THE VANCOUVER ISLAND TRANSMISSION REINFORCEMENT (VITR) PROJECT

7 6 5 4 3 2 1

Project Overview:

Caldwell Marine International, LLC. successfully installed 87,500 meters (54.4 miles) of high voltage submarine power cable in Vancouver, British Columbia. The $295-million VITR project replaces an aging 135 kV transmission cable with a new 600MW-242kV system, providing Vancouver Island and the Southern Gulf Islands with safe reliable energy to meet their needs far into the future. Under contract with Mitsubishi International, work included marine route survey operations, cable route engineering, freighting of 6000+ metric tons of submarine cable from Japan to Vancouver, submarine cable installation from Caldwell Marine International’s Dynamic Positioning (DP-II) cable lay barge, ROV touchdown monitoring, and specialized low-impact submarine cable laying through environmentally sensitive Eel Grass (Zostera marina) beds.
