Abstract
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).
