In 2023, the National University of Singapore partnered with Resinex to develop a custom-designed instrumental buoy for the innovative MESN (Marine Environmental Sensing Network) project, with the purpose of creating an advanced environmental monitoring network in Southeast Asian waters.
The data collected by the units is processed through the Ombak platform (which means “wave” in Malay), providing real-time access to the gathered information.
Measurements focus on crucial parameters for studying climate change and its impact on marine ecosystems, such as water quality, its acidification, oxygenation and nutrient presence.
This initiative promotes collaboration among various institutions to collect as much data as possible and strengthens the link between research centers and industry, with the goal of testing and validating innovative marine technologies.
For example, in 2024, these analyses enabled researchers to promptly detect a massive coral bleaching event during a major marine heatwave.

To meet these needs, Resinex designed a unique solution: a non-symmetrical modular buoy composed of six floating segments. The structure supports a tower topped with a marine beacon, self-powered and visible up to 4 nautical miles.
The dual mooring system ensures stability and position retention even in significant wave and current conditions.
This configuration minimizes oscillations and movements of the buoy, guaranteeing measurement accuracy and sensor protection. Thanks to this solution, the buoy can operate reliably for extended periods, maintaining consistent data quality.
Another significant innovation lies in the buoy’s superstructure, made of aluminum and designed to house a telescopic pole inside, capable of extending below the float and the counterweight, allowing the integration of devices without interference from the structure itself.
The inclusion of through-holes (moon pools) inside four of the six polyethylene floating segments proved essential, as it provides flexibility in choosing sensors (and therefore measurements) to install, opening up previously unthinkable research possibilities.
With its flexible and robust design, Resinex introduces a modular, high-performance solution for marine monitoring, capable of integrating multiple sensors under complex operating conditions. This innovation not only ensures reliable and continuous data collection but also offers the possibility to customize the configuration according to research needs.
