The purpose of the survey was to determine the degree of protection provided to the cables based on the burial depth into the seabed, i.e. the seabed cover over the cables along the cable route in all positions along the route where a survey was practically possible. The cable burial depth below the existing seabed and the bottom position of the cables (x, y) were then to be presented in a survey map, upon completion of the survey. The report in this series details the survey, including equipment, methodology, data processing steps and recommendations with regards to further protection.
