Striving for a Winning Start and Achieving Excellence in the New Year. Recently, several steel companies have shared exciting news about their product development and applications. The details are summarized as follows—

Baosteel co.

近日，塔里木盆地传来令人振奋的消息。宝钢股份自主研发的BG155V高强高韧高气密性套管，作为完井管柱，在该盆地某特深复杂探井中成功入井并到达指定位置。此探井完钻垂直井深超过10900米，是目前世界第二、亚洲第一深直井，这一成果标志着宝钢石油套管达到世界领先水平，也创造了国产套管下井深度的新纪录。

It is estimated that the strata deeper than 10,000 meters in the Tarim Basin are rich in oil and gas resources. However, due to limitations such as oil casing and drilling equipment, these resources have not been effectively explored and developed. As China's first risk exploration well with a completed drilling depth exceeding 10,000 meters, this well carries the significant mission of exploring oil and gas from entirely new strata at such depths. The ultra-deep geological structures are extremely complex; beyond 10,000 meters, the bottom hole temperature has already exceeded 200°C, and at depths nearing 10,000 meters, it approaches 300°C, surpassing the temperature and pressure limits of most downhole materials, thereby imposing extremely high demands on the performance and reliability of the oil casing.

宝钢股份充分发挥在石油套管制造与产品研发领域的优势，从项目伊始便积极组织产销研团队，全程深度参与钻井方案论证、井身结构和管柱结构设计以及配套选材工作，并针对性地设计开发了专用套管。钢管条钢事业部作为石油套管的设计制造主体，精心制定了专用制造工艺流程和严格的质量保证措施，前期通过科学合理的性能评价试验，充分保证套管产品性能和质量能够完全适应井下恶劣工况对材料的严苛要求。

At the same time, a specialized casing running operation procedure was developed, and skilled service personnel were dispatched to the well site to provide round-the-clock support. Despite numerous challenges such as unusually low temperatures and high operational difficulties, the team persevered and ultimately ensured the successful placement of the casing into the well.

Looking ahead, Baosteel will continue to actively fulfill its responsibilities as a central enterprise, leveraging its strengths in research and development as well as manufacturing. It aims to develop more high-performance oil casing products with excellent performance and reliable quality, tailored to specific needs. These efforts will provide comprehensive solutions for deep and ultra-deep oil and gas exploration and development, contributing more to ensuring national energy security.

Shougang Jingtang

Recently, the ultra-high-strength marine steel produced by Shougang Jingtang was used in the project of a fixed jib crane ship with a capacity of [ ] tons by Drydocks World Dubai. Upon delivery, the vessel will become the largest crane ship of its type in the Persian Gulf and Africa region, significantly enhancing heavy lifting capabilities in the area. This also marks a solid step forward for Shougang Jingtang in the field of marine engineering equipment.

效果图据悉，该起重机为迪拜干船坞世界公司5000吨固定臂架式起重船项目的起重设备，主钩5000吨吊高120米，副钩600吨吊高180米，配备锚泊定位系统，适用于海上模块安装、海上风电安装、桥梁吊装以及大型工程船舶总装等多种工程项目。本次供货采用EVI服务模式，根据客户需求，首钢京唐与技术研究院通过技术创新，为客户提供整体解决方案，减轻海洋工程结构重量，同时又增加结构整体安全性。

The ultra-high-strength marine steel produced this time features significant thickness and wide plate dimensions, overcoming the technical challenges of balancing strength and toughness and ensuring internal quality in high-strength, thick steel plates. With a maximum thickness of [insert value], it marks a new breakthrough in the supply thickness of ultra-high-strength marine steel.

期间，首钢京唐制造部、中厚板事业部、钢轧作业部、质检监督部、销售管理部、技术中心与首钢技术研究院、股份营销中心等单位高效协同，针对该订单规格尺寸，优化铸坯设计和轧制规程，同时根据产品厚规格超宽幅的特点，优化轧制和热处理工艺，保证产品的强韧性能，最终成功生产出尺寸、性能、表面质量等均满足用户和标准要求的产品，保障了从合同组织到产品交付的全流程优质服务。

The rapid delivery of this contract demonstrates Shougang Jingtang's ability to quickly respond to user demands and its capabilities in intelligent manufacturing and fast, precise delivery. Currently, Shougang Jingtang's medium and heavy plates have been certified by nine classification societies, including [list of societies], with the highest strength grade, quality level reaching [specific grade], maximum thickness of [specific] millimeters, and delivery conditions covering controlled rolling, normalizing rolling, normalizing, and quenching and tempering.

近年来，首钢中厚板船板应用于亚洲最大的深海智能网箱"经海号"、亚洲首制海上风电运维母船"至臻"和"至诚"号、亚洲最大的重型自航绞吸船"天鲲号"等重点工程项目。此单合同是中厚板产线顺利通过美国船级社海工钢船规认证后的又一重大突破，拓宽了首钢京唐海工钢产品的接单能力，对改善宽厚板的品种结构、开拓新的利润增长点具有重要意义。

Nanjing iron and steel

Not long ago, China's first large-scale floating liquefied natural gas (LNG) facility was launched in Nantong, marking the near completion of the country's independently built new-type offshore floating LNG facility with the largest tonnage and gas storage capacity. Nanjing Iron and Steel supplied a significant proportion of the carbon-manganese low-temperature steel used. This milestone achievement not only demonstrates China's strong capabilities in the field of marine engineering equipment manufacturing but also highlights Nanjing Iron and Steel's outstanding contributions to the research, development, and production of new materials.

该装置是专为国外某知名油气巨头集团量身打造，其垂线间长达350米，型宽60米，型深35米，建成后将部署于刚果(布)离岸约50公里、水深约30米至50米的海域。满负荷状态下，每天可从附近气田接收约3.8亿立方英尺(约合1076万立方米)天然气，堪称船舶海工行业"皇冠上的新明珠"。

The Floating Liquefied Natural Gas (FLNG) vessel, as a floating LNG processing platform, is capable of directly liquefying and storing extracted natural gas in offshore areas far from land. It boasts advantages such as a short development cycle, low investment costs, high production capacity utilization, and strong flexibility, making it one of the most complex, costly, and high-value-added products in offshore engineering equipment. Among these, Nanjing Iron and Steel has supplied a significant amount of high-quality carbon-manganese low-temperature steel plates, providing solid material support for the construction of these vessels.

In response to the extremely high requirements for low-temperature resistance and safety performance of the steel plates for this floating liquefied natural gas facility, Nangang Steel has strictly controlled every step from the selection of raw materials to the production process, ensuring that all steel plates leaving the factory meet premium standards. It is this relentless pursuit of quality that has enabled Nangang Steel to efficiently and high-qualityly complete the supply task, providing strong support for the smooth construction of the facility.

作为在绿色环保能源领域深耕多年的企业，南钢在碳锰低温钢的研发和生产上取得了显著成果。南钢在国内率先攻克碳锰低温钢的生产技术瓶颈，填补了市场空白，极大程度上改善了碳锰低温钢长期依赖进口的现状，实现国产代替进口。

Currently, Nanjing Iron and Steel (Nangang) has obtained certifications from several classification societies. These include the China Classification Society, American Bureau of Shipping, Bureau Veritas, DNV (Det Norske Veritas), and Germanischer Lloyd. Nangang boasts extensive experience and broad applications in the shipbuilding and offshore engineering sectors. Its key competitive products include shipbuilding steel, and the company has established strong partnerships with renowned domestic and international shipbuilding and offshore engineering enterprises, covering a full range of vessels such as container ships, roll-on/roll-off ships, luxury cruise liners, and wind turbine installation vessels.

The successful undocking of this large floating liquefied natural gas (LNG) unit not only significantly enhances Nanjing Iron and Steel (NISCO)'s recognition in the high-end shipbuilding market but also serves as a vivid demonstration of NISCO's active response to the national call for green development and its commitment to promoting high-quality industry growth. It further marks the strengthening of China's position and influence in the field of marine engineering equipment manufacturing.

In the future, Nangang will continue to increase R&D investment in the green and environmental energy sector, continuously improve product quality and technical capabilities, and contribute more to the green transformation and high-quality development of the global shipping industry.
