There was record attendance at the Maritime Propulsion Services BV (MPS) open day on May 23 when more than 200 delegates from shipyards, classification societies and workshops around the world gathered together in Drunen. Apart from the four propellers which were in the workshop for repair, on display were some of the latest developments in quality control as well as repair procedures and technology. These included state of the art nondestructive ultrasonic techniques to inspect either for porosities in bronze castings or weld repairs on propeller blades.
