摘要：Admittedly, very large floating structures have huge size with coterminous modules and more than one kilometer in longitudinal direction, whose intact stability is different from any other normal ships and offshore platforms. In this paper, very large floating structures are connected with several modules in case of rigid. Based on the intact stability in calm water, vertical moments are analyzed from wave factors including lengths, heights (the ratio of height to length), directions and locations of the chest. Finally, research on intact stability is briefly reviewed. Due to rigid connected modules, very large floating structures have the same displacement and rotation as the unit module, and also have the same metacentric and large angle stability. However, with increasing the numbers of modules, maximum vertical moments are accordingly rising with wave factors as length, heights (the ratio of height to length), directions and the locations of the chest, and the metacentric and large angle stability are also differ from the static stability. ?, 2015, The Editorial Office of Shipbuilding of China.
