Installation of a Submarine Fibre Optic Cable

Ketchikan Public Utilities proposes to install a submarine fibre optic cable between Ketchikan, Alaska and Prince Rupert, BC. The proposed route of the cable is approximately 160 km in length, of which approximately 60 km are within Canadian waters. Landing stations are proposed on Ridley Island in Prince Rupert and Mountain Point in Alaska.

Installation of the cable will be facilitated by cable laying marine vessels travelling at speeds of less than 2 knots. The roughly 5 cm diameter cable will be placed directly on the surface of the ocean floor. No trenching, jetting, or ploughing to bury the submarine cable is proposed. A small boat and divers will be used to place the cable through the intertidal zone and onto shore, where it will be connected within a precast, concrete cable vault located above mean high tide. Intertidal sections of the cable near the landing stations will be protected within cast iron, articulated split pipe and covered by rock-filled gabion mats.

Installation is anticipated to take place over several weeks during summer.
