Semi-submersible vessel cargo description: Semi-submersible vessels adjust the vessel's buoyancy through ballast water, allowing the deck to submerge for float-on/float-off operations. They have strong load-bearing capacity and open cargo space, suitable for various oversized, overweight, and out-of-gauge cargoes. They can transport large ships, offshore platforms, wind power equipment, heavy engineering machinery, large tanks, bridge components, and various heavy-lift and breakbulk special cargoes, without being limited by conventional loading and unloading, making them ideal for long-distance ocean heavy-lift shipping.
