... within the jacket structure, several parameters are analyzed: eigenfrequencies, DELs, fatigue damages. Moreover, the most critical joints for fatigue design and potential spots for crack initiation are identified. Wind/wave misalignment and multi- directionality are taken into account as well. First...

... and alignment is required on the cruciform joint, because it is difficult to align the abutting plates on the area. Sometimes, misalignment matter on the cruciform joints have happened, and it is difficult to fix the matter when the misalignment exceeds the tolerance standard. It causes the time consuming jobs...
