Ferry Electric Propulsion Retrofit

Pain Point

A coastal city operated a diesel‑powered ferry on a frequent harbour route. Noise and black smoke generated multiple complaints from shoreline residents. Fuel costs were rising, and the government was about to enforce stricter emission limits. The aging engine also incurred high maintenance costs and operational delays.

Solution

We supplied a full electric propulsion system for the ferry, including:

• LanghESS‑S1 modular battery system (capacity tailored to route distance)

• High‑efficiency permanent magnet synchronous motor

• Smart motor controller

• Shore‑side fast charger

The modular system recharges quickly during overnight or off‑service hours, with a single charge covering all daily return trips. The retrofit was completed during a scheduled shipyard stay, causing zero disruption to normal operations.

Value Delivered

• Zero emissions & low noise – No black smoke, no engine roar. Shoreline complaints dropped to zero, improving community relations.

• Drastically lower operating costs – Electricity costs are far below diesel, and engine maintenance expenses are eliminated.

• Higher reliability – Simpler electric drive means fewer failure points, improving on‑time performance.

• Regulatory compliance – Met new emission rules ahead of schedule, avoiding fines and service interruptions.

• Better passenger experience – Quiet, smooth rides have increased passenger satisfaction and load factor.
