Static Analysis: Catenary Cable Cable configuration: Tension along the cable: T H w T = T + h r g Az s = sinh x H + ( + ) T H T T z = s z - h = H cosh x - 1 T H T T H ϕ ϕ W ϕ O = 0 x B x h Anchor z x Seafloor s Image by MIT OpenCourseWare.
Catenary Solution ⎯⎯ Key Results (without Elasticity) • Minimum line length required (or suspended length for a given fairlead tension) for gravity anchor: 1 2 2 T max l min = h wh 1 • Horizontal force for a given fairlead tension: T H = T wh • Horizontal scope (length in plan view from fairlead to touchdown point): wl min x = T H sinh 1 w T H • Vertical force at the fairlead: T z = wl min
