Marine Submarine Cable Installation > Our Expertise > Marine > Submarine Cable Installation Throughout our history, 91热爆has installed over 50 major subaqueous cable systems. We install power, telecommunications, and fiber optic cables throughout the Great Lakes, North America, and the Caribbean. RELEVANT PROJECTS BLOCK ISLAND The Block Island Wind cable project involved installing a 22-mile transmission cable from Rhode Island to Block Island, a six-mile export cable from Block Island to the offshore wind towers, and four inter-array cables between the five turbines. The power cables were buried six feet using a jet plow in up to 130 feet of water. All cable installation was performed successfully off of a dynamically positioned cable lay barge capable of precise auto-pilot navigation along the lay route. SAN FRANCISCO 91热爆has successfully installed three, 230 kV power transmission lines and two fiber optic lines in San Francisco Bay. A special barge was mobilized and assembled for the sole purpose of this project.聽 All cables were approximately 13,000 feet long and buried 3 meters. MCLEAN鈥橲 MOUNTAIN McLean鈥檚 Mountain Cable Project brought green power from Manitoulin Island to the power grid in Greater Ontario, Canada. The project required the installation of three, 115 kV power cables across the Little Current Channel. Each cable required shore entrenchments and were laid 2,000 across the bottom of the channel. LONG ISLAND REPLACEMENT CABLES This monumental installation extended from Norwalk, Connecticut to Northport, Long Island, New York. It involved the removal of seven existing oil-filled single conductor cables totaling 84 miles and the installation of three, new 138 kV subaqueous power cables. Each new cable was 12 miles long, 9-inches in diameter and weighed 70 lb/ft in air. The existing cables were removed throughout the winter months and the new cables were installed in the spring. CAPTREE ISLAND We installed a single 35 kV cable between Long Island and Captree Island, New York. The cable was approximately 13,000 feet, and was buried 6 feet into the bottom by our jet sled. The cable was shipped in a tub that weighed 250 tons. A special 1,000-ton capacity crane barge transloaded the cable from the delivery ship to the lay barge where it was set on top of our 550-ton turntable. IN ADDITION, WE OFFER THE FOLLOWING SERVICES: Budgetary and firm pricing Survey and design Route clearance Cable laying Cable burial Cable repair and splicing Cable locating Cable removal and salvage Shore end installations Special cable installation and handling equipment More services are listed in the聽 Marine Divison Cable Brochure Submarine Cable Installation Projects Submarine Cable Removal, Straits of Mackinac, MI Submarine Cable Replacement, Little Bay, NH Submarine Cable Installation, Pensacola, FL Getting Green Power to the Grid Redirecting Power Around San Francisco Block Island Wind Farm
