Research Of Digital Accuracy Supervision

The market of shipbuilding is amplitude but full of furious competition. The shipbuilding of China exists technical disadvantage contrast to Japan and Korea, especially in the field of digital accuracy supervision. The digital accuracy supervision is inevitable trend of accuracy shipbuilding development. It plays the important role on shortening the shipbuilding period, reducing shipbuilding cost and improving shipbuilding quality etc.... The digital accuracy supervision is based on specific hull accuracy datum line. The three dimension data are measured and analyzed using total station and advanced management software. The accuracy compensation and anti-distortion are improved based on data analysis and statistic. At the same time the digital measurement and analysis is used for simulate erection. The excess of erected block (general block) is cut on the platform, and assembled at one time. And this method improves the production efficiency. The accuracy standards are authorized based on data analysis and statistic, pledging the implement of the digital accuracy supervision.The digital accuracy supervision is pushed to increase hull building accuracy, reducing the repair of building process.
