Submarine cable installation and repair company Asso Group has chosen underwater vehicle guidance technology from Sonardyne for its expanding trenching fleet.The company, based in Greece and with operations globally, will install Sonardyne’s subsea Lodestar attitude and heading reference sensors (AHRS) on its trenching machines working across interconnector and offshore wind cable installation, protection and repair. Asso Subsea specialises in hard soil conditions using its fleet of shallow to deepwater trenchers. Using Lodestar’s on its trenchers will allow technicians to complete cable laying and burial operations efficiently, by maintaining a high level of situational awareness of the platform’s dynamics. In addition to AHRS, some wind farm project specifications can also require the use of an inertial navigation system (INS) on trenchers, in order to ascertain an accurate as laid position of their subsea cables.
