Speaking of more specific samples, there is Blue Marlin, which is the world’s largest semisubmersible vessel. Such vessels have a narrow specialization. Semi-submersible transport vessels are designed for moving large-sized, extremely heavy loads, such as sections of offshore and oil platforms, submarines, cranes, ships, moorages, etc.
Blue Marlin and its twin Black Marlin come in a class of heavy ship-lifts. They belong to a company from Oslo – Offshore Heavy Transport. They were built in April 2000 and November 1999 respectively.
