Batch Tracking System (BTS) is commonly found as pipeline operational real time functionality within operator companies’ control room. It tracks batches, offering amongst other information their volumes, positions and Estimated Time of Arrival (ETA). In order to reliably calculate those system outputs, BTS requires operational information like pressures, temperatures and flow rates, elevation profile, as well as some fluid physical properties, being the most important ones density and viscosity. This work aims to track the actual necessity of measuring those variables and to establish their impact on ETA in a 700km long South African multi-product pipeline network. Thus, the flow dynamic was analysed using a commercial pipeline flow simulator, where the network operational scenario was entirely reproduced and then variations of density and viscosity were introduced to track the effects on batches’ ETA, per pipeline segment. As a result of the study, which employed usual refined products such as petrol and Diesel, it was identified: (i) both variables played a relevant role on the ETA estimation requiring to be accurately determined, even though viscosity is the most relevant; (ii) viscosity showed a more predictable behaviour as flow resistance shall take place independently of the elevation profile; (iii) density was highly dependent of the elevation profile; and (iv) the biggest ETA accumulated variation verified was around 128 minutes (due to a variation of –20% in the viscosity value) and the lowest one around 4 minutes (due to a variation of –2% in the density value).

This paper examines the variety of corporate venturing activities in the pharmaceutical and life science sectors, identifies the range of initiators, motives and structures, and evaluates the potential opportunities for professional venture capital firms. On the one hand, pharmaceutical companies need to maintain the new product pipeline that has increased the demand for technology acquisition, and on the other, mergers and rationalization within the sector have resulted in a significant growth in technology divestment. Both trends have boosted corporate venturing activity. The study examines the venture activities of nine pharmaceutical firms, fourteen life science companies and seven corporate venture capital funds. The authors conclude that, while there is a wide range of venturing options, there is considerable confusion in the industry over ends and means. Specifically, many firms have failed to differentiate sufficiently between strategic, financial and operational goals, and have therefore created inappropriate forms of corporate venture.

The article addresses the issues of diagnosing the tightness of oil pipelines. Methods of monitoring and diagnosing the tightness of oil product pipelines are presented, their advantages and disadvantages are determined. A method and technical solution for the continuous monitoring of the tightness of an oil product pipeline is proposed. The theoretical justification of the proposed method for determining leakage based on a change in the dielectric constant of the soil is given.
