摘要
参考挪威船级社海工规范要求,分析平台极限载荷状态下的总体结构强度.应用海工规范公式对主船体结构中的板和筋进行规范校核,对主船体双层壳内的环形梁进行屈服和局部屈曲的强度校核,对大的板架结构开展针对各种屈曲类型的校核,结果表明,该生活平台在目标海况下的结构承载能力满足船级社的规范要求.
The global strength assessment of the platform at the ultimate limit state is carried out in terms of the requirement of DNV offshore rules. The structural components of plates and stiffeners are verified by main scantling rule calculation formulas. The yielding and local buckling strength of various girders are evaluated directly by the calculated stresses. For critical big stiff- ened panels the various buckling modes are verified. All verification results fulfill the requirements of DNV offshore rules and the load-carrying capacity of the platform under the target environmental condition is satisfied.
