Description
WOODWARD
MODEL: 2301A
SPEED CONTROL
PART NO: 9907-014
REV. H
The Woodward 2301A is a dedicated electronic speed control unit designed to regulate and maintain engine speed with precision in marine propulsion and auxiliary power applications. As part of the broader Marine Control System category, this governor controller interfaces with actuators and speed-sensing inputs to deliver stable, responsive engine management. Reliable speed control is critical onboard vessels where load changes, sea conditions, and power demands require consistent engine performance to protect machinery and ensure operational continuity.
Key Features
✓ Electronic speed governor function providing closed-loop control of engine speed via actuator output, suitable for diesel and gas engines commonly found in marine installations.
✓ Specific technical parameters including voltage supply, input/output ranges, and response characteristics are configuration-dependent and subject to confirmation against the original system documentation and nameplate data.
✓ Designed for compatibility with Woodward actuators and speed-sensing systems; integration with other panels or controllers should be verified against the vessel’s existing control architecture.
✓ Intended for installation in a protected control room or machinery space enclosure; environmental suitability and mounting requirements should be confirmed prior to installation.
✓ As a revision H unit, this part reflects a specific engineering revision level — engineers should verify revision compatibility with their existing system to ensure drop-in serviceability without additional reconfiguration.
Marine Applications
✓ Main propulsion diesel engine speed governing on merchant vessels, offshore support vessels, and workboats where consistent shaft speed management is required.
✓ Auxiliary generator set control aboard container ships, bulk carriers, and tankers to maintain stable generator frequency under varying electrical loads.
✓ Thruster drive control systems on dynamic positioning vessels where precise engine speed response supports position-keeping operations.
✓ Pump drive and auxiliary machinery speed regulation on vessels with hydraulic or mechanical power take-off systems requiring governed engine input.
✓ Retrofit and upgrade applications where an ageing or failed speed control unit requires replacement within an existing Woodward governor control system.
Why Marine Engineers Choose
Woodward’s 2301A speed control has a long-established track record in marine and industrial engine management, offering a well-supported platform with a broad installed base. Its combination of reliable closed-loop speed regulation and compatibility with standard Woodward actuator systems makes it a trusted choice for vessel operators and engineers managing engine performance across demanding operational profiles.
Ideal For
Merchant vessels, offshore support vessels, platform supply vessels, tugboats, workboats, ferries, and any vessel operating diesel or gas engine-driven propulsion or auxiliary systems governed by Woodward control equipment.
Technical Support & Compliance
Technical support is available for remote troubleshooting, onboard diagnostics, commissioning guidance, repair assessment, and system integration advice — all subject to confirmation based on the specific installation. To confirm compatibility and suitability, buyers are advised to share nameplate photographs, the full part number and revision level, existing actuator model details, system wiring diagrams or drawings where available, vessel name, IMO number, and a clear description of the application scope. Compatibility and fitment are subject to confirmation against the supplied documentation.
