ClassNK did not have in place a system which ensured that updated service advice from the engine manufacturer was being implemented on board ships with engines which its surveyors were routinely and regularly surveying.
The ATSB is satisfied that with improved awareness of the prevailing state of the machinery, the actions being taken by ClassNK will adequately address this issue.
ClassNK advised that they were in discussion with MAN B&W about obtaining engine design and service information and that all relevant departments would share any design change information.
ClassNK also advised that survey reports are checked by head office and damage information arising from inspections, or from notices received from the equipment manufacturer, is analysed and recorded in the company survey database. This information is brought to the attention of, and made available to, class surveyors through a monthly damage list which is issued to all class surveyors. This information is also available to surveyors through company internal document systems.
The ATSB is satisfied that the action taken by ClassNK adequately addresses this safety issue.
