2月23日，我国自主研发的第四代海洋工程安装船“志高号”和“志远号”，在江苏南通顺利竣工。这两艘船的主要任务是将风机，也就是我们常说的“大风车”运送至深远海，并进行安装等施工作业。这两艘工程安装船的制造完工，对推动深远海风电规模化开发，加速能源绿色低碳转型有着重要意义。

Next to China's fourth-generation offshore engineering installation vessel "Zhi Yuan Hao" is the offshore engineering crane ship "Zhi Gao Hao," which was completed around the same time. These two vessels were jointly designed and complement each other, forming the optimal combination for China's offshore engineering installations. They can operate in waters kilometers away from the shore, providing strong support for China's offshore wind power projects in deep and distant seas.

This offshore wind power "Gemini" installation vessel represents China's fourth-generation wind power marine engineering equipment and is also the latest generation of wind turbine installation vessel globally. Compared to third-generation marine engineering equipment, it has achieved a qualitative improvement in technology and performance. This "Gemini" pair of marine engineering vessels is among China's strongest in terms of wind and wave resistance, boasting the best comprehensive installation capabilities, highest operational efficiency, and most advanced intelligent features. Chief Engineer Zhang Weifeng explained that the two vessels can complete the installation of a single offshore wind turbine in just two to three days, marking a % increase in installation speed compared to third-generation wind turbine installation vessels. Additionally, they can withstand -level strong winds and -meter waves, positioning them as core equipment in China's efforts to advance large-scale development of deep-sea wind power.

As the fourth-generation marine engineering installation vessels in our country, the "Zhihao" and "Zhiyuan" ships excel in operations such as deep-sea lifting and pile driving. What unique designs and advanced technologies do they possess? Next, follow our reporter on board to get a close-up look at these two powerful tools for offshore wind power installation.

These two vessels are the perfect pair for offshore equipment installation, each excelling in their own specialties. The "Zhihao" primarily handles lifting and foundation pile driving, resembling a "Popeye" with its incredibly powerful "arms." The massive red pile cylinder at the stern, along with the meter-long boom at the top, forms its main lifting system. Over here, the enormous anchor-like structure is its main hook, functioning like a human hand, capable of hoisting tons of cargo—equivalent to lifting several family cars at once. It can rotate a full degrees, doubling the rotation speed compared to the previous generation of offshore installation vessels.

The reporter visited the "Zhiyuan" and discovered that the most significant difference from the "Zhigaohao," which operates while floating on the sea surface, is the "long legs" of the "Zhiyuan," which extend several meters. These are the gray structures behind the reporter. This feature allows the ship to anchor deeply into the seabed, enabling it to perform installation operations for offshore wind turbines in waters several meters deep. The cylindrical red tower is the crane of the "Zhiyuan," which can lift cargo up to a height equivalent to several stories. The final installation tasks of the offshore units, especially the installation of the nacelles and blades of the wind turbines, are completed by this crane.

那么“志高号”和“志远号”是如何共同完成一台风机的安装呢？首先，“志高号”凭借“大铁臂”将钢管桩吊起插入水中，吊起打桩锤，把钢管桩打入海底，完成基础打桩。随后，“志远号”利用 “大长腿”稳稳扎入海底，并将船体升高，为海上安装提供稳固的平台。它把塔筒吊装到基础上，将风机机舱、扇叶逐一安装到塔筒顶端，这样风机就安好了。两艘船紧密配合，能够满足单机容量25兆瓦的深远海一体化海上风电高效率施工作业需求。（来源：央视网）
