Motion Response Characteristics of Small Fishing Vessels of Different Sizes among Regular Waves

DongHyup Youn, LeeChan Choi, JungHwi Kim

J. Ocean Eng. Technol.. 2023;37(1):1-7.

The motion of small fishing vessels is significantly affected by small waves, leading to accidents, such as capsizing or sinking. This paper presents the results of two types of basin tests. The first test analyzed the characteristics of roll and pitch motions among regular waves with the same wave steepness...

Numerical Analysis for Motion Response of Modular Floating Island in Waves

Hyo-Jin Park, Jeong-Seok Kim, Bo Woo Nam

J. Ocean Eng. Technol.. 2023;37(1):8-19.

In recent years, modular-type floating islands have been considered as a promising option for future ocean space utilization. A modular floating island consists of a number of standardized pontoon-type modules and connectors between them. In this study, the motion responses of a modular floating island in waves was investigated based...

A Study on Design Variables for Increasing the Breaking Strength of Synthetic Fiber Chain

Kyeongsoo Kim, Seonjin Kim, Hyunwoo Cho, Dokyoun Kim, Yongjun Kang, et al.

J. Ocean Eng. Technol.. 2003;37(1):31-37.

In this study, a fiber chain was developed to replace a steel chain using high-modulus polyethylene DM20. The pick count, wrapping count, and inner length were selected as the main design variables of the fiber chain and were analyzed to increase the breaking strength. Orthogonal array experiments were conducted, and...

Tracking of ARPA Radar Signals Based on UK–PDAF and Fusion with AIS Data

Chan Woo Han, Sung Wook Lee, Eun Seok Jin

J. Ocean Eng. Technol.. 2023;37(1):38-48.

To maintain the existing systems of ships and introduce autonomous operation technology, it is necessary to improve situational awareness through the sensor fusion of the automatic identification system (AIS) and automatic radar plotting aid (ARPA), which are installed sensors. This study proposes an algorithm for determining whether AIS and ARPA...
