Ship Motion-Based Prediction of Damage Locations Using Bidirectional Long Short-Term Memory

Hye-young Son, Gi-yong Kim, Hee-jin Kang, Jin Choi, Dong-kon Lee, et al.

J. Ocean Eng. Technol.. 2022;36(5):295-302.

The initial response to a marine accident can play a key role to minimize the accident. Therefore, various decision support systems have been developed using sensors, simulations, and active response equipment. In this study, we developed an algorithm to predict damage locations using ship motion data with bidirectional long short-term...

Computational Investigation of Seakeeping Performance of a Surfaced Submarine in Regular Waves

Doojin Jung, Sanghyun Kim

J. Ocean Eng. Technol.. 2022;36(5):303-312.

A submarine is optimized to operate below the water surface because it spends most of its time in a submerged condition. However, the performance in free surface conditions is also important because it is unavoidable for port departure and arrival. Generally, potential flow theory is used for seakeeping analysis of...

Analysis of Hydraulic Characteristics According to the Cross-Section Changes in Submerged Rigid Vegetation

Jeongheum Lee, Yeon-Myeong Jeong, Jun-Seok Kim, Dong-Soo Hur

J. Ocean Eng. Technol.. 2022;36(5):326-339.

Recently, not only Korea but also the world has been suffering from problems related to coastal erosion. The hard defense method has been primarily used as a countermeasure against erosion. However, this method is expensive and has environmental implications. Hence, interest in other alternative methods, such as the eco-friendly vegetation...

Underwater Navigation of AUVs Using Uncorrelated Measurement Error Model of USBL

Pan-Mook Lee, Jin-Yeong Park, Hyuk Baek, Sea-Moon Kim, Bong-Huan Jun, et al.

J. Ocean Eng. Technol.. 2022;36(5):340-352.

This article presents a modeling method for the uncorrelated measurement error of the ultra-short baseline (USBL) acoustic positioning system for aiding navigation of underwater vehicles. The Mahalanobis distance (MD) and principal component analysis are applied to decorrelate the errors of USBL measurements, which are correlated in the x- and y-directions...
