Hawaii Deep Water Cable Program, phase II : Cable catenary study

摘要

The "catenary" study for the Hawaii Deep Water cable (HDWC) Program is applicable to the environmental conditions that cable No. 116 will experience at the bottom of the Alenuihaha Channel. Based on the present limited knowledge of the bottom surface, the possibility that the cable may be supported off the ground by an outcrop or may hang between two outcrops or barrier reefs must be considered.This study is divided into two parts. The first part addresses itself to the bending radius of the cable in its rod-like curvature on the outcrops of the bottom. The second part relates to the mechanical fatigue life of the lead sheath when the cable is subjected to the action of the water currents producing the above mentioned cable movements.
