China-built VLCC featuring green technologies delivered in Dalian_我的网站

A |     　　讯 近日，市场监管总局（国家标准委）批准发布《车用压缩天然气》（GB 18047—2026）强制性国家标准，将自2027年8月1日起实施。　　本次标准修订旨在提升产品质量、保障使用安全、促进贸易公平。一是技术指标持续健全，新增甲烷值和互换性要求，明确车用压缩天然气的甲烷值应不小于65，与欧洲标准的要求保持一致，当甲烷值小于70时，加气站须在经营场所显著位置向社会公示具体数值。    (ECNS) -- A new-generation very large crude carrier (VLCC), independently developed and built by China, was delivered in Dalian, Liaoning Province, on Monday.    Named Front Fraser, the 307,000-metric-ton crude oil tanker was built by Dalian Shipbuilding Industry Co., Ltd. (DSIC) and China Shipbuilding Trading Co., Ltd. for Norwegian shipping company SEATANKERS.    The vessel measures about 333 meters in length, 60 meters in width and 30 meters in depth, with a deck area of more than 18,000 square meters.    Its total coated surface area exceeds 540,000 square meters, equivalent to about 76 standard football fields.    Designed for strong adaptability to different ports and waterways, the tanker can carry more than 2 million barrels of crude oil at a design draft of 20.5 meters and is capable of navigating through the Strait of Malacca.    Equipped with an exhaust gas cleaning system, the vessel is expected to save about 35 million yuan ($4.9 million) in fuel costs annually.    Its nitrogen oxide emissions meet Tier III standards, the strictest requirements under relevant international conventions, while the vessel also complies with Phase III of the Energy Efficiency Design Index (EEDI).    Wang Rongtao, project manager at DSIC, said the vessel successfully passed all sea trials on its first attempt and was delivered 43 days ahead of schedule, with several key technical indicators exceeding contractual requirements.    (By Intern Liu Shuangjing, Zhang Dongfang)                    。同一地区的车用压缩天然气应能互换使用，确保不同气源的天然气在切换使用时不影响发动机性能和安全性。二是试验方法全面升级，新增或调整了高位发热量、总硫、硫化氢、二氧化碳、氧气、水露点、水含量等项目的检测方法，其中甲烷值计算方法新增丙烷爆震指数法（PKI-MN法）作为仲裁试验方法，与国际标准接轨。三是取样与判定规则不断完善，新增“取样”独立章节，取样点设在车用压缩天然气交接点。判定规则明确检验结果达到全部质量要求视为合格，不符合时应复测。版权申明：凡注有“”或电头为“”的稿件，均为独家版权所有，未经许可不得转载或镜像；授权转载必须注明来源为“”，并保留“”的电头。    。
