Steel Plate Renewal and Outfitting Fabrication Services for Ocean-Going Vessels in Vietnam

1- The Importance of Structural Steel Work on Board

A vessel’s strength and seaworthiness depend heavily on the condition of its steel structure. From hull plating to deck reinforcements and fabricated outfitting parts, steel components endure constant stress: seawater corrosion, cargo impact, weather exposure, and mechanical fatigue. If damaged or neglected, these areas can compromise safety, delay operations, and even lead to detention by port authorities or classification societies.

For shipowners and fleet managers, ensuring reliable partners for steel plate renewal, hull repairs, and outfitting fabrication at every port of call is essential. Vietnam has emerged as one of Asia’s most strategic service hubs, offering fast, cost-effective, and Class-approved steel repair services to vessels trading internationally.

2- What We Deliver to Shipowners

Unlike traditional shipyards that require long docking schedules, Bacviet Shiprepair provides flexible, mobile ship repair solutions. Our services cover:

  • Onboard steel replacement during cargo operations at berth or anchorage.

  • Prefabrication in workshops followed by quick installation onboard.

  • Emergency hull steel insert repairs approved by Class surveyors.

  • Fabrication of customized outfitting components to replace damaged or obsolete parts.

  • 24/7 attendance at all Vietnamese ports with short mobilization time.

This approach minimizes downtime and keeps vessels fully compliant with international regulations.

3- Comprehensive Range of Steel Services

Hull plating and structural inserts are often the most urgent repair items during Class surveys or PSC inspections. We provide:

  • Renewal of side shell, bottom, and bilge plates using certified marine-grade steel.

  • Tank top steel repair in cargo holds or engine room double bottoms.

  • Bulkhead inserts to restore watertight integrity in ballast tanks.

  • Edge preparation, full-penetration welding, and NDT (ultrasonic, MPI) as required by Class.

All welding consumables are sourced from approved manufacturers, and welding procedures are strictly certified.

3.2. Deck Repairs and Strengthening:

Deck areas suffer constant wear from cargo gear, weather, and machinery. Our teams are experienced in:

  • Renewing corroded deck plates and reinforcing stiffeners beneath.

  • Repairing hatch coamings, covers, and access manholes.

  • Strengthening forecastle deck structures supporting anchor windlass and mooring winches.

  • Replacing accommodation deck plating, ensuring safety for crew areas.

Repairs are often carried out during loading or discharging to save time.

3.3. Fabrication of Outfitting Components:

Outfitting items are critical for ship operation and crew safety. We design, fabricate, and install:

  • Pipe supports, gratings, handrails, ladders, and platforms.

  • Ventilation trunks, ducts, and air casings made from stainless or galvanized steel.

  • Watertight and weathertight doors, hatch covers, and access lids.

  • Custom machinery foundations and brackets for deck equipment.

  • Mooring and towing fittings such as bollards, chocks, and fairleads.

Our workshops are equipped with CNC plasma cutting machines, plate rollers, and bending presses to achieve high-quality fabrication.

3.4. Riding Squads for Onboard Works:

Bacviet maintains a network of riding repair teams who can join ships at anchorage or en route. These squads are fully self-sufficient, carrying portable welding machines, cutting torches, and generators.

They can perform:

  • Steel insert fitting inside tanks and confined spaces.

  • Pipe rack and outfitting replacement while the vessel is sailing between ports.

  • Emergency hull reinforcement after collision or grounding incidents.

This flexibility saves shipowners from costly off-hire periods.

  • North: Hai Phong, Cai Lan, Hon Gai, Cam Pha, Nghi Son, Son Duong.

  • Central: Da Nang, Dung Quat, Quy Nhon, Van Phong, Vinh Tan.

  • South: Vung Tau, Phu My, Ho Chi Minh City, Long An, Can Tho.

Wherever your ship anchors, our teams mobilize locally, reducing response time and logistics costs.

5- Examples of Completed Projects

Some typical assignments carried out at Vietnamese ports include:

  • Renewal of 1,200 m² deck steel plates for a bulk carrier at Son Duong anchorage.

  • Emergency shell plating insert (15mm thick, 3 × 2 m) after side collision at Hai Phong.

  • Installation of new steel gangways, gratings, and handrails for a container ship in Vung Tau.

Comprehensive Ship Motor and Generator Repair Services in Vietnam Ports and Anchorages

Introduction

When a vessel calls at a port in Vietnam, time and reliability are everything. Unexpected failures of electric motors, generators, or power distribution systems can cause costly delays, affect cargo operations, or even compromise safety on board.

Bacviet Shiprepair and its nationwide network of workshops and riding teams have earned the trust of global shipping companies by offering 24/7 emergency repair and preventive maintenance services at all major Vietnamese ports and anchorages. From Hai Phong in the North to Vung Tau and Ho Chi Minh City in the South, our coverage ensures rapid attendance and professional solutions whenever your vessel needs assistance.

A- Scope of Services

1. Electric Motor Repair and Rewinding:

MAIN ENGINE TURBOCHARGER OVERHAULING IN VIETNAM

Precision • Performance • Reliability

At Haiphong Shiprepair Company (Bacviet Commercial & Shiptech JSC), we understand that the marine turbocharger is the heart of a ship’s propulsion efficiency.
A properly serviced turbocharger ensures maximum power output, improved fuel economy, and compliance with IMO emission standards.

Our Marine Turbocharger Overhaul Services are designed to restore every component to OEM condition, guaranteeing reliability, safety, and performance — even in the harshest marine environments.

Marine Turbocharger Overhaul Services By Bacviet Shiprepair

1. Why Turbocharger Overhaul Matters

Marine turbochargers operate under extreme thermal and mechanical loads, spinning up to 20,000–30,000 RPM in continuous operation.
Over time, carbon deposits, corrosion, and bearing wear can degrade performance and risk catastrophic failure.

A professional overhaul provides measurable benefits:

  • Prevents sudden breakdowns and costly downtime
  • Restores full engine performance and fuel efficiency
  • Extends component lifespan and reliability
  • Maintains compliance with IMO and Class emission standards
  • Reduces long-term maintenance and operating costs

Regular overhaul is not only maintenance — it is a strategic investment in your vessel’s long-term health.

2. Our Turbocharger Overhaul Capabilities

Haiphong Shiprepair provides complete overhaul services for all major turbocharger types and brands, including:
ABB, MAN, Mitsubishi, Napier, KBB, PBS, MET, and IHI.

Our services are available onboard, at anchorage, or in our Haiphong workshop, depending on client preference and vessel schedule.

3. Turbocharger Overhaul Procedure

Step 1 – Disassembly and Detailed Inspection

Once the turbocharger arrives at our facility or is accessed onboard, our certified engineers carry out a systematic disassembly.
Each part is cleaned and inspected visually and dimensionally for wear, cracks, imbalance, or thermal stress.

Key inspections include:

  • Rotor shaft and journal condition, run-out measurement
  • Bearing and oil seal wear analysis
  • Casing, nozzle ring, and diffuser examination for erosion
  • Compressor and turbine blades checked for pitting, corrosion, and foreign object damage

A detailed inspection report with photos and measurements is prepared and submitted to the shipowner for full transparency.

Step 2 – Cleaning, Restoration, and Balancing

All components are restored using advanced cleaning technologies:

  • Ultrasonic and chemical cleaning for oil and carbon removal
  • Glass bead and grit blasting for rust and oxide removal
  • Anti-corrosion surface treatment
  • Dynamic balancing of the rotor assembly (Vibration Grade ISO 1940)
  • Reconditioning or OEM replacement of worn parts (bearings, oil seals, blades, nozzle rings, casings, etc.)

If necessary, we perform machining and precision measurements to restore original tolerances according to OEM specifications.

Step 3 – Reassembly, Testing, and Quality Assurance

Reassembly is performed under strict quality control, following OEM procedures and class requirements:

  • Accurate alignment and clearance measurement (axial/radial)
  • Dynamic balancing verification
  • Air and oil leak tests
  • Trial run and vibration test (when applicable)

All overhauls are documented with full traceability records, meeting the inspection standards of ABS, DNV, LR, BV, NK, and KR.

4. Onboard and Workshop Services

We provide two flexible options depending on the vessel’s schedule:

Onboard Overhaul Services

Our mobile service teams are available 24/7 to perform turbocharger overhauls at all Vietnamese ports and anchorages, including Hai Phong, Cai Mep–Thi Vai, Vung Tau, Dung Quat, Nghi Son, and Son Duong.
Our riding squads are trained to perform safe, class-compliant repairs while the vessel remains in operation.

Our specialists hold years of field experience in turbocharger and marine engine maintenance, following strict international standards and ISO 9001:2015 quality procedures.

We ensure each overhaul is witnessed or accepted by Class surveyors upon request, guaranteeing full compliance and traceability.

Ultrasonic Testing  (UT) 

Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more. To illustrate the general inspection principle, a typical pulse/echo inspection configuration as illustrated below will be used.

A typical UT inspection system consists of several functional units, such as the pulser/receiver, transducer, and display devices. A pulser/receiver is an electronic device that can produce high voltage electrical pulses. Driven by the pulser, the transducer generates high frequency ultrasonic energy. The sound energy is introduced and propagates through the materials in the form of waves. When there is a discontinuity (such as a crack) in the wave path, part of the energy will be reflected back from the flaw surface. The reflected wave signal is transformed into an electrical signal by the transducer and is displayed on a screen. In the applet below, the reflected signal strength is displayed versus the time from signal generation to when a echo was received. Signal travel time can be directly related to the distance that the signal traveled. From the signal, information about the reflector location, size, orientation and other features can sometimes be gained.

 

Ultrasonic Inspection is a very useful and versatile NDT method. Some of the advantages of ultrasonic inspection that are often cited include:

 + It is sensitive to both surface and subsurface discontinuities.

 + The depth of penetration for flaw detection or measurement is superior to other NDT methods.

 + Only single-sided access is needed when the pulse-echo technique is used.

 + It is highly accurate in determining reflector position and estimating size and shape.

 + Minimal part preparation is required.

 + Electronic equipment provides instantaneous results.

 + Detailed images can be produced with automated systems.

 + It has other uses, such as thickness measurement, in addition to flaw detection.

As with all NDT methods, ultrasonic inspection also has its limitations, which include:

 + Surface must be accessible to transmit ultrasound.

 + It normally requires a coupling medium to promote the transfer of sound energy into the test specimen.

 + Materials that are rough, irregular in shape, very small, exceptionally thin or not homogeneous are difficult to inspect.

 + Cast iron and other coarse grained materials are difficult to inspect due to low sound transmission and high signal noise.

 + Linear defects oriented parallel to the sound beam may go undetected.

 + Reference standards are required for both equipment calibration and the characterization of flaws.

Magnetic Particle Testing - (MT)

Magnetic particle inspection (MPI) is used for the detection of surface and near-surface flaws in ferromagnetic materials. A magnetic field is applied to the specimen, either locally or overall, using a permanent magnet, electromagnet, flexible cables or hand-held prods. If the material is sound, most of the magnetic flux is concentrated below the material's surface. However, if a flaw is present, such that it interacts with the magnetic field, the flux is distorted locally and 'leaks' from the surface of the specimen in the region of the flaw. Fine magnetic particles, applied to the surface of the specimen, are attracted to the area of flux leakage, creating a visible indication of the flaw. 

The materials commonly used for this purpose are black iron particles and red or yellow iron oxides. In some cases, the iron particles are coated with a fluorescent material enabling them to be viewed under a UV lamp in darkened conditions.

 

Penetration Testing - (PT)

          Much of the confusion surrounding penetration testing stems from the fact it is a relatively recent and rapidly evolving field. Additionally, many organisations will have their own internal terminology (one man's penetration test is another's vulnerability audit or technical risk assessment).

At its simplest, a penetration-test (actually, we prefer the term security assessment) is the process of actively evaluating your information security measures. Note the emphasis on 'active' assessment; the information systems will be tested to find any security issues, as opposed to a solely theoretical or paper-based audit.

The results of the assessment will then be documented in a report, which should be presented at a debriefing session, where questions can be answered and corrective strategies can be freely discussed.
