SIDER Testing of Royal Navy Vessel P292 HMS Trumpeter

摘要

This report documents work performed by the Naval Surface Warfare Center, Carderock Division in support of The Technical Cooperation Program (TTCP), composite panel TP-7, Operating Assignment 026, on the durability assessment of composites in the service environment. This is part of ETA-10, composite performance and long-term durability under dynamic, thermal and shock loading. This report presents the results of a single Structural Irregularity and Damage Evaluation routine (SIDER) inspection of the forecastle of EMS trumpeter, pennant number P292. The forecastle consists of a balsa or plywood core with glass composite facesheets and a top layer of nonskid. The SIDER inspection identified several regions that had changes in structural stiffness. Several of these indications corresponded to structural features in the hull such as deck prisms, vents, and areas where bulkheads terminated. In addition, there was an indication identified where the nonskid material was debonded from the deck. The SIDER inspection failed to identify many nonstructural irregularities since the ship was nearing completion of its refurbishment.
