Auxiliary engine damage primarily down to human error - The Swedish Club

Jan 12 2018

An investigation by The Swedish Club into auxiliary engine damage has revealed that the majority takes place immediately after maintenance work.

 A key finding was that 55% of casualties occur within only 10% of the time between overhaul (TBO), corresponding to the first 1,000 hours or so of operation after overhaul. In most cases the damage occurs only a few hours after start up.


This report was created in response to the Club’s members’ concerns over damage to auxiliary engines – a significant segment of machinery claims, both in number and in cost.


Peter Stålberg, The Swedish Club’s technical adviser, explained: “Auxiliary engines run at high revolutions and have a common lubrication system for both cylinder and crank case lubrication. They are not under the same strict regime from the classification society as the main engine, and maintenance is often carried out by the vessel crew. 


“We see incorrect maintenance and wrongful repair in all too many cases, and poor lubrication management is also a major contributing factor to auxiliary engine break downs. With an average repair cost of more than $345,000, we cannot emphasise enough the principle that prevention is better than cure,“ he said.
