STRUCTURAL DEVELOPMENTS IN LARGE ENERGY CARRIERS

The structural problems which may be expected with ULCC and large LNG carriers are dependent to a large extent upon the efforts devoted to them at the design and planning stage. So, in discussing potential structural problems the mathematical techniques and tools for their identification and solution are also defined. The effect of IMCO regulations on tank size is seen to be largely responsible for the structural configurations currently adopted, while sheer physical size has given rise to reconsideration of structural maintenance problems. Vibration is also considered to be of particular importance in ships of this size. With regard to LNG ships, the loads arising from the sloshing phenomenon are discussed, while the complex stress analysis required for the spherical type free standing tank system is illustrative of the high level of structural development at the present time. Notwithstanding the very large and detailed simulation calculations at the design stage, the importance of the behaviour of the real structure is emphasized and the steps necessary to achieve adequate standards at the production stage are outlined. Finally, the importance of the human element in such complex technology cannot be overlooked.
