Abstract:

The sealed sterntube has long been an essential component to most merchant fleet vessels, the aft seal provides protection from water ingress while preventing oil leakage from the sterntube. But given the development of advanced seawater lubricated bearing systems, that eliminate the pollution risks associated with oil‐lubricated systems.

Do we still need the sterntube? The answer, it seems, is no.

The results from a joint research project involving Thordon Bearings, Shanghai Merchant Ship Design & Research Institute (SDARI‐CSSC), National Technical University of Athens(NTUA) and American Bureau of Shipping (ABS) indicate that a ship’s sterntube can be completely omitted to make better use of the available space.
