One of the things I toyed with in Arctic Rising is the idea of a floating factory. The benefit being that you could a) get offshore and away from labor rights and minimum wage and b) but still keep your factory close to where sales ended being needed. Additionally, you could reposition the factory as needed.
Apparently the economics make sense with processing natural resources, Shell is about to build the world’s largest ship:
Shell will forge the hull of a floating [liquefied natural gas] plant in South Korea by year-end that will be the world’s largest vessel, weighing six times the biggest aircraft carrier, a Nimitz-class warship. Some 5,000 workers will build the factory to produce LNG off Australia’s northwest coast in a $13 billion project that also will shield Shell from escalating costs it would have to pay at the country’s onshore plants.
