青島永泰長榮，船舶上排下水氣囊的技術(shù)革新與工程價值

jimosea

        經(jīng)過 20 余年的使用經(jīng)驗積累，國內(nèi)外多數(shù)造船廠已十分熟悉船用氣囊上排下水這一新技術(shù)（其亦可作為沉船打撈氣囊、助浮氣囊和堵水封堵氣囊使用），但部分新用戶仍對其缺乏信心。

為此，青島永泰長榮總結(jié)以下氣囊優(yōu)勢，以打消客戶顧慮：

1. 顯著的成本節(jié)約

• 采購與運營成本低：與建造干船塢或購置大型起重設(shè)備相比，氣囊的采購成本顯著更低。此外，其無需長期維護復(fù)雜設(shè)施，可減少 30%-50% 的資本投入。
• 維護簡便：僅需定期檢查氣囊外部、閥門等部件，無需專用維護設(shè)備，大幅降低人工與時間成本。
  

2. 高操作靈活性與穩(wěn)定性

• 浮力可控：通過調(diào)節(jié)氣囊內(nèi)部氣壓，可精準(zhǔn)控制浮力以支撐船體重量，避免傳統(tǒng)滑道下水時因摩擦不均導(dǎo)致的失衡問題（如朝鮮驅(qū)逐艦事件中滑板脫落引發(fā)的船體傾斜）。
• 姿態(tài)靈活調(diào)整：可通過逐步充放氣控制船體傾斜角度，確保下水過程更平穩(wěn)。例如，參考文獻中提及的 “尾部傾斜” 技術(shù)借助重力自然入水，可降低機械干預(yù)風(fēng)險。
  

3. 大幅降低安全風(fēng)險

• 規(guī)避傳統(tǒng)事故隱患：傳統(tǒng)滑道下水易因滑板平行度偏差（如朝鮮事件中船尾滑板先脫落導(dǎo)致船體損傷）或摩擦系數(shù)突變引發(fā)事故。氣囊通過均勻承壓實現(xiàn)風(fēng)險分散。
• 抗環(huán)境干擾能力強：氣囊對潮汐、風(fēng)力等外部因素適應(yīng)性強，可減少突發(fā)外力對船體的影響。
  

4. 卓越的適用性與便利性

• 運輸存儲便捷：氣囊放氣后體積小巧、重量輕，可快速運輸至不同場地，非常適合臨時施工或偏遠造船廠。
• 應(yīng)用場景多樣：適用于各種噸位船舶（從小型漁船到 5000 噸級驅(qū)逐艦）及復(fù)雜地形（如傾斜海岸線）。
  

5. 提高施工效率

• 快速部署：無需長期建造滑道或干船塢，氣囊可在數(shù)小時內(nèi)完成部署，縮短項目周期。例如，朝鮮事件中受損船體修復(fù)耗時約兩周，而氣囊部署僅需數(shù)小時。
• 可重復(fù)使用：氣囊使用壽命長（高品質(zhì)產(chǎn)品可重復(fù)使用 50 次以上），適合多次船舶下水。
  

案例對比：傳統(tǒng)滑道 vs. 氣囊下水

• 朝鮮驅(qū)逐艦事件（傳統(tǒng)滑道）：滑板脫落導(dǎo)致船體失衡受損，修復(fù)耗時約兩周。
• 氣囊解決方案：若使用氣囊，可通過壓力控制實時調(diào)整姿態(tài)，避免結(jié)構(gòu)損傷，修復(fù)時間可縮短至 2-3 天。
  

總結(jié)：

       青島永泰長榮船用上排下水氣囊憑借低成本、高安全性與強適應(yīng)性，成為現(xiàn)代船舶下水的優(yōu)選方案，適用于各類規(guī)模造船廠或應(yīng)急修復(fù)場景。

其技術(shù)原理與排水管道堵水氣囊（如大連案例中展現(xiàn)的密封性能與規(guī)格適應(yīng)性）具有共通性，均體現(xiàn)了船舶上排下水氣囊在工程領(lǐng)域的靈活應(yīng)用。

Advantages of Marine Launching Airbags Compared to Traditional Launching Methods


After more than 20 years using experience, most shipyard are very familiar with the NEW technologies of marine launching airbags, which can also used as salvage airbag and water-blocking airbags, but there still are some end-users being not confident with it. So, Qingdao Evergreen summarize below advantages of these airbags to address customers’ concern:

1. Significant Cost Savings
      ? Low procurement and operational costs: Compared to constructing dry docks or purchasing large-scale lifting equipment, the purchase cost of airbags is considerably lower. Moreover, they eliminate the need for maintaining complex facilities over the long term, reducing capital investment by 30%-50%.

      ? Easy maintenance: Only regular inspections of the airbag’s exterior, valves, and other components are required, eliminating the need for specialized maintenance equipment and drastically reducing labor and time costs.

2. High Operational Flexibility and Stability
      ? Controllable buoyancy: By adjusting the air pressure inside the airbags, the buoyancy can be precisely controlled to support the ship’s weight, avoiding imbalances caused by uneven friction in traditional slipway launches (e.g., the detachment of skids leading to ship tilting, as seen in the North Korean destroyer incident).

      ? Flexible attitude adjustment: The ship’s tilt angle can be controlled by gradually deflating or inflating the airbags, ensuring a smoother launching process. For instance, the “aft tilting” technique mentioned in the references leverages gravity for a natural water entry, minimizing mechanical intervention risks.


3. Substantial Reduction in Safety Risks
      ? Avoidance of traditional accident risks: Traditional slipway launches are prone to accidents due to parallelism deviations in skids (e.g., the stern skid detaching first in the North Korean incident, causing hull damage) or sudden changes in friction coefficients. Airbags distribute risks evenly through uniform pressure bearing.

      ? Strong resistance to environmental disturbances: Airbags adapt well to changes in tides, wind, and other external factors, reducing the impact of sudden forces on the hull.

4. Outstanding Applicability and Convenience
      ? Easy transportation and storage: When deflated, airbags are compact and lightweight, enabling rapid transportation to different sites—ideal for temporary construction or remote shipyards.

      ? Versatile application: Suitable for ships of various tonnages (from small fishing boats to 5,000-ton destroyers) and complex terrains (e.g., inclined shorelines).

5. Improved Construction Efficiency
      ? Quick deployment: No need for prolonged construction of slipways or dry docks; airbags can be deployed within hours, shortening project timelines. For example, repairing the damaged hull in the North Korean incident took about two weeks, whereas airbag deployment would take only a few hours.

      ? Reusability: Airbags have a long lifespan (high-quality products can be reused over 50 times), making them suitable for multiple ship launches.

Case Comparison: Traditional Slipway vs. Airbag Launching

  ? North Korean Destroyer Incident (Traditional Slipway): Skid detachment caused hull imbalance and damage, requiring approximately two weeks for repairs.


  ? Airbag Solution: If airbags had been used, real-time attitude adjustments via pressure control could have prevented structural damage, reducing repair time to 2-3 days.

Summary

Marine launching airbags are the preferred choice for modern ship launches due to their low cost, high safety, and strong adaptability, suitable for all-sized shipyards or emergency repair scenarios. Their technical principles share similarities with water-blocking airbags for drainage pipes (e.g., the sealing performance and specification adaptability demonstrated in the Dalian case), both reflecting the flexible application of inflatable tools in engineering fields.
