Emergency Distribution Panels: Uninterrupted Power When It Matters Most

In marine environments, failure is not an option—especially during emergencies. That’s why Emergency Distribution Panels (EDPs) are a mandatory part of every vessel’s electrical infrastructure. At Serden Ship Supply Marine Electric & Electronics Ltd., we specialize in the design, manufacturing, installation, and commissioning of marine emergency power panels that comply with SOLAS, IMO, and class society standards.

Our EDPs ensure critical systems remain powered during blackouts, fires, machinery failures, or any unexpected power interruptions.

 What is an Emergency Distribution Panel?

An Emergency Distribution Panel is a dedicated electrical switchboard that distributes power from the emergency generator or battery banks to essential ship systems during main power failure. It operates independently of the main distribution system and supports:

• Emergency lighting

• Fire detection and alarm systems

• Emergency communication (radio, PA)

• Navigation and signaling systems

• Emergency pumps (bilge, fire, fuel)

• Watertight door controls

• Steering gear backup

• Battery chargers and emergency fans

It’s designed to automatically activate within 45 seconds after a blackout, per SOLAS regulations.

 Key Features of Our EDP Systems

Serden’s EDPs are designed to handle extreme environments and high-risk scenarios. Our panels typically include:

• Marine-rated enclosures (IP54–IP65)

• MCCBs, MCBs, fuses, contactors for protection

• Input selector switches for generator/battery/shore supply

• Voltage/frequency monitoring devices

• Built-in alarms for overloads or supply loss

• Emergency load shedding modules

• Lamp test and fault detection circuits

• Separate fire-retardant cable compartments

• Options for dual-input redundancy

 Integrated with Emergency Power Sources

Our EDPs are fully compatible with:

• Emergency diesel generators

• UPS and battery backup systems

• Shore power bypass with auto-transfer switches (ATS)

• Solar backup for critical systems (on hybrid vessels)

Each panel includes fail-safe logic and automatic/manual bypass functions to ensure continuity of power during system failures.

 Compliance with Maritime Safety Standards

All Serden EDPs are designed and tested in accordance with:

• SOLAS Chapter II-1 / Regulation 42 & 43

• IMO Resolution A.753(18)

• IEC 60092-504 (marine electrical systems)

• Classification societies: DNV, RINA, BV, LR, ABS, ClassNK

• Flag state requirements

We deliver panels with:

• FAT (Factory Acceptance Test) reports

• Type test certificates

• Cable schedules & wiring diagrams

• Operation and maintenance manuals

 Smart Monitoring & Alarms

Serden offers optional smart EDP solutions with:

• Digital HMI or touchscreen control

• Real-time voltage and load readouts

• Alarm logging for maintenance

• Remote status reporting to bridge or AMS

• Integration with Emergency Shutdown System (ESD)

We also provide redundant busbar designs to prevent single-point failures.

 Applications Across Vessel Types

Our EDPs are installed on:

• Oil tankers and LNG carriers

• Cruise ships and passenger ferries

• Cargo ships and Ro-Ro vessels

• Offshore support vessels

• Tugboats, fireboats, rescue boats

• Naval vessels and submarines

• Superyachts and expedition vessels

Each system is custom-engineered to the ship’s emergency load plan and operational priorities.

 Installation, Retrofit & Maintenance

Serden provides:

• Site survey and load analysis

• Engineering drawings and schematics

• Panel fabrication in-house

• Onboard wiring and installation

• Integration with existing emergency generator/UPS

• Load testing and commissioning

• Crew training and documentation

We also handle retrofit projects for aging vessels that need upgraded emergency systems to meet modern standards.
