Investigation of AC and DC power distributions to seafloor mining equipment
The main goal of this paper is to study and compare different power distribution alternatives for subsea electrical components for deep-sea mining in the Norwegian Sea. Such application requires power delivery in the multi-MW range at water depth of more than 3000 m. Hence, AC (50Hz), DC, high frequ...
