Category 1 tankers have been phased out in 2005. These so-called preMARPOL tankers were single hull only with some segregated ballast tanks. Around one third of the cargo tanks also acted as ballast tanks. During ballast discharge oil was released into the environment.
Cross section of a vessel with a single ballast tank at the bottom. A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural ...
Modern double hull tankers, with their fully "segregated ballast tanks" propose another problem. Empty tanks act as insulation from the cold sea and allow the warm cargo areas to retain their heat longer. Corrosion rates increase with differences in temperature.
The ship's ballast water capacity of 46,922.4 cubic metres (1,657,050 cu ft) is divided into sixteen segregated ballast tanks, six pairs in the double hull around the cargo tanks, two fore peak tanks and two aft peak tanks. [21] She has two electrically driven ballast pumps rated at 2,500 m 3 /h × 35 m and 3,000 m 3 /h × 70 m. [8]

The upper and lower corners of the hold are used as ballast tanks, as is the double bottom area. The corner tanks are reinforced and serve another purpose besides controlling the ship's trim. Designers choose the angle of the corner tanks to be less than that of the angle of repose of the anticipated cargoes. [14]
