Abstract
This report details work undertaken to add a general hull stiffener modeling capability to the Trident Modeller software application. The capability was designed after analysis of the way hull stiffeners are typically defined in ship construction plans. The resulting implementation allowed creation of stiffeners through a number of means including arclength measurements along the hull surface, equal spacing between reference curves on the hull surface, and importing the stiffener’s shape from external CAD definitions. The new capability was tested and exhibited a level of robustness on par with the existing Trident Modeller RMGScript modeling entities.
