SAES drives innovation in marine sustainability with the SIMMBAD project

Publicado: 29/05/2026

SAES is strengthening its commitment to innovation and marine sustainability through the development of SIMMBAD (Smart Marine Monitoring System via Advanced Buoy), a technological solution for real time monitoring  of underwater  pollution,  validated at the Port of Cartagena. 

SAES was selected by the Regional Development Institute of the Region of Murcia (INFO) under the RETOS CAETRA 2024 call to address a key challenge: intelligent monitoring of underwater pollution in the port environment of Cartagena.

Within this framework, SAES has developed SIMMBAD, an innovative technological solution based on a smart buoy capable of monitoring acoustic emissions and chemical pollutants in real time within the marine environment.

The project addresses challenge CAETRA 2024-01, set by the Cartagena Port Authority, as part of the open innovation support programme in the fields of Defence, Security, Reconstruction and Development.

Advanced technology for marine protection 

The objective of the SIMMBAD project is to contribute to the protection of marine biodiversity and to support compliance with the European Marine Strategy Framework Directive, through the development and validation of a system capable of assessing environmental quality in port environments in real time.

As a result, an operational prototype has been developed, consisting of a buoy equipped with advanced sensors and a communication and data processing platform, enabling real-time visualisation and recording of data from shore.

Key project milestones include:

✅ Development of a functional prototype validated in a real-world environment (Port of Cartagena)

✅ Integration of specialised sensors, including a hydrophone and hydrocarbon detectors

✅ Data processing and transmission system

✅ Shore-based platform for visualisation and recording of environmental data

✅ Strategic collaboration with the Cartagena Port Authority, Unmanned Teknologies Applications, S.L (uTek) and Naval and Marine Technology Centre (CTN). 

Applied innovation: the Valkyria buoy 

The SIMMBAD system has been integrated into the Valkyria buoy, developed by Unmanned Technologies Applications, S.L. (uTek), which provides distinctive capabilities such as autonomous positioning without mooring, controlled mobility, and radiofrequency data transmission.

These features enable greater operational flexibility, allowing monitoring to be tailored to the specific needs of each port environment.

Validation in a real-world environment 

The project, which began in May 2025 and is scheduled for completion in May 2026, has already successfully passed key development and laboratory validation phases.

Testing carried out at the Port of Cartagena has confirmed the system’s operability under real conditions, including sensor integration, data transmission, and the performance of the control software developed by CTN, which incorporates real-time environmental and positioning data provided by the buoy.

Commitment to innovation and sustainability 

This project reinforces SAES’s position in the development of advanced technological solutions for the marine sector, combining innovation, public-private collaboration, and direct impact on sustainability.

In the words of Javier Mármol, President of SAES: “SIMMBAD is a clear example of how technological innovation can be harnessed to support sustainability and the protection of the marine environment. This project reinforces our commitment to developing advanced solutions that deliver real value to strategic infrastructures such as ports, contributing to more efficient and responsible environmental management.”

At a time when environmental monitoring is becoming increasingly critical, initiatives such as SIMMBAD strengthen SAES’s role as a key player in marine technology and environmental protection, delivering solutions that support more sustainable port management.
