GUIDELINES FOR DEEPWATER PORT SINGLE POINT MOORING DESIGN

This report provides guidelines for the establishing of design mooring loads for SPMs (single point moorings) and for the design of mooring components of SPMs. It first discusses the manners in which waves, winds, current, the tanker, and the mooring system influence mooring loads. It then describes how mooring loads should be determined through model testing and statistical analysis. Next, it discusses how the arrangement and strength of mooring fittings on tankers may limit the maximum allowable mooring loads. The report then discusses the properties of the synthetic ropes normally used as mooring hawsers and recommends factors of safety for SPM hawsers. It also discusses the rules and standards which should be used for mooring structures, anchor chains, bases, and piles. Next, the report discusses synthetic-rope testing and field inspection. The report ends with recommendations for further investigation of large-diameter synthetic rope properties, testing, and inspection. The report contains an extensive glossary of SPM terminology and a bibliography of other reports and articles in the field of SPMs. (Author)
