MARINE WORKSHOP FABRICATION​

Precision Engineering by Bacviet Shiprepair Company

In the dynamic world of marine engineering, the reliability and performance of mechanical components play a crucial role in the safe and efficient operation of vessels and offshore systems. At Bacviet Shiprepair Company  our dedicated marine workshop delivers specialized services in fabrication, reconditioning, and modification of mechanical and machinery parts, serving shipowners, fleet managers, and industrial clients across Vietnam and beyond.

Image for Marine Fabrication Workshop in Haiphong Vietnam

Precision Fabrication for Marine Machinery

Our workshop provides custom fabrication services for a wide range of mechanical components used in marine and offshore applications. With deep expertise and modern equipment, we manufacture parts that meet strict dimensional tolerances and material requirements, supporting both new installations and spare part needs.

We fabricate components such as:

• Shaft sleeves and bushings
• Pump casings and impellers
• Flanges, couplings, and adapters
• Engine supports and brackets
• Gearbox components and drive system parts
• Custom mechanical fittings for marine equipment

All fabricated parts are produced in accordance with international marine standards, using materials suitable for harsh offshore environments such as bronze, stainless steel, cast iron, and special alloys.

Reconditioning – Restoring Value to Worn Components

Instead of replacing worn-out parts, Bacviet Shiprepair Company offers a cost-effective alternative: reconditioning. This service involves restoring existing mechanical components to original specifications through machining, rebuilding, and precision finishing.

Our reconditioning services include:

• Bearing housing repair and resizing
• Shaft journal buildup and re-machining
• Pump impeller refurbishment
• Valve body and seat repair
• Surface treatment (metal spraying, grinding, polishing)
• Crack detection and repair (including dye penetrant and magnetic particle testing)

Reconditioned parts are tested and inspected to ensure reliability and extended service life, helping clients reduce downtime and save on costly imports or replacements.

Modification for Operational Optimization

Marine systems often require modification to meet changing operational requirements or to adapt older systems to newer technologies.Bacviet Shiprepair’s workshop supports clients with tailored mechanical modifications that improve functionality, efficiency, or compliance.

Examples of our modification work:

• Altering mounting dimensions to match new equipment
• Modifying pump or motor housings to support retrofitted systems
• Adapting mechanical seals and couplings for improved performance
• Upgrading legacy parts to meet modern safety or efficiency standards

All modification projects are carried out with a combination of engineering consultation, reverse engineering (if drawings are unavailable), and precision machining.

Workshop Capabilities

Our workshop is fully equipped with a wide range of tools and machinery to ensure versatility, precision, and quality:

• CNC lathes and milling machines
• Vertical and horizontal boring machines
• Surface grinding and honing machines
• Dynamic balancing machines
• Hydraulic presses and keyway slotting tools
• TIG, MIG, and arc welding stations
• NDT and dimensional inspection equipment

We also offer reverse engineering services for obsolete or undocumented parts, using 3D scanning, measurement tools, and CAD modeling.

Experienced Team, Proven Quality

Bacviet Shiprepair Company's marine workshop is powered by a team of skilled technicians, machinists, and mechanical engineers with years of experience in marine systems. Our workflow is guided by strict quality control processes and documentation at every step — from material selection to final inspection.

We work closely with classification societies and client representatives to ensure compliance with standards such as:

• ABS, DNV, Lloyd’s Register
• ISO 9001 Quality Management

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.
