| Condensate drain | per watch routine or as required by engine room procedure |
|---|---|
| External/visual inspection | every 3-6 months |
| Backpressure measurement | annually, or per the connected engine maker's schedule |
| Internal inspection where accessible | per the engine maker's or class overhaul interval, commonly multi-year |
| Exhaust backpressure | should not exceed the connected engine or genset maker's stated maximum allowable backpressure - confirm against the engine manual, not the silencer alone |
|---|---|
| Shell wall thickness | any significant thinning found by visual or ultrasonic check should be assessed against the maker's minimum wall guidance before continued service |
| Insulation/lagging surface temperature | external surface temperature should be checked against the maker's or shipboard safety limit for accessible surfaces - confirm the local requirement |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Class interest is generally limited to confirming the silencer does not compromise engine performance (backpressure) or fire safety (lagging integrity, hot surface protection); periodic visual condition checks are typically part of the general engine room survey rather than a dedicated machinery item.
Estimated lifetime: Marine exhaust silencers of this chamber/absorptive type typically give many years of service, often in the order of 10-15+ years, before shell replacement is needed, depending on condensate exposure and maintenance - confirm against the maker's guidance.
