Our services include mechanical and structural repairs, underwater inspection and cleaning, engine and electrical work, tank cleaning, marine equipment servicing, spare parts supply, and load testing. As a ship repair company in Dung Quat Port, VNS supports vessels at berth and anchorage.
Dung Quat is a deep-water port in Quang Ngai province, on the central coast of Vietnam. The port area is home to the Dung Quat Refinery, Vietnam’s first oil refinery, alongside the Gemadept Dung Quat container and general cargo terminal and an offshore mooring handling crude oil tankers. It is also home to the Hoa Phat Dung Quat Iron and Steel Complex, with its own dedicated deep-water berths handling iron ore, coal, and steel products for vessels up to around 200,000 DWT. The Dung Quat shipyard is also located in the area. Vessels calling at Dung Quat range from crude oil and product tankers to bulk carriers, capesize ore and coal carriers, and container ships, each with a different schedule and berth or anchorage requirement.

Working Around Dung Quat’s Mix Of Cargo And Vessel Types
Vessels at Dung Quat range from crude oil and product tankers calling at the refinery berths to capesize bulk carriers loading or discharging iron ore, coal, and steel products at the Hoa Phat terminal, plus bulk and container ships at the Gemadept terminal. Each type of call comes with a different schedule and a different set of safety requirements. Before mobilizing, VNS confirms the vessel’s ETA and ETB, working location, access requirements, and any port or terminal permit requirements. Our engineers then confirm the scope of work with the vessel’s Master or Chief Engineer and identify which work can proceed safely at berth or anchorage.

For vessels calling at Dung Quat, whether at anchorage or alongside a wharf, getting the right part on board quickly can determine whether a repair can proceed.

Load Testing & Survey Support
Our team carries out load testing using load cells and water bags for deck cranes, provision cranes, engine room cranes, monorail cranes, and accommodation ladders, along with ship condition surveys and general audits, coordinating with classification societies where certification is required.
