Title: Jin Ho Choi: Innovations in Liquefied-Gas-Fuel Ship Systems.

Introduction

Jin Ho Choi is an inventor based in Incheon, South Korea, whose work focuses on technologies for liquefied-gas-fuel ships and shipboard gas-handling systems. He is associated with Hanwha Ocean Co., Ltd. His listed portfolio includes 2 patents addressing fuel efficiency and refrigerant charging for maritime applications.

Latest Patents

Choi’s listed inventions include “Power-saving liquefied-gas-fuel ship and method for processing boil-off gas for liquefied-gas-fuel ship.” The system uses liquefied gas or boil-off gas to fuel a ship’s engine. It compresses excess boil-off gas and cools it through a heat exchanger, while a refrigerant circulation system and cold-heat recovery device help reduce the refrigerant’s temperature. The design aims to make use of available cold energy and support more efficient ship operations.

His other listed invention, “Refrigerant charging system for reliquefaction system for ship,” concerns charging a ship’s reliquefaction system with refrigerant. A buffer tank supplies nitrogen to the refrigerant circulation line, either through a booster compressor or, during initial charging, through a load-up line that uses the pressure difference between the tank and the circulation line. The system is designed to support refrigerant charging when the reliquefaction system is not operating.

Career Highlights

Choi’s listed patent work addresses practical challenges in maritime energy systems, including the handling of boil-off gas, recovery of cold energy, and preparation of shipboard reliquefaction equipment. His association with Hanwha Ocean connects this work to shipbuilding and marine engineering.
