【Abstract】 The basic principles and the main procedure for appropriate configuration of drilling riser buoyancy modules are presented.Taking hard hang off model as an example,the axial motion performance of drilling riser is analyzed and the dynamic tension of the suspended riser is identified.Based on this,the method to determine the rational buoyancy factor is proposed and the case calculation and analysis are performed.The buoyancy module configuration method proposed in this paper and the related research conclusions can be used as references in the future engineering.更多还原
