单点系泊油轮动力响应试验研究

EXPERIMENT STUDY ON DYNAMIC RESPONSE OF SINGLE POINT MOORED TANKER

单点系泊采油装置因其机动性强、经济性好、投产早等特点 ,已成为我国海上油田早期采用的主要装置。分析了引起海上单点系泊油轮纵荡、横荡、升沉、纵摇、横摇和平摇 6个自由度运动的原因 ,讨论了油轮各个自由度运动对油轮上设备正常工作的影响。研究表明 ,纵荡、升沉和纵摇对油轮设备影响最大。为了求得油轮这 3个自由度的运动 ,对单点系泊油轮进行模型试验。单点系泊油轮在海浪中的运动规律表明 ,在 ω/ g/Lbp=2 .5处纵摇和升沉运动最大 。

The single point moored (SPM) tanker has the advantages of a high flexibility, a good economic efficiency and early operation, which makes it become the main equipment in the early production of offshore oilfields. The causes resulted in the six movements of surge, sway, heave, pitch, roll and yaw (six degrees of freedom) for the SPM tanker were analyzed. The effect of each movement on the operation of the devices on the tanker was discussed. It shows that surge, heave and pitch have a great effect on the normal operation of devices. In order to determine these movements, the simulation tests were made and the movement regulations of SPM tanker under sea wave were acquired. Some measures for inbihiting the movements of the tanker were put forward.
