Main Engine Damage Study
In 2005, The Swedish Club presented the findings from a 6-year study of main engine damage (1998-2004). This report sets out the results of a follow-up study, spanning the 7-year period 2005-2011.
The objectives of this survey are to update the analysis published in 2005, identify new claims trends, review and reinforce the Club’s Main Engine Damage Loss Prevention Programme. The fundamental aim is to reduce the frequency/severity of main engine damage.

The Club’s H&M claims in the 1998-2004 and 2005-2011 periods are shown in Graphs 1 and 2, respectively.
Seven claims categories are represented. It can be seen that in proportion the machinery claims have risen since 2004. Machinery claims accounted for 45% of H&M claims in the earlier study, increasing to 51% in this period.

For the purposes of comparison, the new investigation followed the same methodology adopted for the earlier survey. Only claims exceeding USD 10,000 or more (deductible included) were considered. It should be borne in mind, however, that the costs cited understate the true scale of the problem, as claims falling below the deductible tend not to be brought to the Club’s attention.
In cost terms the proportion of Machinery claims have also risen. In the 2004 analysis the cost of Machinery claims accounted for 32% of the total H&M claims costs. In the most recent analysis this proportion has risen to 36%.
The Swedish Club has always had a proactive policy, directed at raising awareness of main engine damage and encouraging manufacturers to respond with new and more effective measures for reducing the frequency of engine damage.
The Swedish Club provides members with a range of cover, including Protection and Indemnity (P&I), Freight Demurrage and Defence (FD&D), Marine & Energy and Ancillary covers and as of 1 September 2012, the Club had 1,041 vessels entered for P&I, 744 for FD&D and 1,484 for Hull and Machinery (H&M).

Main Engine Damage Study
The average cost per machinery claim has risen from USD 323,000 to USD 519,000 over the past seven years. As in the previous survey, machinery claims are grouped into six categories (Tables 3 and 4). There were 982 machinery claims in the 2005-2011 period, costing USD 509,266,000.

Machinery claimsMain engine damage remains by far the most expensive category, contributing 39.6 % of total machinery claims cost (46.0 % in the earlier study) and 14.0 % (14.4 %) of total H&M claims cost. During the relevant period the Club's deductible level has increased by 3% per year.
Graph 5 shows that the frequency of Hull & Machinery claims (claims number/Club entry) is approximately 0,2 claims per vessel and year over the past 10 years.

Main Engine Damage Study
Graph 6 is an overview of the main engine claims trend over a 23-year period. The trend line has broad similarities to that shown in Graph 5 (for all H&M claims) and shows the trend has stabilized to almost 0.04 claims per vessel and year.
Graph 6. Main engine claims and trends, 1988-2011
As mentioned above, this trend is reflected in the main engine damage statistics, with the average cost rising 52%, to USD 545,000 from USD 358,000 (1998-2004).
Main engine damage claims involved, on average, 3.4% of all vessels entered for Hull & Machinery with The Swedish Club for the period 2005-2011. The total cost of main engine damage between 1988-2004 was almost USD 180,000,000, adjusted to 2011’s level. The latest survey records 370 main engine claims costing USD 201,500,000.
The fact remains that medium speed engines continue to be over-represented in the claims statistics. Graph 7 shows that, while 17.5% of entered vessels had medium speed engines, these vessels accounted for 30.2% of engine damage costs. The corresponding statistics for the earlier study are 19.5% and 48.1%, respectively.
Graph 7 shows that the proportion of entered vessels with The Swedish Club with low speed engines has increased somewhat, whilst repair costs have risen significantly. This rise in costs can possibly be attributed to the boom years in shipping, when repair capacity and spare parts availability were scarce.

Main Engine Damage Study
Tables 5 and 6 focus on the eight most common damaged parts in the main engine claims category. In terms of numbers and total cost, turbocharger damage remains the most common and costly engine component, accounting for 145 of the 370 claims and almost USD 50,000,000 of the USD 201,500,000 total cost. 114 of the 145 turbocharger claims involved low speed engines.
In terms of average cost, crankshaft failures produced the most expensive claims, USD 1,447,000 per damage. This is a significant increase to the USD 722,000 average cost in the period 1998-2004.

Turbocharger damage remains the most common and expensive damage for low speed engines. Crankshaft damage is the most expensive medium speed engine damage category. There were 12 such claims in 2005-2011, with an average cost of USD 1,130,000.
Our definition of multiple parts is damage where various engine parts are involved. For example a claim involving off-spec bunkers causing damage to fuel system components, cylinder liners, pistons and turbochargers.

Inferior maintenance and/or repair are by far the most frequent cause of damage. We have noticed numerous cases where damage occurs shortly after the engines have been overhauled by ship or shore staff. This emphasises the importance of having experts in attendance during major overhauls.
RisksBefore a critical job is started the risks have to be identified. If they are not identified it could lead to very expensive machinery failures or even loss of life.
In numerous cases there were risk assessments in place but a failure in fully assessing the areas of concern. The reason for this might be that the crew did not recognise the benefit of following correct procedures. This means that the company has not been able to establish a safety culture onboard and explaining the importance and benefits of approved procedures.
Recurring issues f Insufficient planning
f Insufficient experience/training
f Non-compliance with company procedures
f Unclear procedures, not comprehensive enough or have not been implemented
f Not having experts attending major overhauls
Limited experienceIt is a well-known fact that there will be a shortage of experienced seafarers in the near future. This has been highlighted before in our publications but it is worth repeating again. There is a risk that officers are being promoted before they have acquired the necessary experience for senior command.
To ensure that seafarers have the required knowledge it is essential that they receive proper training. This should be clearly defined in the SMS (Safety Management System) of what is required of them.
It is further imperative that the maintenance of all engine components is included in the PMS (Planned maintenance system).
www.swedishclub.com 14
Main Engine Damage Study
Prevention f Implement Onboard Fuel Management and fuel system
audits. During these audits, the various parts (including separators) of the fuel treatment plant should be checked for proper function.
f It is imperative to monitor the quality of the lubrication oil. Samples of lubrication oils should be sent ashore for analysis at least every three months.
f During major overhauls it is highly recommended to have an expert in attendance.
f To ensure a long service life for the boiler it is important to implement a correct boiler water treatment.
f To prolong the service life of the economiser it is very important to keep the economisers clean. This will increase the service life and minimise the risk of soot fires.
f Invest in employee training.
f Carry out comprehensive audits and inspections.
Fuel managementAn in-depth investigation of multiple machinery claims shows that a lot of engine damage is caused by off-spec bunker. It is likely that this was avoidable or could have been minimised if proper Onboard Fuel Management had been implemented and followed at all times.
Effective Onboard Fuel Management will significantly reduce the risk of engine break-down and lengthy/costly repairs. The components included in the fuel oil system are: bunker tanks, settling tanks, service tanks, various pumps, heaters, filters and separators.
Unfortunately there are still some owners/operators who do introduce untested fuel into their machinery to see how it works, which can lead to catastrophic consequences.
During normal operation and over time, sediment including cat fines will accumulate at the bottom of the settling and service tanks. In heavy weather, the accumulated sediment could dislodge and clog filters, heaters and separators. In addition, dislodged cat fines could very quickly cause abnormal abrasive wear to various engine components. Over the years we have seen numerous “cat fine-related” damage to main engines resulting in towage and very costly and lengthy repairs.
It is therefore essential that settling and service tanks are drained completely and manually cleaned at regular intervals.
FindingsThe primary finding is that medium speed engines still account for a disproportionate number of machinery damage claims. Furthermore, the average cost of main engine claims (on a per year/vessel basis) is twice as high for medium speed engines, compared to low speed engines.
f Since 2004, the average cost of a main engine damage has risen by 52%, from USD 358,000 to USD 545,000.
f Medium speed engines still represent a disproportionately large share of main engine damage costs. Vessels with medium speed engines accounted for 17.5% of Club entry yet generated 30.2% of total main engine damage cost. In comparison with a low speed engine, a medium speed engine has more moving parts and operates at a much higher rpm. As a consequence, the medium speed engine is more susceptible to breakdowns.
f Turbocharger damage remains the most common and expensive damage category across all engine types, accounting for 145 of the 370 main engine claims, at a cost of USD 49,800,000 or at an average cost of USD 344,000.
f Crankshaft failure is the most expensive damage to medium speed engines, with 12 failures at an average cost of USD 1,130,000.
f Inferior maintenance and/or repairs caused 52 casualties at an average cost of USD 576,000.
Future analysisThe Club will closely monitor and compare the performance of conventional two stroke engines with electronically controlled engines. When sufficient statistical data is available, the Club will release an update to this report.
Furthermore we will monitor the effects/claims of slow steaming practices, which are adopted in the shipping industry today.
The Club will continue to share engine damage information with members and draw the attention of manufacturers to the survey results. Upon request, Club members will have full and exclusive access to the comprehensive data relating to leading engine makes and models.
