Drag Embedment Anchor Tests in Sand and Mud
Abstract
This report provides the results of conventional temporary and permanent mooring anchor tests in dense fine sand at Port Hueneme and normally consolidated silty clay at Indian Island, includes a preliminary analysis of the data, and provides suggested modifications to improve anchor performance. The data provided can be used to quantify anchor capacity, to guide anchor selection, to improve the understanding of anchor behavior, and to guide the formulation of empirically and theoretically founded schemes to define anchoring capacity. Although the number of tests performed on each anchor during the recent anchor tests in sand and mud was limited, the repeatability of the data was excellent and correlations with previous NCEL tests provided added insight into the specific behavior of the tested anchors and into general and chain behavior. Data for the Two-Fluke Balanced, STATO, MOORFAST, BRUCE Twin-Shank, STEVFIX, PRISMA, and WISHBONE anchors are presented principally as plots of anchor penetration, holding capacity, and shank pitch and roll as functions of anchor drag distance.
