Panzer VIII Maus
Panzerkampfwagen VIII Maus ("Mouse") was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armoured fighting vehicle ever built.

Marine LNG Engine
Samsung’s Supreme was a Mark-III type LNG container ship that was the largest of its kind. The Supreme had the newest technology seen in LNG ships. She features tanks completely surrounded by double bottom hull, and a cofferdam between tanks. Each tank stores its cargo at -163 degrees Celsius. This is a standard storage temperature for LNG This is accomplished by 250 mm of insulation, and a 1.2 mm thick stainless steel membrane. Each cargo tank has submerged centrifugal pumps to unload cargo rapidly. This is the standard unloading method for LNG tanks. The maximum drought for LNG ships is typically 12 meters. This is due to harbor facilities sizes and restrictions. The most common size of LNG vessels ranges between 120,000 and 180,000 cubic meters because of ship dimensions.
