Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Shaft seal leakage | any continuous water or oil leak beyond the maker's stated allowable drip rate should trigger seal renewal - confirm the figure against Veth's manual |
|---|---|
| Propeller tip-to-tunnel clearance | typically only a few millimetres for this size class and should not be adjusted without maker guidance - confirm against the drawing for this unit |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Bow/stern thrusters are class machinery items subject to periodic survey; class wants confirmation of shaft seal integrity, alignment records, and a function test of the remote control and alarm system.
Estimated lifetime: Not typically expressed in running hours for an intermittent-duty tunnel thruster; gearbox and seal service is normally scheduled on a calendar/hours-whichever-first basis per the maker's PMS.
