Description

Detachable pontoon and configuration system suitable for marine floating hose Technical Field The invention relates to the technical field of ocean engineering, in particular to a detachable pontoon and a configuration system suitable for an offshore floating hose. Background Floating hoses are often used across sea wave zones when fluid or slurry transfer is performed between sea vessels. To ensure that the hose is sufficiently buoyant and stable in attitude, it is often necessary to provide a pontoon or buoyancy module outside the hose. However, the pontoons of the prior art suffer from a number of problems: the installation efficiency is low, and the existing pontoon mostly adopts an integral cladding type, a bolt clamping type or a structural form that a hose needs to be penetrated from the pontoon. These structures are complex to operate when installed offshore, resulting in inefficient installation. For example, the integral cladding pontoon needs to be sleeved on the hose integrally, the offshore operation space is limited, the operation difficulty is high, and the time is long. The bolts clamp type buoy uses a large number of fasteners, so that the workload of installation is increased, and the degree of dependence on manual operation and tools is high. Under severe offshore environmental conditions, manual operation is inconvenient, and the use of tools is easily limited, further affecting installation efficiency. The disassembly is inconvenient, and when the hose needs to be reeled, overhauled or the end joint is replaced, the traditional pontoon is difficult to disassemble quickly. This allows for a considerably longer deck working time, while increasing the risk of working. For example, in offshore continuous operation scenarios such as deep sea mining wet transportation, the repair and maintenance of hoses requires frequent disassembly of the pontoon, and the inconvenient disassembly characteristics of conventional pontoons severely affect the efficiency and reliability of the operation. Therefore, there is a need to develop a structural solution that can realize quick assembly, reliable self-locking and quick release and disassembly of the pontoon, and to match with a tooling suitable for deck operation, so as to improve the efficiency and reliability of offshore continuous operation scenes.
