Tension Leg designs use high-tension mooring lines oriented vertically with anchors designed to withstand high vertical loads (e.g., suction pile anchors). The distance between anchors is approximately equal to the width of the floating platform, representing the minimum possible mooring footprint. These designs require a specific platform type with extra buoyancy. Youwind calculates the Tension leg mooring line length directly with the bathymetry. If the bathymetry is 100 the length of one line is 100 and if you have 4 lines, the total mooring line length is 400m.
