Abstract

Jack-up is a type of movable offshore structure that comprises of foundation, leg and hull. Its analysis requires finite element analyses to generate a reliable structural responses under different geometrical configurations and loading types, especially during the conceptual phase. In this phase, the objective is to seek a vigorous and economical structural configuration. This paper presents the application of an object-oriented approach in developing finite element software for jack-up analysis within the MATLAB environment. The objective is to update the cycle of data preparation and analysis. In this finite element tool, with a simple command, any changes in the jack-up element such as material, basic geometrical dimensions and loading types are easily changed. This paper also provides a further illustration of the usefulness and potential of the object oriented perspective. A detail discussion of the structural analyzer sub system with regard to structural optimization and structural design has been additionally specified. Examples are given for application for creation of different configurations of jackup structures.
