To maintain the quality and durability of TLS offshore containers, we employ a range of NDT methods to inspect welds. Here are some of the primary methods used in the industry:
- Visual Inspection: The most straightforward approach, visual inspection involves examining the weld surface for visible defects such as cracks, undercuts, and improper welding techniques.
- Ultrasonic Testing: This method utilizes sound waves to penetrate the weld and detect internal flaws that may not be visible on the surface, such as inclusions or porosity.
- Magnetic Particle Testing: Widely used by TLS, this technique involves applying a magnetic field to the welded area and then coating it with magnetic powder. Any surface or near-surface defect disrupts the magnetic field, causing the powder to accumulate at the defect, making it easy to detect.
- Radiographic Testing: By using X-rays or gamma rays, radiographic testing can capture images of the weld, revealing internal discontinuities and enabling detailed inspection of the weld’s structure.
- Eddy Current Testing: This technique is effective for detecting surface cracks in conductive materials. It works by inducing currents that create a magnetic field, revealing flaws as changes in the electrical flow.

Magnetic Particle Testing (MPT) is one of the preferred NDT methods we employ due to its reliability in detecting surface and near-surface flaws, crucial for offshore containers. Here’s an overview of our MPT process:
- Surface Preparation: We begin by cleaning the container surface, removing any grease, dirt, or impurities that might interfere with the inspection.
- Applying Magnetic Powder: A fine layer of magnetic powder is evenly applied to the surface, usually consisting of iron and magnetic particles.
- Magnetization: The container is placed in a magnetic field, which may be constant or alternating based on inspection requirements.
- Flaw Detection: A light source or magnetic probe helps visualize the magnetic powder distribution, revealing any cracks or imperfections on the surface.

As an important tool for offshore operations, offshore containers must undergo strict testing and maintenance to ensure their safety and reliability. NDT is an important method for offshore container inspection，which can effectively detect defects, cracks and fatigue on the surface of containers, and ensuring the reliability and safety of the container.
Some common methods of NDT for offshore containers are: ultrasonic testing (UT), magnetic particle testing (MPT), eddy current testing (ECT), X-ray testing.
TLS usually adopts the method of MPT. This detection is based on the adsorption characteristics of magnetic powder under the action of a magnetic field. By coating a layer of magnetic powder on the surface of the container and detecting the distribution of the magnetic powder under the action of a magnetic field, it reveals cracks and defects. The specific detection process is as follows:
