Impact of Hull Condition and Propeller Surface Maintenance on Fuel Efficiency of Ocean-Going Vessels

Tien Anh Tran, Do Kyun Kim

J. Ocean Eng. Technol.. 2023;37(5):181-189.

The fuel consumption of marine diesel engines holds paramount importance in contemporary maritime transportation and shapes energy efficiency strategies of ocean-going vessels. Nonetheless, a noticeable gap in knowledge prevails concerning the influence of ship hull conditions and propeller roughness on fuel consumption. This study bridges this gap by utilizing artificial...

A Study for Digital Transformation Based on Collaboration Master Plan for Shipbuilding & Marine Engineering Industry

Seung-Uk So, Myeong-Ki Han, Young-Hun Kim, Jun-Soo Park

J. Ocean Eng. Technol.. 2023;37(5):190-197.

In the shipbuilding and marine industry, digital transformation activities are promoted primarily by large shipyards. However, bottlenecks are observed across value chains, and digital transformation effects are reducing because of the cost and technical challenges encountered by supplies. In this study, we proposed a win-win cooperation model for large, small,...

Estimating Hydrodynamic Coefficients of Real Ships Using AIS Data and Support Vector Regression

Hoang Thien Vu, Jongyeol Park, Hyeon Kyu Yoon

J. Ocean Eng. Technol.. 2023;37(5):198-204.

In response to the complexity and time demands of conventional methods for estimating the hydrodynamic coefficients, this study aims to revolutionize ship maneuvering analysis by utilizing automatic identification system (AIS) data and the Support Vector Regression (SVR) algorithm. The AIS data were collected and processed to remove outliers and impute...
