2021/11/05

With the development of the economy and technology, China’s shipbuilding industry has been propelled forward and continuously advanced. Today, nondestructive testing (NDT) plays an increasingly significant role throughout the design, production, operation, and repair of ships, serving as a crucial guarantee of construction quality. Therefore, it is highly necessary to establish a comprehensive NDT program during the shipbuilding process. 1. Current Status of NDT Development in China In recent years, as China’s national technological and economic levels have steadily risen, NDT has also experienced leapfrog development. The enhancement of overall national strength has facilitated the advancement of NDT.

With the development of the economy and technology, China’s shipbuilding industry has been propelled forward. Today, nondestructive testing (NDT) plays an increasingly vital role throughout the design, production, operation, and maintenance of ships, serving as a critical assurance of construction quality. Therefore, it is essential to establish a comprehensive NDT program during the shipbuilding process.

1. Current Status of Nondestructive Testing Technology Development in China

In recent years, as China’s national manufacturing and economic capabilities have continued to improve, nondestructive testing (NDT) technology has also undergone rapid and transformative development. The enhancement of China’s overall national strength has created unprecedented opportunities for the advancement of the NDT field, and NDT techniques are now being applied more extensively across a wide range of industries, virtually covering all major industrial sectors, including aerospace, metallurgy, petrochemicals, and shipbuilding, among others. China’s NDT technology has already attained a leading position on the international stage.

2. Application Requirements for Nondestructive Testing Technology in Ship Design

The ultimate quality of shipbuilding is closely linked to ship design. The quality of any product is influenced by the quality of its design; high design quality effectively ensures the reliability of the vessel’s overall performance. In essence, ship design determines the inherent quality of the product. During the ship-design process, designers must take into account the practical applicability of nondestructive testing (NDT) technologies, ensuring that the structural design requirements are well aligned with the key performance characteristics of NDT methods—such as sensitivity and reliability—to thereby guarantee vessel quality. Ship-design departments should establish a dedicated NDT review task force to examine component drawings in the design documentation and the corresponding annotations in relevant documents, including the types of components specified, the NDT methods employed, and the associated operating procedures.

3. Application Requirements for Nondestructive Testing Technologies in Ship Operation

To ensure the reliability of all aspects of operational performance, ship design departments must, in accordance with relevant standards, thoroughly assess the reliability of nondestructive testing techniques employed in shipbuilding, conduct real-time monitoring and inspection of the operational conditions reported by ship operators, and gain a comprehensive and detailed understanding of the technical application conditions. Such an approach facilitates continuous improvement in ship design, thereby enhancing both shipbuilding and maintenance–inspection capabilities, optimizing vessel performance, and extending service life. During the operational phase, fatigue damage is a major cause of vessel failure; therefore, to prolong the service life of aging vessels, it is essential to innovatively develop and implement appropriate nondestructive testing methodologies.

4. Requirements for the Application of Nondestructive Testing Technologies in Shipbuilding

Nondestructive testing (NDT) techniques are also extensively applied in shipbuilding. Shipbuilding constitutes a crucial stage in the overall production process, requiring the design department to submit relevant design drawings and documentation. In addition to procuring the raw materials specified by the design department, the shipbuilding division must conduct NDT inspections in accordance with applicable technical requirements to verify compliance with the technical specifications for NDT in shipbuilding. Throughout the shipbuilding process, personnel from all departments must maintain close communication to ensure that all manufacturing needs are promptly addressed; only in this way can effective coordination be maintained. Moreover, shipbuilding personnel must obtain timely access to relevant NDT information, thereby enabling scientific quality control throughout the manufacturing process.

5. Requirements for the Application of Nondestructive Testing Techniques in Ship Repair

Ships operating at sea are exposed to the external environment for extended periods, making them susceptible to a wide range of problems that can adversely affect their service life. After a certain period of operation, ships must undergo regular inspections and maintenance. During these scheduled maintenance intervals, the relevant authorities should develop rigorous maintenance and inspection plans. For instance, ultrasonic thickness measurements must be conducted on the hull plating, main deck, and internal structural components, while nondestructive testing must be performed on weld quality and propellers. The quality of nondestructive testing directly determines the overall quality of ship repairs, and it is essential to continuously draw lessons from practical experience.

Summary

With the continuous development of China’s shipbuilding industry, the application of nondestructive testing technologies in ship construction, operation, and maintenance will become increasingly widespread. The effective implementation of nondestructive testing can make all stages of shipbuilding and ship operation more scientific and intelligent, thereby promoting the sustainable development of China’s shipbuilding industry and advancing the country’s overall progress.

To further carry forward the spirit of Lei Feng and promote the volunteer ethos of “dedication, friendship, mutual assistance, and progress,” in accordance with the spirit of the Henan Provincial Association for Science and Technology’s “Notice on Launching a Centralized ‘i-Science Popularization’ Science and Technology Volunteer Service Campaign in the Spirit of Lei Feng,” Luoyang Weicheng Engineering Testing Co., Ltd. responded enthusiastically to the call and organized a science popularization event on the safe operation of forklifts. On March 4, our company meticulously planned and conducted an emergency response drill for special equipment—forklift accidents—and invited several nearby companies that use forklifts to observe the exercise. The purpose of this drill was to simulate real-world working conditions, specifically the sudden occurrence of an accident during the process of using a forklift to handle goods.
