Structural test, thermal test, ultrasonic test, offshore drop test, water-tightness test, and MPI test are all important methods of evaluating the integrity and reliability of various components and systems in CMContainer. The structural test is used to assess the ability of materials to withstand loads and stresses, while the thermal test is used to determine how materials and components perform under extreme temperature conditions. Ultrasonic testing uses sound waves to detect defects and flaws in materials, while the offshore drop test is used to ensure equipment can withstand the impact of being dropped from a certain height.

The water-tightness test is used to check if a product or system can prevent water from penetrating into it, which is particularly important in the marine industry. Finally, the magnetic particle inspection (MPI) test is used to detect surface and subsurface defects in ferromagnetic materials.

By conducting these tests, engineers and technicians can ensure that products and systems meet the required standards and specifications, and can operate safely and effectively in their intended environment.
