1: Brief Historical Background 1

Mechanical Engineering is one of the broadest of the engineering disciplines. In University of Port Harcourt, the Department of Mechanical Engineering was established in 1986 as the last of the five (5) Departments in the Faculty of Engineering.  Studying Mechanical Engineering offers students a wide choice of options in industry. The University of Port Harcourt produced its first graduates in Mechanical Engineering in 1991/92 session.

The undergraduate programme in Mechanical engineering is for a minimum duration of five (5) academic years and a maximum duration of seven (7) academic years.  On successful completion of the programme and fulfillment of other University requirements, a Bachelors of Engineering degree in Mechanical Engineering (B.Eng., Mech. E) is awarded.

The Department has made three revisions of the courses it offers in its programme of study since inception to keep abreast with the dynamics of the profession as well as to meet the requirements of both the Council for the Regulation of Engineering in Nigeria (COREN), the National University Commission (NUC) and the University Senate.

The Department also supports postgraduate programmes leading to Masters of Engineering in Mechanical Engineering (M. Eng, Mech. Engr.) with options in Applied Mechanics and Design, Engineering Materials Design, Industrial and Production Engineering, and Thermofluid Engineering, and Doctor of Philosophy in Mechanical Engineering (PhD, Mech. Engr.).
