NYK Line and MTI Co., Ltd. (MTI), a member of the NYK Group, have partnered with UK-based Signol Limited to launch a trial aimed at driving decarbonisation through behavioural changes in onboard operations.
The initiative will analyse operational data from 33 vessels operated by the NYK Group using Signol’s digital platform, which applies behavioural science to influence day-to-day decision-making at sea.
Under the trial, seafarers will receive personalised goals, feedback, and operational insights intended to improve awareness of fuel consumption and emissions impacts, while maintaining safe ship operations.
The approach is designed to translate vessel performance data into actionable behavioural guidance for crew, highlighting how operational decisions influence fuel use and CO2 emissions.
The trial focuses on engine-related operational areas where crew input plays a direct role in efficiency outcomes, identifying opportunities to reduce unnecessary running time and optimise fuel use.
Signol’s system uses vessel-specific data to generate tailored recommendations delivered via email and a web-based application, linking individual actions to broader emissions performance.

The initiative reflects growing industry recognition that decarbonisation in shipping will require not only technical upgrades and alternative fuels, but also operational changes at the crew level.
NYK Group noted that while technical efficiency measures and fuel transition strategies are advancing in line with International Maritime Organization (IMO) greenhouse gas targets, operational decision-making remains a key lever for emissions reduction.
The company also highlighted that shipboard safety considerations often limit the extent to which efficiency measures can be applied manually, making structured behavioural tools a potential complement to existing optimisation methods.
The trial will run for approximately six months, with operational data collected before and after the programme used to assess its impact on fuel consumption and emissions performance.
Findings will also be shared with Columbia University, with the partners considering a joint academic publication involving NYK, MTI, Signol, and the university.
The partners said the project aims to demonstrate how crew engagement and behavioural insights can contribute to measurable emissions reductions, supporting the shipping industry’s transition towards lower-carbon operations.
