Underwater Site Surveying for Cable Installations.
Abstract
This study was performed to determine significant properties of nearshore and inshore underwater sites for submarine cable installation, the measurement accuracies required, and the hardware and techniques required to obtain data. The hazards to cables and the causes of cable failures are examined. It was found that all significant properties except seafloor and subbottom topography through sand can be measured to the required accuracies. Equipment is recommended that will perform to the required accuracies. It is recommended that: (1) this equipment be assembled into a site survey kit and evaluated; (2) the utility and accuracy of sonic methods of seafloor and subbottom topographic survey in the surf zone be determined; and (3) supplementary procedures be developed for the surf zone where sonic methods cannot be used.
