Case of Ship Structure Safety Assessment

Background: In the structural safety assessment of some aged ships, the mechanical properties of ship - plate steel may change due to the long - term effects of seawater corrosion, alternating stresses, and other factors. Traditional testing methods such as taking samples directly from the ship structure for tensile testing would cause damage to the ship structure and are costly. Therefore, ultrasonic testing has become a feasible non - destructive testing method.

Case of Application in New Ship Construction Process

Background: During the construction process of new ships, it is necessary to conduct quality inspections on each piece of ship - plate steel to ensure that its performance meets the design requirements of the ship. Ultrasonic testing can quickly screen out steel plates that may have performance problems, reducing the risks in subsequent construction.

Specification range:

Thickness:1.5-200mm

Width:1500-4000mm

Length:5000-15000mm

 

 

 

Testing Process: After the ship - plate steel enters the shipyard, ultrasonic testing is carried out on it before processing. The inspectors evenly arrange inspection points on the surface of the ship - plate steel according to certain testing specifications and use high - precision ultrasonic testing instruments for testing. For example, during the construction of a large oil tanker, strict ultrasonic testing is carried out on the ship - plate steel used for key parts of the hull such as the bottom and the side.

Acceptance Decision and Subsequent Measures: Based on the results of ultrasonic testing and the relevant standards requirements of classification societies, etc., it is decided whether the ship - plate steel can be used for ship construction. If the ultrasonic testing shows that there are doubts about the performance indicators such as the yield strength of the ship - plate steel, the shipyard can ask the supplier to provide further quality proof documents or conduct supplementary testing (such as sampling tensile testing). Through this way, the quality of the ship - plate steel used for new ship construction is ensured to be reliable, laying the foundation for the safety and durability of the ship.
