Problems solved by technology

However, no matter which mooring system is used, there are common defects: 1. As the water depth increases, the horizontal stiffness of the mooring system decreases, which intensifies the movement of the floating structure in the plane (surge, sway, etc.) and yaw); 2. The vertical stiffness that can be provided is limited, whic

Abstract

The invention discloses a self-adaption type deepwater mooring system which comprises a hanging buoy, a weight block, a mooring buoy, an anchor, a pile foundation, an upper tensioning cable, a connecting cable, a lower tensioning cable and a tension tendon, wherein the upper tensioning cable is used for connecting the hanging buoy with the weight block; the connecting cable is used for connecting the weight block with the mooring buoy; the lower tensioning cable is used for connecting the mooring buoy with the anchor; and the tension tendon is used for connecting the mooring buoy with the pile foundation. The self-adaption type deepwater mooring system has the advantages of high horizontal mooring rigidity, high vertical mooring rigidity and uniform tension distribution of a cable.

Description

technical field [0001] The invention relates to the field of mooring, in particular to a novel deep-water mooring system suitable for deep-water marine engineering structures. Background technique [0002] With the depletion of onshore oil and gas resources, the development trend of offshore oil and gas has shifted from offshore shallow water to far sea deep water. The deep-sea floating structure is the main equipment for the development of deep-water oil and gas resources. No matter what kind of floating structure is used, it needs a mooring system to moor it in a fixed sea area for a long time. The mooring system is an important guarantee for the normal operation and safety of floating structures, so it plays a pivotal role in deep sea development. [0003] At present, there are two types of deep water mooring systems: catenary mooring system and tension mooring system. However, no matter which mooring system is used, there are common defects: 1. As the water depth incre...
