Case Study

Fitting New Anodes

The Problem

As part of routine maintenance for a marina on the south coast of England a commercial dive company was tasked with fitting sacrificial aluminium anodes to steel piles to reduce the corrosion.

The issue being that the anodes need to be in contact with bare steel but the piles were covered in paint and marine growth including algae and barnacles. They needed an underwater grinder that was powerful but light and easy to use.

The Solution

Having previously advised the commercial dive company on other jobs, EC Hopkins suggested the Hopkins GR05, 5" underwater grinder as due to its size it was more appropriate for this task than the dive companies larger GR29 grinder.

The GR29 takes a 9" or sometimes a 7" disc but the smaller 5" disc on the GR05 underwater grinder and its design, with a longer body meant it was an easy tool to control but with more than enough power to remove the marine growth and hard paint coating.

The divers using the GR05 complemented the tool for completing the task with minimum effort, removing paint, marine growth and creating an excellently prepared surface.

The GR05 is not meant to replace the GR29 but offers an alternative on small to medium jobs.
