Hawaii Deep Water Cable Program, phase II-C task 8.4 : environmental design criteria for cable deployment operations in the Alenuihaha Channel

Abstract

In September 1983, Edward K. Noda and Associates prepared a report entitled ''Evaluation of Expected Operational Wind, Wave and Current Conditions in the Alenuihaha Channel Related to the Design Criteria for the Cable Laying Vessel for the Hawaii Deep Water Cable Program". This study established preliminary deployment criteria based primarily on theoretical/empirical models, since at that time there were no long-term direct field measurements of winds, waves and currents in the Alenuihaha Channel. As part of the Hawaii Deep Water Cable Program (HDWCP), field programs were initiated to acquire data within the channel to enable more realistic assessments of the expected environmental conditions for design and deployment of the deep water cable. This report provides a re-assessment of the operational wind, wave and current criteria for deployment based on the data acquired to date. Field programs are still on-going, and thus, further refinement of the deployment criteria may be required in the future with the acquisition of additional data.
