[0002] A heavy-lift vessel is a specialized vessel used to transport heavy cargo, equipped with large cranes and other lifting equipment for loading and unloading. A heavy-lift vessel stabilization buoy is a device temporarily installed on the side of a heavy-lift vessel. It primarily increases the vessel's buoyancy and stability, providing additional support when loading or unloading heavy cargo and preventing the risk of excessive tilt or capsizing due to excessive lifting.
