Development of a hull generation method based on FORMDATA systematic series

02/12/2020

Hull design is an important, demanding, and time-consuming component of ship design. Improving hull design and making it an easier task, by developing tools that can be used in the preliminary steps of ship design to quickly generate one or several hulls, could have a significant impact on the ship design process. Developing the method for such a tool has been the primary objective of this project. A program was developed to test this method, using the MATLAB software, to create a FORMDATA hull through modelling based on hull parameters (e.g. slopes, number of sections, length of parallel middle body). Using this hull model, new hulls can then be generated by modifying some of the parameters, giving freedom to the designer to experiment with alternative solutions and allowing for a better hull development. The program also provides the designer with more information about the generated hull, leading him to a better understanding of the constraints and determinants of each generated hull. Several hull solutions were tested. The results showed a rather satisfactory performance of the method and met the initial objectives of the project, thus opening new perspectives on the use of FORMDATA models in hull design. A relevant intermediate result of the project is the digitalisation of coordinates of the FORMDATA series sections, previously only available in raster format, thus allowing for an easier future use of this data by hull designers or researchers.
