Disadvantages of pipeline transport
Answer Text: Disadvantages of pipeline transport:(a) Selective in that they can be used to transport fluids and gasses and can transport only one type of commodity at a time.(b) Insecure in that they may be sabotaged if they run across a number of countries when there are political differences or when one country decide to withhold the product.(c) Pipelines may cause pollution if they burst spilling oil, gas or sewage and the problem would be grave if it occurred under water.(d) Inflexible in that they remain permanently in one position and rerouting becomes impossible and further distribution of the substance from depots has to be done by roads and railways.
