<p>The present invention relates to a device for testing a load of a navigation-off trolley of a drilling ship and, more especially, to a device for testing a load of a navigation-off trolley of a drilling ship performing a load test after loading multiple weights having predetermined volume and weight on the top surface of the trolley installed on the upper part of a moon pool formed on the center of a hull to move along the rail. The device for testing the load of the navigation-off trolley of the drilling ship is characterized by installing an auxiliary zig having a rectangular plate on the top surface of the trolley having an U-shaped through-hole on the front side and installing a water pocket having predetermined volume on a locking hook, which is installed to be projected from the center of the bottom of the auxiliary zig, to be attached or detached. Therefore, the load test of the trolley can be accurately performed regardless of a limited area of the trolley or the limited weight or volume of the weights and an upper space of the trolley so that the accuracy and reliability of the load test of the navigation-off trolley of the drilling ship can be remarkably improved.</p> |
