In order to ensure safe and reliable gas transmission, the natural gas infrastructure should be kept in an excellent shape to transport natural gas as successful in the next decades as in the decades behind. Extra challenges in this process are the liberalisation of the energy markets (reducing the amount of money available) and increasing legislation on safety (increasing the safety expectancy of society). The way Gastransport Services deals with these challenges is explained in this paper.

A probabilistic analysis is an approach that allows to identify whether if preventive, predictive and corrective maintenance practices are efficient for keeping the overall system safety. The implementation of methodologies that evaluate the maintenance plans are a way to improve existing programs. Promigas S.A. E.S.P. is a company that must guarantee the reliability and availability of its natural gas transmission systems to its consumers. Therefore, since 2009, the company has implemented reliability centered maintenance practices to achieve it. However, considering the current scenario of the natural gas in Colombia and according to the growth plans of the company, it is necessary to guarantee that the reliability and availability indexes remain close to 100%. To achieve the aforementioned objective, it is necessary to diagnose the current maintenance plan. We propose a hybrid methodology combining functional and probabilistic analysis to assess the maintenance plan of a natural gas transmission system, specifically a turbo-compressor power pack. The proposed methodology includes a new priorization method to identify and select critical components and its critical failure modes, through a qualitative functional and quantitative characterization of the subsystems that conform the turbo-compressor power pack. The probabilistic analyses were simulated for five time periods: one, three, six, nine and thirteen years. The results allow to conclude in terms of availability that while the maintenance plan is optimal for the first-time period, from the second time period the preventive and predictive maintenance practices must be optimized increasing resources or modifying the equipment intervention frequencies.

This article presents the history of the development — almost 80 years — of the gas transmission system (GTS) supplying the consumer with natural gas (NG) with a length of almost 200 thousand km. The authors present the structural integration of the successful historical experience in creating a large-scale natural gas transmission system with the prospect of building a liquefied natural gas transmission system on this basis. In addition, this paper aims to answer the following issues: the necessity of modernizing the GTS due to its deterioration and the need to increase the volumes of GHG supplies. The results of the analysis of high technologies of the rocket and aviation industries show the possibility of effective integration of the GTS with cryogenic transportation of liquefied natural gas (LNG) over distances significantly exceeding 10 km, which has been sufficiently developed at present. The authors rationalize the potential organizations interested in the implementation of the proposed integration.
