Abstract
A set of requirements to the quality of welded joints, guaranteeing prevention of cyclic and brittle fractures should be satisfied, in order to provide service reliability of hull structures in off-shore platforms in the Russian shelf. The paper analyzes the problems, arising in application of foreign approaches to substantiation of these requirements, and suggests ways to solve these problems, based on the methods of physical modelling of fracture processes. Investigation results are implemented in standards and procedures of RF Register and are used in certification of materials and welding technologies for shelf structures.
Keywords: off-shore platforms, welded joints, stress raisers, cyclic strength, crack resistance
