The GradDip (Marine) is designed for students who wish to gain a diploma-level qualification in Marine Engineering. The plan articulates with the MEngSc (Marine) plan.

Students undertaking the Graduate Diploma in Marine Engineering are required to take six coursework courses (36UOC) from the courses set out under the MEngSc in Marine Engineering plan information. As with the Masters, students may elect to either specialise in a particular area or to complete a more broadly based qualification. To qualify for the Graduate Diploma in Marine Engineering, students must take the core courses ZACM8320 Marine Engineering and ZACM8321 Naval Architecture.

Students may, with the approval of the Program Authority, take one course (6UOC) from a related coursework program. The courses ZACM8501 Project Report (Full Year) and ZACM8502 Project Report (Single Session) are not available to candidates for the Graduate Diploma. Not all elective courses will necessarily be available in a particular year.
Students at the Graduate Diploma level are expected to possess the foundation knowledge relevant to the particular areas of engineering they are studying.
