Shipping Operations and Port Management
What the exam tests
Shipping Operations and Port Management tests the ship-port interface: port calls, berth allocation, cargo handling, container terminal flow, stowage, documentation and turnaround performance.
Core rules
- A port call involves arrival notice, pilotage, tugs, berthing, customs, immigration and quarantine clearance, cargo operations and departure. Delay in any link raises port time and costs.
- Container terminals move boxes through quay cranes, internal trucks, yard cranes and gates. Productivity is often measured in moves per crane-hour or berth moves per hour.
- Stowage planning balances stability, stress, cargo access, segregation, lashing and dangerous-goods rules. A container ship may be planned by bay, row and tier.
- TEU is a twenty-foot equivalent unit; a 40-ft container is two TEU but one physical box. Moves and TEU are not interchangeable.
- Incoterms allocate cost, risk and logistics duties between buyer and seller; they do not by themselves transfer ownership.
Worked example
A terminal must load 1,200 moves. Four quay cranes work at 30 moves per crane-hour. Ideal time = 1,200 / (4 × 30) = 10 hours. If crane availability is 90%, effective crane-hours fall, so time = 10 / 0.90 = 11.1 hours. Add delays for hatch changes, lashing, weather and yard congestion. The calculation shows why small productivity losses have a large effect on berth occupancy.
Traps
Do not mix moves with TEU. Do not assume all cranes work the same hatch or that productivity is constant. Berth time is not the same as total port time. Incoterms do not determine title. A fast quay crane is useless if yard or gate flow is the bottleneck.
