RMS Amazon, diving off Donegal (low res), boilers, galley area, engine

The opening sequence is the galley area of the Royal Mail Steamer RMS Amazon - a 10,000 ton luxury liner / merchant cargo ship, built in 1906 by Harland & Wolff and torpedoed by U-Boat U-110 on 15/03/1918. The dive moves between the six boilers and continues towards, and aft of, the quadruple expansion engine. 40 minutes bottom time at a depth of 115m gave over 4 hours of decompression obligations, at a sea water temperature of 10C (bottom) and 13C above 12 metres (where half of the dive time is spent).
