Availability of gas trunklines is barely enough for gas to be delivered to ultimate consumers. In order for you to watch a blue flame dancing on the stove burner, gas should flow from a gas trunkline to a gas distribution pipeline, and afterwards run through a household piping.
After gas has been extracted from the land or sea subsurface, it needs to be delivered to consumers. The length of gas pipelines and gas distribution networks multiply exceeds the circumference of the Earth.
Sea can go several kilometers deep. Laying a pipe at the bottom is a challenge. However, 6,000 kilometers of pipelines are laid at the bottom of the North Sea, some of which have been there for 40 years already.
