Maritime Trade: Cargo Forecasting and Capacity Essentials


Maritime trade stands out as a significant element of the global economy. Ports are crucial focal points providing services for maritime transportation, and accurate cargo demand forecasts and capacity measurements are essential for their effective operation.

Cargo Demand Forecasting in Ports

Successful service delivery by a port relies on accurate predictions of future cargo demand. To meet this demand, port authorities determine the size and diversity of the infrastructure, superstructure, and equipment. Sound demand forecasting is crucial to prevent excess capacity or the inability to meet demand.

For example, if a bulk cargo port expects to process 1 million tons of cargo per year but has a capacity of 3 million tons, it will generate surplus capacity. On the other hand, miscalculating the demand may cause a port to fail in meeting it, potentially resulting in the loss of customers to competitors.

Methods for Cargo Demand Forecasting

Methods used for cargo demand forecasting generally fall into two main categories: qualitative and quantitative. Qualitative methods consider opinions and experiences of specific individuals, while quantitative methods utilize statistics and data from previous years.

To make predictions reliably, it’s common to supplement quantitative methods with qualitative methods. Comprehensive forecasts take into account expert opinions, strategic agreements in the region, developments in transportation infrastructure, and assessments of global/regional crises and legislative changes affecting the logistics sector.

Capacity Measurement in Ports

Accurate capacity measurement and planning are critical for a port to effectively provide services. Port capacity is determined by existing infrastructure, superstructure, equipment, and workforce. However, due to the diversity of services provided to both cargo and ships, capacity measurement is a complex process.

Fundamental Port Capacities

  1. Cargo Handling Equipment Capacity: Indicates the amount of cargo the existing equipment can handle.
  2. Ship Berthing Capacity: Indicates the number of ships that can dock at existing piers and docks.
  3. Storage Capacity: Represents the amount of cargo that can be stored in port storage areas.
  4. Gate Capacity: Represents the number of vehicles that can pass through port gates in a given time frame.

Each of these capacities should be calculated separately, and the lowest figure among them should be considered as the port’s capacity. For instance, if a port has an annual cargo handling capacity of 1 million tons but other capacities are lower, the port’s capacity would be considered as 1 million tons.


In maritime trade, accurate cargo demand forecasts and capacity measurements are crucial for ports to effectively provide services. Accurate predictions are essential to prevent excess capacity and customer loss. Therefore, port managers should collaborate with specialized teams in demand forecasting and capacity planning, making strategic decisions considering the constantly changing trade conditions.
