Abstract:

A cable shore landing protection system was needed at Southwest Bay, Ascension Island, to protect future cables coming ashore. Three subsurface conduits were installed from the shore out under the seafloor, using a lightweight horizontal drill rig. These three Directionally Drilled Boreholes range from 500 to 800 feet in length, and exit the seafloor at water depths of 35 feet or greater. These boreholes were installed in late August and early September of 2002. This effort took 13 days on site to accomplish.
