This paper presented an identification platform of acoustic emission signals of offshore structures supported by the open country-wide interconnected database and based on local wave recognition arithmetic. The platform had the ability manage a lot of acoustic emission signal experimental data of offshore structures and study the nature of the acoustic emission signals. The general structure and some new recognition arithmetic principle were introduced. And then on this basis, by using the program tools such as Power Builder and Matlab, in combination with database technique, the data and algorithm of acoustic emission signals of offshore structures were combined by designing several interfaces. The results showed that the identification platform had powerful functions with easy operation, and had more practical values.
