Maintenance and integrity management of hydrocarbons pipelines face the challenges from uncertainties in the data available. This paper demonstrates a way for pipeline remaining service life prediction that integrates structural reliability analysis, accumulated corrosion knowledge, and inspection data on a sound mathematical foundation. Pipeline defects depth grows with time according to an empirical corrosion power law, and this is checked for leakage and rupture probability. The pipeline operating pressure is checked with the degraded failure pressure given by ASME B31G code for rupture likelihood. As corrosion process evolves with time, Dynamic Bayesian Network (DBN) is employed to model the stochastic corrosion deterioration process. From the results obtained, the proposed DBN model for pipeline reliability is advanced compared with other traditional structural reliability method whereby the updating ability brings in more accurate prediction results of structural reliability. The comparisons show that the DBN model can achieve a realistic result similar to the conventional method, Monte Carlo Simulation with very minor discrepancy.

That reality, and in particular the (dynamic) objects of signs, are independent of our thoughts or other representations is a crucial thesis of Peirce’s realism. On the other hand, his semiotics implies the claim that all reality and all real objects are real for us only because of the signs we use. Do these two claims contradict, even exclude, each other? I will argue that both Peirce’s metaphysics and his semiotics provide a natural via media: a structural account of the openness of processes, featuring transitive relations, connects process ontology implicit in his evolutionary metaphysics and the relational, quasi-inferential features embodied in interpretational sequences of signs. It is shown that Peirce’s notion of a sign, its normative role and his account of the directional force of objects implies a sort of logical causality that supports the unity of objects. In this way sign sequences are able to relate flexibly sign use with contextually specified independent objects. That is to say, relational properties of object-oriented chains of interpretations provide sign users with a flexible, fallibilistic instrument able to capture by contingent identity relations (teridentity) of the identity of objects in changing situations.Includes: Comment by Francesco Bellucci (pp. 433–437).
