全球最大静音科考船中国造：20米以外鱼群感觉不到
全球最大静音科考船中国造：20米以外鱼群感觉不到
217
科技日报5月29日消息，如果一切按计划进行，“东方红3”号5月30日交付。
“‘东方红3’号是世界上获得挪威船级社水下辐射噪声最高等级——‘静音科考’级认证证书、排水量最大的海洋综合科考船。”“东方红3”号总设计师、中国船舶工业集团有限公司第七〇八所研究员吴刚告诉记者，该船多项指标国际领先，特别是低噪音控制指标达全球最高级别，“当船行驶时，水下20米以外的鱼群都感觉不到”。
螺蛳壳里做道场
总体专业是整个设计环节的起始点和抓总者，工作贯穿整个设计始终。总体专业主任设计师曲宁宁被吴刚形容为总设计师的左膀右臂。
曲宁宁说，作为一种高技术船舶，科考船的设计和建造难度较大，设计建造周期通常在4到6年，有的甚至达到了10年，是常规商船的好几倍。原因是与常规船相比，科考船的方案论证、界面协调、设备定制设计、布置优化调整的工作量要多很多。
科考船总布置设计首先要解决“兼顾”问题：在满足法规要求的前提下，兼顾船舶系统与科考系统，实现科考功能最大化。
对设计师来说，“兼顾”也是最难的。在主尺度和线型基本确定后，加上总体设计必须确保的作业视线、采样洁净度、振动噪声、电磁兼容等，各个系统的特殊要求，总布置属于“螺蛳壳里做道场”，必须将船上每个边边角角都充分利用。
“本船的总布置讨论前前后后进行了几十次，仅会议纪要就有几十页，厚厚一本，经过项目组努力，最终使本船的实验室面积和工作甲板的利用率均达到了同型船中的最高。”吴刚说，“东方红3”号具备了尽可能多的可扩展功能，5000多吨的排水量可完成7000吨科考船的任务。
多项技术领先行业
科考船的排水量较小，一般只有几千吨，空船重量的调整空间较小，因此对每一项设备的重量控制指标要求都很严。
船舶下水时，通过倾斜试验，可以确定船舶最终的空船重量重心。这也是设计师最紧张的时刻：空船重量如果估算过轻，会影响科考负载指标、船舶科考功能，此外需额外消耗更多压载水进行调整，这并不经济。
“东方红3”号正式倾斜试验完成后，空船实测重量比初始预估减轻了0.6%，重心高度略有下降，纵向位置向更有利配载的尾部略有移动，非常好地解决了科考船的浮态控制难题。
“这也说明项目团队已较好掌握了科考船又一项关键技术——空船重量重心控制技术。”吴刚告诉记者，其中的秘诀，既因为对整船做好了全局性规划，还因为对空船重量重心统计做到了前所未有的详细。“以前一般船型将全船系统和设备分成三四百项，对小项则做合并处理，对‘东方红3’号的统计则分成了800多项，最轻的设备只有几十公斤，最关键的是设计单位和建造船厂建立了统一动态的重量重心控制流程和体制。”
在概念设计阶段，船东中国海洋大学花了近一年半的时间，在考察了多艘国际先进科考船后，参照各船指标，希望能够建造一艘“能够保持长时间行业领先地位”的船舶，并结合自身需求，提出了个性化的方案。
科学家发现，船上普通电源所产生的电磁干扰，会影响精密实验仪器的工作。
“东方红3”号的一个创举，是在国内甚至全球首次提出科考船上“洁净电磁环境”概念。设计团队联手上海交通大学电子信息与电气工程学院的专家从基础突破，不仅满足了用户要求，还梳理出相应的规范和标准。
在吴刚看来，经历“东方红3”号项目历练，年轻的设计团队得到了很好的锻炼，各专业涌现出了不少青年骨干。
“七〇八所设计团队很年轻，但设计师非常敬业、业务能力也很强，工作一丝不苟。”中国海洋大学“东方红3”号建设工程部项目总指挥赵军和技术总监于胜这样评价。
The world's largest silent scientific research ship made in China: 20-meters beyond the fish school can not feel
The world's largest silent scientific research ship made in China: 20-meters beyond the fish school can not feel

Science and Technology Daily reported on May 29th that if everything goes according to plan, "Dongfanghong 3" will be delivered on May 30th.
"'Dongfanghong 3' is the world's highest level of underwater radiation noise from the Norwegian Classification Society - the 'quiet scientific test' certification, the largest marine scientific research ship with the largest displacement." Total design of "Dongfanghong 3" Wu Gang, a researcher at the 7th and 8th China National Shipbuilding Industry Corporation, told reporters that the ship has many international leading indicators, especially the low noise control indicators reaching the highest level in the world. “When the boat is driving, the fish is 20 meters underwater. The group can't feel it."
Dojo in the snail shell
The overall profession is the starting point and the master of the entire design process, and the work runs through the design. Qu Ningning, the chief professional designer, was described by Wu Gang as the chief designer's right arm.
Qu Ningning said that as a high-tech ship, the design and construction of scientific research vessels is difficult. The design and construction period is usually 4 to 6 years, and some even reach 10 years, which is several times that of conventional commercial ships. The reason is that compared with the conventional ship, the workload of the scientific research ship, such as program demonstration, interface coordination, equipment custom design, and layout optimization adjustment, is much more.
The general layout design of the scientific research ship must first solve the problem of "consideration": under the premise of meeting the requirements of the regulations, taking into account the ship system and the scientific research system, and maximizing the scientific examination function.
For designers, “consideration” is also the hardest. After the main scale and line type are basically determined, plus the line of sight, sampling cleanliness, vibration and noise, electromagnetic compatibility, etc., which must be ensured by the overall design, the special requirements of each system, the general arrangement belongs to the “snail case in the snail shell”, must be Every corner of the ship is fully utilized.
"The total layout of the ship was discussed dozens of times before and after the discussion. Only the minutes of the meeting were dozens of pages, thick one. After the efforts of the project team, the laboratory area and the working deck utilization rate of the ship were finally achieved. The highest in the same type of ship.” Wu Gang said that the “Dongfanghong 3” has as many expandable functions as possible, and the displacement of more than 5,000 tons can complete the task of 7,000 tons of scientific research vessels.
A number of technology-leading industries
The scientific research vessel has a small displacement, generally only a few thousand tons, and the adjustment space of the empty ship weight is small, so the weight control index of each equipment is very strict.
When the ship is launched, the ship's final empty ship's center of gravity can be determined by the tilt test. This is also the most tense moment for the designer: if the weight of the empty ship is estimated to be too light, it will affect the test load index and the ship's scientific research function. In addition, it needs to consume more ballast water for adjustment, which is not economical.
After the official tilt test of “Dongfanghong 3” was completed, the measured weight of the empty ship was reduced by 0.6% compared with the initial estimate, the height of the center of gravity was slightly decreased, and the longitudinal position moved slightly to the tail of the more favorable load, which solved the section very well. The ship's floating control problem.
"This also shows that the project team has mastered another key technology of the scientific research ship - the weight control technology of the empty ship." Wu Gang told reporters that the secret is not only because of the overall planning of the whole ship, but also Because the weight of the empty ship's weight center has achieved unprecedented detail. "In the past, the general ship type divided the whole ship system and equipment into three or four hundred items, and the small items were combined. The statistics of 'Dongfanghong 3' were divided into more than 800, and the lightest equipment was only a few dozen kilograms. The key is that the design unit and the construction shipyard have established a unified dynamic weight center of gravity control process and system."
In the conceptual design stage, the shipowner China Ocean University spent nearly a year and a half. After examining a number of international advanced scientific research vessels, and referring to the indicators of each ship, I hope to build a “can maintain a long-term industry leading position”. The ship, combined with its own needs, proposes a personalized program.
Scientists have discovered that the electromagnetic interference generated by ordinary power sources on board will affect the work of precision laboratory instruments.
A pioneering work of "Dongfanghong 3" was the first to propose the concept of "clean electromagnetic environment" on scientific research vessels at home and even in the world. The design team teamed up with the experts of the School of Electronic Information and Electrical Engineering of Shanghai Jiaotong University to break through the basics, not only satisfying the requirements of users, but also sorting out the corresponding norms and standards.
In Wu Gang’s view, after experiencing the “Dongfanghong 3” project, the young design team has been well trained, and many young talents have emerged in various professions.
“The seven-eighth design team is very young, but the designers are very dedicated, their business skills are very strong, and their work is meticulous.” Zhao Jun, chief projector of the construction project of “Dongfanghong 3” of Ocean University of China, and Yu Sheng, technical director of the company, commented. .
