2010年4月5日16时，越南头顿市STRATEGIC MARINE（V）船厂内，随着一声清脆的信号枪响，总长143米、自重6800吨的"CABALLO MAYA"号潜水支持船在68组特种气囊的托举下，以1分钟完美弧线滑入大海。这场由青岛永泰永安顺下水工程公司主导的全球首例大坡度简易平台气囊下水工程，不仅刷新了越南造船史纪录，更标志着中国船舶辅助技术正式叩开国际高端市场大门。

一、技术攻坚：在80米高空书写"中国方案"

作为澳大利亚STRATEGIC MARINE集团在越南的海工船投资项目，该船建造平台采用非常规设计：由间距6米的水泥桩与碎石填充层构成，末端悬空高度达82米，坡度超过1:10。这种结构导致传统滑道下水法存在船体断裂风险，而液压平板车运输成本高达千万美元。

青岛永泰技术团队经三维模拟测算，创新提出"分级顶升-动态移位-气囊缓冲"复合方案：

  1. 定制直径2.5米、承载力300吨的加强型气囊矩阵

  2. 开发多级液压同步顶升系统（精度±2mm）

  3. 设计自适应坡度调节装置

  4. 建立实时应力监测网络（200个传感器）

二、战场实录：72小时极限操作

  • 3月28日：工程师团队携激光扫描仪、全站仪等设备抵越，完成平台三维建模

  • 4月1日：制定"五阶段"下水计划，确定******潮汐窗口（落潮时段流速0.8节）

  • 4月3日：启动顶升作业，12组千斤顶同步作业，历时8小时完成船体脱离

  • 4月4日：采用"步进式"移位技术，以每小时5米速度完成40米横向平移

  • 4月5日：15:30启动最终检查，16:00割断牵引缆，船体以0.3m/s匀速入水

关键数据：

  • 顶升高度：3.2米（创亚洲纪录）

  • 移位精度：横向偏差＜15mm

  • 气囊完好率：100%（68组无一破损）

  • 作业周期：较传统方案缩短60%

三、国际认可：从技术输出到标准制定

现场观摩的越南海事局副局长阮文雄评价："这是东南亚造船史上最具创新性的解决方案。"STRATEGIC MARINE集团随即签署价值280万美元的续约合同，并指定永泰技术为集团全球标准。

此次突破具有三重战略意义：

  1. 技术输出：首次实现大型海工船气囊下水技术标准化

  2. 成本优势：较传统方案降低42%成本

  3. 安全革新：建立高悬空平台作业安全规范（获DNV认证）

四、行业影响：中国技术开启全球化新篇

据国际船舶网统计，2010-2015年间，气囊下水技术已应用于全球17个国家38个项目，累计节约建设成本超5亿美元。青岛永泰借此契机，主导制定ISO/TC8《船舶辅助设备》国际标准，推动中国技术从"跟跑"转向"领跑"。

正如项目总指挥于新波所言："当68组气囊同时爆发的瞬间，我们托起的不仅是6800吨钢铁，更是中国船舶工业走向世界的信心。"这场发生在越南海域的技术革命，正书写着"中国制造"向"中国创造"跨越的新篇章。

At precisely 16:00 on April 5, 2010, the 6,800-tonne “CABALLO MAYA” dive support vessel slid smoothly into the waters off Vung Tau, Vietnam, marking the world’s first successful airbag launch of a large offshore vessel from an 82-meter-high inclined platform. This engineering feat by Qingdao Eversafe Marine Engineering Co. Ltd not only set a Vietnamese shipbuilding record but also demonstrated China’s technological leadership in global marine auxiliary systems.

I. Technical Breakthrough: Conquering the 82m Vertical Challenge

As a flagship project of Australian shipbuilding giant STRATEGIC MARINE, the 143m-long vessel posed unprecedented launch challenges:

  • Platform Design: Built on 6m-spaced concrete piles with gravel infill, ending in an 82m vertical drop

  • Traditional Limitations: Conventional slipway launching risked hull fracture; hydraulic transporter costs exceeded USD 10M

Qingdao Evergreen’s Solution:

  1. Custom Airbag Matrix: 68 reinforced airbags (Ø2.5m, 300T/unit capacity)

  2. Multi-Stage Synchronized Lifting: Hydraulic system with ±2mm precision control

  3. Adaptive Slope Compensation: Dynamic pressure regulation for 1:10 gradient

  4. Real-Time Monitoring: 200-sensor network tracking structural stress

II. 72-Hour Operation Timeline

  • Mar 28: Engineering team arrives with 3D laser scanners for platform modeling

  • Apr 1: Finalizes 5-phase launch plan aligning with tidal window (0.8-knot ebb current)

  • Apr 3: Commences lifting operation with 12 synchronized jacks (8-hour duration)

  • Apr 4: “Step-by-Step” lateral relocation at 5m/hour speed

  • Apr 5:

      • 15:30 Final system check

      • 16:00 Wire rope severing

      • 16:01 Vessel enters water at 0.3m/s constant velocity

Key Performance Metrics:

  • Lifting height: 3.2m (Asian record)

  • Lateral accuracy: <15mm deviation

  • Airbag integrity: 100% (zero failures in 68 units)

  • Schedule compression: 60% faster than conventional methods

III. Global Recognition: From Technical Export to Industry Standards

Vietnam Maritime Administration Deputy Director Nguyen Van Hung praised: “This represents the most innovative shipbuilding solution in Southeast Asian history.” STRATEGIC MARINE immediately awarded a USD 2.8M follow-up contract and adopted Qingdao Evergreen’s technology as group standard.

Strategic Implications:

  1. Technology Export: First standardization of large vessel airbag launching

  2. Cost Advantage: 42% reduction vs traditional methods

  3. Safety Innovation: Developed high-altitude platform safety protocol (DNV-certified)

IV. Industry Transformation: Chinese Innovation Goes Global

According to International Shipbuilding Network data (2010-2015):

  • Airbag technology applied in 38 projects across 17 countries

  • Cumulative cost savings exceeding USD 500M

Qingdao Evergreen Maritime subsequently led the drafting of ISO/TC8 “Marine Auxiliary Equipment” standards, marking China’s transition from technology follower to global leader.

Project Director Yu Xinbo remarked: “When those 68 airbags erupted simultaneously, we weren’t just launching 6,800 tonnes of steel—we were propelling China’s shipbuilding industry onto the world stage.” This Vietnamese watershed moment now writes a new chapter in China’s journey from “Made in China” to “Created in China.”
