Swedish Club issues guide on preventing marine engine damage

Marine insurance firm The Swedish Club has released a guide entitled Main Engine Damage that offers advice on preventing damage to a vessel’s main engine.
A summary of the advice is below:
- Implement robust onboard bunker fuel and lubrication oil management systems.
- Carry out drip sampling when bunkering. Avoid consuming the bunker fuel until analysis results are available.
- In addition to onboard testing of lubrication oil, submit samples for laboratory analysis at regular intervals, at least every third month.
- At regular intervals, carry out system checks of purifiers and filters for both bunker fuel and lubrication oil systems.
- Ensure that maintenance manuals are at hand and that proper tools are available and calibrated. Crew members must have the necessary training and experience to carry out maintenance.
- It is highly recommended that engine maintenance is carried out as part of a computer based PMS (Planned Maintenance System), linked with the onshore organisation.
- During major overhauls it is recommended that an expert from the manufacturer is in attendance – consider a formal service agreement.
- Always take engine alarms seriously, for example oil mist detection, and investigate thoroughly. A fully functional alarm system is essential for the safe operation of the main engine.
According to the club, main engine claims account for 28% of all machinery claims and 34% of the costs, with an average claims cost close to USD $650,000.
The claims frequency has for the last ten years been steady at between 0.020 and 0.025 claims per vessel and year, with passenger vessels/ferries having the highest frequency with 0.066 claims per vessel and year.
Vessels propelled by medium/high speed engines, meanwhile, have a claims frequency 2.5 times higher compared with slow speed engines; lubrication oil related failure is the most common cause of damage.
The most expensive type of damage is on crank shaft/bearings with an average cost of USD 1.2 million per claim.
