国外海上登乘廊桥结构设计规范比对分析

Comparative Analysis of Classif cation Society Rules for Offshore Gangway Structure Design

海上登乘廊桥可对船舶艏摇、横摇、纵摇、升沉等运动进行补偿,保障人员安全,提高登乘效率。本文通过对挪威德国劳氏船级社(DNVGL)、美国船级社(ABS)、法国船级社(BV)关于登乘廊桥结构设计规范比对,研究各国规范对登乘廊桥分类、结构材料、设计载荷、典型工况及载荷组合、结构强度评估的具体要求,分析不同规范的异同,为我国海上登乘廊桥的设计开发提供参考和借鉴。

Offshore gangway can compensate ship’s yaw, roll, pitch and heave motion, ensure personnel safety and improve boarding effi ciency. By comparing and analyzing the structure design rules for offshore gangway that proposed by classifi cation societies, such as DNVGL, ABS and BV, this paper investigates the specifi c requirements of gangway categories, structural materials, design loads, typical load cases, structural strength assessment. The differences and similarities of these rules are summarized to provide references for the design and development of domestic offshore gangway.
