Abstract: A need for reliable and uninterrupted overseas telephone communications required that the transatlantic cable (TAT 5) be placed in a secure position below the ocean floor where it could not be damaged. Loss of service over this vital link to Europe would be very costly to replace. A rocky coastal approach and rough weather conditions, present in the area of the shore cable terminal, posed problems in selecting the most practical and cheapest method to embed this cable. This problem was solved with the use of the Harmstorf Hydro-Jet method employing a bottom riding sled to jet the cable into and below the ocean floor. Approximately 7000-ft (2134-m) of cable was embedded 4-ft to 6-ft (1.2-m to 1.8-m) deep through a rocky Rhode Island beach. The article also includes a short synposis of the successful laying of TAT 6.
