Direct Embedment Vibratory Anchor

Abstract

A direct embedment anchor driven by vibration was developed for use in deep ocean mooring systems. The report describes the second generation anchor and the modifications required to evolve it from the prototype. Procedures for selecting anchor fluke size for different sediment conditions through estimations of anchor penetration and short-term holding capacity are given. Based on test results, the vibratory anchor can provide between 25,000 and 40,000 pounds of short-term holding capacity in a range of seafloor condition. Operational experience indicates that the anchor will be limited to deployment from anchored or dynamically positioned work platforms.
