Abstract: Graduation design is an important part in the undergraduate teaching process and plays an important role in improving training quality of professional talents and students'comprehensive practical ability. Under the background of national first-class undergraduate major construction, marine engineering major puts forward higher requirements for students'ability to comprehensively apply knowledge to solve complex engineering problems. Based on the CDIO concept, this paper explores the reform of marine engineering graduation design. By introducing the method of“double assistant tutors”between enterprises and universities, the teaching mode of“full process”of graduation design under the mechanism of“double assistant tutors”is discussed. It is expected that the above teaching modes can improve students'ability to solve complex engineering problems, so as to better train professionals who meet the needs of the industry under new situations.
