Aquarius brochure
Subeo Ltd has developed the Aquarius, a 3-person submersible vehicle, building on the successful design of its predecessor, Gemini. The Aquarius incorporates advanced technology, particularly in its propulsion and energy systems.
Specifications
The Aquarius features a sealed nickel sodium battery, which is maintenance-free and safer than traditional lead acid batteries. It is powered by an integrated thruster system, which is compact and efficient, eliminating the need for water seals and complex gearboxes. The vehicle's monocoque hull construction with integral buoyancy tanks ensures a streamlined and lightweight design.
Life Support and Control Systems
The Aquarius is equipped with a fully integrated life support system, maintaining optimal cabin comfort and air quality for up to 74 hours. It is piloted using a joystick with a touch screen display for operational and life support values, allowing any occupant to pilot the craft.
Performance
The Aquarius can operate at depths of 50M to 100M and reach a maximum speed of 7 knots. It is designed under the classing authority of DNV and is ideal for underwater exploration and scientific observation.
Testing and Evaluation
A scale model of the Aquarius underwent dynamic assessment at IFREMER's Water Circulation Tank, demonstrating a low drag coefficient and confirming its speed capabilities with a 20kw thruster system.
Integrated Thrusters
The Integrated Thrusters provide high symmetrical thrust and are available in various sizes, suitable for submersibles, ROVs, AUVs, and other marine applications. They eliminate mechanical hull penetrations and optimize space.
Advantages of Zebra Batteries
The sodium/nickel chloride (Zebra) batteries offer zero maintenance, high energy density, and long life, with demonstrated durability over 12 years and more than 4000 charge/discharge cycles. They are safe, robust, and provide accurate state of charge monitoring.
Conclusion
The Aquarius is a state-of-the-art submersible vehicle designed for stability and efficiency in underwater exploration, making it suitable for both recreational and commercial use in areas with excellent underwater visibility.
Catalog excerpts
Subeo Ltd has now evaluated its 2-man concept vehicle Gemini and after extensive testing and market research has now developed its design for its 3-person production craft Aquarius. Aquarius will build on the very successful design of the Gemini vehicle, but will include the very latest technology in relation to its main propulsion systems. The heart of any submersible is its energy source, traditionally small submersibles and military submarines have used lead acid batteries. These batteries give off explosive gas when charging which in the sealed space of a submersible can result in potential explosion if the gas is not monitored and vented. The lead acid battery also requires considerable maintenance. Aquarius will use the sealed nickle sodium battery, which is totally sealed and maintenance free. Aquarius will be powered by an integrated thruster system. This new development in propellor power produces a very small unit without water seals or expensive and complicated Aquarius will use a monocoque hull construction with integral buoyancy tanks making a streamlined and maintenance free craft. This type of construction enables the craft to be manufactured in a relatively short time and reduces Aquarius will use the latest technology to monitor and control the craft but still maintain all the manual safety systems designed and built into the concept vehicle. Aquarius' life support systems and comfort cooling/heating are part of a fully integrated system maintaining the cabin at an ideal level of comfort and air quality. Its life support consumables will be sufficient for a normal mission time of 2 hours plus a further 72 hours required Aquarius is piloted by one joystick with all the operating and life support values displayed on a touch screen. Provision is made for all occupants to pilot the craft. Aquarius will have an operating depth of 50M to 100M and a maximum speed of 7 knots. Aquarius is designed and manufactured under the classing authority Aquarius is the ideal vehicle for underwater exploration and scientific observation, and with its multi-thruster system is a very stable underwater, filming and observation vehicle. Areas such as the Red Sea where underwater visibility and marine life are excellent provide ideal venues for investment, recreational and commercial use of this vehicle.

The scale model of Aquarius has undergone dynamic assessment at IFREMERs (world renowned French Marine Institute) Water Circulation Tank in Boulogne. The results from this testing indicate a very low drag co-efficient, giving a possible maximum speed of 7 knots with its 20kw thruster system. IntegratedThrusters (TM) are a perfectly matched combination of thruster and electric drive, providing high symmetrical thrust from a very small package. Integrating the direct drive motor into the thrust duct maximises its torque and efficiency while leaving water flow unobstructed. Different sizes are available...
