Who Are ALSEAMAR?
Based in Aix-en-Provence, France, ALSEAMAR designs, manufactures, operates and maintains naval and underwater products (subsea gliders, underwater vehicles for combat divers, underwater acoustic positioning systems, surface ships and submarine radiocommunication systems, deep-water syntactic foam buoyancy solutions.
ALSEAMAR are also a proud provider of numerous services such as glider data collection surveys, training and systems maintenance.
RS Aqua and ALSEAMAR
Back in 2020, we announced our exclusive partnership agreement with ALSEAMAR to bring their SEAEXPLORER Autonomous Underwater Vehicle to the UK and Ireland.
We are proud to support ALSEAMAR in bringing their product to market in the United Kingdom. The SEAEXPLORER ocean glider has the potential to open many research possibilities in the ocean science industry, below we are breaking down the opportunities that SEAEXPLORER can bring with its technology.
The ideal Autonomous Underwater Vehicle
This AUV is a very cost-effective solution for data collection as it reduces reliance on large vessels with high daily running costs; no surface supervision boat is required during the mission.
With a speed of up to 1kt, this rechargeable AUV has multiple navigation modes such as surveying, virtual mooring, drifting and bottoming and is idea for the below applications:
Application fields
- Marine science and environment
- Oil and gas
- Defence and security
Key features
- Unique wingless design
- No external moving parts
- Fast recharge time between missions
- High endurance
- Collects data in challenging conditions
- Data accessible through web-based platform
- External Li-ion battery recharging
- Two-way satellite communication
How does the SEAEXPLORER work?
By continually modifying its buoyancy, the SEAEXPLORER silently glides up and down in the water column. The altimeter in the nose detects and avoid the seabed, whilst changes to its battery pack orientation control its angle of motion.
The propeller system is mounted at the rear of the SEAEXPLORER and features a dual-propeller design, enabling precise heading control without the need for a rudder.
This innovative approach allows the glider to maintain a horizontal trajectory in the water, improving its efficiency and increasing the distance travelled per dive cycle. Designed for integration with the SEAEXPLORER family, the propeller system is fully compatible with both the Standard and Shallow variants, offering enhanced manoeuvrability for a wide range of autonomous underwater missions.
Software
Reliable and low maintenance, the SEAEXPLORER Opensource C++ firmware is easily configurable with missions being plotted through a web-platform, accessible from anywhere with a reliable internet connection.
GLIMPSE software
ALSEAMAR uses GLIMPSE software to collect real time data anytime, anywhere in the world. The simple, user-friendly interface allows customers to easily manage multiple gliders at sea.
Types of data collected
- Physical
- Chemical
- Biological
- Acoustic
*Depending on the sensors installed on the glider.
How to deploy the SEAEXPLORER
Showing remarkable endurance, The SEAEXPLORER is easy to operate and can be deployed by just a few individuals in coastal waters from a small vessel. With a deployment length of up to 127 days, or 2700km, the SEAEXPLORER can go the distance.
How to recover the SEAEXPLORER
Like it’s deployment, the SEAEXPLORER’s independent CPUs for navigation and payload control mean the glider is an operationally safe, reliable and low-maintenance platform when it comes to recovery.
Personalise for specific applications
This underwater glider can be equipped with a large variety of sensors, of which up to six can be fitted to one SEAEXPLORER, including:
- CTD (pumped or non-pumped)
- Dissolved Oxygen (Optode or Electrochemical)
- Chlorophyll / Turbidity / CDOM
- PAR
- ADCP
- Nitrates
- pCO2
- Echosounder
- Fluorometers options
- PAM
- Methane
- Hydrocarbons
- Turbulence
