Ocean-going ROBOSHIP Ver. 1.0
e5 Lab Announces Concept for Large Electric-powered Bulk Carrier~ A World 1st: Moving Swiftly toward Zero Emissions in Ocean Shipping with Electric Vessels~

TOKYO—e5 Lab, Inc. today announced the completion of the concept model for the world’s firstlarge electric-powered bulk carrier. The company aims to realize sustainable ocean shipping industry
with zero emission electric-powered vessels.
e5 Lab positions the vessel as the basic type of “Ocean-going ROBOSHIP Ver. 1.0.”
As an electric-powered vessel promotion strategy aimed at establishing a decarbonized society, e5
Lab will offer electric-powered vessels featuring the world’s most advanced electric propulsion
systems, at the most competitive price in the global market.
In this development project, e5 Lab will also realize zero emissions in harbors and ports, withstrategic partners in Japan and overseas including Mitsubishi Shipbuilding Co., Ltd.(*)

Background: Development of large-size ocean-going electric-powered vessel

Ship × Sustainability × Innovation“What kind of vessel is most in demand around the world?”
üA vessel uncompromisingly committed to “safety”
üA vessel uncompromisingly committed to “the environment”
üA vessel uncompromisingly committed to “evolution”
e5 Lab will realize ocean-going ROBOSHIP Ver. 1.0, max class. starting with an 86,000DWT bulk
carrier in the Kamsar
Along with its partners, e5 Lab will accelerate the achievement of a sustainable society by expanding
its lineup of ocean-going electric-powered vessels to help them gain wider acceptance in themarketplace.
The company’s goal is to start “a revolution that creates the next century of ocean shipping” fromJapan to the nations around the world.

News Release

Basic type of “ocean-going ROBOSHIP Ver. 1.0.”
The vessel will achieve the same levels of cruising range and speed as conventional vessels inservice, while achieving zero-emission operation in harbor and port, by using not only large-capacity
rechargeable batteries, but also with diesel generators, based on the electric-powered vessel
powertrain platform, which was designed and planned by e5 Lab.
It will achieve higher energy efficiency than current vessels by leveraging e5 Lab’s knowledge andexperience, as well as its partners’ world-leading technology, such as artificial intelligence (AI) andthe most efficient electric devices (DC grid, PM motors, and so on).
ROBOSHIP Ver. 1.0. will significantly reduce the workload of seafarers, while reducing maintenancecosts and ensuring trouble-free operation, thanks to all-electric propulsion, which drives the motorusing only electricity.
In addition, electric-powered vessels are easy to equip with double-shaft propellers, which enhancesafety by improving operability, and its wide-breadth configuration will increase the cargo capacity.
The ROBOSHIP continually evolves from the aspects of both safety and efficiency, based on the EV
Platform and the Digital Platform “Marindows” ※ .” ※ Patent pending
