
