Hudong Zhonghua independently developed the first domestic LNGC pump tower integrated lifting platform

A few days ago, the first set of LNG ship pump tower integrated lifting platform independently developed by China Shipbuilding Corporation Hudong Zhonghua was successfully lifted in the No. 2 cargo hold of H1831A ship and passed the joint acceptance team composed of the shipowner, ship inspection, and GTT company. This marks that the installation platform of the key process in the special area of ​​the company’s LNG tanker cargo tank has been officially applied to the actual ship, and a breakthrough has been achieved in key process technology. In this project, the company has completely independent intellectual property rights, has applied for two national invention patents, and has been authorized.

The construction of the enclosure system in the pump tower area of ​​the LNGC is the last link in the construction of the entire cargo tank, and the construction efficiency directly affects the construction period of the LNGC. The pump tower of the 174,000cbm LNGC is as high as 30 meters. The traditional construction method requires steel pipe scaffolding to be erected along with the pump tower from the bottom to the top to carry out the construction of the enclosure system in the liquid dome area. It is very easy to cause damage, the construction is difficult, and the safety risk is high. Therefore, the development of a pump tower construction platform with safe and reliable performance, efficient and convenient construction is the key to improving quality and efficiency.

Hudong Zhonghua Technology Research Institute and the Second General Assembly Department carried out the grass-roots party organization “helping and promoting” joint construction activities, established a “four innovations” joint technical research team with party members and youth league members as the core, and carried out the installation platform tooling for the enclosure system R&D. The young talents of the “Four Creation” team carried out brainstorming and developed a “hui”-shaped structure platform, which can be freely disassembled, has strong versatility and a high degree of standardization, and improved the overall efficiency of the main LNG ship products for Hudong Zhonghua core. Contribute new solutions.

During the implementation of the project, the company’s LNG project team gave full play to its safety leadership, carried out project safety risk analysis conscientiously, and organized the LNG Institute, Production Management Department, Health Insurance Department, Security Department, Dongding Company, and the shipowner’s on-site construction supervision team to work together. Collaborate to formulate a project implementation safety emergency management and control plan, and ensure the successful and safe lifting of the first platform, fully demonstrating Hudong Zhonghua‘s strong strength in collaborative innovation and safety culture construction.

沪东中华自主研制国内首套LNG船泵塔一体化升降平台成功应用

日前,由中国船舶集团沪东中华自主研制的首套LNG船泵塔一体化升降平台在H1831A船2号货舱顺利升顶,通过得船东、船检和GTT公司组成的联合验收组认可。这标志着,公司LNG船液货舱特殊区域关键工序的安装平台,正式实船应用,在关键工艺技术上实现突破。公司在该项目上,拥有完全自主知识产权,已申请国家发明专利两项并获授权。

LNG船液穹泵塔区域的围护系统施工是整个液货舱建造的最后环节,施工效率直接影响LNG船建造周期。17.4万方LNG船泵塔高达30米,传统的施工方法需要沿着泵塔自下而上搭设钢管脚手架来进行液穹区域围护系统的施工,因为泵塔材质特殊,搭设脚手架和施工过程中极易造成破损,施工难度大、安全风险高。因此,研制一款性能安全可靠、施工高效便捷的泵塔施工平台,是提质增效的关键。

沪东中华工艺技术研究所和总装二部开展基层党组织“帮学促”共建活动,成立了以党员、团员青年为核心的“四创”联合技术攻关团队,开展围护系统安装平台工装研发。“四创”团队的青年才俊开展头脑风暴,研发出一种“回”字形结构平台,可自由拆卸、通用性强、标准化程度高,为沪东中华核心主建LNG船产品的整体效率提升贡献新方案。

项目实施过程中,公司LNG项目组充分发挥安全领导力,认真开展项目安全风险分析,组织LNG所、生管部、生保部、安保部、东鼎公司、船东现场监造组等相关单位通力协作,编制项目实施安全应急管控预案,并确保首制平台成功安全升顶,充分展现沪东中华在协同创新和安全文化建设方面的强大实力。
