Ampereship GmbH

What Ampereship GmbH does

Ampereship GmbH is a German engineering company that designs, manufactures, and commissions fully electric passenger and car ferries for inland waterway transport. Founded in 2010 as a spin-off from shipbuilder Ostseestaal GmbH & Co. KG and operating under the Dutch Central Industry Group (CIG), the company is headquartered in Stralsund, Germany and serves public transport operators, municipalities, tourism companies, and harbor authorities across Europe. Its product portfolio spans standardized electric vessels (ASP-20 through ASP-300 for passenger ferries carrying 20–300 people; ASF-25, ASF-50, and ASF-150 for car ferries) as well as fully custom builds (Wunschschiff), with the first seagoing-capable vessel (Helgoland Dünenfähre) currently in construction.

The company's technical platform combines four modular technology layers: (1) lithium-polymer battery systems with proprietary Battery Management System, Lloyd's certification, IP65 rating, and modular 10.5 kWh blocks; (2) maritime-grade solar modules flush-integrated into deck/roof surfaces; (3) 360° rudder propeller drive systems up to 90 kW; and (4) Smart Cruise Control, an AI-driven energy management system that optimizes vessel speed, course, and power consumption in real time. The "Virtual Shipyard" (Virtuelle Werft) approach enables pre-equipped large modules that can be end-assembled without local shipyard infrastructure, with remote maintenance capabilities. As of 2025, the company has delivered 23+ joint projects with Ostseestaal, including the world's first fully electric car ferry (Sankta Maria II, 2017), with additional highlights including a 211.3 km world-record range achievement by MS Insel Mainau on Lake Constance in July 2025.

Ampereship generates revenue through three primary streams: turnkey new-build vessel sales (project-based, one-time), plug-and-play electrification retrofits converting existing diesel vessels to electric propulsion (professional services), and full-service lifecycle partnerships from concept through ongoing maintenance (managed services). Pricing is project-specific and not publicly disclosed. Go-to-market is enterprise sales-led, targeting public tenders and direct project inquiries across European inland waterways. The company operates without resellers or distribution partners, maintaining direct customer relationships throughout multi-year project lifecycles. Approximately 20 projects are reportedly in the active pipeline, spanning Southern Germany, Italy, and additional European sites.
