Autonomous Subsea HVDC Cable Trenching ROV Model

Underwrite 1,500 kW heavy tracked subsea trenching ROVs combining cutting chains with 10-bar water injection hydro-jet swords (burying armored HVDC power cables 3 meters deep into stiff glacial boulder clay to protect against anchor dragging). Model subsea burial service contracts ($380k/km trenched), and equipment payback.
