Eco Marine Power Co.

What Eco Marine Power Co. does

Eco Marine Power Co., Ltd. is a Fukuoka, Japan-based marine technology company founded in July 2010 by Ohori Capital Pty. Ltd. that designs and supplies renewable energy and sail-assisted propulsion solutions for commercial ships. Its core platform is the patented Aquarius MRE (Marine Renewable Energy) system, which integrates rigid sails (EnergySail), marine-grade solar panels, energy storage modules, and a computer control system that automatically positions the sails to prevailing weather conditions. Around this it bundles the Aquarius Management & Automation System (Aquarius MAS) - a class-approved marine computer built on the KEI 3240 Data Logger - which performs data logging, alarm management, fuel-consumption monitoring, and emissions calculation for vessels.

The company monetizes through three revenue streams: hardware sales of its own and partner-supplied products (Aquarius MRE, EnergySail, Aquarius Marine Solar Power, SurfGate IoT gateway, Furukawa Battery storage, NittoSeiko fuel flow meters); engineering, consulting, and design services for newbuild and retrofit projects; and licensing of patented technologies such as Aquarius MRE, EnergySail, and ship-design concepts (Aquarius Eco Ship, Aquarius Eco Handymax, Tonbo, Medaka) to shipbuilders and maritime technology firms. It serves ocean-going vessel operators, passenger ferry and cruise operators, shipbuilders and naval architects, and offshore/maritime operations including unmanned surface vessel applications, with support offices in Singapore, Vancouver, and Athens complementing its Fukuoka headquarters and a network of strategic technology and channel partners spanning Japan, the UAE, Singapore, Greece, and other regions.

Eco Marine Power does not manufacture hardware directly; it operates as a design and systems-integration company whose products are built, certified, and deployed through partners such as Furukawa Battery, KEI System, Teramoto Iron Works, Aries Marine, and Zeaborn Ship Management. Its Aquarius Innovation Forum coordinates shipowners (Star Bulk, ADNOC L&S, Ardmore Shipping, Neptune Lines), technology firms, and channel partners around joint evaluation projects, which functions as the company's primary go-to-market vehicle alongside direct enterprise engagement.
