Marine prop shaft kept dry for maintenance

nufox marineHere at Nufox, we have extensive experience of working in the marine industry, often with suppliers to customers that include the world’s navies, merchant navies, oil tankers and ferries.

We offer optimal solutions to our customers exacting standards and requirements and become an integral part of their projects.

By way of typical example, we were recently asked to find a solution to the problem of working on a ship’s prop shaft in situ but in a dry environment. Normally prop shafts are wet and the high rotational speed helps to dissipate the water that comes in from the outside.

In order to carry out essential maintenance whilst at sea the shaft has to be dry. The problem was how to form a seal that would be in place and only used when required.

Working closely with the prop shaft suppliers, we designed a circular collar placed around the shaft which was inflated to give a watertight seal. Made from a high-grade compound, the inflation fittings are installed and bonded during manufacture.

The seals would normally be fitted during manufacture and assembly but can be fitted retrospectively allowing repairs to be done at sea, should this be required.

Such was the success of this design, that this type of seal is now in use in many vessels across the world. Just one of many examples where our experienced technical designers have provided added value in the marine environment and beyond.

Please contact us if you have a current or forthcoming project with which we can be of assistance.
