According to CCTV News, the launching ceremony of North Korea 's newly built 5,000-ton destroyer was held at the Chongjin Shipyard on the 21st local time . Kim Jong-un, General Secretary of the Workers' Party of Korea and Chairman of the State Affairs Commission, attended the ceremony.

A serious accident occurred during the launching of a newly built destroyer. During the launching process, due to unskilled command and careless operation, the parallelism of the chassis movement was not ensured, causing the launching slide at the stern to break away and run aground first, holes in some sections of the bottom of the ship caused the hull to become unbalanced, and the bow part did not leave the slipway.

据央视新闻报道，当地时间21日，朝鲜新建造的5000吨级驱逐舰下水仪式在清津造船厂举行。朝鲜劳动党总书记、国务委员长金正恩出席仪式。

新建驱逐舰在下水过程中发生严重事故。驱逐舰下水过程中，因指挥不熟练、操作不慎，未能保障底盘移动平行度，致使船尾部分的下水滑板先脱离搁浅，部分区段船底破孔导致船体失衡，船首部分未脱离船台。

Kim Jong-un witnessed the whole process of the accident and criticized that the accident was "caused entirely by carelessness, irresponsibility and unscientific empiricism", which damaged the dignity and self-esteem of North Korea. The responsibility for the accident lies entirely with the relevant units such as the Ministry of Munitions Industry of the Central Committee of the Workers' Party of Korea, the Central Ship Design Institute and the relevant personnel of the Chongjin Shipyard.

金正恩目睹了事故全过程，批评称这起事故“完全由做事不慎、不负责任和不科学的经验主义所造成”，损害了朝鲜的尊严与自尊心。事故责任完全在于劳动党中央委员会军需工业部、中央船舶设计研究所等相关单位和清津造船厂有关人员。

Kim Jong-un said that this irresponsible and serious mistake will be investigated at the plenary meeting of the Central Committee of the Workers' Party of Korea to be held next month , and stressed that "repairing the destroyer as soon as possible is a political issue directly related to the state's authority, not a simple business issue." He demanded that the repair work be completed "unconditionally" before the plenary meeting next month. The report also said that Kim Jong-un gave important instructions on the work of the accident investigation team.

It is reported that the Political Bureau of the Central Committee of the Workers' Party of Korea announced a resolution on May 21, that the Political Bureau of the Central Committee of the Workers' Party of Korea decided to convene the 12th Plenary Session of the 8th Central Committee of the Workers' Party of Korea in late June to make a mid-term summary of the implementation of important policies of the Party and the State of North Korea in 2025 and discuss and decide on the work in the second half of the year.

金正恩说，将在下月召开的劳动党中央委员会全会上对这一不负责任的严重错误进行立案审查，并强调：“尽快修复驱逐舰是直接关乎国家权威的政治问题，而非单纯的业务性问题。”他要求，在下月全会召开前“无条件”完成修复工作。报道还说，金正恩就事故调查组工作作了重要指示。

据悉，朝鲜劳动党中央委员会政治局5月21日宣布决议，朝鲜劳动党中央委员会政治局决定于6月下旬召开劳动党八届十二中全会，对朝鲜党和国家2025年重要政策执行情况进行中期总结，讨论决定下半年工作。

Of course, it is not an isolated case that a new warship has just been launched and an accident has occurred:

当然新军舰刚下水就出事这种情况也绝非孤例：

US Littoral Combat Ship (2023):

According to a China Daily report on April 22, 2023, a US Navy Freedom - class littoral combat ship recently collided with an attending tugboat during its launch ceremony, producing a "loud noise". The launch ceremony was held at Marinette Marine Shipyard in Wisconsin.

As per procedure, the littoral combat ship was to be pulled sideways into the river by the tugboat. However, as the ship slid sideways into the water, it immediately crashed into the tugboat. The huge waves created during the launch nearly submerged the tugboat.

美国濒海战斗舰（2023年）：

据中国日报2023年4月22日消息，美国海军“自由”级濒海战斗舰日前在下水仪式中发生事故，与一艘配套拖船相撞，现场发出“一声巨响”。据悉，下水仪式在威斯康星州的马里内特造船厂举行。

按照程序，位于岸上的战斗舰将由辅助拖船从侧位拉入河道。当这艘濒海战斗舰侧滑入水时，却立刻撞上了拖船，下水时击发的巨大波浪几乎淹没了拖轮。

Indian frigate (2016)

印度护卫舰（2016年）

In December 2016, when an Indian Brahmaputra - class frigate was being refitted and undocking at the Mumbai Naval Dockyard, it capsized due to an operational error, killing two people and injuring 15. The accident exposed the technical and management loopholes of the Indian shipbuilding industry, and was even ridiculed as " capsulating a warship in its own shipyard . "

2016年12月，印度“布拉马普特拉”级护卫舰在孟买海军船坞完成改装出坞时，因操作失误导致舰体侧翻，造成2人死亡、15人受伤。事故暴露印度造船业技术和管理漏洞，甚至被嘲讽为“在自家船厂玩翻军舰”。

The frigate belonging to the Indian Western Fleet has completed maintenance in the dry dock of the Mumbai Naval Shipyard and is ready to be launched for sea trials. All they need to do is open the valve connecting the dock to the sea. When the water level in the dock is level with the sea surface, the workers can open the dock door and use a tugboat to tow the warship away. This operation has been performed countless times here. However, soon after the seawater poured into the dock, someone suddenly discovered that the warship with a displacement of nearly 4,000 tons tilted to the left, so some people began to shout loudly, but the situation was out of control. The warship tilted rapidly, and the " creaking " sound of the metal structure deforming came one after another. In less than a minute, the warship flipped over on the bottom of the dock and almost knocked down a missile patrol boat that was being renovated next to it .

隶属印度西部舰队的护卫舰在孟买海军修船厂干船坞内完成检修，准备出坞海试。只需打开船坞与大海的连通阀，待到坞内水位和海面齐平时，工人们就可打开坞门，用拖船把军舰拖走，这样的操作在这里已不知道执行过多少次了。然而，海水涌入坞内不久，突然有人发现排水量近4000吨的军舰发生左倾，于是一些人开始大声呼喊，可局面已经无法收拾，军舰快速倾斜，金属结构变形时发出的“嘎吱”声此起彼伏，不到一分钟，军舰咣当一下侧翻在船坞底板上，差点撞倒旁边一艘正在翻修的导弹巡逻艇。

Everyone present was stunned, and no one even thought of closing the dock connecting valve that was flooding. As a result, seawater continued to pour in and flooded the chimney of the warship. The accident caused the death of two sailors on board, one of whom fell to his death when jumping off the ship, and the other was trapped and drowned in the ship. Another 15 people were injured. It is reported that Indian Navy Chief of Staff Lanba quickly rushed to Mumbai to deal with the aftermath. The Indian Ministry of Defense promised to disclose more investigation information to the outside world and bring the perpetrators to justice.

在场的人全都呆若木鸡，连灌水的船坞连通阀也没人想起去关，结果海水持续涌入，一直淹到军舰的烟囱口。事故造成2名正在舰上的水兵遇难，其中一人在跳船时摔死了，另一人被困在舰内溺死，另有15人受伤。据悉，印度海军参谋长兰巴迅速赶到孟买善后，印度国防部承诺会向外界公开更多调查情况，法办肇事者。

Ship launching - be careful!

船舶下水——千万注意！

Launching a ship is a key step in shipbuilding, and a slight mistake can lead to a serious accident. Whether it is operating errors, unskilled command, equipment failure, environmental factors, etc., they may become the fuse for the accident, which will not only cause huge economic losses, but also pose a serious threat to personnel safety. For example, in the case of the Indian "dock shipwreck" mentioned above, although the Indian Navy has frequent accidents, the strange thing of a warship capsizing in the dock is still surprising, and this happened in the historic Mumbai Naval Shipyard!

Therefore, the launch of a ship must strictly follow scientific operating procedures and safety standards to ensure that every link is foolproof. Next, let's take a closer look at the ship launching methods and matters that need to be paid attention to.

船舶下水是舰艇建造的关键环节，稍有不慎就可能引发严重事故。无论是操作失误、指挥不熟练，还是设备故障、环境因素等，都可能成为引发事故的导火索，不仅会造成巨大的经济损失，还可能对人员安全构成严重威胁。比如以上印度“船坞沉船”的案例，尽管印度海军事故频发，但军舰在坞内倾覆这样的怪事还是让人跌破眼镜，而且这种事居然发生在历史悠久的孟买海军修船厂！

因此，船舶下水必须严格遵循科学的操作规程和安全标准，确保每一个环节都万无一失。接下来，我们就来详细了解一下船舶下水方式和需要注意的事项。

• Gravity launch

Longitudinal launching: The ship slides into the water along the length of the ship. The ship enters the water first, and uses gravity and the slide to launch the ship smoothly. This method has a long braking distance and requires a large water area. It is suitable for ships of different launching weights and ship types, but the launching process is complicated and the ship has a large stroke in the water. Generally, the width of the water area is required to be no less than three times the length of the ship.

• 重力式下水

纵向下水：船舶沿船长方向滑入水中，船首先进入水中，利用重力和滑道使船舶顺利下水。这种方式制动距离长，要求水域面积大，适用于不同下水重量和船型的船舶，但下水工艺复杂，船舶在水中的冲程较大，一般要求水域宽度不小于三倍船长。

Horizontal launching: The ship slides in the direction of the ship's width, and one side enters the water first. It is divided into two types: horizontal floating type and horizontal falling type. The floating ship slides into the water along the slideway, and the braking distance is short, but there are many slideways, which can easily cause inconsistent sliding speeds and cause accidents; in the falling type launching, the ship falls into the water together with the launching frame and the slide board, and the ship rolls violently, which requires higher lateral strength and stability of the ship.

横向下水：船舶按船宽方向滑移，一舷首先入水。分为横向浮起式和横向坠落式两种。浮起式船舶沿滑道滑移到水中，制动距离短，但滑道多，易造成滑移速度不一致，引发事故；坠落式下水时船舶连同下水架、滑板一起堕入水中，船舶横摇剧烈，对船舶横向强度和稳性要求较高。

• Floating launching

Dry dock launching: water is poured into the dry dock for building ships. The ship floats up due to the buoyancy of the water. When the water surface in the dock is flush with the water level outside the dock, the dock door is opened and the ship is towed out of the dock. This method is simple and easy to implement, with good safety and processability, but the initial investment is large. The Indian frigate in the above case was launched using a dry dock. At that time, based on the on-site video and photos, several retired Indian naval officers believed that there might be problems with the port side support pier and keel pier of the frigate. When the dock was filled with water, the water flow caused the support pier with hidden dangers to move, causing the hull to tilt to the left. At this time, the water level in the dock was too low to hold up the hull, and the entire warship capsized to the left.

Floating dock launching: first put the floating dock in place, align the track on the dock floor with the track of the horizontal slipway on the shore, move the ship into the floating dock with a slipway trolley, then detach the floating dock from the shore, tow the ship to the deep water area, pump ballast water into the ballast tank of the floating dock, increase the draft of the floating dock, and then the ship will float out of the dock. Its cost is low, and the launching operation is stable and safe, but the operation is complicated, and most of the time it needs to be equipped with a deep-water sinking pit.

• 漂浮式下水

干船坞下水：将水注入建造船舶的干船坞，船舶依靠水的浮力浮起，当坞内水面与坞外水位平齐时，打开坞门，将船舶拖曳出坞。该方式简便易行，安全性、工艺性较好，但初始投资较大。上述案例中的印度护卫舰就是采用干船坞下水，当时根据现场视频和照片，多名印度退役海军军官认为护卫舰的左舷支撑边墩和龙骨墩可能存在问题，船坞灌水时，水流导致有隐患的支撑墩移动，导致舰体左倾，而此时坞内水位又太低，不足以将舰体托起，结果整艘军舰向左倾覆。

浮船坞下水：先使浮船坞就位，坞底板上的轨道和岸上水平船台的轨道对准，用船台小车将船舶移入浮船坞，然后浮船坞与岸脱离，将船拖到深水区，向浮船坞的压载舱打入压载水，浮船坞吃水增加，船舶自浮出坞。其造价较低，下水作业平稳安全，但作业复杂，多数时候要配备深水沉坞坑。

• Mechanized launching
• 机械化下水

Mechanized launching by longitudinal boat ramp slide: The ship is built on an integral boat ramp or a segmented boat ramp with rollers. When launching, the boat ramp is pulled into the water by a winch along the track on the inclined slipway. This type of slide has low technical requirements and simple hydraulic construction, but is only suitable for launching small ships.

Two-point longitudinal slide mechanized launching: two separate launching vehicles are used to support the launching ship, and the ship can be directly towed from the horizontal slipway to the inclined slide for launching. It has a simple structure and is easy to operate, but it will generate a large head end pressure when floating at the stern.

纵向船排滑道机械化下水：船舶在带有滚轮的整体船排或分节船排上建造，下水时用绞车牵引船排沿着倾斜船台上的轨道将船舶送入水中。该方式滑道技术要求较低，水工施工较简单，但仅适用于小型船舶的下水作业。

两支点纵向滑道机械化下水：使用两辆分开的下水车支撑下水船舶，可直接将船舶从水平船台拖曳到倾斜滑道上使船舶下水。其结构简单、操作容易，但艉浮时会产生很大的首端压力。

Mechanized launching by longitudinal slide of wedge-shaped launching vehicle: the launching vehicle frame surface on the slide is horizontal or slightly sloped, and the ship floats flat when launched, and no head end pressure is generated. It is suitable for launching larger ships, but there are requirements for the water depth at the end of the slide, and the hydraulic construction volume is large and the investment is high.

Launching by ship lift: A large platform for carrying ships is built on the quayside, and a winch is used as a launching facility for vertical lifting. This method has a compact structure and is suitable for shipyards with small plant areas and limited waters. It also has stable operation and high efficiency, but it has great restrictions on the size of ships and is only suitable for small and medium-sized ships.

楔形下水车纵向滑道机械化下水：滑道上的下水车架面是水平的或稍有坡度的，船舶下水时是平浮起来的，不会产生首端压力，适用于较大的船舶下水，但对滑道末端的水深有要求，水工施工量大、投资高。

升船机下水：在岸壁处建造承载船舶的大型平台，利用卷扬机做垂直升降的下水设施。该方式结构紧凑，适用于厂区狭小、水域受限的船厂，且作业平稳、效率高，但对船舶尺度限制大，只适用于中小型船舶。

The launch of a ship is a key step in the shipbuilding process, involving complex operations and numerous technical details. A series of precautions must be strictly followed to ensure safety and success. Pay close attention to the ship's motion status, stress conditions and changes in the surrounding environment, and use monitoring equipment and technical means to promptly discover problems and make adjustments. If the ship is found to be tilting or sliding at an abnormal speed, take immediate measures to adjust. Ship launching accidents often cause huge economic losses and casualties, so it is necessary to attach great importance to and strictly follow the precautions.

船舶下水是船舶建造过程中的关键环节，涉及到复杂的操作和众多的技术细节，必须严格遵循一系列的注意事项以确保安全和成功。密切关注船舶运动状态、受力情况和周围环境变化，通过监测设备和技术手段及时发现问题并调整，如发现船舶倾斜或下滑速度异常，立即采取措施调整。船舶下水事故往往造成巨大经济损失和人员伤亡，必须高度重视并严格遵循注意事项。
