Special Issue Information

Dear Colleagues,

With the rapid advancement of sensing technology, information technology, and decision theory, the engineering systems within the domain of ocean engineering are progressively becoming increasingly intricate. The levels of integration and intelligence of these systems continue to advance, resulting in escalating costs in terms of design, production, and particularly maintenance and assurance. Concurrently, owing to the surge in the number of components and influencing factors, the likelihood of faults and functional failures is gradually also rising. Consequently, the focus of researchers has shifted towards the intelligent maintenance and health management of ocean engineering equipment.

Grounded in considerations of the reliability, safety, and economy of complex systems, there is a growing emphasis on the application of fault prediction and health management strategies. Prognostics and health management (PHM), as an emerging interdisciplinary field and comprehensive set of technologies, is spearheading a transformative phase in the maintenance of and support systems for such equipment. Developing the intelligent maintenance of equipment can ensure the secure, stable, and reliable operation of ocean engineering equipment, enhancing personnel safety and manufacturing sector production efficiency and yielding tangible economic and social benefits.

In recent years, with the swift evolution of artificial intelligence technology and its remarkable advantages in feature extraction, knowledge learning, and intelligence, new avenues have been paved for intelligent operation, maintenance, and health management. The integration of artificial intelligence algorithms into research on intelligent maintenance and health management has achieved remarkable strides.

The Special Issue will provide a platform for researchers and practitioners to exchange their ideas and findings, discuss the latest developments, and explore future directions in the field of intelligent maintenance and health management in ocean engineering. Topics of interest include, but are not limited to:

  • Fault diagnosis;
  • Online monitoring technology;
  • Fault prognosis and health management (PHM);
  • Remaining useful life prediction;
  • Maintenance optimization;
  • Predictive maintenance schemes;
  • Condition-based maintenance schemes;
  • Uncertainty quantification and management in PHM;
  • Reliability assessment;
  • Reliability prediction;
  • Risk analysis;
  • Signals processing approaches;
  • Condition state recognition.

This study deals with a method for anomaly detection in seawater temperature data using machine learning methods with oversampling techniques. Data were acquired from 2017 to 2023 using a Conductivity–Temperature–Depth (CTD) system in the Pacific Ocean, Indian Ocean, and Sea of Korea. The seawater temperature data consist of 1414 profiles including 1218 normal and 196 abnormal profiles. This dataset has an imbalance problem in which the amount of abnormal data is insufficient compared to that of normal data. Therefore, we generated abnormal data with oversampling techniques using duplication, uniform random variable, Synthetic Minority Oversampling Technique (SMOTE), and autoencoder (AE) techniques for the balance of data class, and trained Interquartile Range (IQR)-based, one-class support vector machine (OCSVM), and Multi-Layer Perceptron (MLP) models with a balanced dataset for anomaly detection. In the experimental results, the F1 score of the MLP showed the best performance at 0.882 in the combination of learning data, consisting of 30% of the minor data generated by SMOTE. This result is a 71.4%-point improvement over the F1 score of the IQR-based model, which is the baseline of this study, and is 1.3%-point better than the best-performing model among the models without oversampling data.
