Why Hon Gai Port Is a Key Destination for Shipowners

Strategic Location

Hon Gai is located at the heart of Quang Ninh Province, on the main international sea route across the Gulf of Tonkin. It is also adjacent to Vietnam’s largest coal industry zone, which generates significant shipping activity. Its location allows vessels to:

• Reduce voyage time on international routes.
• Optimize fuel consumption and operational costs.
• Combine multiple operations, including cargo handling, passenger embarkation, and technical maintenance.

Compared to Hai Phong Port, which is heavily congested with container and feeder vessels, and Cai Lan Port, which specializes more in bulk cargo, Hon Gai offers a more versatile setup. It can accommodate a wide variety of ship types while still maintaining the infrastructure and anchorage capacity to support repair and maintenance activities directly at port or offshore anchorage.

Traffic Volume and Vessel Types

Hon Gai receives a diverse mix of vessels, including bulk carriers, container ships, passenger vessels, and offshore service units. The density of vessel calls here is higher than most neighboring ports, which translates into a constant demand for repair, maintenance, and spare parts supply.

For HMS, this environment provides the opportunity to support multiple ship types simultaneously, from international liner operators to regional bulk carriers, enhancing the scope of cooperation with domestic and global shipowners.
