Hull Strapping of Ships.
Abstract
A survey was conducted to U.S. and worldwide shipowners, ship operators, shipyards, and major international classification societies by means of a questionnaire and follow-up correspondence. Detailed information was requested and obtained for fourteen ship classes which have had hull strappings installed to strengthen the ship hull girder due to lengthening. Data was collected on the location and extent, the geometry and dimensions and the method of attachment of strappings plates to the hull as well as end tapering details and faying surface tightness provisions. In addition, in-service performance data were obtained for past strappings from the U.S. Coast Guard inspection database. The results were sorted, reviewed and analyzed with regard to the successfulness of the strapping designs and a practical and a cost effective strapping design methodology was developed to provide guidance to designers in preparing future hull strapping designs.
