What MESURIS does

MESURIS Sarl is a French SARL founded in 1993 by Alain Mouquet, headquartered in Saint-Philibert (Brittany), that designs, manufactures, and operates proprietary multibeam bathymetric survey systems and real-time 3D construction-monitoring technology for maritime and coastal works. Its platform combines six registered product lines: SURVEX (a road-transportable mobile hydrographic survey vessel with permanently calibrated multibeam sensors), GEOSUB 3D (a crane-suspended multibeam unit for mapping without a conventional survey boat), POSIBLOC (real-time 3D topographical monitoring and guidance for concrete armour-unit placement on breakwaters using embedded BLOCKSfit software), TOPOMETRYX HR (a multibeam-laser scanner for simultaneous above- and below-water mapping), BATHYRELIEF (an interactive 3D digital terrain-model viewer), and BLOCKSfit (point-cloud analysis software using a deep-learning algorithm for automatic armour-unit detection at up to 1,100 blocks/hour). The company also holds distribution rights for complementary hardware and software (TELEDYNE RESON, QPS, MSI, GENERAL ACOUSTICS, TERIA) and integrates these into turn-key hydrographic systems.

The firm earns revenue across four streams: (i) professional multibeam bathymetric survey services using the SURVEX fleet (300+ days/yr of data processing, 150+ days/yr of survey); (ii) sale and integration of hydrographic, positioning, inertial, and laser-scanner hardware (proprietary products plus third-party OEM resale); (iii) short- or long-term leasing of POSIBLOC and GEOSUB 3D systems with optional operator and data-processing support; and (iv) licensing of BLOCKSfit software for as-built 3D reconstruction. Pricing is quote-based per project or per item and not publicly disclosed. Sales motion is direct enterprise field sales targeting major French accounts (ports, government agencies such as Voies Navigables de France) plus international maritime construction firms; export development started in 2008 and now represents nearly half of revenue. MESURIS serves four primary customer segments: maritime construction contractors (Bouygues Travaux Publics, Daewoo E&C), port authorities and government hydrographic agencies (SHOM, VNF), offshore wind developers (Les Éoliennes en Mer Services, Louis Dreyfus Travocéan), and hydrographic service companies purchasing integrated systems. Operations span France, Réunion, Monaco (wholly-owned subsidiaries since 2014 and 2017 respectively), and project-based activity across Europe, the Middle East (notably Iraq), Asia, and South America.

Product overview

MESURIS offers a portfolio of proprietary marine technology products centered on multibeam bathymetric survey and real-time construction monitoring systems. The core product line includes SURVEX™ (mobile hydrographic survey vessels), GEOSUB 3D™ (crane-suspended underwater mapping system), POSIBLOC™ (real-time block placement guidance), TOPOMETRYX™ HR (above-water laser scanning), and BLOCKSfit™ (3D model reconstruction software). BATHYRELIEF™ provides the visualization layer for combined data. The company also distributes complementary hardware (TELEDYNE RESON, GENERAL ACOUSTICS) and software (QPS suite) and provides associated survey, inspection, and data processing services. The offering is a platform-plus-modules architecture where BLOCKSfit software serves as the unified processing and visualization engine for both POSIBLOC and GEOSUB 3D systems.

Products and services

• POSIBLOC™ Real-time 3D topographical monitoring system that guides accurate placement of concrete armour units (ACCROPODE, ECOPODE, CORE-LOC, Xbloc) on breakwaters and seawalls. Uses no camera or sonar; equips cable cranes and excavators for single-layer armouring construction, replacing weather-dependent diving inspections with centimetre-accurate, day/night, all-weather control.
• GEOSUB 3D™ Suspended mobile multibeam bathymetric unit designed to be operated from a crane hook rather than a conventional survey vessel. Provides 160° acoustic coverage, point density up to 1000 points/m², and centimetre RTK accuracy for high-resolution underwater mapping in shallow water or inaccessible zones such as breakwater faces and harbour construction sites.
• BLOCKSfit™ Software package that computes positions and orientations of armour units (Accropode, Core-Loc, Xbloc, etc.) from XYZ point cloud data obtained via multibeam survey or other point cloud sources. Uses a deep-learning algorithm for automatic block detection at up to 1100 blocks/hour with detection in approximately 10 ms per block; supports DXF, OBJ, PLY, and STL outputs and serves as the unified processing engine for POSIBLOC and GEOSUB 3D data.
• SURVEX™ Mobile hydrographic vessel concept delivered as road-transportable aluminium workboats (6.80–9.10 m) with fully calibrated permanent sensors. Provides ultra-low draft (0.73–0.83 m), 210° swath coverage, and is operational within one hour of arrival on site for shallow-water high-resolution multibeam surveys.
• TOPOMETRYX™ HR 3D multibeam laser scanner system that maps above-water structures simultaneously with multibeam sonar underwater mapping, fusing topographic and bathymetric data in a single pass. Provides resolution up to 1000 points/m² for coastal topography and as-built documentation of coastal structures.
• BATHYRELIEF™ Interactive 3D digital terrain model that fuses bathymetric, laser scanner, construction plan, and aerial imagery data into a single visualization layer for seabed and coastal structure representation.
• Multibeam Bathymetric Survey Services High-resolution 3D seafloor mapping and seabed cartography services for maritime, coastal, and riverine environments using SURVEX mobile hydrographic vessels. Performed across France (metropolitan and Corsica) and internationally, with over 150 days of survey and 300+ days of data processing per year.
• Survey Inspection Services Structural inspection services for quays, bridges, breakwaters, and natural or artificial rock installations, including volume computation and density control.
• Data Processing and Volume Computation Processing of bathymetric data with volume calculations, isobath generation, and cross-section analysis delivered as a standalone service for clients who already have survey data.
• Electronic Systems Integration for Marine Applications Integration of hydrographic, positioning, inertial, sonar, and navigation systems onto marine vessels and equipment, including calibration and technical support for hydrographic service companies and engineering firms.
• TELEDYNE RESON Equipment Distribution Sale and integration of TELEDYNE RESON multibeam and single-beam echo sounders (including SeaBat 7125 and T51-R), inertial measurement units, hydrophones, and ROV/AUV integration solutions distributed by MESURIS to French hydrographic clients.
• QPS Software Suite (QINSy, Qimera, Fledermaus, QASTOR) Distribution Distribution of QPS hydrographic software solutions in France, providing acquisition, analysis, and 3D visualization tools for bathymetric data processing, multibeam survey operations, and marine construction applications, with French-language training and support.
