Applications

All‑electric fishing boat

6–8h operation, low noise, fuel saving

Coast Guard Vessel

Low‑speed silent tracking, low thermal signature, extended patrol endurance, tactical stealth.

Tour Boat

Silent, zero‑emission harbour manoeuvring, improved passenger comfort, access to protected waters.

Workboat hybrid

Reduce fuel consumption, extend range

Harbour tug

High thrust, short peak power

Leisure yachts

Replaces existing batteries, offering maintenance‑free convenience and longer time on the water.

Cruise

Zero‑emission berthing, silent comfort; hybrid cruising saves fuel.

Ferries

zero‑emission, silent harbour manoeuvring, hybrid for long range.

Merchant Vessel

Pure electric in port avoids fines; energy recovery at sea saves 15–25% fuel, improves rating.

Platform Workboat

Pure electric standby and approach – zero emissions, silent, reduced engine wear.

AID Aperla Large Cruise Ship ESS Retrofit

AID Aperla completed the retrofit in 2020 with 10MWh capacity, capable of short‑duration pure electric operation, achieving zero‑emission operations in ecologically sensitive areas and ports – setting an industry benchmark for large‑scale cruise ship storage retrofits.
