LARGE WIRE ROPE MOORING WINCH DRUM ANALYSIS AND DESIGN CRITERIA

Flange splitting is the most common cause in mooring winch failure. Conventionally designed winches have failed on a number of occasions when sizes of about 3 " to 3 one-half " diameter wire ropes in lengths up to 10,000 feet were employed for mooring large construction barges and semi-submersible offshore drilling units. The authors have developed a method to calculate the flange thrust load and the barrel external pressure for winches using large diameter wire ropes. Also, a general guide for design and analysis of such winches and the effect of the lateral modulus of elasticity of wire rope on the reduction in the layer tensions is presented.
