Mooring device and fastening method for a movable floating dock

Abstract

A movable floating wharf anchoring device and securing method, including a floating wharf, a lifting column is installed at the head of the floating wharf, the center line of the lifting column is perpendicular to the upper surface of the floating wharf, and the floating wharf The lifting column controls the lifting work through the hydraulic system, and the lifting column is also connected to the floating dock through the support device, and the rotation of the floating dock is controlled through the support device. The upper surface of the floating dock is fixed with a control tower, and the floating dock There are windlass fixed at intervals at the tail of the wharf, the windlass is connected to one end of the anchor chain, and the other end of the anchor chain is installed with a large anchor. It eliminates the impact on the navigation and operation of surrounding ships, and can meet the special berthing requirements of various ships of comparable size. When encountering a large typhoon and high wind and waves, the floating dock can switch the securing method and resist the wind and waves on the spot.

Description

technical field [0001] The invention relates to the technical field of marine engineering and shallow-water floating dock mooring, in particular to a movable floating dock mooring device and a fastening method. Background technique [0002] With the continuous development of my country's marine economy, it is necessary to use a large number of mobile floating docks that do not damage the marine ecological environment for flexible cargo berthing and material loading and unloading. During humanitarian rescue and emergency disaster relief, there is an urgent need to temporarily deploy flexible offshore and coastal floating docks for the berthing of rescue ships and the emergency transfer of disaster relief materials. [0003] With global climate warming in recent years, typhoons are frequent and their levels are gradually increasing, and the sea storm environment is getting worse and worse. To a large extent, it is a test of the mooring and fixing capabilities of shallow water m...

Problems solved by technology

At present, the anchoring methods of shallow water floating wharf mainly include pile-inserting fixed, catenary or tensioned multi-point mooring methods. Among them, the pile-inserting fixed type cannot be relocated and reused, and the seabed geological requirements are high, and the adaptability is not enough. strong, and at the same time need to be coordinated by a large number of engineering ships, so the cost of pile insertion is also high

The catenary and tension multi-point mooring methods usually arrange multiple mooring points at the corners of the floating wharf or along the perimeter, and the mooring chains on each mooring point extend radially around, and then pass through The anchoring device anchors the mooring chain on the seabed. Although this type of chain multi-point mooring has strong positioning ability and the floating body is not prone to large positioning deviations, it also has defects: first, when the cargo ship docks on the floating wharf along the horizontal direction When it is sideways, it is easy to collide with the mooring chain of the floating dock and cause damage to the mooring system or the ship, which is very unfavorable to the lateral berthing and operation of the ship and the navigation and operation of surrounding ships; second, each mooring chain directly Fixed on the seabed by anchoring devices, more anchor points are required, and the construction and installation of the entire mooring system requires more cost and time, and the economy and timeliness are poor

At the same time, the marine transportation and deployment of many ocean engineering and offshore floating dock equipment are very difficult and expensive, and often need to be completed by a large number of engineering auxiliary ships. Therefore, offshore floating docks need to find an economical and efficient anchoring method. Devices and securing methods are necessary
