This chapter presents a critical analysis of the existing procedures, described and commented in [1], proposed for the design of the reinforcing wraps/leeves, made of composite materials. These wraps are applied in the areas with volumetric surface defects (VSDs, also named local metal loss defects) of the transmission pipelines, intended for hydrocarbons (petroleum, liquid petroleum products, natural gas, liquefied petroleum or natural gas) or other fluids (water, ammonia etc.). The procedure developed by the authors is selected and the results of its application for the design of the composite materials reinforcing wraps, applied in the areas with VSDs of transmission pipelines, are analysed. The present chapter also highlights the technical requirements regarding the definition and qualification of the pipelines repair systems using composite materials and the information, which must be made available as input data for the design of the reinforcing wraps, intended for various practical applications (repair of pipelines with different locations, shapes and dimensions of VSDs). The issues discussed and the solutions formulated in the following can be useful both to the providers or manufacturers of the components of the composite materials repair systems and to the ones dealing with the design and execution of the maintenance works for the pipelines, belonging to the transmission systems of hydrocarbons or other fluids.
