Shifting (berth)
Movement of a vessel from one berth to another within the same port, typically without loading/discharging operations underway.
In practice
Routine for berth congestion, draft restriction, or cargo rotation. Mate's plan goes to bridge and engine room; pilot orders main engine standby. Most ports charge a fixed shifting fee plus tug time.
Regulatory detail & full definition
Requires pilot, tugs, and a fresh NOR if cargo operations resume at the new berth. Cost: pilotage + tug + agency time + lost laytime. Charterers and shippers usually pay; charter party usually covers compensation in 'shifting clause'. Common reason: terminal congestion or specialist cargo handling at the new berth.
