Title:
Embedment Anchor Siting, Installation, and Holding Capacity Verification
Report Date:
1976-08-01
Abstract:
Several concepts for the verification of embedment anchors are described. The concepts verify different phases of the anchor fluke embedment and keying. The verification technique used will vary with the specific application and environment. Moderately loaded anchor flukes in a seafloor known to be homogeneous can be verified to a satisfactory degree by indirectly measuring the fluke penetration using a 12 kHz pinger attached to the anchor line near the seafloor. In seafloors of suspected heterogeneity, a 3.5 kHz pinger similarly attached would be necessary to indicate the layer thicknesses to enable satisfactory prediction of holding capacities. Critical, heavily loaded anchor flukes, especially when in heterogeneous seafloors, will require proof loading to design load for satisfactory verification and may require, in some cases, installation and pull-out of a test anchor.
