Q2 – 2024
Spotlight: The Spanish Army selects the ROV Tortuga XP4 for its S&R missions, featuring a 5-function hydraulic arm!
Following a highly competitive international tender, Subsea Tech and its Spanish partner Casco Antiguo won the contract by offering a ROV Tortuga XP4 (4 vertical thrusters with pitch and roll control), equipped with various sensors and tools including a 5-function hydraulic arm, a Gemini multibeam sonar, an Imenco PTZ camera, a Subsea Tech 3-finger gripper, and an AAE Easytrack USBL. A true integration challenge that increased the Tortuga’s weight from 45 kg to 98 kg!
Delivered last May, the Tortuga XP4 provides unique underwater inspection and manipulation capabilities for an ROV of this size, even in low visibility and strong current conditions. The ROV will be used by the Spanish Army for Search & Rescue missions in inland waters. After the French, Portuguese, and Indonesian Navies, this marks the fourth success in less than a year with armed forces for the Tortuga ROV.

Subsea Tech continues underwater photogrammetric surveys…
February 2024
With its specially designed Mini TORTUGA XP4, equipped with the IVM Hydro 300 sensor, Subsea Tech seems to have convinced several clients of the exceptional submillimetric 3D modeling results obtained on pipes, cofferdam grooves, dock doors, and trash racks. Interventions are multiplying, and it is likely just the beginning, as photogrammetry brings a true revolution in data quality, especially for the inspection of complex structures on submerged infrastructure.
The aquatic drone Catarob in action at Parc Astérix!
March 2024
Subsea Tech conducted a very original bathymetric operation on the lake at Parc Astérix in the Paris region, made possible thanks to the compactness of its Catarob drone and the high resolution of its Norbit WBMS sonar. The survey allowed for the estimation of the sedimentation in the basin in preparation for improvement works planned before the 2024 season.
The Lantana drone inspects stormwater networks
June 2024
Marseille, Bordeaux, Paris, Lyon… the Lantana drone continues its tour of France’s stormwater networks. Conceptualized and developed by Subsea Tech nearly 10 years ago, this drone can simultaneously inspect EP structures both above and below the water surface. It combines video and acoustic imaging, laser profiles, and sonar, significantly reducing inspection time and thus cost.
SUBSEE+: Underwater image processing accessible to all
Eager to provide an efficient and affordable underwater image processing solution, we decided to develop our own image processing software for turbid environments in-house. Compatible with all types of digital cameras and usable on ROVs or diver cameras, it runs on Windows, in real-time or post-processing, allowing for the enhancement of archive images as well. Its advanced yet intuitive features allow for optimized processing based on environmental conditions. And all this at an unbeatable price! Feel free to request a trial version, it’s free!
New Recruit
We are pleased to welcome Thomas Thouveny, our new mechanical engineer, who joined our engineering team last April. After gaining initial experience in the design and production of test benches, Thomas decided to venture into the world of marine and underwater drones. He is already actively working on our European project SeaClear 2.0 and our new inflatable USV concept CatRiver. We wish him a warm welcome!
Our Commitments to the Planet!
Last May, we partnered with the association MerTerre as a field patron partner. We are now actively participating in their efforts to collect, count, and classify waste on beaches as well as their awareness campaigns. This sponsorship naturally aligns with our developments related to environmental protection such as the SeaClear 2.0 project.
A first cleanup operation was carried out by the Subsea Tech team at Anse de la Maronnaise, in Marseille at the beginning of June, followed by a sponsors’ evening at the Palais des Congrès on June 3rd to help the association raise funds and attract volunteers.
