Problems solved by technology

This cannot be satisfied most of the time in the Pacific Ocean and China's coastal waters such as winter
In the actual past operation process, in order to slow down the shaking during release and recovery, one section of the rope is usually used to connect the underwater equipment, and the other section is assisted by manually adjusting the tightness of the rope after the bollard is installed. The effect is not good. It also has a certain impact on the safety of operators.

Embodiment

[0013] The present invention provides a method for releasing and recovering high wind and wave resistant underwater equipment, the steps of which are as follows:

[0014] Step 1. Install two winches with a constant tension function and a safety load of 10 tons on the deck of the underwater equipment release and recovery operation ship. The winches need to be equipped with a matching steel wire rope with a safety load of 10 tons. Install two ground orders with a safe load of 10 tons on the portal columns on both sides of the hoisting equipment (type A gantry crane) of the underwater equipment. Weld two fixed ground orders on both sides of the underwater equipment. According to the engineering requirements and the actual situation of the operation, guide pulleys are installed on the deck to guide the direction of force when the underwater equipment is released and recovered.

[0015] Step 2. The front end of the hoist wire is connected to a super-reinforced fiber rope with a di...

Abstract

The invention provides a method for releasing and recovering underwater equipment with high wind wave resistance. The method is characterized by comprising the following steps of: fixedly mounting two winches with constant tension function on a deck of an operation ship; respectively mounting ground piles on hoisting equipment of the underwater equipment and on the underwater equipment; then connecting front ends of the winches with ultrastrong chemical fiber ropes; keeping constant stress of the winches until the underwater equipment enters into water during releasing the underwater equipment; dismantling the ultrastrong chemical fiber ropes connected with deck ground piles; releasing the underwater equipment and continuously carrying out conventional release operation; and keeping the constant stress of the winches until the underwater equipment is stably fixed on the deck during recovering the underwater equipment, dismantling the ultrastrong chemical fiber ropes and finishing the recovery operation. The invention has the advantages of increasing time windows for releasing and recovering the underwater equipment, improving the wind wave resistance of the underwater equipment for releasing and recovering, overcoming the risk on the equipment and constructors caused by the shake of ships in the traditional process and improving the safety and the reliability of the construction while improving the self construction capability.

Description

technical field [0001] The invention relates to a method for releasing and recovering underwater equipment with high wind and wave resistance, and belongs to the technical field of submarine cable construction methods. Background technique [0002] The release and recovery of traditional underwater equipment mainly use lifting equipment, such as A-type gantry cranes and the longitudinal anti-sway devices that come with gantry cranes. Due to the huge size and dead weight of underwater equipment (for example, the 3-meter buried plow equipped with Fuhai ship has a length of 10.5 meters, a width of 5.6 meters, a height of 5.7 meters, and a weight of 28 tons), so the release and recovery of underwater equipment require sea conditions. The maximum sea state level is 5, and the wind force is 6. This cannot be satisfied most of the time in the Pacific Ocean and China's coastal waters such as winter. In the actual past operation process, in order to slow down the shaking during rel...
