In May 1988, Dredging International began dredging at Leam Chabang, Thailand, where the Thai government was creating a port.

Using their 850mm (33-inch) cutterhead dredge Amazone, D.I. began the project consuming between 500 and 700 teeth per day, depending on where they were working. Many different types of hardfacing materials were tested on the teeth, including all iron-based chromium and complex carbide types. A significant step towards the increase of cutter tooth life was made by using a tungsten carbide hardfacing product manufactured by Durum of Krefeld, Germany. The first results, with a minimum product applied, increased the life by a factor of four.
