内转塔单点系泊锚缆防弯器触底分析

Touchdown Analysis for Bending Stiffener on Mooring Line of Internal Turret Mooring System

针对某南海内转塔单点6号锚缆防弯器脱落的问题,对浮体在压载、半载和满载3种载况条件,分别在操作海况和极限海况进行锚缆防弯器的触底分析。结果表明,操作海况中如果风浪方向为东北向,则6号锚链防弯器会大概率发生触底现象,并且在极限海况下防弯器除了发生触底摩擦还会发生触底碰撞现象,防弯器脱落的可能性由于触底碰撞而增加。

Aiming at the bending stiffener disengaged from No.6 mooring line of internal turret mooring system,the touchdown analysis of bending stiffener on No.6 mooring line was conducted under both operation condition and extreme condition which ballast load condition,medium load condition and full load condition were considered.The results showed that there may have higher probability of occurrence of touchdown for bending stiffener on No.6 mooring line when the wave direction was northeast,and impact between bending stiffener and seabed can be observed in extreme condition,therefore it may have obviously higher probabilities in term of bending stiffener disengagement.
