Offshore floating production units such as FPSO, FLNG, etc. are stationed at operation sites for many years without stopping operation. The mooring systems are provided as permanent positioning system for the floaters and are designed based on conditions that normally assume way longer than their actual service life. The offshore industry, nevertheless, has experienced higher than expected failure rates of mooring systems in the past.  Therefore, more robust and pertinent design requirements are desired. On the other hand, while operators demand more reliable design procedures, mooring analysis needs to be performed for numerous load cases on actual projects, which require enormous cost and resources for simulation and analysis. This has resulted in the need by the industry for more efficient mooring analysis procedures while maintaining the required safety.
