Description

Fixing device to fix the underwater tunnel in the water{FIXING DEVICE FOR UNDERWATER TUNNEL}

The present invention relates to a device for fixing an underwater tunnel, and more particularly, to a fixing device for fixing an underwater tunnel in the water that reinforces the fixing force of fixing a mooring line that is connected to the underwater tunnel to the underwater floor. will be.

As industries and industries develop rapidly internationally, the use of global resources such as petroleum is gradually increasing, and accordingly, stable production and supply of crude oil is emerging as a very important issue at a global level.

For this reason, the development of small marginal fields or deep-sea oil fields, which have been neglected due to lack of economics until now, has become economical, and with the development of subsea mining technology, drilling facilities suitable for the development of such oil fields have been established. A equipped rig has been developed.

The rig is a jack-up rig in which 3 to 6 footnotes installed on the barge are lowered to the sea floor and the pants are installed on the sea. A semi-submersible type supporting the deck, a linear shape like a hull, a buried artificial island type made of an artificial island by embedding soil, a gravity type and a disk type that endure waves or seismic forces by weight by submerging submarines in the sea floor. There is a disk floating body type that forms the floating structure of the image.

Among these rigs, jack-up rigs are often installed in rocky areas and soft ground. In the jack-up rig, a plurality of support pillar assemblies are installed toward a lower side from the jack-up rig, and a support member is installed at a lower end of the support pillar assembly.

However, the conventional jack-up rig has a problem that the equipment on the piping line is damaged due to the water hammer action that occurs due to the sudden change in water pressure that occurs when the motion state of the water in the pipeline is suddenly changed during the initial operation of the raw water pump on the performance line. there was.

In addition, in general, when building a ship in the shipbuilding industry, the entire ship is divided into several large blocks to be manufactured and then connected to complete the ship. In the shipbuilding industry, this process is called'mounting', but in this mounting process, a large crane must be used.

Therefore, in order to lift or move the manufactured block with a crane, a part to securely connect the crane to the block is required. In order to make such a connection part, each block is equipped with as many padeyes as necessary at an appropriate location, and these padeyes are separately manufactured and welded to the required area, and then a hook or hook of a crane to the padeye. Blocks are transported by shackle. Such a pad eye is one of several workpieces that work as overhead among the hull blocks and is lifted and installed in a tack welding position.

In other words, an underwater tunnel is a floating structure in which a foundation is made with a suction anchor, etc., and a connection is made between them using a tension leg method. In the method using a cable, a connection with the foundation must be presented. However, since the underwater tunnel is quite large, there is a problem that construction and manufacturing are not easy because the scale is quite large when designing the pad-eye, which is a connection part.

Welding is a method of bonding a metal material of the same or different types by applying heat and pressure to form a direct bond between solids. There are two methods: fusion welding and pressure welding. Specifically, the fusion welding method includes arc welding, gas welding, and thermite welding as a method of rearranging and bonding the atomic bonds of two different materials by heating and melting a metallic material at the junction. The pressure welding method is a method of bonding by applying strong external physical pressure to the joint, and a method of applying pressure and heating at the same time, such as gas pressure welding or single welding, is referred to as heating pressure welding or high temperature pressure welding. In general, materials with high ductility, such as aluminum and copper, are used for materials that use pressure welding, and because welding is possible only by pressing at room temperature, it is called cold compression welding.

Since the welding surface tends to be easily brittle, including impurities, a deoxidizing agent that removes oxygen or a flux that promotes dissolution so that the metal is well mixed is used, or an inert or reducing gas is used. In some cases, oxidation is prevented by using. The good and bad of the welding result is called weldability, and all of the target material, welding rod, and working conditions are affected during welding.

Nowadays, new welding technologies such as the electroslag method, which is a welding method using resistance heating of slag, which is used for welding of very thick plates, and the electron-beam method, which can weld materials with a high melting point, are being developed. have.
