Experimental stress analysis of a full-diving barge hull

A full-driving barge refitted by a 2000t deck barge would be used for salvaging at the sea of which the planned diving depth will reach to 14 m. The hull structure would suffer form different but complicated loads because of the refitting and actual diving process, and the structure should be analyzed and approved by calculations and experiments. The test was carried out at the site of Santou bay. A multi-channel static-dynamic strain test system was adopted to survey the main components of the hull structure under load cases. The hydraulic pressure was mainly considered and divided into different classes in diving process. The readings of strain gauges in different components were processed by a computer linking to the test system. It was shown that the results were coinciding with the calculated results. And it is concluded that the refitted full-diving barge hull is safe at the designed depth.
