HVAC&R | Dredgers

Through construction and maintenance of much of the global maritime infrastructure, the dredging industry has severely impacted the world economy. The dredging industry plays a huge role in the construction and maintenance of ports and waterways and reclaiming land worldwide.

Not your typical HVAC system

Trailing suction hopper dredgers, cutter suction dredgers and backhoe dredgers are the workhorses of the commercial fleet. Imagine a 100 m. cutter suction dredger with a capacity exceeding 30.000 kW, laying in the burning sun in the Gulf of Oman. It’s drill head pounding through layer after layer of rock and debris on a depth of 40 m. Can you imagine the amount of heat that will be generated under these extreme conditions? Clearly, this requires a little more than just a conventional HVAC system.

The most powerful dredgers worldwide

Dredgers are generally very complex vessels and require specialist knowledge of the vessel, its purpose and its equipment. A lot of vibrations occur, so rigid building of the system, units and equipment is a necessity. Heinen & Hopman has been selected to supply the HVAC&R for some of the largest and most powerful dredgers in the world, so we have the know-how to cope with the difficulties and challenges that arise in the dredging business.

Our working method
