Software defect prediction is a field of study that predicts defects in newly developed software in advance of use, based on models trained with past software defects and software update information using various latest machine learning techniques. It can provide a guide to effectively operate and deploy software quality assurance (SQA) resources in industry practices. Recently, there have been papers that have investigated the industrial application of software defect prediction, but more active research is needed to analyze how this can be applied over diverse domains with different characteristics. In this paper, we present the possibility of applying software defect prediction in the maritime and ocean transportation industries. These are facing challenges to build and deploy the types of emerging transportations such as high-efficiency eco-friendly ships, connected ships, smart ships, unmanned ships, or autonomous ships. In our experiments using actual data collected from the domain, the software defect prediction showed high defect prediction performance with 0.91 accuracy and 0.831 f-measure. This suggests that software defect prediction can be a useful tool to allocate SQA resources effectively in this field.
