Topic 1. # of LEGs for a TLP ( 3 or 4 )
Comparing the initial tension (f) against overturning moment (Mmin) for 3-legged and 4-legged TLPs (Tension Leg Platform).
( Sample calc. )
● # of required wires corresponding to the maximum overturning moment
For a 3-legged TLP, when each leg consists of 4 wires, 12 wires are required in total.
For a 4-legged TLP, the max. tension can be reduced to 53%, each leg requires 2.12 (= 4 * 0.53) wires. With increasing the design strength per wire by 6%, the 4-legged TLP can be supported with only 8 wires.
