Material Materingen, the Holland-based company trading as Harbinger B.V., have facilities throughout the world for conducting steel-thickness surveys on ships and other steel structures. The company, which uses the ultrasonic method of thickness measurement, is independent of ship-repair companies and classification societies, and can keep records on behalf of the shipowner to show where and how much the plating and other steelwork is corroding throughout the life of the ship. Such information is important in planning a ship's drydocking programme. The company's surveyors work without needing assistance from the shipyard, and can take up to 100 measurements per hour; staging is not required, and the work can, if required, be carried our during a voyage. The company has been operating successfully for a number of years, and results of its surveys are recognised by governmental authorities and the classification societies. Customers are usually shipowners, but much work is done for classificaiton societies when their own personnel are not available. The article also gives some information on the company's other activities, which include agencies for sacrificial anodes and for various types of ships' and other equipment.
