Daewoo Shipbuilding led the development of an LNG HP Pump to complete a durability test

Recently, the LNG marine high-pressure pump jointly developed by South Korea’s Daewoo Shipbuilding and Hyupsung Metallize has completed the durability test, successfully realizing the localization of this LNG marine core equipment.

The LNG marine high-pressure pump is the core equipment that provides fuel for the diesel-natural gas dual-fuel ME-GI engine in order to meet the requirements of the new international marine environmental protection regulations. Up to now, all Korean shipbuilding companies need to import this equipment from the United States, France, and other places. Daewoo Shipbuilding said that the localization of this product not only helps to shorten the delivery cycle of ships but also greatly helps to reduce costs.

It is reported that this test has passed the two-month, 24-hour continuous operation test based on the failure-free life test, which ended the verification of the durability of the main components of the equipment and the safety of long-term equipment operation. The test ensures that the equipment can complete 4000 hours of continuous operation like the existing overseas imported products.

The success of this test is the first achievement achieved by a Korean shipbuilding company in cooperation with a small and medium-sized cooperative company to develop and manufacture LNG marine core equipment. During this period, Daewoo Shipbuilding provided special LNG-related technologies, as well as the industry’s first LNG-related comprehensive test facility built in 2015 – the test equipment of the Energy System Experiment Center, Korea Institute of Machinery (KIMM), Korea Shipbuilding and Marine Equipment Research Research Institute (KOMERI) established test procedures and conducted durability test evaluations.

An official of Daewoo Shipbuilding said: “The success of this test is win-win cooperation between research institutions and large and small and medium-sized enterprises. In the future, the company will further improve market technology and price competitiveness through the localization of core marine equipment. Contribute to single competitiveness.”

In addition, in order to realize the certification of LNG marine high-pressure pump technology, in addition to durability tests, Daewoo Shipbuilding is also cooperating with international classification societies such as the Korea Register of Shipping (KR) and DNV to promote the type approval certification process.

Daewoo Shipbuilding said, “For more than 20 years, we have been focusing on LNG research and development. Through the empirical research and development of the Energy System Experiment Center, we have achieved LNG-related technological competitiveness that is synchronized with the world. At the same time, we will make every effort to realize the localization of LNG marine equipment.” (Wang Chu)

大宇造船牵头研制LNG船用高压泵完成耐久性试验

近日，韩国大宇造船与韩国Hyupsung Metallize公司联合开发研制的LNG船用高压泵完成耐久性试验，成功实现了这一LNG船用核心设备的国产化。

LNG船用高压泵是为满足国际海事环保新规要求，为柴油-天然气双燃料ME-GI发动机提供燃料的核心设备。截止目前，韩国造船企业全部需要从美国、法国等地进口这一设备。大宇造船表示，该产品的国产化不仅有助于缩短船舶交付周期，对降低成本也有很大帮助。

据悉，此次试验通过2个月24小时连续运行测试为主的无故障寿命测试，结束了对于该设备主要零部件的耐久性和长时间设备运行的安全性验证。通过试验，确保该设备可与现有海外进口产品一样完成4000小时连续运行。

此次试验成功是韩国造船企业首次联合中小合作公司开发制作LNG船用核心设备取得的成果，有助于带动本国中小企业共同成长，增强韩国LNG相关技术能力，因此具有重要意义。在此期间，大宇造船提供了特殊的LNG相关技术，以及2015年建成的业界首个LNG相关综合试验设施——能源系统实验中心的试验设备，韩国机械研究院(KIMM)、韩国造船海洋设备研究院(KOMERI) 则建立了试验程序并进行了耐久性试验评价。

大宇造船相关人士表示：“此次试验成功是研究机构和大、中小企业通过合作共赢实现的举措。今后，公司将通过船用核心设备国产化，进一步提高市场技术及价格竞争力，为提高接单竞争力做出贡献。”

此外，大宇造船为了实现LNG船用高压泵技术的认证，除了耐久性试验外，还与韩国船级社(KR)、DNV等国际船级社正在合作推进型式认可认证程序。

大宇造船表示：“20多年来，我们一直聚焦LNG领域进行研发。通过能源系统实验中心的实证研究开发，我们已经拥有了与世界同步的LNG相关技术竞争力。在持续开发多种环保以及与数字技术相结合的产品的同时，我们还将竭尽全力实现LNG船用设备的国产化。”（王楚）
