Nha Trang Port, Vietnam – Overview and Maritime Importance

Nha Trang Port (Coordinates: 12°13′40″N, 109°12′30″E) is located on Vietnam’s southeastern coast, within Khanh Hoa Province. The port serves as a key maritime gateway in the South-Central region, supporting both commercial shipping and tourism operations.

Port Specifications and Facilities

• Total berth length: 480 meters (two main berths)

• Maximum draft: 8.5 meters – suitable for vessels up to 20,000 DWT

• Management: Nha Trang Port Authority, under Khanh Hoa Maritime Administration

• Available services: fuel bunkering, freshwater supply, waste collection, and crew change support

Strategic Role in Vietnam’s Marine Network

With natural shelter and stable weather, Nha Trang Port provides optimal conditions for offshore vessel repair, maintenance, and supply operations.
It also connects major Vietnamese sea routes from Hai Phong to Ho Chi Minh City, forming a vital hub for marine logistics and ship repair in Vietnam.

The port’s deep-water draft supports general cargo vessels, bulk carriers, container ships, and cruise liners. Calm sea conditions and protective surrounding islands enhance safety and accessibility for marine service operations throughout the South China Sea.

Case Study: GRAB Welding Repair – Nha Trang Port

At Nha Trang Port, HMS – Haiphong Marine Services successfully completed an urgent GRAB welding repair for a cargo handling unit onboard a vessel. During the inspection, our certified technicians identified four critical weld fractures on the grab frame structure. The repair procedures were carried out in accordance with WPS-GUVEN-BW-001 to BW-003, following EN ISO 15609-1 standards to ensure class compliance and structural integrity.

The damaged areas were first cleaned using grinding machines to remove rust, old coating, and cracks before welding. HMS welding specialists then performed full penetration welding, followed by visual and dye penetrant testing (DPT) to verify weld soundness. All work was executed under strict quality control and safety supervision.

Upon completion, the grab was reinstalled and tested during night cargo operations, confirming full operational efficiency and safety performance. This project highlights HMS’s capability to deliver class-approved welding and structural repairs promptly at port, ensuring vessels can resume cargo handling without delay.
