Paper presented at the Third ISOPE Ocean Mining Symposium, November 8–10, 1999
Paper Number: ISOPE-M-99-004
... ABSTRACT: The ocean mining pipe connects the sea floor to the mining ship and remains suspended in hostile sea environment carrying nodule slurry. This pipe shows nonlinear behavior due to large deflection under hydrodynamic forces, due to waves, current, ship velocity, and ship-induced...

... on the seafloor. 2-D deflection and 3-D motions of a 5486-m-long (18,OOO-ftl articulated pipe system and buffer cau be controlled with elastic joints, axial dampers and the buffer at the bottom end of the pipe, and further with thrusters installed along the pipe, controlling the lateral den«tion and reducing...

... as the bending, stresses. The axial dampers slightly decrease the pipe deflection, while the elastic joints increase it slightly. The ship motion excites the horizontal (x-) and vertical (z-) motions concurrently of the pipe in its initial static equilibrium configuration, which is deflected by the ocean current...
