HJSC developed eco-friendly LNG bunkering of 7,500㎥ class




- Development of LNG bunkering vessel of 7,500㎥ class following successful construction of LNG bunkering vessel of 5,100㎥ class for the first time in the world. 
- ‘Spurring’ development of eco-friendly technologies including LNG DF, methanol-fuelled vessel, hydrogen-powered vessel and vessels discharging no ballast water. 


- The world’s first LNG Bunkering Vessel ENGIE ZEEBRUGGE constructed by HJSC


HJSC Shipbuilding(CEO Yu Sang-cheol) is fully committed to secure the core technologies for dominating eco-vessel market after completing the development of the new LNG bunkering vessel model. 


Fulled by the support from Ministry of Trade, Industry and Energy for the strong medium shipbuilder innovation and advancement project, HJSC successfully developed the LNG bunkering vessel model of 7,500㎥ class, the vessel supplying LNG on the sea and acquired the Approval in Principle on the master design of LNG bunkering vessel. The certification agency is the Lloyd’s Register of Ships(LR), the largest register organization in the world with over 200 years’ history and prestige. 


The LNG bunkering vessel of 7,500㎥ class developed by HJSC is the new model following the LNG bunkering vessel of 5,100㎥ class ordered by NYK, Japan in 2014. The order was the hot issue because it was the first order of universal LNG bunkering vessel in the world at that time. 


The LNG-powered vessel generally receives LNG from the inland LNG tank. The LNG-powered vessel can directly receive LNG on the sea using the LNG bunkering vessel without the need for docking. It’s the reason why the LNG bunkering vessel is called ‘floating gas station on the sea’. 


The LNG bunkering vessel developed by HJSC adopted the ship-to-ship method which is considered as the most effective bunkering vessel. It can fuel LNG of 7,500㎥ at once using two independent pressure-type LNG tanks certified by International Maritime Organization. Controllability and sailing efficiency are also secured by dual fuel system(LNG/MGO Dual fuel). 


In particular, HJSC developed the bunkering vessel ‘without ballast water’ enabling a vessel to sail without drawing or discharging ballast water in order to prevent marine ecosystem to be disturbed by ballast water used by a vessel (sea water filling a tank to keep the center of gravity of a vessel). The vessel without ballast water is considered as the state-of-art vessel because it doesn’t require the separate treatment unit for ballast water and saves shipbuilding and operating costs. 


HJSC has been enhancing its reliability by accumulating the eco-friendly shipbuilding technologies for the next generation in the market including Methanol Ready applied to the container vessel of 5,500TEU class(vessel which can use methanol as fuel in the future) which was already developed and LNG dual fuel technology applied to the container vessel of 7,700TEU class.  Through such endeavor, HJSC made the great achievement as receiving the order for 3 methanol-powered container vessels of 9,000TEU class from HMM last Feb. 


For development of hydrogen-powered vessel, HJSC is devoting on development of technologies together with Hydrogen Ship Technology Center of Busan National University. Hydrogen-powered vessel is drawing substantial attention as the green ship of the next generation enabling to realize the carbon neutrality because it never discharges carbon dioxide.  


An official of HJSC said, “we expect the rapid expansion of the eco-vessel market using eco-energy as the main fuel due to carbon emission curbs by International Maritime Organization. HJSC will secure the super gap competitiveness in the market by constructing the eco-vessels as well as developing the technologies which can realize zero carbon.”
