The search for new exploratory frontiers has led to the development of a wide variety of geological sampling equipment, especially for marine environments with water depths greater than 300 meters. Maintaining the in situ conditions of these environments, particularly the pressure, provides quality to the sampling process as it prevents loss of sample elements, especially gases, during the retrieval process. In this context the device developed for this research aimed to collect fluids, particularly gases, in an automated manner from deep-water environments at depths up to 3000 meters and to maintain them under the same pressure conditions as when collected. The device is programmed at the surface and subsequently transported to the collection site, for example, with the aid of an underwater inspection remotely operated vehicle (ROV). In addition to laboratory validation, the proposed device was also tested under real sea conditions. No equivalent equipment to the device developed in this dissertation exists and it was therefore patented.
