Royston

engine i is a modular marine energy-management system developed by Royston Ltd, which combines hardware and software to monitor fuel flow, consumption, tank levels, bunker operations, emissions and vessel performance. The system enables ship owners and operators to gain real-time insights into engine and fuel usage (including speed, RPM, operational mode and more), deliver automated reporting and dashboards both on-board and ashore, optimise operational efficiency, reduce fuel and carbon costs, and comply with emissions regulations. Because it is compatible with multiple engine types (new-build or retrofit) and supports integration with on-board sensors, the system is used across a wide range of vessel types — from offshore vessels to tugs and dredgers — globally.
