Problems solved by technology

At present, in deep sea salvage, there are mainly two methods for sinking large objects in the water. One is to salvage by using claws to grab the sunken objects. Further damage to the submerged object occurs during the removal of the submerged object from the water
The other is to use the lifting equipment on the salvage ship to lift the sunken object by placing the steel cable under the sunken object. In this way, two or more salvage ships are generally required to work together, and the cooperative work requires high requirements. In the process of pulling the steel cable under the sunken object, it is necessary to drill the bottom of the sea and then thread the sling, which is cumbersome and inefficient

Embodiment 1

[0041] see figure 1 , the present embodiment is a kind of deep sea salvage operation method, comprises the following steps:

[0042] Step S1: Determine the salvage position, and drive the salvage ship directly above the sunken object;

[0043] Step S2: lowering the salvage device, and vertically sinking the salvage device from the salvage ship to the sediment layer on the seabed through the cable lifting device on the salvage ship, and the sunken objects are located in the area surrounded by the salvage device;

[0044] Step S3: Set up the sling under the sunken object, and the spiral rail on the salvage device moves linearly on the salvage device in a spiral progressive manner. When the spiral rail drills into the sediment layer, the sling and the spiral rail drill through the bottom of the sunken object together , making the sling under the sunken object;

[0045] Step S4: Salvage the sunken objects, and lift the sunken objects by the steel strand jack system and the sling...

Embodiment 2

[0054] see figure 2 , image 3 , the present embodiment provides a catamaran deep-sea salvage operation ship adopting a deep-sea salvage operation method of the above-mentioned embodiment. 1 sinks vertically to the bottom of the sea.

[0055] see figure 2 , the hull of the hull 1 is provided with a sinking chamber 11, the sinking chamber 11 is a structure with openings at both ends in the vertical direction, the salvage device 2 sinks vertically into the sea through the sinking chamber 11, and the bottom of the sinking chamber 11 There is a water barrier 12 at the end.

[0056] see Figure 5-Figure 12 , the fishing device 2 comprises a left drive base 3, a right drive base 4 and a spiral rail 5 between the left drive base 3 and the right drive base 4, the left drive base 3 and the right drive base 4 are arranged parallel to each other, the left drive base 3 and The right drive base 4 is provided with a drive member 6 and a linear drive device 7 for driving the drive mem...

Abstract

The invention discloses a deep sea salvage operation method. The method comprises the following steps of determining a salvage position, lowering a salvage device, arranging a sling under a submerged object, and salvaging the submerged object. According to the invention, the salvage of large submerged objects is realized through a single ship, the resource demand of salvage work is reduced, the resource waste is avoided, and the condition of salvage failure caused by improper cooperation in the cooperative salvage process is avoided.

Description

technical field [0001] The invention relates to the field of deep sea salvage, in particular to a deep sea salvage operation method. Background technique [0002] The sediment layer in the sea refers to the special stratum formed by the sediment brought by the movement of seawater and the remains of marine organisms. The thickness of the sediment layer covering the ocean is between 0 and 4000 meters, and it may be thicker in the deep water basin. , the average thickness of ocean deposits throughout the world is 300 meters. On the seafloor, submerged objects are usually located on sedimentary layers. [0003] Underwater salvage is the project of salvaging sunken objects in water, including salvage of ships, aircraft, cargo, etc. Salvage operations in waterways and port waters can achieve the purpose of clearing navigational obstacles. At present, there are two main methods for deep-sea salvage for large objects sunk in water. One is to salvage by using claws to grab the su...
