Abstract

Daar bestaan 'n sterk moontlikheid dat daar binne die volgende dekade drie pypleidings vir die kommersiële vervoer van brandstofprodukte van Suider-Afrikaanse hawens na Gautengprovinsie aangelê gaan word. Omdat pypleidingvervoer (1) die energiedoelmatigste vervoermodus is, (2) aansienlik goedkoper is as pad- en spoorvervoer, (3) heelwat veiliger is as spoorvervoer en veral padvervoer, (4) pad- en spoorvervoer- en infrastruktuurkapasiteit vir ander verkeer beskikbaar stel, en (5) minder onverhaalde eksterne koste (soos lugbesoedeling, geraas en verkeersophopings) as ander vervoermodusse tot gevolg het, behoort pypleidingvervoer (onderhewig aan grondige ekonomiese evaluering) as 'n bykomende vervoermodus tussen tenkwerwe in Suid-Afrika oorweeg teword.


Pipeline transport is unique among modes of transport in that the pipe, which facilitates freight movement, is both the way and the vehicle, and it is permanently connected to terminals, which facilitate freight storage. This feature makes it the only mode of transport that does not require any materials or goods handling. In view of the facts that pipeline infrastructure is extremely capital intensive and that it has an unprecedented longevity, pipeline transport enjoys the highest level of economies of scale of all modes of transport. This economy is subject to steady and enduring high levels of demand. It is also the only mode of freight transport of which the operations do not require a return journey, whereby joint cost due to empty running is avoided.
