After two months on the slip, Ocean Recovery slid back into the water today. With a fresh coat of paint, new anodes and a long list of work completed, she is a big step closer to being ready for environmental work.

Volunteer engineer Chris Purkiss explains why ships like ours need to brought out of the water every five years to have their survey completed. Most domestic commercial ships operating in Australian waters are required to have a valid certificate of survey. The certificate is issued when a ship complies with Australian laws and standards.

Aluminium anodes are placed under the ship to take the bulk of the corrosion before the ship’s hull itself. These need to be replaced next time the ship is slipped onto dry dock.
