ReFlow has launched a digital Lifecycle Emissions Assessment Tool designed to help shipowners evaluate decarbonisation strategies by simulating a vessel's complete environmental impact from production through operation.

The platform, developed with support from Danish Shipping and several Danish shipping companies, allows users to model different scenarios including alternative fuel types, technology upgrades, and energy-efficiency measures across a vessel's entire lifecycle.

"Data-driven green transition" is the goal of the tool, according to Rasmus Elsborg-Jensen, CEO of ReFlow. The company claims the standard model will enable shipowners to explore various decarbonisation pathways while balancing environmental and economic considerations.

The shipping industry faces the challenge of achieving climate-neutral operations by 2050, requiring companies to make complex decisions about fuel choices and technology investments.

Cecilie Damgaard Jensen, decarbonisation analyst at DFDS, highlighted the tool's potential for assessing upstream emissions from vessel production: "I believe the tool holds huge potential for having a simple way of estimating the upstream emissions from vessel production. We will be looking into it more when we look at new fuels especially, because the production side becomes more important."

The project began in 2023 with funding from the Danish Maritime Fund. Nina Porst, executive director of climate, environment, and security at Danish Shipping, said the organisation prioritised developing a tool covering the complete vessel lifecycle that would be operational and useful for members' decarbonisation processes.

ReFlow served as technical lead for the digital model development, while Danish Shipping acted as project facilitator and administrator.

The tool was developed in cooperation with A.P. Moller-Maersk, Navigator Gas, DFDS, Uni-Tankers, Torm, Cadeler, Svitzer, and ZITON.

The Danish Maritime Fund supported the project, with a full project report available through the fund's website.
