Planning guide01
Ferry electrification starts with the operating plan
Route schedules, charging windows, and terminal readiness belong in the same conversation.
SECTOR 04 / VESSELS, TERMINALS & POWER
Marine Electrification.
A battery, a charging system, and a terminal do not become an operating service until their assumptions agree.

Shore power planning: vessel, berth & utility interfaces
Scope a shore power project by clarifying onboard loads, berth arrangements, utility requirements, operating windows, and ownership.
Separate three different conversations
Vessel electrification concerns propulsion and onboard energy. Shore power supplies a vessel while berthed. High-power charging replenishes onboard energy within an operating window. A project can involve more than one, but they should not be treated as interchangeable requirements.
Begin with the service to be delivered. Map route conditions, turnaround time, layover windows, berth availability, and maintenance access. Qualified vessel, electrical, and utility specialists can evaluate technical requirements against that common operating brief.
The dependencies to resolve before a specification
| Interface | Input to establish | Owner to identify |
|---|---|---|
| Schedule → vessel | Energy use and operating assumptions | Vessel technical team |
| Vessel → berth | Charging window and connection arrangement | Vessel and terminal teams together |
| Terminal → utility | Supply needs, connection process, lead time | Utility and shoreside electrical team |
| New equipment → operation | Training, support, maintenance, transition | Operating owner and suppliers |
Use real programs as a map, not a promise
Washington State Ferries describes its electrification work as a combination of new vessels, terminal infrastructure, and charging systems. That is a useful way to understand project dependencies. Its scale, schedule, and funding are specific to that program.
A study for another route needs its own assumptions, technical work, costs, and implementation sequence. Our planning guides explain what to ask for before turning a concept into a procurement package.
Questions buyers ask
Is shore power the same as ferry charging?
Not necessarily. Shore power can supply onboard loads while a vessel is berthed. Propulsion charging replenishes stored energy for vessel operation. The project brief must identify the loads, operating window, and interfaces involved.
Can an electrification study be completed before utility discussions?
Early screening can begin, but assumptions about supply capacity, connection works, and lead times need to be tested with the relevant utility and electrical specialists before committing to delivery dates or equipment requirements.
