This standard is proposed and managed by the National Oceanic Ship Standardization Technical Committee (SAC/TC12). This standard was drafted by. China National Shipbuilding Industry Technology & Economy Research Institute, China Shipbuilding Industry Corporation, No. 218 Research Institute, Shanghai Overseas Takahashi Shipbuilding Co., Ltd., China Classification Society. The main drafters of this standard are Li Jun, Sun Yaogang, Wang Chao, Zhu Jiashuai, Tang Xudong, Ma Shuguang and Yang Qingxia. Self-elevating platform structure design method Load Resistance Factor Design Method1 ScopeThis standard specifies the structure classification, material selection, and design criteria for self-elevating platform structure design based on the load resistance coefficient design method. Design load, final limit state, fatigue limit state, unexpected limit state, and special considerations. This standard applies to the structural design of steel self-elevating platforms.2 Normative referencesThe following documents are indispensable for the application of this document.
