Submersible pumps are mounted on two vertical guide rails and seal onto a permanently fixed "duckfoot", which forms both a mount and also a vertical bend for the discharge pipe. For maintenance or replacement, submersible pumps are raised by a chain off of the duckfoot and up the two guide rails to the maintenance (normally ground) level.

To pump water from the tanks, there were two 24-inch (61 cm) discharge pumps on each section, each pump rated 15,000 US gallons (57,000 L) per minute. For electricity, there were two 350-kw diesel AC generators on each section, producing 440 volts 3-phase 60-cycle power.
