Updated: 11 hours ago
Key Takeaway
A Very Large Crude Carrier (VLCC) is typically classified in the 200,000–320,000 DWT range; actual dimensions and cargo capacity vary by vessel design.
VLCC freight rates, operating costs and newbuild prices change with route conditions, fuel prices, yard capacity and market timing; use dated sources for current figures.
Sanctions and shadow-fleet assessments are vessel- and transaction-specific; consult official designation lists and current maritime guidance.
Table of Content
A fully loaded VLCC carries approximately 2 million barrels of crude oil, worth over $150 million at current prices, across oceans that most people will never see. At 300,000 deadweight tonnes, a VLCC is longer than three football fields, as tall as a 20-storey building when viewed from the waterline, and capable of trnsporting more energy in a single voyage than some countries consume in a week.
This guide covers everything you need to know about the vessels that underpin global oil trade.
Quick Answer: What Is a VLCC?
A Very Large Crude Carrier (VLCC) is an oil tanker with a deadweight tonnage (DWT) of 200,000 to 320,000 tonnes. It carries approximately 2 million barrels of crude oil per voyage and operates primarily on long-haul routes from the Persian Gulf to Asia, Europe, and North America. VLCCs are the workhorses of global seaborne crude oil transportation, accounting for the largest share of long-haul crude shipments globally.
What Is a VLCC? Definition and Classification
VLCC stands for Very Large Crude Carrier, a specific size class within the tanker market, defined by deadweight tonnage (DWT): the total weight of cargo, fuel, ballast, provisions, and crew a vessel can carry. VLCCs sit just below the Ultra Large Crude Carrier (ULCC) class and above Suezmax tankers in the AFRA (Average Freight Rate Assessment) classification system originally established by Royal Dutch Shell in 1954 to standardize freight rate negotiations.
Tanker Size Classification: Where VLCCs Sit
Vessel Class | DWT Range | Barrel Capacity | Typical Use | Port Access |
General Purpose | 10,000-24,999 | Up to 345,000 | Coastal, small ports | Most ports |
Medium Range (MR) | 25,000-44,999 | Up to 335,000 | Product tankers | Most ports |
Large Range 2 (LR2) | 80,000-159,999 | Up to 1 million | Clean/dirty products | Most major ports |
Suezmax | 120,000-200,000 | Up to 1 million | Suez Canal routes | Suez Canal (laden) |
VLCC | 200,000-320,000 | Up to 2.2 million | Long-haul crude | Deepwater terminals, SPMs |
ULCC | 320,000+ | Up to 4 million | Very limited routes | LOOP (US), Ras Tanura |
Why the VLCC Class Exists: Economies of Scale
The cost-per-barrel of transporting crude oil drops significantly as vessel size increases. A VLCC carrying 2 million barrels on the Persian Gulf-to-Japan route (TD3C) achieves a cost per barrel approximately 40-50% lower than the same volume carried by two Suezmax vessels. This economy of scale drives VLCC dominance on long-haul routes, the greater the distance, the larger the advantage.
VLCC Size, Dimensions, and Capacity
The physical scale of a VLCC is difficult to comprehend from specifications alone. The numbers below translate into real-world terms.
Tanker class | Typical deadweight tonnage (DWT) | Indicative dimensions | Cargo capacity | Newbuild cost |
Suezmax | About 120,000–200,000 DWT | Smaller than a VLCC; dimensions vary by design | Roughly 1 million barrels, depending on cargo and vessel | No current figure stated; obtain a dated yard or market source |
VLCC | About 200,000–320,000 DWT | Often around 330–340 m long and about 60 m beam; individual designs vary | Around 2 million barrels; some designs can carry more | The frequently quoted US$110–130 million range needs a dated, attributable market source before publication |
ULCC | Above about 320,000 DWT | Larger than a VLCC; limited terminal and route access | Up to around 4 million barrels for some designs | No current figure stated; obtain a dated yard or market source |
Comparison note: These are indicative class-level figures, not specifications or purchase prices for a particular vessel. The U.S. Army Corps of Engineers’ 2006 engineering manual illustrates a large tanker design with a 362 m overall length, 69.5 m beam and approximately 22.6 m full-load draft; actual VLCC particulars vary by design.
Specification | Typical Value | Real-World Equivalent |
Overall Length | 330-340 metres | Three football fields end-to-end |
Beam (Width) | ~60 metres | Wider than a six-lane motorway |
Loaded Draft | ~20 metres | Seven storeys below the waterline |
Ballast Draft | ~11 metres | Four storeys below the waterline |
Cargo Tanks | 15-17 tanks | Each tank holds ~120,000 barrels |
Engine Output | 25,000-30,000 HP | Equivalent to ~30 large diesel locomotives |
Service Speed | 14-15 knots loaded; 16+ knots ballast | ~26-28 km/h; slower than a cyclist on land |
Fuel Consumption | 70-90 tonnes/day at sea speed | ~$35,000-$50,000/day in bunker costs |
Bunker cost varies with fuel grade, price, consumption and route; do not use an undated daily dollar estimate.
VLCC vs ULCC: Why Ultra Large Carriers Are Rare
ULCCs exceed 320,000 DWT and can carry up to 4 million barrels, but their size creates severe operational constraints. A laden ULCC cannot transit the Strait of Malacca (maximum draft 25m limits VLCC transit to moderately loaded conditions), cannot use the Suez Canal when laden, and can only discharge at a handful of global deepwater terminals. The Louisiana Offshore Oil Port (LOOP) in the United States is the only US terminal capable of handling fully laden ULCCs. Most oil majors prefer the VLCC class for its near-universal deep water terminal access.
How a VLCC Works: Cargo Operations Step by Step
The cargo cycle of a VLCC involves far more than simply filling and emptying tanks. A single voyage from pre-arrival to next fixture involves 10 distinct operational phases, each governed by specific regulations, commercial obligations, and safety protocols.
Step 1 — Pre-arrival: The Master notifies the port authority, submits a pre-arrival notice, tests cargo pumps, and confirms the inert gas system is operational. Tank ullages are checked.
Step 2 — Mooring or SPM connection: The VLCC moors alongside a jetty or connects to a Single Point Mooring (SPM) buoy offshore. If port water depth is insufficient for the loaded draft, anchorage offshore is required and a lightering operation may follow.
Step 3 — Pre-loading survey: An independent cargo inspector measures empty tank ullages using UTI (Ullage, Temperature, Interface) gauges. These measurements establish the vessel's receiving capacity.
Step 4 — Line-up and manifold connection: Cargo hoses connect the vessel's manifold to the shore loading arm. The shore terminal confirms tank lineup before flow begins.
Step 5 — Inert gas purge: The inert gas system is confirmed active. Oxygen content in the cargo tanks must be below 8% before loading begins to prevent explosive vapour accumulation.
Step 6 — Loading: Crude oil is pumped aboard at typically 10,000-20,000 cubic metres per hour. The vessel's draft increases from approximately 11 metres to 20 metres over 24-36 hours.
Step 7 — On-hire survey and Bill of Lading: Independent measurements confirm loaded quantities. The Bill of Lading is signed, officially transferring cargo ownership to the receiver. The vessel is now on-hire under the charterparty.
Step 8 — Ocean voyage: Cross-ocean transit of 25-45 days depending on route. The crew maintains watch schedules, monitors cargo tank pressures, and handles routine maintenance.
Step 9 — Discharge: At the discharge terminal, cargo pumps transfer oil ashore over 24-36 hours. An off-hire survey confirms quantities delivered.
Step 10 — Tank cleaning and next fixture: Tanks are crude-washed (COW) using the retained cargo crude itself. The vessel takes on seawater ballast for stability and either proceeds directly to the next loading port or waits for a new charterparty fixture.
What Is a Ship-to-Ship (STS) Transfer?
An STS transfer involves pumping cargo between two vessels moored alongside each other at sea, without using a port terminal. Legitimate uses include: lightering (transferring cargo to a smaller vessel to reduce draft before entering a shallow port), emergency cargo transfer after a vessel incident, and commercial blending operations. STS transfers have also become central to the shadow fleet's cargo origin-obscuring operations, discussed in Section 11.
VLCC Trade Routes and Global Chokepoints
VLCCs operate on a defined set of long-haul routes. Freight rates are quoted on the Baltic Exchange using specific route codes against the Worldscale benchmark. The most important VLCC routes are:
Code | Route | Distance | Key Crude Grade | Typical Duration |
TD3C | Persian Gulf to Japan (Chiba) — global VLCC benchmark | ~6,500 nm | Arab Light, Murban | ~25 days |
TD2 | Persian Gulf to Singapore | ~3,800 nm | Arab Light, Arab Heavy | ~14 days |
TD15 | West Africa to China | ~11,000 nm | Bonny Light, Girassol | ~35 days |
TD1 | Middle East Gulf to US Gulf (LOOP) | ~11,500 nm | Arab Heavy | ~42 days |
TD20 | West Africa to European Continent | ~5,800 nm | West African grades | ~20 days |
The Five Chokepoints Every VLCC Must Navigate
Strait of Hormuz: Approximately 20% of global oil passes through this 33-kilometre-wide strait between Iran and Oman. Any disruption, military, political, or navigational, immediately affects VLCC freight rates globally. Every Persian Gulf-loading VLCC transits Hormuz on every laden voyage.
Strait of Malacca: At 25 metres maximum depth at its shallowest point, the Malacca Strait limits fully laden VLCC transit. Most VLCCs transit Malacca at 90-95% of full load, adjusting cargo levels to maintain clearance. A fully laden VLCC with a 20-metre draft must either reduce cargo or transit via the Lombok Strait (adding ~2-3 days to the voyage).
Bab-el-Mandeb: The 29-kilometre strait between Yemen and Djibouti connects the Red Sea to the Gulf of Aden. Houthi drone and missile attacks on commercial shipping from late 2023 onward forced most VLCC operators to reroute around the Cape of Good Hope, adding approximately 3,500 nautical miles and 10-14 days to Europe-bound voyages and significantly increasing tonne-miles.
Suez Canal: A laden VLCC is too wide and too deep for the Suez Canal. VLCCs transiting between the Persian Gulf and Europe route around the Cape of Good Hope unless travelling in ballast (unladen). The Cape routing adds approximately 3,000-4,000 nautical miles compared to the Suez route.
Cape of Good Hope: The alternative to Suez for fully laden VLCCs. Weather conditions in the Southern Ocean can be severe, particularly in the winter months (June-August in the Southern Hemisphere). Additional days at sea increase voyage costs but also increase tonne-mile supply, which supports freight rates.
VLCC Design: Double Hull, Inert Gas System, and Ballast Tanks
Why Double Hulls Are Mandatory
The 1989 Exxon Valdez disaster, which spilled 37,000 tonnes of crude oil into Prince William Sound, Alaska, accelerated international regulatory action on single-hull tanker design. MARPOL Regulation 13G required all new tankers ordered from 1993 onward to be double-hulled. A double hull consists of two layers of watertight hull separated by a void space of typically 2-3 metres. In a collision or grounding, the outer hull may breach while the inner hull, which contains the cargo tanks, remains intact. The last single-hull VLCCs were phased out of international trade by 2010 under MARPOL Annex I.
How the Inert Gas System Works
Crude oil vapour in an empty or partially filled cargo tank creates an explosive atmosphere when mixed with oxygen above the lower explosive limit (LEL). The inert gas system (IGS) addresses this directly by filling the cargo tank atmosphere with oxygen-depleted gas, typically flue gas from the ship's boilers or a dedicated inert gas generator, to maintain oxygen content below 8% by volume. At below 8% oxygen, ignition of hydrocarbon vapour becomes effectively impossible. The IGS is one of the most critical safety systems on a VLCC: its failure during cargo operations triggers an immediate operational stop. Inert gas system requirements are mandated by SOLAS Chapter II-2 and MARPOL Annex I for all tankers above 20,000 DWT.
Ballast Water Management
A VLCC in ballast condition (no cargo) takes on up to 70,000 tonnes of seawater as ballast to maintain stability, propeller immersion, and structural integrity on the return voyage. This ballast water, drawn from the loading port, contains local marine organisms, bacteria, plankton, invertebrate larvae, that are discharged at the discharge port, potentially establishing invasive species in new ecosystems. The IMO Ballast Water Management Convention (in force 2017) requires VLCCs to treat ballast water before discharge, either through mid-ocean ballast exchange or through certified ballast water treatment systems (BWTS) installed on board. All VLCCs built after September 2019 must have a compliant BWTS; all existing vessels must have retrofitted one by their next drydock after September 2024.
VLCC Charter Rates and Freight Market Economics
VLCC freight rates are quoted on the Worldscale system, a standardized benchmark recalculated annually for each route. Worldscale 100 (WS100) represents the flat rate for a specified route and reference vessel; actual fixtures are quoted as a percentage of WS100. TD3C is a major VLCC benchmark route assessed by the Baltic Exchange. Rates are time-sensitive: for example, Reuters reported on 16 October 2026 that rates on the Gulf of Oman-to-China route had fallen to WS776 from WS841 the previous week. This is a dated market observation for a specific route, not a current universal VLCC rate.
What Moves VLCC Freight Rates
OPEC+ production decisions: More OPEC+ output means more crude to move and more VLCC demand. Production cuts reduce loadings, depress rates. The correlation between OPEC+ policy announcements and TD3C rate movements is immediate and significant.
Geopolitical disruptions: Routing changes caused by conflict or sanctions (Hormuz, Bab-el-Mandeb, Black Sea) add tonne-miles to voyages — vessels travel further to carry the same cargo — which tightens effective fleet supply and supports rates.
Seasonal refinery runs: Q4 and Q1 typically see peak crude demand as Northern Hemisphere heating oil season drives refinery throughput. VLCCs follow refinery pull, not just crude availability.
Newbuild deliveries vs. scrapping: Fleet supply growth from newbuild deliveries puts downward pressure on rates. Accelerated scrapping of aged tonnage tightens supply. The VLCC orderbook as a percentage of the existing fleet is a watched metric for medium-term rate forecasting.
Slow steaming: When rates are low, owners slow steam to reduce fuel costs. Slower vessels absorb more calendar days per voyage, effectively reducing fleet supply and providing some rate floor. The reverse effect, speeding up when rates spike, increases fleet supply and caps rate upside.
Spot vs Time Charter: How VLCC Owners Earn Revenue
A spot charter (voyage charter) fixes the vessel for a single voyage at the prevailing market rate. Spot fixtures dominate the VLCC market and are the mechanism through which TD3C rates are established. A time charter fixes the vessel for a defined period (typically 1-3 years for VLCCs) at a daily hire rate agreed upfront. Time charters transfer voyage cost risk (fuel, port costs) to the charterer. Major oil companies and national oil companies (Saudi Aramco via Bahri, BP, Chevron) tend to hold time-chartered VLCC fleets for supply security. Independent oil traders (Vitol, Gunvor, Trafigura) dominate the spot market.
VLCC Fleet: Who Owns and Operates Them
The global VLCC fleet numbers approximately 850-900 vessels as of 2026, operated by a mix of national shipping companies, listed tanker owners, and diversified shipping groups. Ownership is fragmented: no single owner controls more than 5-6% of the fleet.
Operator | Headquarters | VLCC Fleet Size (approx.) | Notable Feature |
Bahri (National Shipping Co. of Saudi Arabia) | Riyadh, Saudi Arabia | 40+ vessels | World's largest double-hull VLCC operator; exclusive partner for Saudi Aramco CIF crude sales |
COSCO Shipping Energy | Shanghai, China | 35+ vessels | Largest Asian VLCC operator; dominant on Middle East-China routes |
Euronav | Antwerp, Belgium (NYSE: CMBT post-merger) | 30+ vessels | Merged with Frontline in 2023; combined entity is one of the largest listed tanker fleets |
DHT Holdings | Hamilton, Bermuda (NYSE: DHT) | 25+ vessels | Pure-play VLCC operator; no diversification into other tanker classes |
Mitsui OSK Lines (MOL) | Tokyo, Japan | 20+ vessels | Operates under long-term Japanese oil company time charters; partner for green VLCC newbuilds |
VLCC Regulations: MARPOL, CII, and EEXI
MARPOL Annex I and Double-Hull Requirements
All VLCCs operating in international trade today are double-hulled following the MARPOL Annex I phase-out of single-hull tankers completed by 2010. The IOPP (International Oil Pollution Prevention) Certificate, valid for five years with annual surveys, is the primary Annex I compliance document carried by every VLCC. The Oil Record Book Part II (cargo operations) must be maintained and produced to port state control officers on request.
CII and EEXI: The 2023 Regulatory Shift
Two regulations that entered into force on 1 January 2023 under MARPOL Annex VI have fundamentally changed VLCC commercial planning. The Carbon Intensity Indicator (CII) rates each vessel A to E annually based on actual CO2 emissions per capacity-mile. A VLCC rated D for two consecutive years or E for one year must submit a corrective action plan to its flag state before its next voyage. In commercial practice, a D or E rating significantly impairs a vessel's charterability: major oil companies include CII performance requirements in charterparty clauses.
The Energy Efficiency Existing Ship Index (EEXI) is a one-time technical baseline assessment. VLCCs failing to meet the required EEXI level must implement Engine Power Limitation (EPL/ShaPoLi), effectively capping the vessel's maximum speed. For older VLCCs with less efficient engines, the EEXI compliance cost combined with CII pressure has accelerated the economic case for early scrapping. Industry analysis by Clarksons Research estimated that up to 15% of the pre-2005 VLCC fleet faced meaningful EEXI compliance challenges at the 2023 entry into force date.
IMO 2030 and 2050 GHG Targets
The revised IMO GHG Strategy adopted at MEPC 80 in July 2023 targets 20-30% GHG reduction by 2030 vs. 2008 baseline and net-zero emissions by 2050. For VLCC owners, these targets drive the investment calculus for new VLCC orders: any vessel ordered today will still be trading in 2045, meaning dual-fuel capability or future fuel readiness is increasingly factored into newbuild specifications.
The Green Transition: Alternative Fuels for VLCCs
VLCCs are among the most energy-intensive commercial vessels in operation. At 70-90 tonnes of fuel per day at sea speed, the cost and emissions implications of any fuel transition are significant. Four alternative fuel pathways are currently being pursued by VLCC owners and operators.
Fuel | Commercial Status | GHG Reduction | Key Challenge | VLCC Adoption |
LNG | Commercial, now | ~20% (WTW) | Methane slip; LNG bunkering availability at major VLCC terminals | Qatar-chartered vessels; COSCO newbuilds |
Biofuel blends (B24/B30) | Commercial, now | 20-30% (blended) | Supply chain constraints; feedstock competition; cost premium | NYK Tenjun and several MOL vessels (B24 trials) |
Methanol (dual-fuel) | Newbuilds 2027-28 | ~15% grey; ~95% green methanol | Green methanol supply chain not yet at scale for VLCC volumes | NYK (two newbuilds on order) |
Ammonia (dual-fuel) | Pilot stage | Near-zero (green) | High toxicity (TLV 25 ppm); no bunkering infrastructure; crew training | No VLCC yet; pilot vessels in smaller classes |
Slow Steaming: The Cheapest CII Improvement Tool
Reducing a VLCC's speed from 15 knots to 12 knots can materially reduce fuel consumption, but the saving depends on hull condition, loading, weather, engine and operating profile. Do not present a fixed percentage without a dated technical or operator source. Slow steaming has become the primary short-term tool for owners managing CII performance. The trade-off is voyage duration: a TD3C voyage (Persian Gulf to Japan) that takes 25 days at 15 knots takes 31-32 days at 12 knots. Slower vessels occupy more calendar days per voyage, reducing the number of voyages per year and effectively tightening fleet supply, which paradoxically supports freight rates in a market where most vessels are slow steaming simultaneously.
Life Onboard a VLCC: Crew, Voyages, and Daily Reality
This section has no equivalent on any competitor page. A VLCC is not just a vessel, it is a floating workplace for 25-30 seafarers, typically away from home for 4-9 months at a stretch.
Who Sails on a VLCC
A typical VLCC complement consists of: Master, Chief Officer (Cargo Officer), 2nd Officer (Navigation Officer), 3rd Officer, Chief Engineer, 2nd Engineer, 3rd Engineer, 4th Engineer, Electro-Technical Officer (ETO), Bosun, Pump Man, 4-6 Able Seamen, 2-3 Ordinary Seamen, Pumpman Cadet, Engine Cadet, Cook, and Steward. Dominant crew nationalities on internationally operated VLCCs are Filipino, Indian, and Ukrainian officers and ratings, reflecting the deep integration of these maritime labour markets into global tanker operations.
Indicative Monthly Salary Ranges
Role | Monthly Salary Range (USD) | Typical Contract Length |
Master (Captain) | $10,000 - $14,000 | 3-5 months |
Chief Engineer | $9,000 - $13,000 | 3-5 months |
Chief Officer | $6,000 - $8,500 | 4-6 months |
2nd/3rd Officer | $3,500 - $5,500 | 4-6 months |
Electro-Technical Officer | $4,000 - $5,500 | 4-6 months |
Able Seaman (AB) | $1,500 - $2,500 | 6-9 months |
Note: Salary ranges vary significantly by flag state, manning agency, and employment contract terms. Figures represent indicative market ranges for internationally crewed vessels as of 2026.
A Typical TD3C Voyage: 45 Days in the Life
A typical VLCC voyage from Ras Tanura (Saudi Arabia) to Chiba (Japan) begins with cargo loading over 24-36 hours alongside a jetty or SPM. The vessel then transits the Persian Gulf, passes through the Strait of Hormuz, crosses the Arabian Sea, transits the Strait of Malacca (at reduced load for draft clearance), and arrives at the Chiba anchorage off Tokyo Bay. Discharge takes 24-36 hours. Total laden passage: approximately 25 days.
Then ballast return: another 20-22 days back to the Gulf, or diversion to another loading region if a new fixture is secured mid-voyage. The crew operates on a 4-hours-on/8-hours-off watch system. Internet connectivity via satellite (VSAT) is now standard on most major operators' VLCCs, though bandwidth is limited. Recreational facilities typically include a gym, a small lounge, and a pool on newer vessels.
The VLCC Shadow Fleet and Sanctions Trade
The term “shadow fleet” is used in policy and maritime reporting for vessels and networks associated with sanctioned oil trades or other high-risk shipping practices. It is not a single, universally defined fleet, and a vessel should not be described as engaged in sanctions evasion without reliable, specific evidence. Official designation lists and dated enforcement notices are the appropriate sources for claims about named vessels or entities.
What Is the Shadow Fleet
The term can refer to vessels involved in sanctioned trade, opaque ownership or management arrangements, or practices such as AIS manipulation. These indicators are not interchangeable, and no one indicator alone proves a sanctions violation. A global fleet estimate should be included only when the original report, publication date, vessel definition and methodology can be verified.
Government designation lists provide a different, more specific measure. On 23 July 2026, the Council of the European Union reported that more than 670 vessels had been listed under its Russia-related sanctions regime. This is a count of vessels designated under that regime, not an estimate of every vessel considered part of the global shadow fleet.
Reported risk indicators include opaque ownership or management structures, inconsistent vessel or cargo documentation, AIS signal manipulation, ship-to-ship (STS) transfers that warrant additional scrutiny, and uncertainty about insurance arrangements. None of these indicators alone establishes that a vessel has violated sanctions. Assessment should be based on verifiable vessel records, applicable sanctions lists and the circumstances of the specific voyage.
STS Transfers as Cargo Origin Obscuring
Ship-to-ship (STS) transfers are used for legitimate maritime purposes, including lightering and cargo transfer, and are not inherently unlawful. Regulators have identified specific vessels and networks that used irregular or high-risk shipping practices to conceal the origin or movement of sanctioned commodities. For example, the Council of the EU reported on 15 December 2025 that certain listed entities controlled vessels transporting Russian-origin crude or petroleum products while concealing the actual origin of oil.
An STS transfer at a particular location, including the Strait of Gibraltar or the Gulf of Oman, is not, by itself, evidence of sanctions evasion. Assessment should consider vessel identities, ownership and management records, AIS history, cargo documents, counterparties and the sanctions rules applicable to the transaction.
Regulatory Response and Market Impact
Sanctions authorities continue to designate vessels, owners, managers and other entities connected with prohibited or high-risk trade. On 8 October 2026, the US Department of the Treasury announced action against vessels and networks it said were involved in transporting Iranian petroleum and related products. On 21 October 2026, it announced further measures targeting shipping agents, corporate-service providers and cargo vessels connected with Iranian trade. These are specific enforcement actions and should not be interpreted as evidence that every vessel described as part of a shadow fleet is sanctioned.
Sanctions and related restrictions can affect whether a vessel may lawfully be used by a particular charterer, access particular ports or services, or participate in a transaction involving restricted persons. International Group P&I clubs maintain sanctions-compliance procedures, and cover may be excluded or prejudiced where a voyage or activity breaches applicable sanctions. However, vessels described as part of the “shadow fleet” are not automatically all subject to the same insurance outcome: Lloyd’s List has reported that some tankers associated with this category have held International Group cover for trades complying with applicable restrictions. Insurance status should therefore be assessed against the vessel, voyage, counterparties, policy terms and relevant law.
The market impact is also route- and time-dependent. Sanctions may reduce the number of vessels available to compliant charterers, while changes in trade flows and voyage distances can alter vessel demand and tonne-mile requirements. The net effect on VLCC freight rates cannot be assumed to be uniformly positive or negative across routes and periods; it requires dated freight-market and fleet-utilization evidence.
For shipowners, charterers and maritime analysts, the practical implication is to treat sanctions exposure, ownership transparency, vessel history, cargo provenance and insurance documentation as separate due-diligence questions. A vessel’s past STS activity or other risk indicator warrants further review, but should not be presented as proof of misconduct without reliable evidence. This section is intended as general industry information, not legal advice or a determination that a particular vessel or transaction complies with applicable sanctions.
VLCC Scrapping and End-of-Life
When Does a VLCC Get Scrapped
The economic scrapping decision is made when the sum of ongoing operating expenses (crew, maintenance, insurance, class) plus the projected drydock cost at the next special survey exceeds the vessel's discounted future earnings capacity. For VLCCs, this point typically arrives at 20-25 years of age, earlier for vessels with poor CII profiles or pending regulatory capital expenditure.
At scrap, the vessel is valued in LDT (Light Displacement Tonnes), the weight of the vessel itself without cargo or fuel. A 300,000 DWT VLCC may have a light displacement of roughly 42,000–46,000 LDT, depending on its design. Recycling value depends on the vessel’s LDT, condition, location, and the prevailing scrap price; any dollar-per-LDT or total-value estimate should be accompanied by a dated market source. No undated recycling valuation is stated here.
Where VLCCs Go to Die: The Ship Recycling Industry
Approximately 60% of global ship recycling by tonnage takes place at Alang, Gujarat, India. Gadani (Pakistan) and Chittagong (Bangladesh) account for most of the remainder. The Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships (entered into force 2025) requires vessels to carry a Hazardous Materials Inventory and to be recycled only at approved yards meeting specific environmental and worker safety standards. The EU Ship Recycling Regulation restricts EU-flagged vessels to recycling at EU-approved facilities, a list that includes only selected yards in Turkey, the UK, and a small number of other countries, currently excluding most Alang and Gadani yards. For VLCC owners managing end-of-life decisions, the flag state under which the vessel ends its commercial life affects where it can legally be scrapped.
Frequently Asked Questions About VLCC Ships
What does VLCC stand for?
Very Large Crude Carrier. A VLCC is an oil tanker in the 200,000-320,000 DWT size range, primarily used to transport crude oil on long-haul international routes from the Persian Gulf to Asia, Europe, and North America.
How many barrels of oil does a VLCC carry?
Approximately 2 million barrels per voyage, depending on vessel and cargo. The cargo’s monetary value changes with the crude grade and market price, so no fixed dollar valuation is given here.
How long does a VLCC voyage take?
A Persian Gulf to Japan (TD3C) voyage takes approximately 25 days laden and 20-22 days in ballast. Persian Gulf to US Gulf (TD1, via Cape of Good Hope) takes 40-45 days laden. Weather, port waiting times, and speed selection affect actual voyage duration.
What is TD3C?
TD3C is the benchmark VLCC freight route: Persian Gulf to Japan (Chiba), quoted in Worldscale points on the Baltic Exchange. It is the primary reference rate for the global VLCC spot market.
How fast does a VLCC travel?
A VLCC travels at 14-15 knots when fully loaded. At slow steaming speed (12 knots), fuel consumption drops by approximately 35% and CII score improves. Maximum design speed is typically 16-17 knots in ballast condition.
What is the CII regulation and how does it affect VLCCs?
The Carbon Intensity Indicator (CII), in force since January 2023, rates vessels A to E annually based on CO2 per capacity-mile. A VLCC rated D for two consecutive years or E for one year must submit a corrective action plan to its flag state. Poor CII ratings restrict charterability with major oil companies.
Why can't VLCCs enter most ports?
A fully loaded VLCC has a draft of approximately 20 metres, exceeding the water depth of most commercial ports. VLCCs use offshore Single Point Mooring (SPM) buoys, lightering operations, or the handful of deepwater dedicated crude terminals globally (Ras Tanura, Kharg Island, Fujairah, Ningbo, Chiba).
What is a shadow fleet VLCC?
“Shadow fleet” is a broad, non-uniform term used for vessels associated with sanctioned trades or high-risk shipping practices. A vessel’s status and insurance position must be checked against current official lists, the voyage and applicable policy terms; the label alone does not prove sanctions evasion.
How much does it cost to build a VLCC?
VLCC newbuild prices vary by yard, delivery slot, specification, fuel system and market conditions. The often-quoted US$110–130 million range for conventional-fuel vessels, and a 15–25% premium for dual-fuel LNG designs, should be published only with a dated Clarksons Research or shipyard source that confirms those figures. Without that source, treat the figures as unverified and do not present them as current prices.
When is a VLCC scrapped?
Typically at 20-25 years of age when OPEX plus drydock costs exceed discounted future earnings. CII and EEXI compliance costs are accelerating the scrapping of older, less efficient vessels. A VLCC’s recycling value depends on its light displacement tonnage, condition and prevailing scrap prices; use a dated market source for any dollar estimate.

LDT | Light Displacement Tonnage. The weight of the empty vessel without cargo, fuel, or provisions. Used to calculate scrap value: a 300,000 DWT VLCC has an LDT of approximately 42,000-46,000 tonnes. |
Lightering | Transferring cargo from a VLCC to a smaller vessel offshore to reduce the VLCC's draft enough to enter a shallow terminal. |
Shadow Fleet | Vessels, often older and inadequately insured, used to transport sanctioned crude oil from Russia, Iran, and Venezuela outside the Western financial and insurance system. |
Slow Steaming | Operating at reduced speed to cut fuel consumption and improve CII rating. Reducing from 15 knots to 12 knots cuts fuel consumption by approximately 35%. |
SPM | Single Point Mooring. An offshore mooring buoy system allowing VLCCs to load or discharge where port access is impossible due to draft constraints. |
STS Transfer | Ship-to-Ship Transfer. The transfer of cargo between two vessels moored alongside each other at sea. Used legitimately for lightering; used in shadow fleet operations to obscure cargo origin. |
TD3C | The global VLCC benchmark freight route: Persian Gulf to Japan (Chiba). Quoted daily on the Baltic Exchange in Worldscale points. |
Time Charter (TC) | A charter arrangement where the vessel and crew are provided for a fixed period. The charterer pays daily hire and covers voyage costs including fuel and port charges. |
ULCC | Ultra Large Crude Carrier. Tankers exceeding 320,000 DWT with very limited port access. Largely phased out of mainstream crude trade due to operational constraints. |
Worldscale (WS) | A standardized tanker freight rate system. WS100 is the theoretical flat rate for a given route recalculated annually. Actual rates are quoted as a percentage of WS100. |
