CM Specialist – BUYER BEWARE!

In the field of condition monitoring there are a number of specialist technologies such as Vibration analysis; Lube oil testing; Thermography; Acoustic emission; Electrical signature analysis where competence can be assessed under an agreed standard.

Shipping companies engage directly or via contractual arrangements individuals to provide CM support, diagnostics and prognostic advice as part of their planned preventative or condition based maintenance strategy.

The problem for the shipping company is that it is completely acceptable for an individual to claim that he or she is certified at Category I through IV in standards such as the ISO 18436 suite of standards, furthermore it is acceptable for that to be based upon a first party self assessment basis.

It is also acceptable to become certified to this standard within a company scheme, a second party approach.

Both of these methods of demonstrating compliance are considered unacceptable by professional CBM practitioners as this undermines those who seek to differentiate based upon clearly verified competence.

It is therefore is strongly recommended to cite third party independently certified persons within tenders and commercial contracts as this demonstrates a sufficient depth of control to ensure that both the individual and the certifier have been thoroughly examined and can demonstrate competence and compliance.

Ask to check and demand it!


Condition-based maintenance – the role of the classification society and the challenges faced by the ship manager
Tuesday 13 March, 2012

The session was a useful event with great presentations highlighting the benefits that a move to a risk or condition based strategy is working for Both BP Shipping and Shell STASCO.

The main points that became clear following questions from the floor was that smaller companies suffer as a result of their lack of leverage with OEM’s in terms of negotiating alternative maintenance strategies to align with a CBM approach and that they require support from classification societies to ensure that they are able to  operate on an equal footing. It is also quite obvious that CBM could become an elitist  approach only available to the few further widening the gap in opportunity terms for small to medium operators to offer a real alternative and to perform on the same stage.

One specific issue faced by the smaller operators is the quality of maintenance manuals provided by the manufacturers and the potential for significant gaps in maintenance data following acquisition of an existing ship. These were two areas where the standards setting agencies, i.e. Class, could offer significant support.

The move towards a risk-based approach in ship maintenance management – the latest blog by Danny Shorten”As a result of improvements in design and a tendency to reduce the need for running repairs, there has been an increase in the use of disposable components, for example, sealed-for-life pumps. Couple this with the ever present need to operate at a reduced cost means that nowadays the engineer is tasked with developing strategies to understand and react to condition thus avoiding or extending scheduled intervals of intervention until necessary. This approach is broadly described as a risk-based approach.” Read more here
