In 2011, NIR was developed in the framework of the Paris MoU as a New Inspection Regime, an initiation that drew the attention of many stakeholders and is widely considered an innovation. This New Inspection Regime has the potential to be of considerable influence on enhancing the global PSC inspection system. An assertion can be made with all confidence that proper implementation of the NIR is a sure way to bring about modernization of PSC inspections worldwide. This paper deals with a comparative analysis of periods under the ‘pre NIR’ (before implementation of the NIR) and ‘post-NIR’ (after the NIR was implemented) using inspection data and information from the online database of Paris MoU. The method used for comparison will present overall changes in inspection results and quality of vessels inspected.
