Abstract: Because of the needs of development on marine energy, marine engineering equipment manufacturing has become the hot competing item among major domestic shipyards. Therefore, this article is mainly compiled to introduce current application situation of nondestructive testing technology in the marine engineering project, and analyse the differences between marine engineering project and conventional ship repairing and shipbuilding project in aspects such as structure type, material, testing standard, testing technician. The state of new nondestructive testing technology application existing in the marine engineering project, as well as its research and development trend at present stage is also discussed.
