According to the British Standard BS7448, the article presents a method to determine crack tip opening displacement (CTOD) and has evaluated the toughness of welded joints in offshore jacket structures (wall thickness is 90 mm) by this method. The results show that (1) it is excellent to evaluate the toughness of welded joint with the CTOD test, (2) the CTOD test can be taken as the acceptable test of welding craft, and (3) the particular offshore jacket structures tested no longer need heat treatment.
