 Email: Ractliffe@TensionTech.com- Dr. Alan Ractliffe is a founding director of TTI. He is a former academic, with almost 20 years experience in the Department of Naval Architecture at the University of Newcastle upon Tyne, one of the largest of its kind in Europe. - His early specialisation in structural strength behaviour broadened into a wider range of interests in computer modelling of dynamic problems in the marine environment, including cable dynamics, pipe-laying, towing, and motions and forces on floating bodies. His experiences in these varied fields involved the application of basic principals and exploitation of research, leading to state-of-the-art software. - Dr. Ractliffe is the principal developer of TTI's Optimoor mooring analysis computer program. He has also conducted dynamic analyses of riser protection nets and towing systems. - (January, 2002)
