Semi-submersible ships are the only vessels in the world which provide the capability to load, transport and offload extremely heavy cargo, such as oil drilling rigs, gas refineries or even warships
Their large, free and open deck makes them the largest heavy transports in the world. They are capable of loading lifts from approximately 50 to as much as 45,000 tons.
How they work?
A semi-submersible heavy-lift ship, or also known as a "flo/flo" (for float-on/float-off), has a long and low well deck between a forward pilot house and an after machinery space.
Its ballast tanks can be flooded to lower the well deck below the water's surface, allowing oil platforms, other vessels, or other floating cargo to be moved into position for loading.
The tanks are then pumped out, and the well deck rises to shoulder the load. After the vessel is full afloat, the cargo is secured for transport.
