Abstract: A linear equation is mathematically derived for hydrodynamic forces on a marine riser under effects of free surface and floating-vessel motion using a velocity-potential method. It accounts for ...

Abstract: A systematic method of determining the design parameter values of two-point mooring (TPM) systems is presented. The conclusions of nonlinear stability analysis of horizontal plane slow motion ...

Abstract: Riser motions (acceleration and velocity) should be estimated for the determination of forces on the riser in waves. They are predominantly influenced by vessel motions. Previous analyses involving ...

Abstract: Extensive computer simulation and performance analysis and assessment have been carried out for the dynamic positioning control of a large, commercial ocean mining ship / pipe system, and selective ...

Abstract: A genetic algorithm based approach is presented for process optimal design in forging. In this approach, the optimal design problem is formulated on the basis of the integrated thermo-mechanical ...

Abstract: A static analysis procedure is formulated and implemented for the numerical determination of nonlinear static equilibrium configurations of deep ocean risers or mining pipes. This implementation ...

Abstract: This part applies the modeling and solution techniques discussed in Part I to the computerized steady-state deflection analysis of deep ocean mining pipe systems. For accurate analysis, a realistic ...

Abstract: Surface impact velocities and accelerations of a buoyant module released underwater have been analyzed. The associated equations of motion are presented. The analyses include the effects of ...
