Heavy lift vessels are quite amazing vessels, built to load, carry and discharge large, unusual shaped cargoes (or even smaller vessels) that will simply not fit inside the holds of conventional vessels.
Unusual cargoes can include power plants, submarines, desalination units,oil platform, generators and yachts.
