Underwater welding has been used widely in construction and maintenance of off-shore facilities. With state-of-the-art equipment and filler materials it is possible to achieve high quality of welded joints, particularly if underwater dry welding is applied. On the other hand, wet underwater welding has a several advantages from the aspects of flexibility and cost efficiency but some serious problem could emerge due weld quality and safety of divers. In this paper analysis of applicable technologies of underwater repair of an jack-up platform spud can is made, including description of possible problems that may occur. Also a comment on specific details of proposed techniques has been given as well as comparative analysis of considered techniques focused on the economic and technological aspects of repair.
