Marelli Motori supply electrical motors for north America’s largest dredge

Marelli Motori has recently supplied two 6000HP motors to Callan Marine for their General MacArthur vessel, the latest addition to the Callan Marine’s dredge fleet which, upon completion later this year, will be the largest and most powerful dredge in North America with a total of 24,000 installed horsepower.

 

The two Marelli Motori motors will operate the large deck pumps that carry the slurry from the cutter to the shore; these motors have the highest kW/kg ratio ever realized on 710 frame sizes.
As overall size is vital in marine applications due to the limited space available for on-board equipment, the motors also have an enhanced two sided ventilation using 4 auxiliary fan motors and 2 custom air to water heat exchangers to give superior cooling of the stator and rotor core. 

 

 

A spokesperson for Callan Marine said “We are proud to have selected Marelli as the motor of choice for this landmark vessel. The General MacArthur required a dredge motor that promised dependability and tremendous power - Marelli Motori provided both”.
