Title: Design of a soft-seating lower anchor connector for snap load reduction in tension leg platform tethers

Abstract: 
Tension Leg Platform (TLP) is a type of offshore structure that is widely used in deep water oil and gas production as well as the foundation for offshore wind turbines. As a floating platform, the TLP has excellent stability in various wave conditions with very strict limitation in vertical movements while allowing horizontal movements to some degree. This is achieved by using taut mooring system with tendons (tethers) that hold
the platform down from its excess buoyancy and create a balance in vertical direction. In rough sea conditions, the tension load on tendons can vary greatly from zero to almost double the static pre-tension force in a short time, such an event is called a snap condition. Studies showed that brief periods of slacking do not itself damage the tendons but the snap load during re-tensioning poses severe fatigue to this crucial component of the TLP
