Port Sizing and Operations: Key Factors and Considerations

Port Sizing: Key Factors

Physical Factors

1. Oceanographic and Meteorological Conditions

These conditions define navigational restrictions. Wind conditions are classified as:

• Soft: Up to 36 kph
• Moderate: 36 - 63 kph
• Severe: 63 - 108 kph

2. Vessel Dimensions

Design vessel dimensions (LOA, breadth, freeboard, draft) are crucial for port design.

3. Vessel Maneuverability

• High: Light war vessels, cruises, bulk carriers, Ro-Ro vessels, first-generation containerships
• Medium: Modern war vessels, oil carriers (T-2), bulk carriers, second-generation containerships
• Low: Aircraft carriers, VLCC tankers, third and fourth-generation containerships, older or damaged vessels

4. Vessel Squat

Two main effects:

• Vertical movement (sinking)
• Longitudinal rotation

5. Vessel Movements

Tide action causes six movements (three angular, three linear) impacting port dimensions.

Human Factors

1. Vessel Control

Human expertise in maneuvering vessels is critical.

2. Navigational Aids Efficiency

These aids (on sea, vessel, or land) facilitate safe and efficient port operations.

Port Operations

Definition

Port activity encompasses:

• Construction, operation, and administration of ports, terminals, dredging, and seawater public works.
• Activities in ports, terminals, loading/discharging areas, beaches, and shores.

Planning Considerations

Key aspects for planning port operations and activities include:

• Discharging
• Transportation
• Storage in transit
• Delivery
