Cathelco protects historic naval vessel in Pearl Harbour

Earlier this year, after refitting work at the BAE Systems Hawaii Shipyard, the USS Missouri returned to her permanent berth in Pearl Harbour where she will attract thousands of visitors a year as a museum ship.

The new Cathelco equipment has the advantage of using the latest ICCP technology providing greater effectiveness until the next drydocking in 20 years time, while reducing the number of anodes and hull penetrations. The forward system has involved the installation of a 100A thyristor control panel which is wired to two 50A linear loop anodes and reference electrodes mounted port and starboard on the hull. The advantage of linear loop anodes is that they emit a relatively high output from a small surface area, therefore fewer are required to achieve the necessary protection levels.

The more powerful aft system consists of a 300A control panel, two 150A anodes and reference electrodes. All of the anodes and reference electrodes are designed to be diver changeable and can be replaced in future, if necessary, without the need for drydocking.
