Cable Route Engineering

This course is designed to give the student a basic skills package in cable route engineering and an understanding of the fundamental elements of the concepts involved in the installation of a cable in the marine environment.  It is divided into five basic sub-groups covering the topics involved with the design considerations, planning and engineering requirements of a marine cable installation.  It is not intended as a Route Engineers Manual but provides the basic knowledge for personnel to feel confident in the route they are designing.
