Lightweight design of offshore platform marine Structures – optimisation of weight to strength utilisation of corrugated shell plating
Ships and Offshore Structures, 2012Co-Authors: Jonas W. Ringsberg, Hüseyin Sağlam, Asaduzzaman Sarder, Anders UlfvarsonAbstract:The structural weight of a shell-Plated Structure can be reduced in numerous ways. The current investigation presents an example of innovative lightweight design of the pontoon of an offshore platform by utilisation of corrugated Structure. Corrugated shell plating is compared with a conventional stiffened panel with respect to strength, weight and cost. For this purpose, an optimisation methodology is developed for shell-Plated marine Structures. The procedure enables the analysis/comparison of various (structural) solutions with regard to strength characteristics, weight and cost. Here, strength characteristics include ultimate tensile strength, buckling stability and fatigue life analyses. Linear elastic finite-element analyses are carried out to generate input to the structural characteristics studies, which involve several design criteria according to classification rules. The results show that in competition with the traditional stiffened panel, corrugated shell-Plated Structure can be used as the more lightweight design solution. It can be manufactured and installed at a lower cost. Finally, the structural strength characteristics analyses show that, when designed properly, ABS and DNV classification rules are fulfilled without compromising with the safety margins.

a numerical method for double Plated Structure completely filled with liquid subjected to underwater explosion
Marine Structures, 2017Co-Authors: Jun WangAbstract:Abstract The double-Plated Structure is extensively applied to the surface ships and submarines. Between the two plates there always exists liquid such as water or oil. When it is exposed to the attack by underwater weapon, the shock wave firstly hits the outer plates, and then it is transmitted into the internal liquid, subsequently to the inner plates. The mechanism in this process is so complex that has been a troublesome problem for a long time. In this paper, a numerical method is developed to solve this problem. The second-order doubly asymptotic approximations (DAA) is used to analyze the external fluid-Structure interaction (FSI) effect for the outer fluid field with the outer plates, and cavitating acoustic finite element (CAFE) is used to model the internal FSI effect. Results obtained by this approach show good agreement with results of the excitation problem of 3D fluid-filled shell by a plane step wave. Last, two experiments are implemented to validate the method. From the comparative results, it shows that the simulation results coincide well with tests.
