Marindows Co,Ltd.

Marindows Co., Ltd. is a Japanese firm established in March 2021 to drive the digital transformation of the maritime industry. The company originated as a spin-off from e5 Lab, a joint venture founded by Asahi Tanker, Exeno Yamamizu, Mitsui O.S.K. Lines, and Mitsubishi Corporation to promote electric vessels. Headed by President and CEO Yasumasa Suetsugu, Marindows aims to address critical industry challenges such as decarbonization, crew shortages, and safety through its integrated digital platform.

The core of Marindows' offering is its open digital platform, a marine operating system designed to connect onboard edge computing with cloud services and shore-based applications. This platform facilitates the use of various applications that support real-time ship-to-shore communications, a capability enhanced by the expected launch of widespread maritime broadband. The business model appears to be centered on providing this platform and a suite of related services to shipowners, shipping companies, and other personnel in the marine industry. The company has secured funding from notable investors including Mitsubishi Heavy Industries, Wärtsilä, Softbank, and Sumitomo Mitsui Finance and Leasing, which will be used for business development, technology improvements, and recruitment.

Marindows is developing several specific services to be rolled out. These include a work support terminal for crew members to manage tasks and working hours, a low-cost, network-connected drive recorder and portable electronic chart to enhance vessel safety, and a service to improve crew health through remote medical consultations and digital health logs. A significant project is the development of a next-generation zero-emission container ship in partnership with Imoto Lines. This vessel will feature a hybrid power system using exchangeable container batteries, onboard batteries, and generators, aiming for complete zero emissions throughout its lifecycle. The project, supported by Japan's Ministry of the Environment, focuses on standardization and modularization to reduce operating costs and improve efficiency, allowing for operation with fewer crew members.
