Abstract: The drill floor structure, which supports the drilling modules of the drillship or drilling unit, should not only meets the requirements of the operation function, but also restricted by the hull dimensions and weight control, and different design schemes should be developed quickly for comparison and selection in the preliminary design stage. Under this background, based on the secondary development function provided by NAPA Designer, a parametric design module of drill floor structure is compiled, which drives the creation and update of the parametric model of the drill floor through data interaction. In addition, various design schemes are quickly provided for comparison and selection, and furthermore, finite element models are exported for structural strength analysis. Through a real ship project, it has been proved that the parametric design method of drill floor structure based on NAPA Designer can reduce the user threshold and significantly improve the design efficiency.
