The Force behind Marine Electric Propulsion
Ocean Tug/Barge Engineering has either directly designed, or been a fully participating engineering
partner, for 38 operational AT/B’s in the US market over the span of a quarter century. They have
engaged in six new build projects in the US as of 2006, and one overseas. The firm has also now
entered the international marketplace, with units under design for service in the Far East, and Eastern
Europe, and is pioneering the application of alternative "green" power sources for the tug/barge
marketplace worldwide. The firm has also expanded its product range with the introduction of new,
high technology harbor and offshore tug designs.

Vessel Design & Operational Benefits
A DC Main Bus Means Reduced Electromagnetic Emissions/Harmonics
Great benefit in running wiring for the system and results in fewer issues for onboard electronics.
Less Complexity In Operation There is no need for complex generator
control/switchgear or complicated generator AC synchronizing equipment.
Generator phase differences and frequency differences are not an issue.
No separate field excitation generator needed and thus no excitation-related failures.
Power management is simplified vs. conventional D/e drives.
Inherent Redundancy and Safety Drive Electronics units can be redeployed within the
system, by anyone, in an emergency.
Fault currents are quickly and electronically eliminated, reducing arc flash hazards.
Voltage from TeraTorq® Inverter Modules (TIMs)
into a motor. High frequency “noise” is contained
by phase inductors.

Vessel Design & Operational Benefits
Small and Lightweight Drive Package PowerRing components are more compact and
lighter than conventional AC or other DC drive systems.
Reduced sizes for new vessel machinery and ease of refit into existing vessel designs.
Simplicity of Troubleshooting & Repair Interchangeable drive line components. Drive components can safely be handled by
individuals and small work crews. Unit exchange with the factory allows for a quick
and cost-effective turnaround for replacement of many drive line items.
Worldwide service for the propulsion system is planned.

(FMS) to monitor fuel use in both real-time and trend line formats.
FMS can be configured to interface with GPS to provide matching speed, location, power and fuel use information.
Wheelhouse Configuration The wheelhouse displays and controls can be customized
for the particular vessel and service. Integrated bridge controls are available.
Direct drive means no reverse reduction gear nor associated maintenance.
ABS The system will be delivered with full ABS certification. ABS Certificate of Product Design (TIM-270,TFM-521)
awarded 7/12/12.
Total Ship System Approach Single-source, warrantied, full vessel electrical solution,
including ship service switchboards and distribution panels.

Vessel Propulsion & Operational Benefits
Engines can be taken off-line, reducing wear and maintenance.
Engines can operate at varying speeds; there is no need to synchronize system components.
Propellers can turn slowly (at full rated torque, forward or reverse) with no clutches.
Interfaces with Z-drives and controls, reduction gears, VSP units, CP propeller systems, and bow thrusters.
Power module failure in a drive electronics component yields proportional loss of capacity, not a complete propulsion line power failure.
Engine failure still permits balanced thrust from both propellers.
6 millisecond response to prop jamming reduces impact damage and enables jam clearing.
Faster shaft reversing time provides faster stops as well as better maneuverability.
