Previous issue date: 2014-10-31 / 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. / Devido ? procura por novas fronteiras explorat?rias, uma grande variedade de equipamentos para amostragem geol?gica vem sendo desenvolvidos, em especial para ambientes marinhos com profundidades superiores a 300 metros. A manuten??o das condi??es in situ destes ambientes, notadamente a press?o, conferem qualidade ao processo de amostragem uma vez que evita a perda de elementos da amostra durante a recupera??o, especialmente gases. Neste contexto o dispositivo desenvolvido nesta disserta??o tem o prop?sito de coletar fluidos, em especial gases, de forma automatizada em ambientes subaqu?ticos em profundidades de at? 3000 metros e mant?-los nas condi??es de press?o da coleta. O dispositivo ? programado na superf?cie, sendo necess?rio transport?-lo at? o local de trabalho, com aux?lio de um ve?culo submarino de opera??o remota (ROV) de inspe??o, por exemplo. Al?m da valida??o em laborat?rio, o dispositivo proposto foi tamb?m avaliado em condi??es reais de mar. Por n?o existir equipamento igual ao desenvolvido nesta disserta??o, o mesmo foi patenteado.
