The invention discloses a ship and ocean structure corrosion protection status assessment and control method. The method includes the following steps that: S1, a ship and ocean structure corrosion protection status assessment database is established; S2, ship and ocean structure spatial coordinates are established through three-dimensional software; S3, an assessment area is demarcated according to the contour of a ship and ocean structure; S4, detection electrodes set as detection points according to the assessment area are adopted to collect the resistance of the collection points of the body material of the ship and the ocean structure; S5, resistance values collected by the detection electrodes in the S4 are compared with reference values in the database, so that the corrosion protection status of the body material can be analyzed; S6, the thickness of the anti-corrosion layer of the surface of the ship and ocean structure is sampled according to the assessment area; and S7, the thickness of the anti-corrosion layer collected in the S6 is compared with a corrosion layer reference value in the database, so that the surface corrosion protection status of the ships and ocean structure can be analyzed.
Description
technical field [0001] The invention relates to the technical field of corrosion protection state evaluation of ships and marine structures, in particular to a method for evaluating and controlling the corrosion protection state of ships and marine structures. Background technique [0002] The surface of ships and marine structures is usually equipped with an anti-corrosion layer, but there are still a large number of substances that corrode ships and marine structures under the ocean and in the air. Ships and marine structures are more corrosive. The dangers brought by corrosion can be imagined, therefore, it becomes very important to evaluate the corrosion protection status of ships and marine structures. [0003] Prior art CN104794349B provides a corrosion protection state assessment and control method for ships and marine structures, which has a database establishment step: establishing a boundary element model of underwater structures of ships and marine structures, an...
