On October 9th, the flame lighting ceremony for China's 15th National Games, 12th National Games for Persons with Disabilities and 9th National Special Olympic Games was held on Longxue Island in Nansha District, Guangzhou. This flame-gathering ceremony was extraordinary, because it relied on China's advanced equipment and technology to collect combustible ice and associated gas extracted from a cold seep at a depth of over 1,500 meters in the South China Sea. The "source flame" was ignited using electricity converted from solar energy.

In 2015, the "Haima Cold Seep" was first discovered on the deep seafloor of the South China Sea by the Guangzhou Marine Geological Survey (GMGS) using the Haima remotely operated vehicle (ROV). It remains the largest known active deep-sea cold seep system on Earth. According to Wang Weiwei, Deputy Director of the Science and Technology Department of the GMGS, "Cold seep systems are typically accompanied by the formation and evolution of natural gas hydrates—commonly known as combustible ice. Collecting the 'source flame' at the Haima cold seep area allows us to use this clean and efficient energy for ignition, aligning with the Games' principles of 'green, inclusive, open, and clean.' Moreover, the cold seep area can vividly demonstrate the coexistence of gas and liquid in combustible ice, making it an excellent opportunity for science education."

The scientific research vessel undertaking the "source flame" mission is named "Haiyang Dizhi-2". According to Chen Zongheng, Deputy Director of the Marine Technical Methods Institute of the GMGS, the vessel is a rare new-generation research ship capable of both marine scientific research and deep-sea engineering operations in China. It can independently conduct marine scientific research including environmental assessments, geological sampling, and geophysical investigations, and is also capable of marine engineering tasks such as subsea cable laying, deep-water salvage, saturation diving, and wind power exploration, providing a highly efficient platform for this deep-sea flame collection.

The highlight of the vessel is the 4,500-meter-class Haima ROV, which also served as the "pioneer of flame collection" for this deep-sea mission. The mission fully leveraged two key strengths of the Haima ROV. The first is its powerful functional expansion and integration capacity, which enabled the integration of the "source flame" collection device and allowed for the integration and control of different types of pressure-retaining and pressure-resistant units. And the second lies in its accuracy in deep-sea operations, enabling it to locate the cold seep leakage points in complex underwater environments, and successfully collect the "source flame" through delicate manipulations with its robotic arms.

10月9日，十五运会和残特奥会火种采集仪式在广州市南沙区龙穴岛科考码头举行。这次的火种采集不一般，依托的是我国高新装备技术，于南海水深1500多米处采集冷泉口溢出的可燃冰及伴生气，利用太阳能转化而成的电能实现深海引燃。

2015年，“海马冷泉”由广州海洋地质调查局利用“海马”号首次在南海深海海底发现，是目前地球上已知规模最大的正处于活动期的深海冷泉系统。广州海洋地质调查局科技处副处长王伟巍介绍，“冷泉系统中通常伴随着天然气水合物（俗称可燃冰）的形成与发展。在‘海马冷泉’进行‘源火’采集，一是可以获取可燃冰这种清洁高效的能源进行引燃，契合‘绿色、共享、开放、廉洁’的办赛理念，二是在冷泉区域可以非常清晰地展示出可燃冰气液共存的状态，实现很好的科普。”

实施本次“源火”采集任务的科考船名为“海洋地质二号”。据广州海洋地质调查局方法所副所长陈宗恒介绍，该船是我国少见的兼具海洋科考和深海工程作业能力的一艘新型科考船，可独立完成环境评价、地质取样、物探调查等海洋科考调查作业，并具备承担海底电缆敷设、深水打捞、饱和潜水、风电工程勘察等海工作业的能力，为本次深海采火提供高效实施平台。

“海洋地质二号”科考船上的头号明星，得数4500米级“海马”号深海遥控潜水器（以下简称“海马”号），这也是本次潜入深海的“采火先锋”。本次任务充分发挥了“海马”号的两大能力：一是强大的功能扩展和集成能力，集成了“源火”采集装置，实现了不同类型的保压和耐压单元的集成和控制；二是精准精细的作业特点，能在复杂海底环境中找“针”——海底冷泉渗漏点，并通过机械手精细操作，实现“源火”采集。
