Abstract: During the deep water offshore jacket construction, there are some tubular TKY joint welds are fatigue joints. This paper introduces the structural characteristics and assembly welding processing of fatigue TKY joint welds of deep water jackets. Combined with the requirements of the relevant code for non-destructive testing method, the technical requirements and acceptance requirements of visual inspection, magnetic particle inspection and ultrasonic inspection are summarized, and a reasonable testing process is formulated which can provide technical reference for ensuring the weld quality of TKY fatigue joint.
