Description

An anchor chain with a tension sensor

technical field

The utility model relates to a shock absorbing restraint device for marine engineering, in particular to an anchor chain with a tension sensor.

Background technique

When human beings are on the coast, they need to build ports for ship berthing, personnel transportation, and loading and unloading of materials. Sometimes in order to adapt to changes in tide levels, it is necessary to build barges and pontoon systems on the water surface for ship berthing and material transportation channels. platform. Moreover, due to the increasing frequency of human activities in the deep sea, it is often necessary to build large floating structures such as artificial islands. The traditional positioning of this kind of floating structure is mostly made of steel pipe piles. However, due to environmental factors such as water depth, waves, and tide levels, this positioning method is very expensive and has poor wind and wave resistance. At this time, the tension mooring system of the anchor chain has great advantages, such as excellent anti-wind and wave performance, convenient construction, short construction period, and can greatly save engineering investment.

Due to the limitation of resources in shallow sea areas, the current offshore oil and gas exploitation and ocean energy development have the opportunity to develop into the deep sea. As the working water depth increases, the cost of fixed structures will increase significantly, which also leads to the inability of traditional fixed offshore structures to meet engineering requirements. need. Common floating body structures include semi-submersible platforms, FPSO, TLP, and SPAR. Functionally, they can be divided into oil and gas extraction facilities such as drilling platforms, production platforms, storage and transportation ships, or buoys, floating offshore wind power, and ocean energy power generation facilities. The common feature of the above-mentioned floating offshore structures is good hydrodynamic performance. Unlike the completely rigid fixed structure, the floating body has a certain degree of flexibility, and the structural stress is relatively small and difficult to damage under the action of waves and currents. For floating structures, the mooring system is the key to the safety of the structure and the normal realization of functions. There are two types of mooring systems: catenary and tension. Among them, the tension system makes the out-of-plane motion of the structure well controlled, and the hydrodynamic performance is good. Steel wire ropes or polymer material ropes are commonly used in tensioned mooring systems. The development trend is to reduce the weight and increase the strength and bearing capacity.
