Retrieval of subsea production and processing equipment

RETRIEVAL OF SUBSEA PRODUCTION AND PROCESSING Generally, the present disclosure is directed to systems that may be used to facilitate the retrieval and/or replacement of production and/or processing equipment that may be used for subsea oil and gas operations. In one illustrative embodiment, a system is disclosed that includes, among other things, subsea equipment (100) that is adapted to contain a first fluid while operating in a subsea environment (160), and an accumulator device (120a, 120b, 120c, 120d, 120e) that is in fluid communication with the subsea equipment (100), wherein a pressure boundary of the accumulator device (120a, 120b, 120c, 120d, 120e) is adapted to move in response to a pressure change on the subsea equipment (100) as the subsea equipment (100) is raised from the subsea environment (160). 120 101 120 102 110 108 111a 170 108 103 10 10b 10503 |10912 105 15 106 103 110 110 103 04 6 0 105 15105 10 1 1 19111 109 109 11110 110 108 108 120 101 120 102 S -- - F- - i.- Fig. 2A
