TOP 12 Pipeline Engineering (Length ≥ 3000 km) - Updated Version

Length: The total length of the network exceeds 14000 kilometers.

Introduction: One of the largest and most important natural gas transmission systems in North America, it is the backbone of North American energy infrastructure.

Length: The total length of the system is approximately 8850 kilometers.

Introduction: The largest and most critical refined oil pipeline system in the United States. It delivers refined petroleum products such as gasoline, diesel, and aviation fuel from refineries along the Gulf Coast to densely populated areas on the East Coast of the United States, such as New York and Washington D.C. The system supplies approximately 45% of the fuel demand on the East Coast of the United States, and its safe and stable operation has a significant impact on the US and global economy (such as the shutdown event caused by the 2021 cyber attack).

Length: A network consisting of multiple main and branch lines, with a total mileage exceeding 8700 kilometers.

Introduction: The natural gas backbone pipeline network with the widest coverage and strongest pipeline transmission capacity in China.

Length: The total length of lines A, B, and C exceeds 7000 kilometers (approximately 1830 kilometers for the overseas section).

· Introduction: China's landmark energy cooperation project of the "the Belt and Road".

Length: The planned total length exceeds 5600 kilometers.

Introduction: Intended to transport natural gas from Nigeria to Morocco and ultimately connect Europe.

Length: The total length exceeds 4700 kilometers.

Introduction: Russia's strategic channel for crude oil exports to Asia.

Length: The total length of the main and branch lines is about 4000 kilometers.

Introduction: The world's longest transnational crude oil pipeline system, which transports crude oil from Russia to multiple European countries, is one of the key arteries of energy supply in Europe and has strong geopolitical significance.

Length: The total length of the completed water pipeline network exceeds 4000 kilometers.

Introduction: Libya's iconic giant water conservancy project extracts fresh water from the southern Sahara Desert and transports it to the northern coastal areas.

Length: Approximately 4128 kilometers in total.

Introduction: The plan is to transport natural gas from Nigeria to Algeria, connecting the Mediterranean market.

Length: Approximately 4107 kilometers in total.

Introduction: A key cross-border gas transportation corridor from the Arctic region of Russia to Germany.

Length: The total length of the completed system is approximately 3460 kilometers.

Introduction: Canada's core pipeline network for transporting oil sands crude oil to the United States.

Length: Approximately 3000 kilometers (Phase 1 has been put into operation).

Introduction: The energy artery connecting the East Siberian gas fields in Russia and Northeast China.

List status description:

As a refined oil pipeline system, the operation mode and strategic significance of the "colonial pipeline" are different from those of long-distance crude oil/natural gas pipelines, but its physical scale (length) and technical complexity make it fully qualified to rank among the top in the list of ultra long pipeline projects.

The list sorting has been adjusted based on the latest data.
