A tension leg cable is connected between a floating structure and a seafloor anchor means. The cable is a multi-strand cable having voids between adjacent strands. A fluid tight vulcanized rubber sheath is provided covering an outer surface of the cable. A fluid tight corrosion resistant tubular member surrounds said sheath so as to define an annular space between the tubular member and the sheath. Means is provided for supplying an inert gas under pressure to said voids and said annular space. Means is provided for monitoring the pressure of said inert gas in said voids and said annular space to detect changes in said pressure so as to indicate a leak in either said sheath or said tubular member. Methods of construction of said tension leg cable are also disclosed.
