Contract of Affreightment: freight certainty for cargo that keeps moving.

When you ship the same commodity again and again, leaving freight to the spot market is a risk you don't need to take. A COA locks in capacity and price across your program.

The Fundamentals

What is a Contract of Affreightment?

A Contract of Affreightment is an agreement in which a carrier commits to transport a defined quantity of cargo, over a defined period, between agreed routes — at pre-agreed freight terms — without tying the commitment to a single named vessel.

Instead of fixing one ship for one voyage, a COA covers many shipments over months or years. The cargo owner gains assured capacity and predictable cost; the freight provider optimises tonnage across the program. As a fleet-independent specialist, Sunrise Maritime structures and executes COAs purely around your cargo economics.

Why It Works

Five reasons cargo owners choose a COA

Freight Stability

Pre-agreed rates remove exposure to spot-market swings.

Capacity Security

Guaranteed tonnage when you need it, even in tight markets.

Long-Term Visibility

A multi-year horizon you can build supply-chain plans around.

Cost Optimization

Program-level scale and planning drive freight cost down.

Supply-Chain Reliability

Dependable cargo flow that protects downstream commitments.

01

Cargo Evaluation

We map volumes, commodities, seasonality, packaging, and your commercial objectives — the foundation every sound COA is built on.

02

Route Assessment

Ports, drafts, restrictions, and rotations are assessed to define the most efficient and reliable trade lanes for your program.

03

Freight Modelling

Using live market intelligence, we model freight across vessel classes and structures — fixed, indexed, or hybrid — to fit your risk appetite.

04

Vessel Alignment

We align suitable vessel classes and owner relationships to the program — fleet-independent, so the choice is always cargo-led.

05

Contract Structuring

Laycan spreads, nomination mechanics, demurrage/despatch, escalation and performance terms are structured for clarity and fairness.

06

Execution

Each shipment is nominated, fixed and operated under the COA — with our desk managing voyages end to end, 24/7.

07

Performance Monitoring

We track performance against the contract, report transparently, and continuously optimise as markets and volumes evolve.
