The Role of NDT equipment in shipbuilding and repair

Addressing inspection challenges in shipbuilding and repair

The shipbuilding and repair sector is characterized by its complex and demanding inspection requirements due to the extensive and varied nature of marine structures. Ensuring the integrity and safety of ships and maritime vessels is crucial for operational efficiency and safety on the high seas.

Ship components, including hulls, decks, welds, and machinery, must endure harsh marine environments, making regular and precise inspections vital to avoid costly repairs, enhance safety, and maintain performance standards.

Critical inspection areas:

• Hull integrity: The hull of a ship, which is subjected to constant stress from waves, collisions, and corrosion, requires thorough inspection for cracks, corrosion, and structural integrity. Early detection of issues in the hull can prevent catastrophic failures and ensure the vessel’s seaworthiness.

• Welds and joints: Welds and joints in a ship’s structure are critical for maintaining overall strength and stability. Defects such as porosities, cracks, and incomplete fusion can compromise the vessel's safety. Non-destructive testing (NDT) is essential for detecting these issues and ensuring the quality of welds and joints.

• Decks and bulkheads: Decks and bulkheads must withstand mechanical stress and environmental conditions. Inspecting these components for corrosion, cracks, and delaminations is necessary to ensure they remain structurally sound and functional.

1. Machinery and components: Ship machinery, including engines, pumps, and generators, operates under extreme conditions and is prone to wear and tear. Inspecting these components for defects such as cracks, material thinning, and misalignment is crucial for maintaining operational reliability and preventing breakdowns.

Traditional inspection methods in shipbuilding and repair can be cumbersome and disruptive, often requiring significant downtime or disassembly of equipment. For instance, inspecting the interior of large ship sections or accessing difficult-to-reach welds and joints can be challenging with conventional methods. These limitations can lead to increased operational costs and extended repair times.

TEQTO's solutions for shipbuilding and repair inspections

TEQTO provides a range of advanced non-destructive testing (NDT) equipment designed to tackle the specific inspection needs of the shipbuilding and repair sector.

Metal hardness testers: Our metal hardness testers, utilizing Combined Testing Methods, UCI Testing Method, and Leeb Testing Method, are essential for evaluating the hardness and quality of metals used in ship construction. Accurate hardness testing ensures that hulls, welds, and other critical components can withstand the harsh marine environment.

Magnetic particle flaw detectors: Ideal for detecting surface and near-surface defects in ferromagnetic materials, our magnetic particle flaw detectors are crucial for inspecting welds and structural components in ship hulls and decks. These detectors help identify defects such as cracks and porosities, ensuring the structural integrity of the vessel.

Eddy-current flaw detectors: Leveraging electromagnetic induction, our eddy-current flaw detectors are effective in detecting surface defects and material inconsistencies in conductive components. They are particularly useful for inspecting ship machinery and components, where precision and reliability are essential.

Acoustic flaw detectors: Our acoustic flaw detectors, which use high-frequency sound waves, offer detailed insights into the internal condition of ship components. This method is effective for detecting internal defects in hulls and bulkheads, providing a non-invasive way to assess structural integrity.

Coating thickness gauges: Essential for measuring the thickness of protective coatings on ship hulls and decks, our coating thickness gauges ensure that coatings meet specifications to prevent corrosion and deterioration. Maintaining proper coating thickness is crucial for extending the lifespan of maritime vessels.

Ferrite meters: Measuring ferrite content in welds and materials used in shipbuilding helps assess corrosion resistance and mechanical properties. TEQTO’s ferrite meters provide critical data for ensuring welds and materials meet the rigorous standards required for marine environments.

Crack depth meters: Our crack depth meters are vital for measuring the depth and orientation of surface cracks in ship components. Accurate crack depth measurements assist in planning repairs and preventing failures, ensuring the continued safety and reliability of maritime vessels.

Integrating TEQTO’s advanced NDT tools into your shipbuilding and repair processes enhances the accuracy and efficiency of inspections. Our equipment helps address the sector’s specific challenges, ensuring the structural integrity, safety, and performance of vessels, while reducing downtime and repair costs.
