Use of new high performance class-approved computer system will enable new features to be included into various zero emission solutions for ship & offshore applications.

Fukuoka, Japan – 21st January 2021 - As part of its ongoing product development program Eco Marine Power Co., Ltd. (EMP) announced today that it will incorporate the KEI-64S marine computer system into its zero emission solutions for shipping and offshore applications plus utilise the system architecture for other systems. These solutions include the patented EnergySail®, Aquarius Marine Solar Power and Aquarius Marine Renewable Energy (MRE).

The KEI-64S is a multifunctional computer system designed to be robust and be able to operate in temperatures up to 55°C. It incorporates a 1.33GHz dual core processor and has interface units that support numerous communication protocols including NMEA, MODBUS, USB2.0 and RS-232C. Connections to the ship’s LAN are also possible via Ethernet ports.

In cooperation with KEI System of Osaka, Japan, this new computer will become the core component of the EnergySail Automated Control System (ACS). This control system automatically manages the operation of each EnergySail so that they are positioned to be suit the prevailing weather conditions and lowered and stored as necessary. It also enables each sail to be optimized so that they provide a zero emission source of propulsion and power for ships.

In addition, the KEI-64S will replace the KEI-3240 computer as the main processor for the Aquarius Management & Automation System (MAS). Aquarius MAS is a cost effective monitoring, alarm handling and data logging platform suitable for a wide range of ships. The system can also monitor & log fuel consumption in real-time and calculate emissions (SOX, NOX, CO2). It will also be used as the management system for EMP’s marine solar power solution, be utilised as a data logger and can form part of a battery management system (BMS).
