A lecture by Dr William Craig: Marine Anchors: Development, Perceptions And Reality. The form of the marine anchor has changed significantly over the centuries – from primitive stone anchors and killicks, through classical stocked anchors used from Graeco-Roman times to the nineteenth century, to articulated, largely stockless, anchors and later to specialist units for small vessels and for the offshore engineering industry. The lecture covers these changing forms. It also looks at the images and analogies for anchors found in advertising, art, the navy, politics and religion over the centuries. The main focus is on developments from the nineteenth century, the growing impact of engineering and materials technology and the recognition and understanding of the mechanics of the interaction with the seabed. Dr Bill Craig substantially retired from his post as Reader in Geotechnical Engineering in the University of Manchester in 2011. A Chartered Member of both the Institution of Civil Engineers and the Society for the Environment, he is a past Chairman of the British Geotechnical Society. He has been involved with the offshore industries since 1976. Interest in anchors began when he worked with Exxon on the assessment of specialist marine drag anchors for offshore drilling platforms in the soft clay seabed of the Gulf of Mexico, while on sabbatical at the University of Colorado in 1989-90.
