Submarine Mystery Question of the Week - 9/7/2010

Background
The concept of air conditioning is known to have been applied in Ancient Rome, where aqueduct water was circulated through the walls of certain houses to cool them. Similar techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the hot season. Modern air conditioning emerged from advances in chemistry during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902 by Willis Haviland Carrier

For centuries, people on sea voyages washed their clothes by placing the dirty laundry in a strong cloth bag, and tossing it overboard, letting the ship drag the bag for hours. The principle was sound: forcing water through clothes to remove dirt.

Before something new is adapted fleetwide (on newer construction, at least) trial(s) on selected platform(s) was/were necessary to prove it performs at least as well as expected.

For this week' questions particularly, documentation is required to prove earlier dates and platforms than M.E. has tentatively found.
