Description
WOODWARD
PART NO: 9907-175
LOAD SHARING MODULE
REV: B
161-0797 ECL05
24 VOLT
The Woodward 9907-175 Rev B is a 24V DC Load Sharing Module designed to manage and balance electrical load distribution between parallel-connected generators onboard vessels. As a core component within marine power management and control systems, it ensures stable frequency and load allocation across generating sets, preventing overload conditions and supporting efficient power plant operation. Reliable load sharing is fundamental to shipboard electrical safety and the uninterrupted supply of power to propulsion, navigation, and auxiliary systems.
Key Features
✓ Performs automatic load sharing between parallel generators, maintaining balanced power distribution and stable frequency under varying onboard demand conditions.
✓ Operates on a 24V DC supply as specified; full technical parameters including response characteristics and output ratings are subject to confirmation based on system configuration.
✓ Compatible with Woodward governor and power management architectures typical to marine generating plant installations; integration with specific panels or controllers should be confirmed against vessel documentation.
✓ Designed for installation within control panels or dedicated equipment rooms in the engine room environment; mounting and enclosure requirements depend on the local installation arrangement.
✓ When replacing or refitting this module, engineers should verify the revision level and associated ECL designation against existing system drawings to ensure full compatibility.
Marine Applications
✓ Parallel generator operation aboard merchant cargo vessels, tankers, and bulk carriers where multiple generating sets share the electrical busbar.
✓ Offshore support vessels and platform supply vessels requiring precise load management during dynamic positioning and heavy auxiliary demand.
✓ Passenger ferries and cruise vessels where uninterrupted and balanced power distribution is critical to hotel load and propulsion systems.
✓ Naval auxiliaries and government vessels utilising Woodward-based power management systems for generator synchronisation and load control.
✓ Engine room automation upgrade and retrofit projects where existing Woodward load sharing infrastructure requires module replacement or modernisation.
Why Marine Engineers Choose
Woodward load sharing modules are trusted in commercial and offshore marine applications for their reliable performance in generator paralleling systems. The 9907-175 Rev B supports stable power plant operation, reduces manual intervention, and helps protect generating sets from unbalanced loading — making it a preferred choice for chief engineers and electrical officers maintaining critical onboard power systems.
Ideal For
Merchant vessels, offshore support vessels, ferries, tankers, bulk carriers, naval auxiliaries, and any vessel class operating parallel generating sets with Woodward-based governor and power management control systems.
Technical Support & Compliance
Remote and onboard technical support is available to assist with troubleshooting, testing, commissioning, and integration of this module into existing marine power management systems. Retrofit and upgrade guidance can be provided subject to confirmation of the installed system configuration. Repair assessment may also be available depending on scope. To confirm compatibility and ensure correct supply, buyers are advised to share nameplate photographs, full part numbers, system model and version details, relevant wiring or system drawings, vessel name, IMO number, and a clear description of the intended scope — all compatibility confirmations are subject to review of the information provided.
