| dc.description.abstract | An analysis of the variation of forces acting on the upper ball joint of a riser string due to drill ship motion and riser tensioner dynamics has been conducted. The analysis includes the effect of breakaway torque on the tensioner sheaves while assuming vessel and upper ball joint motion to be independent. General equations for the tensioner cable forces and for the forces exerted on the riser upper ball joint by the slip joint-tensioner system are derived and solved. The variation in tensioner cable forces is compared to data generated in field operations. Upper ball joint forces and their variation with time can be predicted for given vessel and riser motions. | en |
