VNS provides ship repair services at Son Duong Port, Vietnam, supporting bulk carriers, coal carriers, ore carriers, and other commercial vessels calling at the port and anchorage. Our services cover mechanical and structural repairs, underwater inspection and cleaning, and engine and electrical work. We also handle tank cleaning, marine equipment servicing, spare parts supply, and load testing. VNS supports vessels at berth and anchorage in Son Duong, with services coordinated around vessel schedules, access conditions, and applicable port requirements.
Son Duong is a deep-water specialized port in Ha Tinh Province, north-central Vietnam, built to serve the Formosa Ha Tinh steel complex within the Vung Ang Economic Zone. The port can receive very large bulk carriers, including capesize vessels up to around 300,000 DWT. These vessels carry coal, iron ore, and other raw materials for steel production. By design capacity, it ranks among the largest specialized industrial ports in Vietnam.
Ship Repair For Vessels Calling At Son Duong
A capesize bulk carrier discharging iron ore or coal at Son Duong follows a schedule tied to the steel complex’s production requirements. Timing, access, and safety conditions all shape when repair work can be carried out, so VNS scopes each job accordingly rather than applying a single port-wide routine. Before mobilizing, we confirm the vessel’s ETA and ETB, working location, access requirements, and any applicable port or terminal permits. We then agree the scope of work directly with the vessel’s Master or Chief Engineer.

Underwater Inspection & Repair In Son Duong
VNS can carry out diving work at Son Duong both at anchorage and alongside the berth inside the port, though the scope differs between the two. Inside the port, our underwater team can carry out underwater inspection and propeller polishing. A wider scope is available at anchorage. This includes underwater welding, steel repair, and replacement of selected equipment such as echo sounders and speed logs. Capesize bulk carriers present a much larger hull and propeller than most vessels VNS attends elsewhere, so this scale is factored into planning from the outset. VNS can also arrange UWILD and other underwater survey work where permitted by the vessel’s classification society and applicable requirements.
Cargo Hold & Tank Cleaning
Bulk carriers calling at Son Duong may carry coal, iron ore, or other raw materials depending on their cargo requirements. Cargo hold cleaning may be required when vessels change cargoes or prepare for their next voyage. We also arrange ballast tank cleaning, bilge water removal, fuel oil tank cleaning, and sludge removal. We coordinate this with licensed waste treatment facilities where required.
Navigation, Safety & Equipment Services
We provide navigation and communication equipment repair, reconditioning, or new installation. This is alongside annual survey and inspection of GMDSS and VDR systems and servicing of firefighting and lifesaving equipment. Given the scale of vessels calling at Son Duong, we usually plan this work well in advance so it can be completed within the confirmed berth window.
Marine Spare Parts
Capesize bulk carriers at Son Duong often carry heavy-duty deck and engine equipment not found on smaller vessels, so sourcing the right part can take extra coordination. We source and arrange delivery of engine, navigation, hydraulic, and electrical equipment. This also covers engine and deck stores, marine tools, safety materials, and deck and cabin supplies. We match delivery to the vessel’s size and schedule.
Load Testing & Survey Support
We carry out load testing using load cells and water bags sized for the heavier-duty deck cranes and grabs typical of capesize bulk carriers, alongside ship condition surveys and general audits. Class or survey attendance is coordinated directly with the relevant classification society where required.
