Hyundai High Efficient Gas Supply System get AIP from DNV & LR

Hyundai Heavy Industries Group has successfully developed a fuel supply system for LNG-powered ships that reduces fuel consumption and carbon emissions.

On June 23, Korea Shipbuilding Marine and Hyundai Heavy Industries, the shipbuilding holding company of Hyundai Heavy Industries Group, said that the new generation of high-efficiency LNG fuel supply system Hi-eGAS (Hyundai High Efficient Gas Supply System) developed by it has won the Approval in Principle (AIP) certificate issued by Det Norske Veritas (DNV) and Lloyd’s Register of Shipping (LR).

The fuel supply system is a key technology for LNG-powered ships, and Hi-eGAS is characterized by the ability to recycle the waste heat during the fuel supply process for LNG-powered ships. Compared with the Hi-GAS independently developed by Hyundai Heavy Industries, fuel consumption and carbon emissions can be reduced by 1.5%, thus improving fuel efficiency and reducing fuel operating costs.

LNG-powered ships need to heat and gasify LNG at -163oC and use it as fuel. In this process, there are disadvantages of increasing fuel consumption and carbon emissions. However, Hi-eGAS can use the waste heat of marine engines to heat LNG fuel. This reduces unnecessary fuel consumption, which reduces both carbon emissions and fuel costs.

In addition, Korea Shipbuilding & Marine Engineering and Hyundai Heavy Industries have jointly developed the heat exchanger, the core component of Hi-eGAS, with Korean ship supporting companies, which greatly reduces the risk of ice formation in the LNG fuel supply system.

Last year, Korea Shipbuilding & Marine Corporation, in cooperation with the Korea Institute of Machinery (KIMM), conducted an empirical sailing test of the Hi-eGAS using actual LNG fuel under the same conditions as large LNG-powered ships, and its performance and stability were certified.

An official from Hyundai Heavy Industries Group said: “High-efficiency and low-carbon ships are products that are in line with the global trend of achieving carbon neutrality. While developing a new generation of future ships, we also plan to speed up the upgrading of environmentally friendly ship technologies.” (Wang Chu)

现代重工集团新一代高效LNG燃料供应系统获两家船级社认证

现代重工集团成功开发出了可减少燃料消耗和碳排放的LNG动力船燃料供应系统。

6月23日，现代重工集团造船控股公司韩国造船海洋与现代重工表示，其开发的新一代高效LNG燃料供应系统Hi-eGAS(Hyundai High Efficient Gas Supply System)获得了挪威船级社（DNV）和英国劳氏船级社（LR）颁发的原则性认可(AIP)证书。

燃料供应系统是LNG动力船的一项关键技术，而Hi-eGAS的特点是能够回收利用LNG动力船燃料供应过程中废弃的热量。与现代重工此前自主研发的Hi-GAS相比，燃料消耗和碳排放量可减少1.5%，因此可提高燃料使用效率，降低燃料运行成本。

LNG动力船需要将零下163摄氏度的LNG加热气化并作为燃料使用，在此过程中存在增加燃料消耗和碳排放的缺点，但Hi-eGAS可通过船用发动机的废弃热量对LNG燃料进行加热，由此减少了不必要的燃料消耗，既可减少碳排放量，还可节约燃料费用。

此外，韩国造船海洋和现代重工还与韩国船舶配套企业共同开发了Hi-eGAS的核心部件热交换器，大幅降低了LNG燃料供应系统内发生结冰现象的危险。

去年，韩国造船海洋与韩国机械研究院（KIMM）合作，在与大型LNG动力船相同的条件下，对Hi-eGAS采用实际LNG燃料进行了实证航行测试，其性能和稳定性得到了认证。

现代重工集团相关人士表示：“高效低碳船舶是符合实现碳中和全球大势的产品。我们在开发新一代未来船舶的同时，还计划加快提升环保船舶技术的速度。”（王楚）
