WOODWARD
PART NO.: 9907-175
LOAD SHARING MODULE
REV.: A
24 VOLT
161-0797 ECL1
CAGE: 31361
The Woodward 9907-175 is a 24-volt Load Sharing Module designed to control and balance the distribution of electrical load between parallel-connected generators in marine power management systems. As a core component within a vessel’s marine control system, it ensures that generating sets share the electrical load proportionally and stably, preventing overload on individual units and maintaining reliable power supply to critical onboard consumers. Accurate load sharing is essential for safe and efficient vessel operation, particularly during manoeuvring, port operations, or heavy electrical demand periods.
Key Features
✓ Functions as a load sharing controller, regulating active power distribution between generators operating in parallel to maintain balanced and stable electrical output.
✓ Operates on a 24-volt DC supply as specified in the original product data; additional electrical ratings and response characteristics are subject to confirmation based on system configuration.
✓ Manufactured by Woodward, a globally recognised supplier of power and energy control systems, with CAGE code 31361 confirming the original manufacturer’s identity for procurement and traceability purposes.
✓ Suitable for integration within Woodward-based governor and power management control architectures; compatibility with specific panels, controllers, or switchboard systems should be confirmed against vessel documentation and system drawings.
✓ Replacement or servicing of this module should be carried out by qualified marine electrical engineers; ensure the revision level (Rev A) and part number are verified against the installed system before ordering to confirm a direct fit.
Marine Applications
✓ Parallel generator management systems aboard merchant vessels, where multiple generating sets must share load equally during normal sea passage and port operations.
✓ Vessel power management panels on offshore support vessels, platform supply vessels, and anchor handling tugs where dynamic electrical loads demand precise load sharing control.
✓ Diesel-electric propulsion vessels and those with multiple generator configurations, where load imbalance between alternators presents a critical operational and safety risk.
✓ Engine control rooms and switchboard automation systems on tankers, bulk carriers, and container ships utilising Woodward governor and load control equipment.
✓ Retrofit and upgrade projects where ageing or failed load sharing modules within existing Woodward-based control systems require like-for-like replacement to restore full system functionality.
Why Marine Engineers Choose
Woodward load sharing modules are specified by marine engineers and electrical officers for their proven reliability in demanding shipboard environments, their compatibility within established Woodward control architectures, and the operational assurance they provide in maintaining balanced, stable power generation across parallel generator sets.
Ideal For
Merchant vessels, offshore support vessels, platform supply vessels, anchor handling tugs, tankers, bulk carriers, container ships, and any vessel operating parallel generator configurations with Woodward-based power management and governor control systems.
Technical Support & Compliance
Technical assistance is available to support troubleshooting, replacement planning, commissioning, and integration of this module within existing onboard control systems. Retrofit and upgrade enquiries are welcomed where existing Woodward load sharing equipment requires modernisation or like-for-like substitution. To confirm compatibility and suitability for your specific installation — subject to confirmation — buyers are advised to share the nameplate photograph, full part number and revision, system drawings or wiring diagrams, the model and version of the associated governor or power management controller, and vessel name, IMO number, and scope of work where applicable.
