  • 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.

  • 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.
