Overall

, we observe that the transport of fluids through pipes has almost been stagnant, since 1982. A similar trend was witnessed, from 1987 to 1997, for the deliveries made by ships or boats.

However

, there have been a lot of fluctuations in the amount of goods carried by railways or by road vehicles. On closer examination, we see that, in 1975, approximately 4,000,000,000kg of deliveries of materials were conducted by cargo ships and trains.

Nevertheless

Moreover

, before 1975, the transportation of liquids through the pipelines was less than 10 million tonnes. But,

this

number doubled during the 1980s, and after 1982 there was stability that was observed.

In addition

as a result

in 1974, more than 6,000,000,000kg of shipment was being done by trucks and lorries. Later in 1978, there was a small drop in

quantity, but during 1982-1990, and 1994-1997, the numbers were rising, where roughly 10 million tonnes of extra goods were shipped.
