The Caldwell team installed a new submarine hybrid cable across Vineyard Sound from the Town of Falmouth on Cape Cod to the Town of Tisbury on Martha’s Vineyard. The installed hybrid cable is a single cable that contains 3 power conductors, each 1240kcmil Copper, and 2 fiber optic cables, each with 48 fiber strands, which now provides redundant communication and electric services. The method of cable installation also included horizontal directional drilling (HDD) at each landing to avoid potential impacts to coastal and nearshore wetland resource areas.
Location: Falmouth to Martha’s Vineyard, MA
