High Efficient Variable Speed Submersible Motor

Marine Innovation

Imagine the Impossible 

Build a motor that operates under 75 feet of seawater, in 20° C temperatures, with 32 psi of pressure on the enclosure, that will experience high torque loads with high axial and tangential bending forces, and handle a salinity of 3.5% while dredging silt, sand, and aggregate the size of a baseball, with a five year maintenance interval— and we want it in 18 weeks

Over 50 Years of Engineering Knowhow and Expertise 

We have been providing global solutions for more than 50 years to the marine industry. Our experience includes state-of-the-art couplings, diesel electric propulsion systems, and custom variable speed brake motors. We have the engineering knowhow and expertise in offshore, marine, and port applications. 

The solution consists of a high efficiency, variable speed, submersible 710kW, 12-pole, 690V Marathon motor with special marine epoxy coatings applied externally and internally for added corrosion protection, oil filled, has a special bearing systems for operating high torque loads, and an enclosure specifically designed to reduce the bending forces associated with this application. A special pressurized water tank that contains the same salinity and temperature of the seawater that the motor is exposed to was built to simulate the application to ensure performance.

Value Proposition

Highly engineered “Mission Critical” solutions.


At sea, on ocean platforms, or in ports, our products are essential to the marine industry: from highly engineered controls and power transmission products to low and medium voltage motors that operate in the harshest environments and ambient conditions.  

We provide market leading solutions that reduce energy consumption, improve process throughput, provide sustainability, and increase productivity and uptime. 

 

High efficiency mechanical solutions are at the cutting edge of what we do best. We are recognized for producing reliable solutions that solve problems in critical applications where performance is crucial.

  • The Jaure® and Kop-Flex® brands provide innovative solutions to coupling problems incurred in the marine industry that provide years of trouble-free performance.

 

We have an earned reputation for providing critical control solutions.  Benshaw® has been a leader of controls for over 40 years, providing low and medium voltage solid state starters along with medium voltage drives for “Mission Critical” applications. Custom control and protection algorithms optimize the motor’s performance, saving energy and reducing unnecessary downtime.

Regal has been a leader in the motor industry, creating motors and generators that are designed to work in the high performance and extreme conditions of the marine industry.
