Abstract

The invention relates to a pipe-ship connection method suitable for deep-sea mining, and belongs to the field of deep-sea mining. A ball joint, a telescopic device and an adjustable short section forma pipe-ship connection device for compensating pipeline heave displacement and angular displacement produced by waves. A clamping plate is used as an underwater conveying system hanging and bearing body in the hard pipe lowering and elevating-conveying process. Through heave compensation systems, the impact on a water surface supporting platform due to a heavy load system heave motion impact loadunder the severe sea condition is reduced, an ore pulp is conveyed stably relatively, the fatigue damage and the dynamic compression risk of an underwater conveying system are retarded, and the overall operation safety is improved. A hydraulic control system provides a power source for the pipe-ship connection device. The pipe-ship connection method suitable for deep-sea mining provided by the invention solves the problem that heave compensation system hard pipes drift to touch a moon pool under the circumstance that the horizontal direction is unlimited; avoids the risks of butt-joint and configuration of an ore pulp conveying hose under a base platform and a test link; and has double safety guarantees, can realize quick switch and recovery under the emergency state, and provides convenience for offshore layout and recovery work.

Description

technical field

[0001] The invention relates to the field of deep-sea mining, in particular to a pipe-ship connection method suitable for deep-sea mining. Background technique

[0002] As a complex system engineering, deep-sea mining engineering integrates a variety of technologies and equipment from multiple disciplines and fields. The deck of the mining ship is equipped with numerous water surface support system equipment, which is a support platform for the deployment of mining equipment such as recovery mining vehicles, hoses, conveying hard pipes, relay stations and lift pumps. The hard pipe system is suspended under the mining vessel and deployed hundreds of meters to thousands of meters underwater. It is a key component connecting underwater mining vehicles, hoses, relay stations and lift pumps. Its main function is to provide slurry The conveying channel carries the deployment and recovery of underwater equipment, as well as the fixing of umbilical cables of underwa...
