Some aspects of marine riser analysis
2010The problem of the static and dynamic analysis of marine risers is considered in this thesis. The equations of motion for a pipe conveying fluid are derived using a variational approach. The nonlinear expressions for the bending and torsional curvatures are obtained for a beam undergoing finite rotations. The elastic strain energy is expressed in terms

Brittle Fracture of a Marine Riser Clamp
1992Abstract An API type 2 steel clamp located on the riser of a semisubmersible drilling rig between the lower ball joint and riser blowout preventer (BOP) conductor failed after 7 years of service. Failure analysis revealed the cause of failure to be the low toughness of the clamp material.

Static and dynamic analysis of marine riser
2004The analysis is concerned with static and dynamic behaviour of the explorational marine riser exposed to the sever environmental conditions. The most significant influence factors that can exert the loads on the riser structure are taken into account. The static analysis is based on a nonlinear mathematical model.
