Measuring method of embedded movement locus of towing anchor in soil body and device thereof

Abstract

The invention belongs to the technical field of ocean engineering and relates to a measuring method of an embedded movement locus of a towing anchor in soil body for an ocean platform anchoring system; the method comprises the following steps: (1) a drawing wire sensor is fixed; (2) a double-shaft tilt angle sensor is embedded in the towing anchor, the axes of the double-shaft tilt angle sensor and the axes of an anchor plate are aligned for ensuring anchor shank connection to be symmetrical by taking the axes of the anchor plate as symmetry line; (3) the drawing wire of the drawing wire sensor is connected to the tail part of the towing anchor by a pulley block; (4) the towing anchor is arranged on a sea bed surface for forming initial embedding angle; (5) horizontal external force is exerted on the towing anchor on the axes of the anchor plate, so as to lead the towing anchor to be embedded in the soil body and collect signals obtained by the drawing wire sensor and the double-shaft tilt angle sensor in a real-time manner; (6) the momentary horizontal and longitudinal coordinates of the towing anchor is computed iteratively for obtaining complete embedded movement locus of the anchor plate in the soil body. The invention provides a measuring device for realizing the method at the same time. The measuring method and the device have the advantages of simple equipment, easy implement and high precision.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and in particular relates to a measurement technology for embedding a motion track of a towed anchor in soil. Background technique [0002] In the development of deep-sea oil and gas resources, with the gradual increase of large and super-large offshore compliant structures, mooring systems suitable for deep water and ultra-deep water have attracted increasing attention. The research and development of new deep-water mooring systems and new deep-water mooring technologies has become an important research field in the development of international offshore oil and gas resources and the international ocean engineering technology community. [0003] In the mid-1980s, it was discovered that the deep sea contained rich oil and gas resources, which set off an upsurge of research on deep sea oil and gas resource development technology all over the world. With the advancement of oil and gas ex...
