Classification society ClassNK has released revised rules for the use of Condition Based Maintenance (CBM) in class surveys, with the organisation hoping to promote the expanded use of CBM technology in the marine sector.
CBM Guidelines (Edition 2.0) follows on from the original ClassNK guidelines (First Edition) published in 2019 and updated in 2020, detailing the required documents and the approval procedure necessary to substitute CBM in place of periodical overhaul inspections for class maintenance surveys.
The revised guidelines contain case studies based on risk and cost efficiency evaluation of CBM implementation projects as well as comparisons between CBM surveys and conventional surveys.
These case studies were created through joint research with a shipping company and engine manufacturer and can be utilised as guidance for the introduction of CBM-powered ship management, ClassNK says.
The guidelines also include the results of research carried out by a ‘CBM study team’ that included diesel engine and other manufacturers, as well as relevant industry parties already included in the IoS-OP (Internet of Ships Open Platform) consortium.
The guidelines are available to download free of charge via ClassNK’s website by those who have registered for the ‘My Page’ service.
