| Nozzle inspection/renewal | typically every 12 months, more frequently for abrasive or high-solids cargo residues |
|---|---|
| Gear train lubrication service | per maker's schedule, commonly annually |
| Full strip-down overhaul | typically every 2-3 years or per maker's recommendation, aligned with the tank cleaning system survey |
| Seal/packing renewal | at each major overhaul or on evidence of leakage |
| Nozzle bore wear | monitored by loss of spray pressure/pattern rather than a fixed dimension - renew per the maker's condition criteria for this machine |
|---|---|
| Rated coverage and flow | re-verify the nameplate rating (approximately 8 m coverage diameter, 10 m3/h at 6 bar for this unit) against actual cleaning performance if effectiveness is in question |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Tank cleaning machines integrated with a fixed cargo/ballast tank cleaning system are generally reviewed as part of the vessel's cargo system survey; class expects maintenance evidence where the machine interfaces with the cargo or inert gas system.
Estimated lifetime: Service life is normally expressed in years of tank-cleaning campaigns rather than running hours; internals (nozzle, gears, seals) are consumable and replaced on condition rather than the unit being run to a defined lifetime figure.
