What Happens During a Container Ship Port Call?

Pre-Arrival Procedures

• Container ships from carriers like Maersk and MSC send advance notice 24-48 hours before arrival with cargo manifests and berth requests.

• Port authorities assign berths based on vessel size, cargo type, and available terminal capacity at facilities operated by companies like APM Terminals.

• Pilots board incoming vessels outside the port to navigate ships safely through harbor channels to assigned berths.

• Customs authorities review cargo documentation and may select containers for inspection before vessels complete docking procedures.

• Container terminals prepare equipment including ship-to-shore cranes and yard equipment for efficient cargo handling operations.

Docking and Securing

Tugboats assist large container ships like COSCO's 20,000+ TEU vessels during final approach and positioning at terminal berths.

Mooring crews secure ships using heavy lines attached to bollards, ensuring vessels remain stable during cargo operations.

Shore power connections at modern terminals like those in Hamburg allow ships to shut down engines and reduce emissions during port stays.

Gangways provide safe access between ships and terminals for crew, officials, and service personnel during port calls.

Safety inspections verify proper securing before cargo operations begin at busy container terminals.

Container Discharge Operations

Ship-to-shore cranes manufactured by companies like Liebherr and Konecranes lift containers from vessels onto terminal transport equipment.

Import containers move from ships to container yards where they await pickup by trucking companies or rail operators.

Refrigerated containers from carriers like Hapag-Lloyd connect to shore power systems to maintain temperature-controlled cargo.

Dangerous goods containers receive special handling procedures and segregated storage areas as required by safety regulations.

Terminal operators like DP World coordinate container movements to optimize yard space and minimize handling delays.

Customs and Documentation

Customs officers may inspect selected containers for security, duty assessment, or regulatory compliance verification.

Electronic documentation systems process cargo manifests, bills of lading, and customs declarations for efficient clearance.

Container seals are verified and recorded to ensure cargo security throughout the international transport process.

Import permits and certificates are validated for restricted goods like food products, electronics, or pharmaceutical items.

Duty and tax calculations are processed for containers requiring customs payment before release to consignees.

Container Loading Operations

Export containers arrive at terminals via truck or rail from shippers throughout the port's hinterland region.

Container yard equipment positions export boxes near ship berths for efficient loading using ship-to-shore cranes.

Weight verification ensures containers don't exceed vessel or port handling capacity limits during loading operations.

Load planning software optimizes container placement on ships for stability, accessibility, and discharge sequence at destination ports.

Dangerous goods containers receive special stowage locations and securing procedures according to maritime safety regulations.

Vessel Services and Maintenance

Bunker fuel suppliers provide marine gas oil or heavy fuel oil to container ships during port stays.

Fresh water suppliers replenish ship tanks used for crew consumption and equipment cooling during ocean voyages.

Waste disposal services remove garbage, oily waste, and sewage in compliance with environmental regulations.

Ship chandlers supply provisions, spare parts, and equipment needed for crew welfare and vessel operations.

Technical services may perform routine maintenance or repairs that can be completed during normal port call durations.

Crew and Administrative Activities

1. Immigration officials process crew changes, shore leave requests, and passport documentation for international vessel operations.

2. Ship agents coordinate port services, handle documentation, and resolve operational issues during port calls.

3. Crew members may go ashore for rest, shopping, or medical appointments during extended port stays.

4. Captain and officers complete port state control inspections and safety compliance verifications as required.

5. Departure Preparations

6. Final cargo securing ensures containers remain stable during ocean voyages between ports on planned routes.

7. Navigation officers file sail plans with port authorities and request pilot services for harbor departure.

8. Engine room crews prepare propulsion and auxiliary systems for sea voyage after completing port call activities.

9. Tugboat assistance helps large container ships safely depart berths and navigate through harbor channels.

10. Port authorities clear vessels for departure after verifying completion of all regulatory requirements.

Port Call Duration Factors

Container volume affects port call length, with larger ships like those operated by MSC requiring 12-24 hours for full cargo exchange.

Terminal efficiency at automated facilities like those in Singapore can reduce port call times compared to traditional operations.

Weather conditions may extend port stays when high winds or rough seas prevent safe cargo handling operations.

Labor availability can impact port call duration, especially during peak seasons or holiday periods.

Economic Impact

Port call efficiency directly affects shipping line operating costs and schedule reliability for global supply chains.

Delayed port calls create cascading effects on vessel schedules and container availability throughout shipping networks.

Efficient terminals like those operated by PSA Singapore attract more shipping line calls and cargo volumes.

Bottom Line: What Happens During a Container Ship Port Call?

Container ship port calls involve complex coordination of cargo handling, customs procedures, vessel services, and regulatory compliance. Efficient port operations minimize vessel time in port while ensuring safe, secure cargo exchange.

Modern container terminals use advanced technology and automation to optimize port call efficiency, supporting global supply chain reliability and shipping line profitability.
