Port and harbor operators manage docking and pier facilities, collect wharfage and dockage fees, maintain waterfront infrastructure, and coordinate vessel arrivals and departures. Day-to-day activity involves vessel scheduling, dock and berth assignment, facility maintenance, and shoreside support — though actual cargo handling and pilotage services are typically performed by separate contractors or stevedores.
