Equipped to Lead Underwater and on Land

We have our own fleet of vessels and specialised equipment designed for demanding operational environments, as well as a wide range of sensors and acquisition and analysis platforms.

Autonomous Bathymetric Survey at the Port of Avilés (Asturias)

Prosermar Ingeniería was commissioned to develop an autonomous bathymetric control system during the reclamation works at the Port of Avilés. The objective was to provide an unmanned solution for the precise monitoring of underwater earthworks, with particular focus on dredged volumes and the validation of executed geometries.

Main tasks carried out:

Development and integration of the SCOP system into the unmanned vessel BlueBoat, enabling autonomous navigation with programmed routes.
Daily surveys with the GeoSwath Plus multibeam echosounder to obtain high-resolution bathymetric maps of the reclamation area seabed.
Real-time positioning using Trimble RTK GPS with radio corrections and synchronised recording with motion sensors (MRU).
Mission configuration from the technical base onshore, with data transmission and remote control from a ground station.
Daily data processing and validation to compare with projected volumes and adjust the pace of site works.

Results:

Daily generation of bathymetric maps with a 0.25 × 0.25 m grid over the intervention areas.
Precise monitoring of dredged volumes and millimetre-level control of underwater reclamation progress.
Optimisation of site resources by reducing the need for manned vessels.

Added value:

This project demonstrates Prosermar’s capacity to integrate autonomous bathymetric systems with in-house software, providing technical monitoring solutions in complex port environments. The system’s operational autonomy increased safety, reduced costs, and enhanced traceability of the executed works.

Multibeam Bathymetric Survey in the Bellús and Beniarrés Reservoirs (Alicante)

The Júcar River Basin Authority commissioned Prosermar Ingeniería to carry out full bathymetric surveys in the Bellús and Beniarrés reservoirs, with the aim of updating their reservoir curves, calculating current volumes, and assessing sediment accumulation compared with previous campaigns.

Main tasks carried out:

Deployment of the Prosermar Siete vessel equipped with a GeoSwath Plus multibeam interferometric echosounder.
Comprehensive system calibration through alignment checks, sound velocity tests, and sensor height adjustments prior to surveying each reservoir.
Full water surface coverage with over 20% overlap to ensure the resolution and reliability of the models.
Synchronous recording with Trimble SPS751 RTK GPS, along with SVP sensors for sound velocity profiling.
Bathymetric processing with GS4 and generation of digital models using Global Mapper and MatLab.

Results:

Updated bathymetric curves at 0.5-metre intervals.
DTM (digital terrain model) in DWG, ASCII, and georeferenced KMZ formats for each reservoir.
Estimation of usable water volume and comparison with previous campaigns (capacity curves).
Delivery of technical reports and 3D visualisations for the Authority’s internal management.

Added value:

This project highlights Prosermar’s capability to undertake complex bathymetric studies in hard-to-access reservoirs, combining instrumental precision with advanced data processing. Compatibility with official cartography and GIS formats was key to its integration into hydraulic management systems.

Bathymetric and Geophysical Survey of the Mar Menor (Region of Murcia)

Prosermar Ingeniería collaborated with the Spanish Institute of Oceanography on a technical campaign in the Mar Menor aimed at the comprehensive study of the lagoon bed. The objective was to characterise the relief and sub-bottom structure using bathymetric and geophysical techniques, within the framework of an environmental study.

Main tasks carried out:

Bathymetric survey with an interferometric echosounder, achieving 100% bed coverage and a high-resolution seabed model.
Acquisition of reflection seismic data with a Geoacoustics profiler, enabling the identification of sedimentary layers, density levels, and structural changes.
Complementary side-scan sonar for acoustic reflectivity analysis and detection of surface morphologies.
Real-time positioning with Trimble 5700 RTK GPS and differential corrections via base station.
Data integration to produce thematic maps of the lagoon bed, with particular attention to areas of accumulation and nutrient transit.

Results:

Digital model of the Mar Menor seabed with a 0.5 × 0.5 m grid.
Seismic sections and stratigraphic interpretation identifying sediment accumulation zones.
Reflectivity and seabed texture maps useful for biological and environmental studies.
Technical support for researchers and deliverables in GIS and scientific formats.

Added value:

This project demonstrates Prosermar’s capacity to collaborate in complex scientific studies by combining hydrographic and geophysical techniques. The campaign contributed to environmental knowledge of the Mar Menor and served as a basis for future research and ecosystem management.

Seismic Profiling and Geophysical Survey in the Port of Ferrol (A Coruña)

The Port Authority of Ferrol commissioned Prosermar Ingeniería to carry out a geophysical study of the marine subsoil in areas near breakwater and reclamation works. The main objective was to characterise the stratigraphy of the seabed, detect rocky outcrops, and define the nature of the materials in areas designated for future expansion.

Main tasks carried out:

High-resolution seismic profiling with a Geoacoustics system, producing sub-bottom images with penetration up to 10 m and good vertical resolution.
Georeferenced positioning using Leica differential GPS with local corrections.
Processing and interpretation of seismic sections, identifying soft layers, stratigraphic boundaries, and hard levels.
Data georeferencing and generation of sediment distribution maps for civil works planning.

Results:

Interpreted seismic sections with identification of layers and rocky areas.
Geophysical maps showing sediment distribution and areas of limited penetration.
Technical report for the design of foundations, breakwaters, and potential underwater works.

Added value:

This study enabled design and execution decisions to be based on precise marine subsoil data, reducing technical and economic risks in port development. Prosermar demonstrated its expertise in integrating seismic systems within real operational environments.

Bathymetric and Topographic Survey in the Port of Tangier Med (Morocco)

During the initial expansion phase of the Port of Tangier Med, Prosermar Ingeniería was contracted to carry out bathymetric and topographic control of the maritime works. The objective was to obtain precise seabed profiles, monitor dredging progress, and ensure the correct execution of the port structures under construction.

Main tasks carried out:

Singlebeam bathymetric surveys in dredging and reclamation areas, at 200 kHz frequency and synchronised acquisition with RTK GPS.
Topographic support tasks onshore with a total station, georeferencing construction elements and setting out in quays and structures.
Monitoring of construction progress through periodic campaigns, comparing volumes and execution levels.
Generation of longitudinal and cross-sectional profiles of the seabed in the intervention areas.

Results:

Updated bathymetric models during the works, with sufficient accuracy for technical control and dredging validation.
Plan and elevation drawings showing the exact location of executed and planned elements.
Technical documentation delivered in DWG, DXF, and Excel formats for integration with project engineering.

Added value:

This project showcased Prosermar’s capability to operate in international environments with demanding technical standards, providing reliable solutions both on land and at sea, and working in direct coordination with engineering firms and contractors.
