Analysis of Underwater Repair Technology on the Jack-Up Platform Spud Can

Underwater welding has been used widely in construction and maintenance of off-shore facilities. With state-of-the-art equipment and fi ller 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 several advantages from the aspects of fl exibility and cost effi ciency, but some serious problems could emerge due to weld quality and safety of divers. In this paper analysis of applicable technologies of underwater repair of a jack-up platform spud can is made, including description of possible problems that may occur. Also, a comment on specifi c details of proposed techniques has been given and a comparative analysis of considered techniques focused on the economic and technological aspects of repair has been made
