This article introduces the testing methods for various types of ship coatings、 and focuses on exploring the testing methods for ship rust prevention paint、 anti fouling paint、 ship ballast tank paint、 and crude oil tanker cargo tank paint. Looking forward to the development direction of ship coating inspection methods. Ships traveling at sea are affected by various corrosive environments. Above the waterline、 the deck and superstructure are affected by the high salinity、 humidity、 and radiation of the marine atmosphere; Below the waterline、 the ship's hull is not only corroded by seawater、 but also attached to various marine organisms (such as barnacles、 oysters、 seaweed、 etc.)、 which not only greatly increases navigation resistance and reduces navigation speed、 but also causes more fuel consumption and even maritime accidents; Tanks carrying various corrosive media、 such as sea water ballast tanks、 crude oil cargo tanks、 chemical tanks、 etc.、 have always been a concern for shipbuilding and shipping departments due to their long-term exposure to seawater、 crude oil、 highly corrosive chemicals、 and other environments. For hydraulic natural gas vessels、 the fire resistance performance of fire-resistant materials is the first consideration、 but it is also crucial to prevent extreme low temperature (as low as -198 ℃) impacts caused by hydraulic natural gas leakage. At present、 coating is one of the main measures for anti-corrosion、 anti fouling、 and special protection of ships. With the continuous development of science and technology、 the performance of ship coatings has also been greatly improved. For example、 high weather resistant topcoats and high solid universal epoxy anti rust coatings have been widely used in ship shells、 hulls、 and other parts. In addition、 with the continuous improvement of environmental regulations、 ship coatings are also paying more and more attention to environmental protection. In 2015、 the State Administration of Taxation issued regulations on the collection of paint consumption tax、 and the National Coatings Standardization Technical Committee is also preparing national standards for the "Limit of Harmful Substances in Ship Coatings". Reducing the content of volatile organic compounds (VOCs) and reducing the use of toxic and harmful antifouling agents has become an important trend in the development of ship coatings
