    Abstract

    As the offshore energy industry moves into deeper waters, it is tending towards cost effective anchoring systems as an alternative foundation solution. Dynamically installed anchors are torpedo shaped and can penetrate up to 3 times their length into the seabed by the kinetic energy obtained through free-fall.
    The project investigates the anchors' performance through novel field and centrifuge studies. Existing tools for predicting anchor embedment depth and subsequent holding capacity are rigorously analysed and uncertainties regarding the anchors' behaviour during installation and inclined loading are addressed. New design approaches have been developed and validated against the extensive data.
