The present research addresses the crack arrest in the submarine pipeline under internal pressure, axial force, and bending moment. The main purpose of the research is to consider tight-fit sleeves as a solution to crack arrest. The stress intensity factor criteria are used to describe the crack behavior. It should be noted that the cracks examined here are inclined through-thickness cracks, which the ABAQUS commercial software used to simulate them. Itchr('39')s noteworthy that Mode I fracture is dealt with, and the other fracture modes are omitted. The results show that the tight-fit sleeves, preferentially arrest the inclined cracks; so that the amounts of the stress intensity factors decrease for all the cracks except for the circumferential cracks to the extent that they become closed. As a result, their growth stops in practice; however, it best reduces the stress intensity factors by up to 65.36% at the circumferential cracks, and their amounts remain non-negative. Tight-fit sleeves create a pressurized region around the inclined cracks. This causes  that inclined cracks remain closed.
