- The spread of electric propulsion vessels in the future will reduce CO 2 emissions and reduce the workload of seafarers.
- Expected to maintain and improve system quality by utilizing feedback based on actual navigation of electric propulsion vessels.

E5 Lab Co., Ltd. and Mitsubishi Shipbuilding Co., Ltd. , A biomass fuel carrier with a total ton of 499 tons built by Honda Heavy Industries, Ltd. to design the standard hybrid electric propulsion ship "ROBOSHIP" that both companies aim to spread as the future image of ships. We have agreed to provide it to (hereinafter referred to as "the ship"). With the spread of "ROBOSHIP" in the future, it is expected that CO 2 emissions in the coastal shipping industry will be reduced, and the workload of seafarers will be reduced.

"ROBOSHIP" uses a standard system that packages hardware related to electrical propulsion such as propellers, motors, switchboards, storage batteries, and generators, and software that controls them safely and efficiently, with a total ton of 749 tons. Covers up to freighters. It does not have a conventional diesel main engine that requires fossil fuels, but drives a propulsion motor with a hybrid of a large-capacity storage battery and a generator, and adopts a high-performance twin skeg hull made by Mitsubishi Shipbuilding to increase propulsion horsepower by 20% or more compared to conventional ships. By reducing this, we will reduce CO 2 emissions during navigation and realize CO 2- free navigation during operations at ports such as cargo handling, takeoff and landing, and port entry / exit . By switching the fuel for generators to environmentally friendly fuels such as LNG (liquefied natural gas), hydrogen, ammonia, biofuels, and synthetic fuels, it is possible to make all operations, including navigation, CO 2- free.

In addition, there are merits such as improvement of inboard comfort by reducing noise and vibration, reduction of complicated diesel main engine maintenance by engineers with advanced experience and knowledge, and reduction of takeoff and landing operation load by improving ship maneuverability. Achieves load reduction. Furthermore, in the future, we will realize low cost by mass-building vessels equipped with the standardized system, and promote the spread of electric propulsion vessels. As it becomes more widespread, it will be possible to accumulate feedback based on actual navigation, and it is expected that system quality will be maintained and improved.

This ship will be built by Honda Heavy Industries for Asahi Tanker Co., Ltd. After completion and delivery in April 2023, we plan to engage in biomass transportation for Aioi Bioenergy Co., Ltd. Equipped with the Marindows platform developed by Marindows, the vessel will contribute to the digital transformation (DX) of the coastal shipping industry with the power of communication and digital.

e5 Lab is a solution provider for the shipping industry co-founded by a total of four shipping companies and trading companies for the purpose of electrical propulsion and digitization of ships. We aim to realize environmental conservation. In March 2021, we established "Marindows Co., Ltd.", a new company that aims to improve the working environment of crew members by providing a marine digital platform.

On the other hand, in the growth strategy "Ocean Future Stream" that Mitsubishi Shipbuilding is aiming for, "sea decarbonization society" by renewable energy and carbon cycle, "ocean space effective utilization society" by autonomy and electrification are drawn, and innovation related to the sea. We are advocating the realization of "wisdom" and its "shape". By developing the company's maritime-related technology accumulated by the Mitsubishi Heavy Industries Group and the comprehensive technology of Mitsubishi Heavy Industries, and providing it as a marine system integrator, we aim to solve the problems faced by customers and society.

e5 Lab and Mitsubishi Shipbuilding will continue to be responsible for value co-creation with stakeholders who place importance on ESG (environment, society, governance) with the aim of becoming a solution provider that works to solve the problems of the shipping industry.
