Results of the research aimed at the development of the basic criteria and principal methodological approaches to the calculation and design that underlies any repair undertaking associated with the restructuring of engineering networks through the application of a polymeric sleeve. It is noteworthy that the pipeline material and the degree of its deprecation, identified on the basis of the residual pipe thickness, the length and the diameter of each pipeline section being repaired, the media pumped into the pipeline, the adjacent ground and subterranean infrastructure, the presence of any subterranean waters and other factors are to be considered in each specific case.
A software programme designated for the calculation of the durability of double-layer structures of pipelines connected to polymeric sleeves has been developed. The software makes it possible to consider a wide range of properties of a polymeric sleeve to identify its behavior driven by any alterations in the input information, and to select the most economical and technologically efficient option within the limits imposed by the durability-related requirements pre-set in the design.
The ultimate objective of the software programme is to assess the applicability of the trenchless repair method involving a polymeric sleeve in each specific case by taking account of the environment and the condition of the pipeline. The software is also capable of developing the requirements to be fulfilled by subcontractors in order to assure the appropriate quality of any repair work performed and the reliability of any pipeline sections repaired.

The problem of potable water supply is becoming increasingly relevant. This problem is particularly important in the countries of Oceania, where neither surface, nor subterranean water is unavailable due to the harsh terrain and climate. Therefore, construction of marine water intake structures is the only solution. Peculiarities of construction of water intake facilities and their operation in the environment of the Pacific Ocean are considered by the author. The author provides his layout solutions of water intake structures. The author has given up the idea of a water intake facility capable of taking water from the channels because the sand brought by the waves from the bottom may inflow into the water inlet structure. Besides, channels drain in the low tide period; therefore, water intake facilities remain idle.Also, high aggressiveness of the sea water constitutes another problem. The sea water may damage any water intake structure, as some of their elements are made of reinforced concrete, while others are made of steel. Steel corrosion resistance may be improved by alloying additives (chromium, Nickel, copper, etc.), or, alternatively, by a zinc and aluminum coating which must be 120—250 microns thick.
