What a shipping company truly needs is fleet capacity—not ship ownership#
Cargo owners will not automatically pay higher freight simply because a vessel is registered to the carrier. Customers buy a transport commitment that can be fulfilled.
A container carrier's core purpose is to move containers from origin to destination, maintain scheduled services, control costs, and earn a reasonable return on each trade. What cargo owners actually care about is whether:
- space is available when cargo needs to move;
- schedules are reliable and transshipment connections work;
- cargo arrives safely;
- disruptions are handled effectively;
- the overall service price is reasonable.
A container carrier's product is therefore not an individual ship, but a scheduled transport service formed by vessels, containers, terminals, transshipment hubs, feeder networks, inland transport, and information systems.
If a chartered-in vessel meets route, schedule, performance, and technical requirements, it can be deployed in the carrier's service network just like an owned vessel. That is why the prominent brand painted on a ship's hull does not necessarily identify its legal owner.
First distinguish who owns, manages, and commercially employs the ship#
The first step in understanding chartering is to separate legal ownership, technical management, and commercial employment.
Shipowner
Holds legal title and bears vessel-price, residual-value, and disposal risks. The owner may be a carrier, an independent shipowner, or an asset-owning company in a financing structure.
Technical manager
Responsible for crewing, maintenance, spare parts, insurance, class, dry-docking, and the vessel's basic seaworthiness. The shipowner may manage these functions directly or appoint a ship-management company.
Commercial operator
Decides which service employs the vessel, what cargo it carries, and how capacity and port calls are allocated. The hull branding usually reflects this role.
All three roles may sit within one company or be divided among separate entities. Under a typical time charter, the shipowner retains ownership and technical management while the carrier obtains the right to direct the vessel's commercial employment.
“Operated fleet” generally means vessels commercially operated by the carrier; it does not mean they are all carrier-owned. “Owned fleet” refers to vessels owned legally or on the group's consolidated reporting basis.
Not all charters are the same#
Time charters, bareboat charters, voyage charters, and slot arrangements allocate control and responsibility in fundamentally different ways.
Owned vessel
The carrier owns the vessel asset, manages or outsources crewing, maintenance, and regulatory compliance, and controls commercial deployment.
Time-chartered vessel
The shipowner normally provides the crew and technical management. The chartering carrier pays daily hire and arranges routes, cargo, bunkers, and voyage operations.
Bareboat charter
The charterer takes possession and full control of the vessel and is generally responsible for crewing, maintenance, insurance, and operating expenditure, making the arrangement economically similar to ownership.[1]
Slot charter / vessel sharing agreement
A carrier does not obtain an entire vessel; it purchases or exchanges slots on a particular service, expanding its network with fewer assets.
In this article, “chartered-in vessel” primarily refers to the time-chartered vessel commonly used by container liner operators. Actual responsibilities are governed by the charter party and cannot be inferred from the label alone.
Why do shipping companies own vessels?#
The central value of ownership is not merely carrying an asset on the balance sheet, but having greater control over long-term fleet capacity, vessel specifications, and asset disposal.
Secure capacity for core services
A liner service requires multiple vessels calling at ports in a fixed rotation. Because owned vessels are not subject to charter expiry or redelivery, they reduce exposure to costly renewals in a tight charter market.
Potentially lower cost at sustained high utilization
Charter hire generally includes the shipowner's financing cost, depreciation, crew, maintenance, insurance, risk premium, and profit. If a carrier can keep a vessel fully employed over the long term, ownership may reduce average capacity cost.
Specify the vessel
For an owned newbuilding, the carrier can specify capacity, speed, main engine, fuel, reefer plugs, energy-saving equipment, shore power, and future retrofit allowances, while standardizing the fleet.
Retain residual value and asset options
An owned vessel can be sold, chartered out, mortgaged, sold and leased back, or ultimately recycled. The carrier captures asset appreciation when vessel values rise, but also bears losses when they fall.
Ownership can deliver a long-term cost advantage only when the purchase price, financing cost, utilization, maintenance capability, technical life, and residual value are all reasonable.
Why do shipping companies charter in vessels?#
Chartering provides fleet capacity without waiting for a newbuilding and leaves part of the asset and technical risk with a professional shipowner.
Add or supplement capacity quickly
New services, peak seasons, rerouting, port congestion, dry-dock relief, or alliance changes can suddenly require more tonnage. Chartering an available vessel is usually faster than ordering a newbuilding.
Reduce upfront capital needs
By paying daily hire for the right to use a vessel, a carrier can preserve cash for containers, terminals, warehousing, information systems, inland logistics, and working capital.
Reduce vessel-price and residual-value exposure
After redelivery, secondhand value, age-related discounts, recycling value, and technological obsolescence generally remain with the shipowner, allowing the carrier to select a newer vessel type.
Use a professional shipowner's management capability
Under a time charter, the shipowner normally handles crewing, maintenance, class, dry-docking, and insurance, allowing the carrier to focus resources on services, cargo, pricing, and customer service.
Chartering, however, transfers only part of the technical and asset risk. Off-hire provisions may not fully compensate for port omissions, missed transshipment connections, customer claims, or schedule disruption caused by vessel breakdowns.
Owned versus chartered-in vessels#
| Factor | Owned vessels | Chartered-in vessels |
|---|---|---|
| Upfront capital | High: purchase price, newbuilding installments, or financing required | Relatively lower, although deposits and guarantees may apply |
| Speed of access | Newbuildings have long lead times; secondhand vessels depend on market availability | Can enter service more quickly when suitable tonnage is available |
| Long-term cost | Potentially lower with high utilization and a reasonable purchase price | Hire includes the shipowner's costs, risk, and profit |
| Control of core capacity | Higher; not affected by charter expiry | Exposed to owner performance, charter duration, and the renewal market |
| Vessel specifications | Can be designed and standardized by the carrier | Usually accepts existing specifications |
| Technical management | Handled by the carrier or its technical manager | Normally handled by the shipowner under a time charter |
| Vessel price and residual value | Captures upside but bears declines and impairment | Normally borne by the shipowner |
| Technological obsolescence | The asset may become outdated before the end of its useful life | Can change vessels when the charter expires |
| Market contraction | Must sell, charter out, or idle the vessel; adjustment is slower | Can redeliver the vessel at charter expiry |
| Rising charter market | Ownership cost is relatively stable | Renewal or replacement tonnage may become much more expensive |
| Falling charter market | Cannot directly benefit from lower charter rates | Can renew or fix replacement tonnage at lower market rates when a short charter expires |
| Asset appreciation | Captured by the carrier | Not directly captured by the carrier |
Research shows that major container carriers use different combinations of vessel size, age, and charter duration, and that they adjusted their chartering policies differently during the COVID-19 disruption. This supports a basic observation: fleet structure is closely tied to a carrier's services, capital position, historical orderbook, and market position. No fixed ratio suits every carrier.[4]
The financial view goes beyond CapEx versus OpEx#
Buying a vessel generally creates an asset; chartering generally requires daily hire. What matters most, however, is the future fixed-payment burden, cash-flow resilience, and who bears each risk.
- CAPEXCapital Expenditure
- Expenditure to acquire, construct, or substantially improve a long-lived asset, such as buying a vessel or ordering a newbuilding. The expenditure is generally recognized as an asset first, then expensed over its useful life through depreciation or amortization.
- OPEXOperating Expenditure
- Costs incurred to maintain day-to-day operations, such as crew, maintenance, insurance, and general administration, generally expensed in the period incurred.
Reading note: CapEx and OpEx describe spending and accounting treatment. Whether a charter creates a right-of-use asset and lease liability still depends on the contract and IFRS 16.
Financial characteristics of an owned vessel
- Vessel asset, depreciation, and possible impairment;
- newbuilding installments, loan principal, and interest;
- cash outflows for crew, maintenance, insurance, and dry-docking;
- residual value from eventual sale or recycling.
Financial characteristics of a time-chartered vessel
- hire paid daily or periodically;
- hire generally remains payable in a weak market;
- a long-term charter may create a multi-year fixed commitment;
- the carrier generally has no residual interest in the vessel at charter expiry.
Why is chartering not necessarily pure OpEx?
IFRS 16 is the lease-accounting standard issued by the International Accounting Standards Board (IASB), effective from 1 January 2019. Its core principle is that a lessee generally recognizes both a right-of-use asset and a lease liability for leases longer than 12 months unless the underlying asset is of low value, presenting the right to use the asset and the obligation to make future lease payments.[9]
Under IFRS 16, a contract may contain a lease when it involves an identified vessel and the charterer has the right to obtain substantially all of the economic benefits from its use and the right to direct its use throughout the period of use. If the arrangement is a lease, the charterer may need to recognize a right-of-use asset and a lease liability. The shipowner's continued responsibility for operation and maintenance does not necessarily change that conclusion.[2]
Instead of asking only whether something is CapEx or OpEx, ask: how much unavoidable payment is due each year, and can the company still pay when freight rates fall or vessel utilization is weak?
What do shipping companies actually consider?#
A carrier does not permanently prefer ownership or chartering. It evaluates cargo volume, vessel prices, charter rates, financing, technology, and shipowner quality within one decision.
Cargo volume and service visibility
Mature, long-term core services that cannot be interrupted place more value on stable capacity. Seasonal demand, new markets, or short-term cargo place more value on the ability to adjust after charter expiry.
Relative vessel prices and charter rates
Shipping markets are highly cyclical. High vessel prices with low charter rates can lead to a very different decision from low vessel prices with high charter rates. The same carrier may change its approach from year to year.
Cash and financing capacity
Ownership consumes more upfront capital. Chartering preserves cash, but an expensive long-term charter can still become a heavy fixed-payment burden. An asset-light model is not free of leverage risk.
Vessel reliability and management capability
Owned vessels require capability in crewing, maintenance, spare parts, class, and dry-dock management. For chartered-in vessels, the carrier must assess the shipowner's technical and financial standing, PSC record, vessel performance, and contractual performance history.
Fuel, decarbonization, and retrofit risk
Ownership gives the carrier control over main-engine selection, dual-fuel systems, shore power, and retrofits. Chartering can reduce the risk of committing to the wrong technology, but differing investment incentives between shipowner and charterer may delay efficiency improvements.
Charter duration and exit terms
A one-year charter and a ten-year charter are different products. Flexibility depends on duration, extension options, purchase options, early-redelivery terms, and the charter-expiry profile—not on the word “charter” itself.
On decarbonization incentives, one container-shipping study found that, within its sample and model, the split incentives between shipowner and charterer created by chartering were associated with higher carbon emissions. This does not mean every charter performs worse; it shows that when the party benefiting from fuel savings differs from the party investing in equipment, responsibility and payback mechanisms for efficiency investment become especially important.[5]
The decision differs for 13,000–16,000 TEU and 20,000+ TEU vessels#
Vessel size affects service fit, port constraints, utilization difficulty, and redeployment options, and therefore changes the ownership-versus-chartering decision.
- Meaningful economies of scale;
- deployable across several east–west mainline trades;
- generally broader port coverage than ultra-large vessels;
- relatively easier to achieve adequate utilization and to redeploy across services;
- potentially a versatile long-haul workhorse for a major carrier.
- Can reduce unit cost at sea when highly utilized;
- more dependent on high-density mainline trades such as Asia–Europe;
- requires deep-water ports, large quay cranes, and sufficient yard capacity;
- increases peak pressure on transshipment, feeders, and landside logistics;
- harder to redeploy when services and ports are unsuitable.
The ITF/OECD notes that incremental cost savings diminish as vessel size increases, while some pressure shifts to ports, terminals, feeder services, and landside logistics. The economics of an ultra-large vessel must be supported by the entire service network.[3]
Therefore, whether a carrier owns or long-term charters a vessel above 20,000 TEU, a long commitment creates similar exposure to the vessel type's dependence on a small number of mainline trades.
Current public fleet structures of Evergreen, Yang Ming, and Wan Hai#
The three carriers show different ownership and chartering mixes, but their snapshot dates, consolidation bases, and pace of fleet change differ. The data is useful for understanding structures, not for a synchronized ranking.
Evergreen: predominantly owned, supplemented by charters
Evergreen builds long-term core capacity with a large owned fleet, yet its 77 chartered-in vessels still form a substantial supplementary fleet. This shows that even a large asset-based carrier uses charters to meet vessel-size, service, and delivery-timing needs. The figures are from a public report citing Alphaliner data.[8]
Yang Ming: nearly balanced owned and chartered capacity
Owned vessels account for about 65% of Yang Ming's fleet by count but only about 51% by capacity, indicating that its chartered-in vessels are larger on average. Ownership ratios therefore need to be assessed by TEU and vessel-size distribution, not vessel count alone.[6]
Wan Hai: an all-owned fleet at year-end 2025
No. Wan Hai still had four chartered-in vessels at year-end 2024. Newbuilding deliveries and charter redeliveries produced a 100%-owned snapshot at year-end 2025. It reflects fleet renewal at that point in time, not a permanent decision never to charter again.[7]
How can the three structures be interpreted?
| Carrier | Characteristic shown by the public snapshot | Basic interpretation |
|---|---|---|
| Evergreen | Predominantly owned, with a substantial chartered-in fleet | Owned assets support the global network, while charters supplement vessel types and timing. |
| Yang Ming | Nearly balanced owned and chartered-in shares by capacity | A clearly mixed fleet; vessel count and TEU capacity give different impressions. |
| Wan Hai | All vessels owned at year-end 2025 | A fully owned fleet snapshot resulting from newbuilding deliveries and charter redeliveries, not evidence that the carrier will never charter again. |
These three structures cannot be ranked directly as better or worse. They result from company scale, the mix of deep-sea and regional services, the legacy orderbook, charter expiries, vessel age, capital, and past vessel-price and charter-rate cycles.
Common mistakes when reading carrier fleet data#
A 24,000 TEU vessel and a 2,000 TEU vessel differ enormously in capacity. Assess vessel count, TEU, vessel types, and service deployment together.
A charter may last a few months or ten years. A long-term charter can secure capacity, but may offer limited exit flexibility.
The shipowner primarily bears asset and technical responsibilities. The carrier still bears hire, bunker, schedule, customer, and replacement-tonnage risks.
A high ownership ratio provides control and residual value, but also brings capital intensity, vessel-price risk, technological obsolescence, and contraction risk.
Large, well-capitalized carriers also charter many vessels because chartering provides speed, supplementary vessel types, and risk-management benefits.
Ownership buys control; chartering buys time and flexibility#
From first principles, a shipping company's objective is not to maximize vessel ownership, but to obtain sufficient, reliable, and deployable fleet capacity at an appropriate cost.
The current public snapshots of Evergreen, Yang Ming, and Wan Hai illustrate three different positions: Evergreen is predominantly owned with chartered supplements; Yang Ming has nearly balanced owned and chartered capacity; and Wan Hai showed an all-owned fleet at year-end 2025. These differences are not simple measures of quality. They reflect each company's history, services, capital, vessel mix, and market timing.
