Hawaii Deep Water Cable Program, phase II-D task 4 : abrasion-corrosion studies

Abstract

This Final Report is the combined report for two separate, but closely coordinated research efforts, one conducted at Georgia Institute of Technology and the other at the University of Hawaii. During the course of data evaluation it became apparent that combination of the results was both desirable and necessary, thus the combined report. An assessment is presented of the possibility that the Hawaii Deep Water cable may be damaged due to abrasion or abrasion-enhanced corrosion. The sites of potential damage are the several steep scarps in the deep water section of the Alenuihaha Channel. It is anticipated that during deployment the cable may become suspended between ledges and moved back and forth by the daily tidal currents.
