The university's current Structure and Development Plan (Struktur- und Entwicklungsplan) defines internationalisation as a strategic focus. The Department of Mechanical and Process Engineering pursues numerous activities in this area.

In order to prepare students for a career in a globalizes environment, the department strongly recommends that they spend some time abroad as "outgoings" within the framework of study semesters at one of the numerous partner university, internships and producing their final theses. Conversely, "incomings", i. e. exchange students from a university, are welcome in Offenburg. Detailed information can be found on the pages Study Abroad and Study in Offenburg. The department also encourages its lecturers and employees to spend periods abroad as part of staff mobility.

In addition, the faculty offers four master's degree courses in Biotechnology (MBT), Energy Conversion and Management (ECM), Process Engineering (MPE) and Power Data Engineering (PDE), the teaching and learning language of which is English. For more information, see also Study in Offenburg.

Theses activities are carried out in cooperation with the university's International Center with its International Office and Graduate School sections. The departmental contact persons at the interface between department and International Center are the international relations officers.

For example, the foreign delegates check and authorize the learning agreements of incoming and outgoing exchange students. Subjects to be taken at the respective host university are specified in these so that they can be recognised as equivalent academic achievements if passes successfully at the home university.

The faculty regularly participates in international competitions with students projects such as "Sweaty" and "Schluckspecht".

In cooperation with the Polish University of Warmland and Masuria (UWM) in Olsztyn, the department organizes the international conferences Environmental Best Practices and publishes the English language journal Environmental Biotechnology.
