Marin Mätteknik Statnett and National Grid North Sea Network Survey Project


Sub-contracted through NetSurvey to provide Marin Mätteknik AB with specialist multibeam personnel onboard the MV Franklin for the North Sea Network Survey project. This project aims to construct a High Voltage Direct Current (HVDC) electrical interconnector between Norway and the UK. The link would make it possible to combine the hydro-based power system in Norway and the thermally-based generation system in the UK. The corridor survey will provide bathymetric, geophysical and benthic information along the entire 711km proposed cable route. A MacArtney Focus-2 ROTV has been fitted with a dual R2Sonic 2024 multibeam system, together with an iXSea ROVINS inertial navigation system for work in the deeper water. Very high-resolution bathymetry surveys were conducted using the QINSy software package for initial data acquisition and processing, with Fledermaus used for cleaning, surface generation, and visualization.
