智慧在多瑙河上闪光

-----永泰永安顺罗马尼亚气囊勇救“不水舟”

多瑙河，一个诗情画意的名字，白桦林中的鸟语，蝶恋蜂迷的花香，微风漪澜的河水，拥有三百条支流的多瑙河，让人们为之心潮澎湃。

多瑙河，一个象征勇气和力量的地方。约翰·施特劳斯的《蓝色的多瑙河》圆舞曲，总是给予人们生活的热情和奋斗的勇气。

2011年9月2日晚7点，永泰旗下永安顺工程公司，在美丽的多瑙河畔成功下水一艘“不水舟”，溅起的“多瑙河之波”奏响了一曲惊天动地的赞歌，为《蓝色多瑙河》增添了新的乐章。

八月的北京酷暑炎炎，永安顺公司接到一个电话：罗马尼亚船厂一艘液化气船在下水过程中出现事故，船体横倾在滑道上，客户询问能否拯救该船。随后的交流中，我们了解到欧洲一家著名打捞公司曾到该失事现场勘察过，随后提交的打捞方案却未得到德国船东的认可。

由于时间紧迫，船东方面要求永安顺公司首先出具技术方案，如果方案可行则直接到现场工作。永安顺人为难了，没有现场勘查，对方给出的资料又不完善，这个活怎么接呢？

智慧一 运筹帷幄，科技当家

时间紧迫，永安顺和船厂双方都开始了高速运转。船厂按照我方要求，现场测量各种数据，水下摸排绘图，随后资料迅速发往我公司。我们经过反复计算和推演，制定出三套气囊打捞下水方案，供船东参考和选择。由于气囊工程在欧洲尚无先例，船东和船厂对方案提出了很多质疑。我公司针对对方问题，通过绘图以及计算说明了各种方案的利弊。最终永安顺严谨的方案以及科学的态度打消了船东的疑虑，在一周内与我公司签订了合同，并预付100%合同款。通过该轮接触我们对德国船东工作严谨高效的态度也有了深刻的体会。

智慧二：多瑙河畔，一锤定音

合同签订的第三天，永安顺两名工程师经过14小时的飞行到达罗马尼亚边境城市Turnu Severin。这里与塞尔维亚隔多瑙河相望，直线距离仅1公里。

来不及看异国风情，来不及休息，工程师们放下行李就赶到了船厂。八月罗马尼亚的午后地面温度达到45度，现场2个小时的勘察后，工程师们心情沉重。

该船厂为50年代苏联援建厂，一直采用木滑道横向下水。由于滑道未得到良好的维护保养，在下水该6500 立方液化气船时，滑道和滑车大部分碎裂，船体搁浅在1.5米水深处的滑道上。船体纵倾9.8度，横倾9度，船底情况不明。

船厂和船东以及我方工程师进行了技术交流。船厂方面希望气囊顶升起事故船后，他们修复滑车，继续使用滑车来下水该船。船东方面则对此深表怀疑，但对气囊是否能够顺利使该船下水也心存疑虑。

我方建议在现场召开会议。针对船厂的继续使用滑车建议，我方要求潜水员下水勘察水下滑道情况：假设滑道完好，那么使用滑车下水对于双方都有利：我们只需顶升起船舶，清理掉已碎滑车即可。

然而潜水员的摸排和照片显示，水下滑道至少有4根无法继续使用，现场气氛十分凝重。但船厂仍然坚持滑车下水，提议可以更换部分水下滑道。船东和我方人员私下进行了商谈，我方认为滑车下水风险较大，气囊方案更加合理可行。

最终船东决定采用气囊顶升并下水的方案，要求我方全面负责现场指挥。

智慧三 坚忍不拔，鼎力相助

我方连夜开始补充、修订、分解打捞方案，对各个步骤进行了详细说明。第二天召开了现场技术交底会，指挥人员人手一份技术方案。

空运过来的气囊已经到达现场，根据方案人们开始摆放气囊。船底情况复杂，部分船底坐在滑道上，部分坐在滑车上，并且有1-2米深得水，加上工人没有操作经验，气囊就位工作进展缓慢。船底和水下地面距离最小只有30 厘米，潜水员无法钻入船底辅助作业，也造成了工作的困难。

当日船厂邀请来一位罗马尼亚造船业顶尖工程师，对我公司的技术方案进行审核和现场监督。该工程师我们称之为老法师，对我方案提出很多尖锐问题。我方既要从理论方面来证明方案的可行和安全性，又要现场处理遇到的各种困难，十分疲惫。

第三天，10只气囊完成精确定位摆放，随后气囊充气船首被缓慢升起。看到项目有了好的进展，现场工作人员精神为之一震，一鼓作气顺利移除了船首下破碎的滑车。

第七天，26只气囊完全顶起了船体，滑车清理完毕。

此时船体的横倾角恢复到7度左右，与我方提供的计算结果非常吻合。此前老法师认为船体在被气囊顶起后，船体可能产生侧滑。尽管我方提供了计算数据，表明侧滑不可能发生，但船厂仍坚持加装侧向横拉钢丝绳。待船体顶起后，实际结果是船体横倾角减小，横拉钢丝绳也没有任何拉力。在下水前，横拉钢丝又全部被拆掉。这以后船厂船东对我公司信心空前高涨。

智慧四 猛龙觉醒，飞鱼现象

这是一个难忘的日子，2011年月2日晚7点，多瑙河畔又恢复了往日的宁静，人们翘首以待激动人心的下水时刻。

船尾牵引钢丝缆缓缓发力，大船却纹丝不动。四周一片寂静，只有哗哗的水声和对讲机传来焦急的对话声。三分钟时，船体前进了大约2米，现场指挥人员协调牵引拖轮和拖车同时发力，5分钟时人们已经能够感觉到船体的运动了，窃窃私语声四处响起来，夹杂着压抑的兴奋和惶恐。大船好像一条苏醒的猛龙，慢慢开始舒展身躯，6分钟时船尾已经达到起浮水深。 随着船体逐渐起浮，气囊一条接一条从船底窜出，18长的大家伙呼啸着冲出来又重重得拍在水面。周围人群开始沸腾起来，每一条气囊的飞跃都伴随着人们兴奋的呼喊声：飞鱼！飞鱼！10分钟后船体顺利入水，完全起浮。

最先过来和我们拥抱的是老法师，接着是船东，船厂经理，周围人群也不停有人过来握手祝贺。夕阳下美丽的多瑙河畔一片欢腾。

罗马尼亚经历，我们不仅收获了项目成功的喜悦，也收获了友谊。船厂的工人米尔切多次邀约我们去附近游览，尽管我们找出各种理由拒绝也抵挡不住他的盛情。船东代表KARL先生，学识渊博体贴友善，在生活和项目上给了我们很多支持。还有哈特曼的小龙，和我们一起同甘共苦10天时间，在此一并表示真心感谢。

Wisdom shines on the Danube River

-----Qingdao Eversafe Romania airbag bravely rescued the "waterless boat"

The Danube, a poetic name, the bird songs in the birch forest, the flowers of butterflies and bees, the ripples of the river in the breeze, the Danube with 300 tributaries, makes people feel surging.

The Danube, a place symbolizing courage and strength. Johann Strauss's Blue Danube waltz always gives people the passion of life and the courage to struggle.

At 7 PM on September 2nd, 2011,  Eversafe Engineering Company, a subsidiary of Qingdao Evergreen Maritime, successfully launched a "non-water boat" on the beautiful Danube River. The "Danube River wave" splashed out played a song of earth-shaking praise and added a new chapter to the Blue Danube.

In August, Beijing was sweltering.  Eversafe Company received a call: a liquefied gas ship at a Romanian shipyard had an accident during its launch, causing the ship to stuck on the slipway. The customer inquired if the ship could be salvaged. During the subsequent communication, we learned that a renowned European salvage company had inspected the accident site and submitted a salvage plan, but it was not accepted by the German shipowner.

Due to the lack of time, the shipowner asked  Eversafe Company to first issue a technical plan and go to the site directly if the plan was feasible.  Eversafe company was in a dilemma. Without on-site investigation and the incomplete data provided by the other party, how could we take over this job?

Wisdom 1. Find Strategy Far Away , Technology is the Key

Time was of the essence, and both Eversafe and the shipyard began to operate at high speed. The shipyard measured various data on-site and conducted underwater surveys and mapping according to our requirements, and then promptly sent the materials to our company. After thorough calculations and simulations, we developed three airbag salvage plans for the shipowner to consider and choose from. Since the airbag project had no precedent in Europe, the shipowner and the shipyard raised many questions about the plans. Our company addressed these concerns by providing detailed drawings and calculations that explained the pros and cons of each plan. Ultimately,  Eversafe's rigorous approach and scientific attitude reassured the shipowner, who signed the contract with us within a week and prepaid 100% of the contract amount. Through this interaction, we gained a deep appreciation for the shipowner's meticulous and efficient work ethic.

Wisdom 2: One Hammer down on the Danube

Three days after the contract was signed, two engineers from  Eversafe flew 14 hours to Turnu Severin, a border city in Romania. It is just 1km away from Serbia across the Danube river.

Without time to see the exotic scenery or rest, the engineers left their luggage and rushed to the shipyard. In August, the temperature in the afternoon in Romania reached 45 degrees Celsius. After two hours of on-site investigation, the engineers were in a heavy mood.

The shipyard, built with Soviet aid in the 1950s, has traditionally used a wooden slipway for launching ships. Due to poor maintenance of the slipway, when launching the 6,500 cubic meter liquefied gas vessel, most of the slipway and pulley broke, causing the hull to run aground on the slipway at a depth of 1.5 meters. The ship was found with a longitudinal inclination of 9.8 degrees and a transverse inclination of 9 degrees, with the condition of the bottom remaining unknown.

The shipyard, the shipowner, and our engineers engaged in technical discussions. The shipyard hopes that after the airbag rises to lift the accident vessel, they can repair the pulley and continue using it for launching the vessel. However, the shipowner is skeptical about this approach and also has doubts about whether the airbag will successfully enable the vessel to be launched.

We suggest holding a meeting on site. In view of the shipyard's suggestion to continue using the trolley, we ask the diver to go down to investigate the water slide: if the slide is in good condition, then using the trolley to go down to the water will be beneficial for both sides: we only need to lift the ship and clean up the broken trolley.

However, the divers' inspection and photographs revealed that at least four underwater slides were no longer usable, creating a tense atmosphere on site. Despite this, the shipyard insisted on lowering the pulley into the water and suggested replacing some of the underwater slides. The shipowner and our team held private discussions, and we concluded that lowering the pulley posed significant risks, while the airbag solution was more practical and feasible.

Finally, the shipowner decided to use the plan of lifting the airbag and launching the ship, and asked us to take full responsibility for the on-site command.

Wisdom 3: Persistence and Cooperation

We began to supplement, revise and decompose the salvage plan overnight, and made detailed explanations of each step. The next day, a technical briefing meeting was held on site, and each commander had a technical plan.

The airbags transported by air have arrived at the site, and according to the plan, people began to place them. The condition of the ship's bottom is complex, with some parts on the slide and others on the trolley, and there is 1-2 meters of water. Due to the lack of operational experience among the workers, the placement of the airbags has been slow. The distance between the ship's bottom and the underwater ground is as little as 30 centimeters, making it impossible for divers to enter the ship's bottom to assist with the work, which further complicates the task.

On that day, the shipyard invited a top engineer from Romania's shipbuilding industry to review and supervise our technical proposal on-site. We referred to this engineer as the' old master,' who raised many critical questions about our proposal. We had to prove the feasibility and safety of the proposal from a theoretical standpoint and address various on-site challenges, which left us extremely exhausted.

On the third day, 10 airbags were precisely positioned and inflated, and the bow of the boat was slowly raised. Seeing that the project had made good progress, the staff on site were shocked and removed the broken pulley under the bow in one go.

On the seventh day, 26 airbags fully lifted the hull and the pulley was cleaned up.

At this point, the ship's transverse inclination angle had returned to about 7 degrees, which closely matched the calculation results we provided. Previously, the old master believed that after the ship was lifted by the airbags, it might slide sideways. Despite our data showing that such a sliding would be impossible, the shipyard insisted on adding lateral steel cables. After the ship was lifted, the transverse inclination angle actually decreased, and the lateral steel cables showed no tension. Before the ship was launched, all the lateral steel cables were removed. Since then, the shipyard and shipowner have shown unprecedented confidence in our company.

Wisdom 4: Noah’s Ark Launching, Fish Flying

It was a memorable day. At 7 PM on the evening of February 2, 2011, the Danube River was quiet again and people were eagerly awaiting the exciting moment of entering the water.

The ship's stern was slowly being pulled, but the large vessel remained motionless. The surroundings were silent, with only the sound of water and anxious chatter from the walkie-talkies. After three minutes, the ship had moved forward about 2 meters. The on-site command personnel coordinated the towing tug and trailer to work together, and by the fifth minute, people could already feel the movement of the ship. Whispered conversations filled the air, mingled with a mix of suppressed excitement and fear. The large vessel seemed to awaken like a whale, slowly stretching out. By the sixth minute, the stern had reached the water's surface. As the ship gradually rose, airbags emerged one after another from the bottom of the hull. The 18-meter-long marine airbags roared out and slammed heavily onto the water. The crowd around began to erupt in cheers, each leap of an airbag accompanied by excited shouts: Flying fish! Flying fish! Ten minutes later, the ship smoothly entered the water and was fully afloat.

The old master was the first to come and hug us, followed by the shipowner and the manager of the shipyard. People kept coming to shake hands and congratulate us. The beautiful Danube river was jubilant in the sunset.

Through our experience in Romania, we not only experienced the joy of project success but also forged lasting friendships. The shipyard worker, Mircea, repeatedly invited us to visit nearby attractions, and despite our various excuses, we could not resist his warm invitations. Mr.Karl, the shipowner's representative, was knowledgeable, considerate, and friendly, offering us significant support both in our daily lives and during the project. Additionally, Xiao Long from Hartmann, who shared the hardships with us for 10 days, we extend our sincere gratitude to him as well.
