ALSTOM - COMPLETE ELECTRIC POWER AND PROPULSION PACKAGES

ALSTOM - COMPLETE ELECTRIC POWER AND PROPULSION PACKAGES ALSTOM is the leading supplier of electric power and propulsion packages for the naval market. Drawing on a century of experience in significant naval projects, ALSTOM is the industry's first choice for electric power and propulsion systems. Whatever the requirement for electric propulsion, be it synchro-drives, cyclo-drives, PWM with synchronous motors or Advanced Induction Motors (AIM), ALSTOM can provide a solution, from concept studies and initial design though procurement to installation, commissioning and through-life support, including integrated logistic support. TYPE 45: ADVANCED INDUCTION MOTORS AND PULSE-WIDTH MODULATED (PWM) SYSTEM The recently ordered Type 45 Daring Class Destroyers for the Royal Navy will be powered by two 20MW ALSTOM Advanced Induction Motors and controlled by our latest PWM system, the VDM 25000. ALSTOM is also electrical integrator and supplier of the 21MW alternators for the WR21 gas turbine, the diesel generator sets, HV switchboards, propulsion management system and associated propulsion auxiliaries. LPD(R) AND AUXILIARY OILERS: MOTORS AND CONVERTERS HMS Albion and HMS Bulwark have now replaced the aged HMS Fearless. They have been fitted with two 6MW ALSTOM motors, controlled by two 12-pulse converters. The two Wave Class Auxiliary Oilers, built for the Ministry of Defence for operation by the Royal Fleet Auxiliary, are powered by two 7MW tandem motors on a single shaft and controlled by two 12-pulse converters. The diesel generator sets, switchboards, HV converter, ship service transformers, thrusters and integrated platform management systems have also been supplied by ALSTOM. TYPE 23: DC ELECTRIC MOTORS There are now 16 of the Duke Class Frigates in service with the Royal Navy, which have provided the backbone of the United Kingdom's maritime anti-submarine force for over 12 years. The ALSTOM DC electric motors have steamed over 2.5 million nautical sea miles without a serious breakdown. ALSTOM is rightly proud of the performance of its equipment in this harsh naval environment and believes that the equipment fitted in the emerging classes of Royal ALSTOM's PWM converters are a significant part of ALSTOM's power and propulsion systems enabling better system ALSTOM is supplying significant elements of the electrical power and propulsion system for the Royal Navy's new class of Type 45 Destroyers. ALSTOM's Advanced Induction Motors, built to the exacting requirements for naval propulsion, are smaller and lighter than the traditionally used synchronous motors, making them particularly suitable for naval vessels where space is at a premium. Navy vessels will be equally as rugged. ELECTRIC SHIP TECHNOLOGY DEMONSTRATOR (ESTD) The Electric Ship Technology Demonstrator, at the Whittle Research Centre at Whetstone, provides a facility to de-risk electric propulsion for future warships. An AIM and converter, together with MV and LV switchboards and loads, filters, transformers and a 4-quadrant load allows full simulation of future platforms. Testing is also being carried out on novel energy storage systems, such as flywheels and fuel cells. FUTURE AIRCRAFT CARRIER: PROPULSION SYSTEM As part of the Aircraft Carrier Alliance, ALSTOM is the power and propulsion system authority for the preliminary design studies of this major warship programme. An Integrated Electric Propulsion System, offering through life cost benefits, is being advocated with a number of propulsion drive train options being considered. An IEP system also facilitates the use of a novel aircraft launch system called EMCAT (Electro-Magnetic Catapult) exploiting ALSTOM's converter expertise and linear motor technology. LANDING HELICOPTER DOCKS: PROPULSION SYSTEMS Mistral and Tonnerre, the French Navy's new projection and command vessels, will be equipped with ALSTOM's Mermaid™ propulsion systems. Each vessel will be equipped with two variable frequency propulsion systems, harmonic filters and a power management system.
