A berth is a designated space in a port or harbor where a vessel docks or moors for loading or unloading cargo. Think of it as a parking spot for ships—each berth is equipped to handle specific vessel types, cargo volumes, and port operations.
In the world of international shipping, berthing availability directly impacts transit times, port congestion, and your shipment’s delivery schedule. Understanding how berths work is essential for importers, exporters, and freight forwarders managing ocean freight.
How Does It Work?
When a vessel arrives at a port, it must be assigned a berth by port authorities. This determines where and when the ship can begin its cargo operations.
Each may include:
- A quay or dock wall where the vessel ties up
- Cranes for container handling or bulk cargo discharge
- Storage space for temporary warehousing
- Customs or inspection facilities for regulated goods
- Berthing windows or time slots reserved for scheduled vessel calls
Berths are managed to optimize port throughput, minimize vessel dwell time, and prevent bottlenecks that can slow down supply chains.
Types of Berths in Commercial Ports
Different types of berths serve different vessel and cargo types. Common examples include:
- Container Berth – designed for containerized cargo and equipped with gantry cranes
- Bulk Cargo Berth – handles dry or liquid bulk like grain, coal, or oil
- Roll-on/Roll-off (RoRo) Berth – used for vehicles and wheeled equipment
- Breakbulk Berth – handles non-containerized, palletized, or heavy-lift cargo
- Multi-purpose Berth – adaptable for various cargo types, often in smaller or regional ports
- Offshore or Anchorage Berth – where ships anchor offshore to wait for availability or transfer via lightering
Why Berth Availability Matters to Shippers
Berthing delays = shipment delays.
When ports are congested—especially during peak season or labor disruptions—vessels may wait at anchor for days before getting a berth. This not only increases transit time but can also lead to:
- Missed delivery windows or production deadlines
- Demurrage and detention charges
- Storage overflows and truck appointment backlogs
- Increased total landed costs
