Introduction The complexity and dimensions of marine and Arctic structures made of BCC low-alloyed steel are enormous, and the expanse of Arctic territories is such that it seems impossible to quickly provide assistance and repair in case of any accident, and this can lead to the loss of lives and an environmental disaster. Therefore, the safety of structures in service depends highly on the quality control system applied for the materials and the level of requirements, which 1.
