Abstract (en)

A submersible pumping system is disclosed for pumping cryogenic liquid from a reservoir (1) in which an electrically powered motor/pump unit (34/32) is located in an operative position at the bottom of a fluid transmitting casing (14) in the reservoir (1). The motor/pump unit (34/32) is electrically connected to a power source and to ground by means of flexible electrical and ground conduits (62/64), and is raised and lowered through the casing by means of support (56) and lift cables (76). The flexible conduits (62/64) and support cable (56) are arranged within a flexible sheath (60) to thereby provide a multi-strand cable which is separated from the lift cable (76) by detachable brackets (80).
