Problems solved by technology

[0004] However, the action of throwing stones will affect the stability of the base
The traditional stone throwing system has the effect of being unable to locate, and can only throw the stone at an approximate position
In addition, riprap boats are also vulnerable to currents, waves, and wind, making riprap operations imprecise
It causes the catapult to waste other materials such as stones, which is more time-consuming and costly in addition to increasing the number of trips

Abstract

The invention relates to a dynamic rock dumping and positioning system. The dynamic rock positioning module 300 is configured on a vessel B to dump rocks or other material via a fallpipe 100. The system has a slider 200 connected to the fallpipe, a swing module 300 connected to the fallpipe and a control module 400 connected to the slider. The control module adjusts a swinging motion of the fallpipe and the slider controls a sliding motion of the fallpipe. The pipe is automatically stabilised via an active compensation which is actuated by the dynamic positioning rock dumping module. Later embodiments relate to an operating method for the dynamic positioning rock dumping system and an operating method for the dynamic positioning rock dumping system.

Description

technical field [0001] The invention belongs to the technical field of ship riprap drop mechanism, and mainly relates to an oblique riprap drop mechanism with position compensation function and its operation method. Background technique [0002] For facilities that need to operate offshore, it is usually necessary to do additional processing on the seabed, such as piling or fixing, positioning brackets, etc., before subsequent underwater and surface engineering can be implemented. In recent years, these operations have mainly focused on bridge building, offshore operating platforms and erection of offshore wind turbines. [0003] Among them, in the part of fixing the base of the seabed, it is quite a common idea and technology to use a riprap boat to riprap stones and stack stones on the seabed to support part of the structure. Traditional rock throwing methods are mostly divided into two techniques: hose and hard pipe. In deeper sea areas, hoses are usually used, while in...
