2. The EcoMarine Propulsion Systems Corporate Team
The Force behind Marine Electric Propulsion
EcoMarine Propulsion Systems is a joint venture comprised of three world-class businesses
whose complementary expertise is the force behind marine electric propulsion and a pioneer
for the application of alternative green power sources for the tug/barge marketplace and
beyond worldwide. Offering an affordable electric propulsion drive that offers fuel savings,
reduced emissions, lower maintenance costs, simplicity of operation and improved vessel
environment with regard to noise and onboard sound level reductions.
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.
Industrial Power Systems, Inc. designs and builds quality electrical controls, switchboards
and switchgear. Formed in 1981, they have designed and built over 10,000 control panels
covering a broad electrical spectrum. Their strength is in complex and innovative
applications, especially where custom design and engineering is a requirement. The
company has vast experience in marine switchboards and controls and has built to ABS and
USCG specifications for cruise ships, casino boats, workboats, tankers, tugs, barges,
dredges, riverboats, ferries, pleasure craft and military vessels.
Comprehensive Power, Inc. is a leading designer and manufacturer of high-performance permanent
magnet motors, generators, controls and drives. Based in Marlboro, Massachusetts, the company is an
enabling supplier and partner of leading firms in the mobile power, distributed power and renewable
energy sectors, helping them produce dynamic energy solutions. Comprehensive Power has supplied
power conversion equipment for submarines, self propelled acoustic targets, robots, vehicles, wind
turbines, drill rigs, transport systems and industrial equipment manufacturers for over eleven years.

6. 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 Voltage from TeraTorq® Inverter Modules (TIMs)
system, by anyone, in an emergency. into a motor. High frequency “noise” is contained
Fault currents are quickly and electronically by phase inductors.
eliminated, reducing arc flash hazards.

7. 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.

8. Vessel Design & Operational Benefits
Fuel Monitoring and Management
The system accommodates a fuel management system
(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) Example FMS screen.
awarded 7/12/12.
Total Ship System Approach

9. 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 CAT® C32
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.

22. Hybrid Architecture
Standard Diesel-Electric Architecture
Electric power is generated from fuel
Variable frequency drives run electric motors
Diesel generator loading changes instantly when system
requests more or less power
Regenerated power is lost - dissipated in grid resistor
Connecting energy storage (battery) to the DC bus changes
system to a Series Hybrid Architecture
Regenerated power can be captured
Diesel load changes can be smoothed, reducing emissions
Diesels can be taken off line when lightly loaded
