Watermaster’s own state of the art Dredging Cutter Pump is an essential part of the Watermaster concept. Together with the Integrated Watermaster Operating System (IWOS) It enables 50 % to 100 % more effective pumping time compared to traditional machinery. Submersible pump allows working in very shallow waters or even from the dry land. It includes two cutter crowns for different kinds of soils and an integrated vegetation cutting knife system. The maximum pumping distance is 1,5 km. Watermaster is fully amphibious also when operating with the Dredging Cutter Pump.

Large Work Area Maximizes Productivity (IWOS)

Watermaster's rake attachment is a 2,75-meter wide tool for removing trash and vegetation – both floating and rooted.

Two attachments are available for piling work; the Piling bucket for wooden piles and the vibratory piling tool for both metal sheets and wooden piles. Watermaster grabs the piles from the side and can thus handle longer piles.

Piling Bucket

Shallow water work has traditionally been divided between excavators and conventional cutter suction dredgers. Excavators have been used for the more shallow and narrow parts and conventional dredgers for deeper and wider areas.The Watermaster Amphibious Multipurpose Dredger single-handedly covers all shallow water work from dry ground up to the depth of 6 meters. Watermaster is specifically designed and certified for both water work and for working from the land side.Suction dredging, excavating, raking and pile-driving - all applications cost-effectively with one versatile machine.Do more with less by using multipurpose Watermaster technology.

WORK DEPTH

Watermaster can independently move,  anchor and work in the whole shallow water  area from dry ground to 6 meters depth.  Traditionally same work area requires many  machines and assisting units.

VERSATILITY

Watermaster excels in suction dredging,  excavating, pile-driving and raking.  Watermaster’s work efficiency and anchoring  stability is in a class of its own thanks to the  smart Watermaster operating system (IWOS).

WATERMASTER IS FULLY AMPHIBIOUS

MOBILITY

Watermaster is a fully amphibious vessel  that does not only float, but truly masters  the water. It is self-propelled and can travel  considerable distances in water to reach  the work site (max. speed 4 knots). On dry  ground Watermaster has the ability to walk.  Watermaster is stable, safe and tested.

WATERMASTER IS SPECIFICALLY  DESIGNED AND CERTIFIED FOR  SHALLOW WATER WORK

WATER SAFETY

Watermaster is fully capable and certified  for working safely both in water and from  land side. The design is approved by Bureau  Veritas. Each Watermaster is inspected by a  maritime authority.
