Dredging

Diesel-powered engines built for nonstop dredging performance.

Dredging pushes equipment to its limits. Constant load, high torque, and long hours demand engines that hold up under pressure. Laborde Products supplies power built for that reality, delivering mechanical reliability, consistent fuel performance, and easy service access when the job can’t wait. Each engine is designed to handle sustained load, maintain steady output, and keep dredging systems operating at full capacity.

Engine Options for Dredging Applications

Dredging engines run under continuous load, driving pumps through abrasive material for hours at a time. That kind of work calls for mechanical simplicity, torque stability, and proven endurance.

Laborde Products supplies diesel power solutions from Mitsubishi Marine, trusted across the Gulf and inland waterways for their reliability and long-hour performance.

  • Mitsubishi R Series – The S6R-Y3 and S12R-Y3 cover 600–1350 HP, ideal for main pump applications. Fully mechanical and emissions compliant; these engines deliver high torque at low RPMs, steady fuel economy, and long overhaul intervals. They’re direct replacements for aging CAT and Cummins platforms on many dredging vessels.

 

Whether powering a cutter suction dredge, booster barge, or hopper vessel, Laborde helps operators match the right engine to their load requirements, layout, and environment.
