WOODWARD
SPM-A
SYNCHRONIZER
P/N: 9905-001 L
The Woodward SPM-A is a dedicated generator synchronizer module designed for use within marine control systems. Its primary function is to automatically match the voltage, frequency, and phase angle of an incoming generator to a live busbar before closing the breaker, enabling safe and stable parallel operation. Accurate synchronisation is a critical requirement in shipboard power management, preventing electrical faults, load surges, and potential damage to generating sets. This component forms an integral part of the marine power distribution and control architecture, supporting both automatic and manual synchronising sequences across a range of vessel types and power plant configurations.
Key Features
✓ Automatic synchronisation of generator sets, matching voltage, frequency, and phase to the running busbar prior to breaker close.
✓ Specific electrical ratings, response times, and signal input/output configurations are subject to confirmation based on the installed system — refer to the Woodward SPM-A product documentation for full technical parameters.
✓ Compatible with Woodward speed governors, AVR systems, and associated marine switchboard control panels, subject to system configuration confirmation.
✓ Designed for panel-mount installation within main switchboard or emergency switchboard enclosures in the engine control room or switchboard room.
✓ Replacement of this module should be carried out by qualified marine electrical engineers; settings and calibration may require recommissioning against the existing power management system.
Marine Applications
✓ Main switchboard generator synchronisation on cargo vessels, tankers, and bulk carriers.
✓ Emergency generator paralleling systems on passenger ships, RoPax ferries, and cruise vessels.
✓ Offshore platform supply vessels and anchor handling vessels with dynamic positioning power plants requiring precise load sharing.
✓ Naval auxiliaries and government vessels where reliable power changeover and synchronisation are operationally essential.
✓ Retrofit and upgrade of existing Woodward-based power management and control systems on ageing tonnage undergoing class renewal.
Why Marine Engineers Choose
The Woodward SPM-A is a recognised component in marine power management, valued for its integration with Woodward governor and control ecosystems, its reliability in demanding shipboard electrical environments, and the availability of OEM-level technical documentation and support — making it a preferred choice for like-for-like replacement on vessels with established Woodward installations.
Ideal For
Cargo ships, tankers, bulk carriers, container vessels, offshore support vessels, passenger ferries, cruise ships, dredgers, and any commercial or specialist vessel operating multi-generator power plants requiring automatic or semi-automatic synchronisation.
Technical Support & Compliance
Technical assistance is available to support remote troubleshooting, onboard diagnostics, testing, commissioning, and integration of this synchronizer module within existing marine control systems. Repair and retrofit guidance can also be provided, subject to confirmation of the specific system configuration. To confirm compatibility and ensure correct application, buyers are encouraged to share nameplate photographs, the full part number, panel or system drawings, the power management system model and software version, and vessel name or IMO number where relevant. All compatibility and suitability assessments are subject to confirmation based on the information provided.
