2011 Aquarius Craft
The construction and development of a submersible calls for expertise in all aspects of engineering. A submersible operates in a very hostile environment under extreme pressure. The vehicle has to carry all the necessary equipment and consumables to maintain the well-being of the occupants for the planned mission time. The submersible is more akin to a manned space vehicle than to a ship, land vehicle or aircraft.
Through its dedicated approach to uncompromising design and the employment of recognized specialists in life support engineering, battery technology, underwater navigation/communication systems, electronic control systems and propulsion, SUBEO has the expertise and experience to construct submersibles to the requirements of its customers.
The latest computer-aided design techniques are employed in the design process, enabling the vehicle to be ‘built’ in the computer and tailored to the customer’s requirements.
