Sterntube Seals
FAQs
"What's in the service package?"
Everything that is required to change the seals including the precise alignment of the liner.
"Can the job be done afloat?"
If the ship can be ballasted by the bow so that the shaft is out of the water then the seals can be bonded provided there is no other damage. This is generally only practicable with tankers and bulk carriers because the ship has to be trimmed in such a way that the seal is approximately one metre above the water line.
"How long will the job take?"
Three days for a standard forward and aft seal on the one shaft, provided that other drydockk work does not interrupt our work, CPP installations and split liners will take longer
"Can we replace the sealing rings without pulling the shaft?"
Yes, by cutting the sealing seals, then vulcanising the new seals with the aid of a bonding jig, and special two component adhesive.
"Where do our engineers go?"
Worldwide
"What am i likely to need to do at the next docking?"
Contact us first, we can check our service reports and advise what spares are required. For instance, a distance ring may be required, or the liner may need to be machined or a new liner supplied.
