A purpose built computer controlled test rig was constructed at Abington, designed by TWI's Martin Ogle. It was used for multi-axial loading tests - to buckle and bend tubular specimens. This rig can produce forces up to 2500kN in axial loading, 1200kN in shear loading and 660kNm in in-plane bending. Tubular specimens simulating offshore jacket legs, with diameters in excess of 0.3m were fabricated and crushed and bent through angles up to 45°.
TWI has been involved in all developmental and in-service aspects relating to oil platforms, working with the industry from cradle to grave.
