Conventional Anchor Test Results at Guam.

Abstract

The results of instrumented drag embedment anchor tests in Inner Apra Harbor, Guam are presented. The Navy can use this data for selecting and sizing anchors for Guam as well as other similar sites. Test data for the Navy STOCKLESS and STATO anchors are presented principally as plots of anchor penetration, holding capacity, and shank pitch and roll as functions of anchor drag distance. The STATO anchor performed erratically in Inner Apra Harbor due to the presence of a few feet of soft clay over a corally sand subsurface, whereas the STOCKLESS anchor with fixed fully opened flukes performed stably in similar conditions. Test results highlight the sensitive nature of high efficiency anchors to seafloor conditions and suggest the need for anchor proof setting in areas with layered or anomalous seafloor conditions.
