Numerical Investigation of Motion Response of the Tanker at Varying Vertical Center of Gravities

Van Thuan Mai, Thi Loan Mai, Hyeon Kyu Yoon

J. Ocean Eng. Technol.. 2024;38(1):1-9.

The vertical center of gravity (VCG) has a significant impact on the roll motion response of a surface ship, particularly oil tankers based on the oil level in the tanker after discharging oil at several stations or positional changes, such as changes in the superstructure and deck structure. This study...

Crabbing Motion Testing of Waterjet-Powered Ships Using Stern Thrusters

Joopil Lee, Seung-Ho Ham

J. Ocean Eng. Technol.. 2024;38(1):10-17.

This study assessed the potential for crabbing motion in waterjet ships by exclusively employing stern thrusters. The theoretical considerations were validated through practical sea trials on the naval vessel PKG (Patrol Killer Guided missile) equipped with three stern thrusters. The control forces were calculated using the force equilibrium equation. The...
