When inspection is conducted in the fields of design and manufacturing, how well that inspection is carried out is as important as how well the design and manufacturing are done. It is important that we consider how well a product is inspected in the offshore industry because offshore structures are operated far from center of operations. This paper presents a fast and effective inspection system to guarantee product performance after the design and manufacturing process by using Mixed Reality (MR) and Ubiquitous Sensor Network (USN).
