Overview
How energy moves — the full supply chain
Energy is produced concentrated in specific geographic locations and consumed distributed across populations. The gap between these two facts is bridged by one of the most capital-intensive and sophisticated transport networks ever built by humanity. A barrel of Saudi crude oil may travel 7,000 nautical miles on a 300,000-tonne tanker, pass through Hormuz, traverse Malacca, offload at an Indian refinery port, be refined into diesel, loaded onto a tanker truck, and delivered to a petrol station — before a single litre is used. This section documents every component of that system.

Oil tankers — vessel classes
Every class of oil tanker — from ULCC to coastal tanker
Oil tankers are categorised by their deadweight tonnage (DWT) — the weight of cargo they can carry. The Worldscale tanker classification system is universally used. Key classes from largest to smallest:
Crude oil carrier · Largest class
ULCC — Ultra Large Crude Carrier
ULCCs are the largest ships ever built. The largest ship in history was the Seawise Giant (Happy Giant / Jahre Viking) — launched 1979, 458 metres long, 260 m beam, 564,763 DWT, carrying approximately 4 million barrels. Sunk during the Iran-Iraq War (), salvaged and scrapped . No ULCC of comparable size operates today — the largest current VLCCs are approximately 380m. ULCCs cannot transit any major canal (too large for Suez, Panama, or Turkish Straits) and can only berth at very deep-water ports (Ras Tanura, Kharg Island, Fujairah).
DWT
320,000–564,000+
Length
380–458 m
Cargo
~2.5–4 M bbl
Draft
~24 m loaded
Named example: Seawise Giant (458m, 1979–2010) — largest ship ever built · GPS 26.65°N 50.16°E (Ras Tanura berth)
Crude oil carrier · Most common large class
VLCC — Very Large Crude Carrier
VLCCs are the workhorses of global crude oil trade. A single VLCC carries approximately 2 million barrels — equivalent to about 12 hours of global oil consumption. Approximately 600–700 VLCCs operate globally. They travel at approximately 14–15 knots (26 km/h). A round trip from the Persian Gulf to China takes approximately 45–55 days. Cannot transit the Suez Canal fully loaded (maximum Suezmax can transit). The benchmark freight rate for VLCCs (the Worldscale rate) is published daily and directly affects the landed cost of oil in importing countries.
DWT
200,000–320,000
Length
~320–340 m
Cargo
~2 M bbl
Speed

Route example: Ras Tanura (26.65°N 50.16°E) → Vadinar India (22.47°N 69.87°E) · 45 days round trip · 7,500 nm voyage
Crude oil carrier · Suez transit
Suezmax
The largest tanker class that can transit the Suez Canal when loaded. Named for the Suez Canal maximum — which was widened in 2015 to allow approximately 200,000 DWT fully loaded. Typical cargo: approximately 1 million barrels. Suezmax are the dominant vessel class for trade between West Africa, the North Sea, and Europe. Major routes: Nigeria → Rotterdam, North Sea → USA East Coast, Black Sea → Mediterranean.
DWT
120,000–200,000
Length
~270–290 m
Cargo
~1 M bbl
Draft (max)
~20.1 m
Route: Bonny Light Nigeria (4.29°N 7.14°E) → Rotterdam refinery (51.90°N 4.30°E) · 14 days · 5,500 nm
Crude oil carrier · North Sea / Baltic
Aframax
The dominant tanker class in the Baltic Sea, Black Sea, Mediterranean, and Indonesian region. Aframax are versatile enough to enter most ports — their 80,000–120,000 DWT and ~14m loaded draft allows access to shallow-water terminals. Named after the Average Freight Rate Assessment (AFRA) scale. Russian Aframax fleet became critical after Western sanctions forced Russian crude (Primorsk, Ust-Luga) to use non-Western insurance — a large "shadow fleet" of Aframax emerged from onwards carrying Russian crude to India and China.
DWT
80,000–120,000
Length

Cargo
~600,000 bbl
Draft (max)
~14.9 m
Route: Primorsk Russia (60.37°N 28.75°E) → Rotterdam · via Danish Straits 55.61°N 10.56°E · 6 days
Products tanker
LR2, LR1, MR — Products Tankers
Products tankers carry refined petroleum products — diesel, petrol, jet fuel, naphtha — rather than crude oil. They have coated, compartmentalised tanks to prevent contamination between product grades. Key classes: LR2 (80,000–120,000 DWT, carries jet fuel Asia–Europe), LR1 (55,000–80,000 DWT), MR (25,000–55,000 DWT — the most common, carries gasoline and diesel from refinery to distribution terminals). India's major oil marketing companies (IOC, BPCL, HPCL) use MR tankers to distribute refined products from coastal refineries to inland terminals. Singapore is the world's largest bunker (ship fuel) supply hub, served by MR tankers from Jurong Island refinery.

Dry bulk carrier
Capesize / Panamax — Coal and Iron Ore
Bulk carriers transport solid energy commodities — primarily coal (thermal and metallurgical) and also grain, iron ore. Capesize (180,000–400,000 DWT) are too large for the Panama Canal and must go around Cape Horn or Cape of Good Hope. Named for this route. They carry Australian Bowen Basin coking coal to Japanese steel mills and Powder River Basin coal to Asia. Panamax (60,000–80,000 DWT) fit through the original (pre-2016) Panama Canal. Handymax (40,000–60,000) are the most versatile class. A Capesize loading at Newcastle Australia (32.93°S 151.77°E) carries approximately 170,000 tonnes of thermal coal to China — approximately 3 weeks voyage.
Capesize DWT

LNG carriers and gas vessels
LNG carriers, LPG tankers — how gas travels at sea
Gas carrier · Most complex vessel class
LNG Carrier (LNGC)
LNG carriers are among the most technically complex ships ever built. They transport natural gas cooled to approximately −162°C, at which point it liquefies and occupies approximately 1/600th of its gaseous volume. The cargo tanks must be perfectly insulated — a 1°C temperature rise causes approximately 0.15% of the cargo to "boil off" to gas. Early carriers vented this boil-off; modern vessels use it as fuel (DFDE — Dual Fuel Diesel Electric) or reliquify it. Two main tank types: GTT membrane tanks (thin corrugated steel liner inside insulated hull — used by most modern carriers), and Moss-type spherical tanks (freestanding spheres — visible above deck as large white domes, older design). World's largest LNG carriers are the Q-Max class (266,000 m³, Qatar-specific) and Q-Flex (210,000 m³) — too large for any canal except post-Panamax locks.
Capacity
135,000–266,000 m³
Temp

Cost
~$250–300 M
Fleet

Named example: Al Gharrafa (Qatar, GTT membrane, 215,000 m³) · Route: Ras Laffan (25.91°N 51.56°E) → Dahej India (21.74°N 72.60°E) · 7 days
Gas carrier · Propane/Butane
VLGC — Very Large Gas Carrier (LPG)
VLGCs carry LPG — propane and butane — used for domestic cooking (India's LPG cylinders) and petrochemical feedstocks. Cargo is stored under pressure at ambient temperature, or refrigerated. Capacity typically 80,000–90,000 m³. India is the world's largest LPG importer — approximately 14 million tonnes/year — primarily arriving from Saudi Arabia (Saudi Aramco's VLGC fleet) and the USA. A single VLGC delivers approximately 44,000 tonnes of LPG to India — enough for approximately 3 million 14.2 kg domestic cylinders. Indian LPG import terminals: Kandla (23.00°N 70.22°E), Haldia (22.06°N 88.10°E), Mumbai JNPT (18.96°N 72.95°E).

Floating LNG infrastructure
FSRU — Floating Storage Regasification Unit
An FSRU is a converted or purpose-built ship that functions as a floating LNG import terminal. It receives LNG from carriers, stores it in its insulated tanks, and regasifies it (reheats the LNG back to gas) for delivery into the onshore pipeline network. FSRUs can be deployed in 12–18 months — far faster than building a land-based terminal (5–10 years). Cost: approximately $200–300 million for the vessel, plus mooring infrastructure. They proved transformative after Russia cut gas supplies to Europe in 2022 — Germany commissioned four FSRUs in under 12 months (Wilhelmshaven FSRU, 53.52°N 8.15°E, Germany's first LNG terminal), deployed within weeks of the political decision. India has one FSRU (Kochi). Pakistan, Bangladesh, and Jamaica have deployed FSRUs as rapid-response LNG infrastructure.

Named example: Neptune (Wilhelmshaven, Germany, 53.52°N 8.15°E) — Germany's first LNG terminal, commissioned December 2022 in response to Russia gas cutoff
Offshore production infrastructure
FPSO, drillships, rigs — production at sea
Offshore production · World's largest ship
FPSO — Floating Production Storage Offloading
An FPSO is a floating vessel that processes oil or gas extracted from a subsea well, stores the product in its own tanks, and offloads it periodically to a tanker. FPSOs are preferred in deep water where fixed platforms are impractical and pipelines are too expensive. They can be repositioned when a field is depleted.
Shell Prelude FLNG (GPS: 13.98°S 123.35°E, Browse Basin, Australia) is the world's largest floating object ever constructed. Dimensions: 488 metres long, 74 metres wide, 260,000 tonnes displacement — longer than four football pitches. It processes natural gas directly on the vessel, producing LNG, LPG, and condensate. Capacity: approximately 3.6 million tonnes LNG/year. Commissioned . Cost: approximately AUD 17 billion. It is also the world's largest LNG plant of any type by some measures.

Offshore drilling · Deepwater
Drillship and Semi-Submersible Rig
Drillships are self-propelled ships with a drilling derrick amidships. They use dynamic positioning (GPS-guided thrusters) to hold station above the wellhead without anchors — which is impractical in 3,000m water depths. Drillships can operate in up to 3,658m water depth (12,000 ft). Cost approximately $700 million to build, $400,000–$700,000/day to charter. Semi-submersibles (semi-subs) are partially submerged pontoon-supported platforms — stable in heavy seas, anchored or dynamically positioned. They operate in up to 2,000–3,000m depth. The Deepwater Horizon (GPS 28.74°N 88.37°W, Gulf of Mexico, BP operated) was a semi-submersible rig — it exploded in , killed 11 workers, and caused the largest accidental marine oil spill in US history (approximately 4.9 million barrels over 87 days before the well was capped). The disaster reshaped offshore drilling safety regulations globally.

Offshore drilling · Shallow water
Jack-Up Rig
A jack-up rig is a mobile drilling platform with three or four extendable legs that it lowers to the seabed — "jacking up" its hull above the water on those legs. This makes it a fixed-in-place platform while drilling. Maximum depth: approximately 100–170 metres water. Jack-ups are used for exploration drilling and well workover in shallow continental shelf areas. They are towed by tugboats to their location and take approximately 12–24 hours to "jack up." Approximately 450 jack-up rigs operate globally. Major jack-up areas: Arabian Gulf, North Sea, Gulf of Mexico, Bay of Bengal, South China Sea. India's ONGC operates multiple jack-ups for Mumbai High field (19.07°N 71.45°E) maintenance. The largest jack-up rig is Maersk Resolve (Maersk Drilling) at approximately 95m leg length.

The ships that build offshore wind farms and lay submarine cables
Offshore wind construction
WTIV — Wind Turbine Installation Vessel
A WTIV is a purpose-built jack-up vessel with a heavy-lift crane that installs offshore wind turbine components — monopile foundations, transition pieces, tower sections, nacelles, and rotor blades — at sea. They jack up their legs onto the seabed for stability during installation. The largest modern WTIVs (Heerema's Thialf, Jan De Nul's Les Alizés) can lift components of 5,000+ tonnes. Each turbine installation takes approximately 2–4 days. Installing 165 turbines for Hornsea Two (53.9°N 1.6°E) required multiple WTIV seasons over several years. WTIV bottleneck: only approximately 15–20 capable heavy-lift WTIVs exist globally — their availability is a constraint on how fast offshore wind can be built. The USA had no suitable WTIV until Dominion Energy's Charybdis (commissioned 2024) — the first Jones Act-compliant WTIV for the US market.

Power grid · Submarine cables
Cable Laying Ship
Cable laying ships lay high-voltage submarine power cables and telecommunications cables on the seabed. For offshore wind, they install export cables from the offshore substation to the onshore grid connection — typically 132–400 kV AC cables. For intercountry power grids, they lay HVDC cables — example: NordLink (623 km submarine HVDC cable between Norway and Germany, ±525 kV, 1,400 MW, installed 2020, laid by the Nexans Aurora and Jan De Nul cables vessels). The cable is stored on massive circular turntables (cable tanks) below deck, fed out over the stern as the ship moves. A typical 600 km HVDC cable installation takes 3–6 months. The global cable laying fleet is approximately 40–50 specialist vessels — also a capacity constraint on grid interconnection speed.

Heerema Sleipnir — World's Largest Crane Vessel
Heerema Marine Contractors' Sleipnir (launched , GPS when active: typically North Sea or Gulf of Mexico operations) is a semi-submersible crane vessel with two cranes capable of combined lifting of 220,000 tonnes — making it the world's largest crane vessel by lifting capacity. It installs jacket foundations for oil platforms, large offshore substation structures (5,000–10,000 tonnes), and performs heavy decommissioning lifts. Semi-submersible design means it lowers its pontoons below the waterline for exceptional stability during precision lifts. It runs on liquefied natural gas (LNG) propulsion — the largest vessel in the world to do so. Day rate approximately $1–2 million/day. Its sister vessel, Thialf, lifts up to 14,200 tonnes with two cranes. Named after Sleipnir — the eight-legged horse of Norse mythology.

Major pipeline systems — GPS located
The world's most important energy pipelines
Pipelines are the most economical way to transport large volumes of oil and gas overland. They operate 24 hours a day, are largely invisible, and form the invisible backbone of every energy system. The major cross-border pipelines are geopolitically significant because they create energy dependencies between nations.
| Pipeline | Route (with GPS endpoints) | Length | Capacity | Key facts |
|---|---|---|---|---|
| Druzhba Pipeline | Samara Russia (53.20°N 50.15°E) → Poland/Germany/Hungary/Slovakia/Czech Republic | ~4,000 km | ~1.2 M bbl/day | World's longest oil pipeline. Built 1964–1965. Named "Druzhba" (Friendship). Carries Russian Urals crude to Central Europe. Split at Mozyr Belarus into northern (Germany/Poland) and southern (Hungary/Slovakia/Czech) branches. Became geopolitically weaponised after 2022 Ukraine invasion — Western sanctions limited Russian oil exports but pipeline oil continued under partial exemptions for landlocked countries. |
| Trans-Alaska Pipeline (TAPS) | Prudhoe Bay (70.13°N 148.52°W) → Valdez terminal (61.11°N 146.35°W) | 1,287 km | 2.1 M bbl/day (peak) · ~500,000 now | Completed . Cost $8 billion. Carries North Slope crude across Arctic wilderness and three mountain ranges. Elevated above permafrost on heat dissipation supports to prevent permafrost melt. Tankers load at Valdez and transport oil to refineries on US West Coast. Flow has declined 75% from peak as Prudhoe Bay field depletes. |
| Baku-Tbilisi-Ceyhan (BTC) | Sangachal (40.16°N 49.65°E) → Ceyhan (36.65°N 35.77°E) via Tbilisi | 1,768 km | 1.2 M bbl/day | Commissioned . Built to give Azerbaijan and Kazakhstan export route bypassing Russia and Iran. Operated by bp. Crosses Azerbaijan, Georgia, Turkey. The BP/SOCAR/Chevron/Statoil consortium project was the largest pipeline construction project of its era — cost $3.9 billion. Carries Caspian light crude (33–40° API) to Ceyhan on Turkey's Mediterranean coast for tanker loading. |
| East Siberia-Pacific Ocean Pipeline (ESPO) | Taishet (55.93°N 98.00°E) → Kozmino Bay (42.76°N 133.08°E) and China spur | 4,188 km (+ 1,000 km China spur) | 1.6 M bbl/day | Russia's largest-ever infrastructure project. Completed (full). Carries East Siberian crude eastward to Pacific Ocean terminal (for tanker loading to Japan/Korea) and southward via Skovorodino (53.98°N 123.93°E) into China to Daqing refinery (46.60°N 125.01°E). Became critically important after Western sanctions as Russia pivoted exports to Asia post-. Crosses 8 time zones, 3,000 rivers and streams, and seismically active terrain. |
| Nord Stream 1 (destroyed) | Vyborg Russia (60.71°N 28.71°E) → Lubmin Germany (54.14°N 13.65°E) | 1,224 km | 55 bcm/year | Two parallel pipelines along the Baltic Sea floor. Operated by Nord Stream AG (Gazprom-majority). Commissioned . Provided Russia's main gas export route to Germany, bypassing Ukraine and Poland. Sabotaged in by underwater explosions near Bornholm island (55.20°N 15.00°E, Denmark's EEZ). Investigations by Germany, Sweden, and Denmark were inconclusive. Effectively destroyed and not repaired. Estimated damage: $20 billion infrastructure loss. |
| Saudi Petroline (East-West) | Abqaiq (25.93°N 49.67°E) → Yanbu (24.09°N 38.07°E) | 1,200 km | 5 M bbl/day | Saudi Aramco's Hormuz bypass pipeline. Provides the main alternative route if Hormuz is blocked. Carries crude across Saudi Arabia from the Eastern Province to the Red Sea coast for tanker loading at Yanbu. Capacity was doubled in the 2000s to 5 million bbl/day specifically as a Hormuz backup. However, even at full capacity this covers only ~25% of Hormuz oil throughput. |
| India GAIL HVJ Pipeline | Hazira (21.07°N 72.64°E) → Vijaipur (24.68°N 77.00°E) → Jagdishpur (26.40°N 82.00°E) | ~2,700 km (HVJ + extensions) | ~33 MMSCMD gas | India's largest natural gas pipeline. Hazira-Vijaipur-Jagdishpur (HVJ) was the first major gas pipeline in India, built in stages from 1987. Carries gas from Hazira LNG terminal and Gujarat fields to fertiliser plants and power stations in Uttar Pradesh, Rajasthan, and Madhya Pradesh. GAIL (Gas Authority of India Limited) is the majority owner and operator. India's total gas pipeline network: approximately 23,000 km operated by GAIL, GSPCL, and others. |

Land transport of energy
Trains, trucks, and turbine blade transport on land
Coal unit trains
The USA's Powder River Basin (44°N 106°W) — the world's largest coal-producing region at approximately 300 million tonnes per year — relies almost entirely on unit trains: dedicated 130–150 car coal trains running continuously from mine to power station. A single unit train carries approximately 12,000–15,000 tonnes of coal. Burlington Northern Santa Fe (BNSF) and Union Pacific together operate approximately 1,200 coal unit train runs per week out of the Powder River Basin. In India, Coal India's entire 773 MT/year production is transported by dedicated freight corridor (DFC) trains, of which the Eastern DFC (Ludhiana to Dankuni) was built specifically for coal haulage.
Wind turbine blade transport
Modern onshore wind turbine blades are 60–80 metres long. Transporting them by road is a major logistics challenge. Special blade transport trailers are used — some with steerable rear axles that allow the blade to tilt or rotate to navigate curves. Blade transport requires: route pre-surveys (identifying bridges, overhead cables, roundabouts too tight), police escorts, nighttime-only transport on major roads, temporary infrastructure removal. In some cases, blades must be manufactured near the wind farm site because road transport is impossible. Vestas has developed a "split blade" design (jointed at 50m) specifically to solve this problem. In offshore wind, blades can be transported by vessel without such restrictions.
Nuclear fuel transport
Nuclear fuel transport is strictly regulated and uses specially designed casks. Uranium hexafluoride (UF₆) cylinders for enrichment are transported by specialised road/rail vehicles. Spent nuclear fuel uses Type B flasks — massive steel and lead containers tested to survive crashes at 48 km/h, 1,000°C fires, and immersion in water. In the UK, BNFL's "CASTOR" flasks have been transported by rail for decades without incident. India's nuclear fuel cycle uses a combination of rail transport (between Talcher and enrichment plants) and road for final delivery. All nuclear transport is subject to IAEA regulations under its Transport Safety Standards (TS-R-1).
LNG road tanker — last-mile gas delivery
In India and across the developing world, many industrial consumers and city gas distribution networks cannot be connected to gas pipelines due to infrastructure gaps. LNG road tankers fill this gap: cryogenic tanker trucks carrying 20,000–40,000 litres of LNG at −162°C. They collect LNG from import terminals or satellite liquefaction plants and deliver it to industrial consumers (ceramic plants, textiles mills) or to regasification pods that feed city gas networks. India's GAIL and IOML operate growing LNG road tanker networks, particularly in Gujarat, Rajasthan, and Maharashtra where industrial demand outstrips pipeline supply. This "virtual pipeline" concept extends gas access without fixed infrastructure.

Questions about energy transport
How much does it cost to ship oil from Saudi Arabia to India?
The cost varies significantly with oil market conditions and ship availability. Using a VLCC from Ras Tanura (26.65°N 50.16°E, Saudi Arabia) to Vadinar/Jamnagar (22.47°N 69.87°E, India) — approximately 1,800 nautical miles — typical costs as of are approximately $1.00–1.50 per barrel for VLCC freight, or approximately $2 million–$3 million total for a full VLCC cargo (approximately 2 million barrels). This adds approximately $1–1.50/bbl to the landed cost of crude. At $80/bbl crude price, freight is approximately 1.5–2% of cargo value. In 2022 during the tight tanker market (post-Russia sanctions), VLCC rates spiked to $5–8/bbl briefly. Freight rates are quoted in Worldscale (WS) units — WS 100 is the notional base rate calculated by the Worldscale Association. Source: Worldscale Association · Clarkson Research shipping data.

How is LNG kept cold for weeks at sea?
LNG must stay at approximately −162°C throughout its sea voyage, which can last 2–4 weeks. This is achieved through insulation, not active refrigeration. Modern GTT membrane tanks have approximately 500 mm of polyurethane foam insulation between the −162°C cargo and the ambient temperature outside. Despite this, approximately 0.10–0.15% of the cargo "boils off" each day (the Boil-Off Gas Rate, or BOR). Modern ships use this boil-off gas as fuel for the propulsion system (DFDE or MEGI engines), replacing conventional heavy fuel oil. This means the cargo itself powers the ship — with the added benefit that using boil-off reduces the cargo loss. Very modern carriers with MEGI (Mark III Efficient Gas Injection) engines recompress and reliquefy the excess boil-off, achieving BOR as low as 0.07%/day. A 20-day voyage at 0.10% BOR loses approximately 2% of cargo — the ship's tanks are typically slightly overfilled to account for this.

Why is the WTIV (wind turbine installation vessel) shortage a problem for the energy transition?
The global shortage of Wind Turbine Installation Vessels is a genuine physical constraint on how fast offshore wind can be built — and therefore a constraint on the energy transition timeline. As of , approximately 15–20 vessels globally are capable of installing the latest generation of large offshore turbines (12–15 MW class). Building a new WTIV takes 3–5 years and costs approximately $500 million–$1 billion. The IEA's NZE 2050 scenario requires approximately 350–400 GW/year of offshore wind additions by 2030 — implying installation of approximately 25,000–30,000 turbines per year, each requiring 2–4 days of WTIV time. This would require a WTIV fleet 5–10 times larger than today's. The bottleneck is particularly acute in the USA, which until 2024 had no Jones Act-compliant WTIV (Jones Act requires US-flagged, US-built, US-crewed vessels for US coastal work). Foreign vessels needed Presidential waivers. Dominion Energy's Charybdis (commissioned 2024) is the first Jones Act WTIV — but the USA needs many more.

What happened to the Druzhba pipeline after Russia invaded Ukraine?
The Druzhba pipeline (4,000 km, Russia to Central Europe, capacity ~1.2 million bbl/day) became a central piece of Europe's energy crisis after Russia's invasion of Ukraine in February 2022. The pipeline was not immediately subject to Western sanctions because several landlocked EU countries (Slovakia, Czech Republic, Hungary, Germany's eastern refineries) were entirely dependent on it with no short-term alternative. Germany pledged to stop using Russian oil by end-2022 but took time to secure alternatives. Hungary and Slovakia, more geographically constrained, negotiated exemptions from EU oil sanction deadlines. By end-2023, Germany and Poland had fully switched to alternative supplies (Saudi, US, Kazakh crude via reverse flow on northern Druzhba). Southern Druzhba to Hungary, Slovakia, and Czech Republic continued operating into 2025 as these countries had no viable pipeline alternative to Atlantic oil routes. The episode demonstrated how pipeline dependencies, built over decades, take years to unwind — physical geography trumps political intent in the short term.
