Systems and methods for recovering power fluid used to power a device under water and for pumping the recovered power fluid to a fluid container above a surface of the water, the method in certain aspects including: flowing fluid from a subsurface apparatus to a subsurface recovery system, the fluid initially provided to the subsurface apparatus to power the subsurface apparatus; and the subsurface recovery system including a pump system for selectively pumping recovered power fluid to a fluid container above a surface of the water, the pump system having at least one pump and, in some aspects, a first pump, a second pump, and a valve system; the valve system controlling the first pump and the second pump to allow only one pump of the first pump and the second pump to pump recovered power fluid to the fluid container above the surface of the water; and pumping recovered power fluid to the fluid container with only one pump at a time. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 C.F.R. 1.72(b).
