Marine Duty

Marine duty motors offer energy efficiency and reliability above deck and below deck with specially designed motors to keep essential and non-essential services operating.

Engineered for Reliability in the Harshest Marine Conditions

Marine duty motors are utilized across the marine industry on military vessels, offshore platforms, passenger ships and ocean-going vessels. Reliability is most important for electric motors utilized in the extreme operating conditions associated with marine applications: i.e. salt laden, humid and corrosive atmospheres.

prevents degradation from salt sprays and humid conditions.

Explore the key benefits

Marine duty motors are purpose-built to deliver reliable performance in some of the most demanding environments on earth. Customers select them for their ability to resist corrosion, tolerate high humidity and maintain performance under continuous exposure to salt, moisture and vibration.

For all marine duty

Marine duty is available for all applications above and below deck such as: winches, cranes, propulsion, bow thrusters, pumps, compressors and more.

Corrosion resistance

Specialized marine-grade paints, coatings and stainless-steel hardware prevent degradation from salt spray and humid conditions.

Compliance & Standards

TAC is a procedure used to approve standard or routinely manufactured designs. Once a design receives approval, it remains valid for all future components built to that identical design. Approvals are typically issued by agencies such as IEEE 45, USCG, ABS, Lloyd’s Register and DNV.

Continuous reliability

Designed for 24/7 operation on deck, in engine rooms, or below decks—where downtime directly impacts mission or voyage schedules.

Ingress protection

Spraytight (IP55) and watertight(IP56) protection prevent moisture ingress, reducing corrosion and extending motor life in harsh marine environments.

Premium efficient electrical designs

All motors meet or exceed NEMA Premium® efficiency energy requirements for US, Canada and Mexico.
