Embodiment 1

[0035] Such as Figure 1 to Figure 5 As shown, the present invention discloses an installation and adjustment method for a deep-water net cage mooring system, which is suitable for a deep-water net cage mooring system provided with N anchor legs 1, and each of the anchor legs 1 surrounds the floating pipe of the deep-water net cage The centers 2a of the frame 2 are evenly spaced, N≥4;

[0036] The installation adjustment methods described include:

[0037] Step S1, measuring the mooring stiffness curve of each anchor leg 1, the measurement method is as follows:

[0038] Step S1.1, record the anchor leg 1 for the mooring stiffness curve measurement this time as the main anchor leg 1-1, and use the towing ship 4 to tow the floating pipe frame 2 of the deep-water net cage to move along the testing direction V, Until the pulling force F of the towing ship 4 to the floating pipe frame 2 of the deep-water net cage reaches the upper limit value Fmax of the pulling force;

[0039] ...

Embodiment approach

[0051] In the step S1.1, the mooring point 1-1a of the main measuring anchor leg 1-1 on the floating pipe frame 2 of the deep water net cage is connected with the towing ship 4 with a traction rope 3, and The towing boat 4 drags the floating pipe frame 2 of the deep-water cage to move along the testing direction V through the towing rope 3 ; the pulling force F is the tension of the towing rope 3 .

[0052] Thereby, it is avoided that the measurement process of the mooring stiffness curve causes damage to the floating pipe frame 2 of the deep-water net cage.

Embodiment 3

[0054] On the basis of the above-mentioned embodiment 1 or embodiment 2, this embodiment 3 also adopts the following preferred implementation modes:

[0055] In the step S1, according to the order of the N anchor legs 1 along the circumferential direction of the floating pipe frame 2 of the deep-water net cage, the mooring stiffness curve is measured for the anchor legs 1 one by one.

Abstract

The invention discloses an installation and adjustment method of a deepwater net cage anchoring system. The installation and adjustment method comprises the steps that S1, measuring a mooring stiffness curve of each anchor leg; comparing effective anchor leg tension Ki corresponding to the mooring stiffness curves Li-Ki of the N anchor legs when the horizontal displacement Li is the maximum horizontal displacement Lmax, wherein the maximum effective anchor leg tension Ki is recorded as the maximum effective anchor leg tension Kmax, and the minimum effective anchor leg tension Ki is recorded asthe minimum effective anchor leg tension Kmin; and S3, if Kmax-Kmin is smaller than or equal to K, judging that installation of a deepwater net cage anchoring system is qualified, or otherwise, decreasing the mooring radius of the anchor leg corresponding to the maximum effective anchor leg tension Kmax, and increasing the mooring radius of the anchor leg corresponding to the minimum effective anchor leg tension Kmin. The method can detect whether the installation construction of the deepwater net cage anchoring system is qualified or not, can accurately and efficiently adjust the anchor legswhich are unqualified in installation, has the advantages of being high in operability, high in precision and low in implementation cost, and facilitates the improvement of the installation construction quality of the deepwater net cage anchoring system.

Description

technical field [0001] The invention relates to an installation and adjustment method of a deep-water net cage mooring system. Background technique [0002] The cage industry is developing rapidly. There are a large number of cages at present, and the mooring form is mainly multi-point mooring. However, due to the current situation of industrial development, the actual installation is relatively random without professional mooring construction equipment and professional technical teams. , There are often major problems with the installation quality, and these quality problems are not easy to detect because the mooring system is located underwater. However, how to find these problems, complete repairs efficiently, and pass the inspection is a blank in the current industry. [0003] The anchoring construction process of the cage is roughly divided into several steps. The first step is to complete the production of the anchor legs required by the cage, including anchors, anchor...
