Electromagnetic Low-Energy Source System for AUV

Offentlig prosjektsammendrag

Prior to installations of subsea power-cables and offshore windfarms, the areas must be cleared for unexploded ordnances (UXO) dumped during and after the world wars. The detection of UXOs is typically done by towing magnetometers behind a surface vessel with short sail line separations. These surveys are expensive and takes a long time to perform. The oil and gas industry has deployed buried pipelines that can be challenging to detect for inspections not knowing their accurate position. In this project we will develop an active CSEM source for AUV that will enabling cost-effective UXO survey and a mean to detect buried pipelines effectively. Using an active CSEM source, the UXO surveys can be performed upto eight times faster than conventional methods with magnetometers, and the technology will enable simultaneous inspection and positioning of buried pipelines upto four times faster than using ROV's.
