Pipelines offer a number of advantages, some of which are decisive, in relation to other transportation methods. These include:

Large-volume transportation (60 million liters per day, for example). Excellent safety , with fewer than two incidents per 10,000 kilometers of pipeline per year. Secure supply , unaffected by weather, operating 24/7/365. Cost efficiency for medium and long-haul transportation, with no need for handling operations. For comparison purposes, the average cost per metric ton per 100 kilometers is :   •  Pipeline: €1.8 to €2.1. •  Train (2,000 tons): €2.7. •  Barge: €2.7 to €4.1. •  Truck (38 tons): €4.1.

Pipelines are also the only method of supplying large centers remote from oil production and import sources. The best illustration is the supply of Paris and its two airports (Roissy and Orly) by the LHP pipeline.
