Field measurement of very large crude carrier (VLCC) mooring loads
In order to verify the prediction procedures used to design conventional mooring systems, a series of experimental studies was conducted at two tanker piers handling vessels up to 280,000 dwt. The force in each mooring line was monitored and recorded during the measurement period. Fender deflections and environmental conditions such as wind and current were also recorded. From the measured mooring line and fender force data, the resultant load acting on the tanker was evaluated. The resultant load was then compared with the design load based on the measured environmental condition. The tanker dynamic response when subject to natural wind was also recorded. Industry wind and current data are adequate in predicting the static wind and current load acting on a moored tanker. Analytical procedures based on theory and small scale model studies are applicable in prototype situations. However, more research is needed to understand the dynamic response of a moored VLCC while subjected to natural wind.
