Higher education accreditation within the Washington Accord has played a crucial role in advancing the global recognition of engineering training, greatly benefiting the professional sustainability of graduates. However, the existence of substantial disparities in higher engineering education systems among countries poses challenges for international engineering education accreditation, primarily due to information asymmetry. To address this issue, this study focuses on a comparative analysis of representative undergraduate programs in the field of ship engineering from the Ocean University of China in China and the University of Southampton in the UK. By examining the curriculum systems in the field of ship engineering in both countries, this study aims to shed light on the variations and similarities between the two. Moreover, the study delves into the specific example of the “Marine Engineering English” module to illustrate how an independent module can effectively fulfill the requirements for international recognition in higher engineering education accreditation while also serving the curriculum system. Serving as a significant practical case within the framework of the Washington Accord, this research provides valuable insights for the establishment of engineering education curriculum systems that are aligned with international standards. Ultimately, its findings hold considerable significance for promoting the international recognition of engineering education and fostering sustainable professional development for graduates.
