Comments

The GIRONA 500 is a reconfigurable autonomous underwater vehicle (AUV) designed for a maximum operating depth of up to 500 m. The vehicle is composed of an aluminum frame which supports three torpedo-shaped hulls of 0.3 m in diameter and 1.5 m in length as well as other elements like the thrusters. This design offers a good hydrodynamic performance and a large space for housing the equipments while maintaining a compact size which allows operating the vehicle from small boats. The overall dimensions of the vehicle are 1 m in height, 1 m in width, 1.5 m in length and a weight of less than 200 Kg. The two upper hulls, which contain the flotation foam and the electronics housing, are positively buoyant, while the lower one contains the more heavy elements such as the batteries and the payload. This particular arrangement of the components separates the centre of gravity from the centre of buoyancy by about 11 cm, which is significantly more than found in a typical torpedo shape design. This provides the vehicle with passive stability in pitch and roll, making it suitable for tasks that will benefit from a steady platform such as interventions or imaging surveys.

Operational Experience: PANDORA is an EU FP7-ICT STREP research project between 5 universities across Europe in response to Challenge 2 of the Cognitive Systems and Robotics call. GIRONA 500 AUV will be used in Pandora to carry out two of the three demonstrations scheduled in the project. For the first demonstration, a water jet will be attached to GIRONA 500 to clean the chain of an anchor. In the second demonstration a manipulator will be connected to GIRONA 500 to turn the valves of an underwater panel.
