      Dr Isabel Ridge joined Tension Technology International as a consultant in October 2007. At University, Isabel studied Mechanical Engineering, and first started working with ropes in 1987 when she undertook her final year project to design and manufacture equipment for investigating the combined bending-tension fatigue loading of wire ropes. She was awarded the Institution of Mechanical Engineers project prize for this work. Following on with continued studies in this field, she completed her PhD thesis, ‘Bending-tension fatigue of wire rope’ in 1992, for which she was later awarded the OIPEEC Prize for a contribution to rope research by a young researcher.

      After completing her ‘formal’ education at the University of Reading, Isabel remained working there in the Rope Research Group, on numerous rope related project and studies. One such project led to the award in 1994 of the Worshipful Company of Turners Design Prize Silver Medal for her design of ‘Equipment for the interactive fatigue testing of wire rope’. During the subsequent years, Isabel rose to the position of Principal Research Fellow and Manager of the Rope Research Group.

      Isabel has developed a strong background in the field of ropes for offshore applications, particularly in the safety critical area of deep sea moorings for oil platforms. She has unparalleled experience of testing, condition assessment and prediction of service behaviour in this field. More recently, her research has developed a better understanding of the torsional properties of the various types of mooring components in use (both wire and fibre ropes as well as chain) and allowed prediction of the way in which they interact. This knowledge has led not only to improved installation procedures, but has allowed operators to avoid system configurations which would lead to poor service compromising system integrity.

      Isabel left academia to work in industry in 2005 when she joined CASAR Wire Rope (Kirkel, Germany) as Head of Research and Development. During her time there, amongst other projects, she was chiefly responsible for developing a new generation of ‘composite’ ropes which effectively combine high strength aramid fibres with steel strands. Such light-weight high-strength ropes are of great commercial value to various industries (such as offshore and deep mining) where long lengths of rope are employed and weight becomes a critical factor.
