Voyage Charter, Time Charter or COA: Which Structure Fits the Cargo?

The appropriate charter structure depends on whether a client needs one cargo movement, control of a vessel for a period, or capacity for a repeated shipment program. Voyage charters, time charters and contracts of affreightment allocate costs and risks differently.

Kiev Shipping Ltd assists charterers, cargo interests, shipowners and operators in selecting and negotiating the commercial structure suited to the intended trade.

Voyage charter

Under a voyage charter, the owner agrees to carry an agreed cargo between specified ports or ranges. Freight is usually expressed per metric ton, as a lump sum, or through another agreed basis.

The owner normally controls the vessel and pays voyage expenses, subject to the charter terms. The charterer’s principal obligations include providing the agreed cargo, meeting documentary requirements and performing loading or discharging responsibilities allocated by the charter party.

A voyage charter is commonly used for a single dry bulk, breakbulk, project or tanker cargo when the route and shipment window are defined.

Time charter

Under a time charter, the charterer hires the vessel for an agreed period and directs its commercial employment within contractual trading limits. Hire is normally paid at an agreed daily rate.

The owner generally remains responsible for technical operation, crewing and insurance. The time charterer usually pays bunkers, port costs, canal dues and other voyage-related expenses, subject to the contract.

This structure can suit charterers or operators needing repeated employment and greater scheduling control, but it exposes them more directly to bunker prices, port expenses, off-hire issues and employment risk.

Contract of affreightment

A contract of affreightment, or COA, covers an agreed cargo volume through multiple shipments during a defined period. The performing vessels may change from voyage to voyage if they satisfy the contract.

A COA can support regular commodity flows without committing the charterer to one named vessel for the entire program. Quantity schedules, shipment intervals, nomination procedures and freight adjustment mechanisms must be drafted carefully.

Consecutive voyages

Consecutive voyage arrangements use the same vessel for a sequence of voyages. They require schedules that allow the ship to complete one voyage and return in time for the next cargo.

When ports are far apart or cargo intervals do not match the vessel’s round-voyage duration, treating each shipment as a separate voyage may be more realistic than promising consecutive employment.

Key commercial differences

• Vessel control: greater for the charterer under a time charter.
• Cost exposure: broader voyage-cost exposure under a time charter.
• Volume commitment: central to a COA.
• Scheduling: one defined movement under a voyage charter versus a program under a COA.
• Market risk: allocated differently depending on freight, hire, duration and adjustment clauses.

Questions to answer before choosing

The parties should consider cargo volume, shipment frequency, route, laycan flexibility, vessel requirements, expected market direction and their ability to manage voyage costs.

For project and breakbulk cargo, technical suitability may favor a voyage charter for a specifically approved ship. For regular dry bulk flows, a COA may provide capacity planning. Time chartering is appropriate only where the charterer is prepared to manage vessel employment and associated costs.

Charter-party negotiations

Whichever structure is selected, the recap and charter party must define freight or hire, payment, laytime, demurrage, off-hire, bunkers, port responsibilities, vessel performance, cargo obligations and dispute resolution as applicable.
