Sharma reported in med-December 2023 that the Mengxiang Drillship said to be capable of reaching 36,089 Feet to Seafloor? China has unveiled its first independently developed drilling vessel, named "Mengxiang" (Dream), which can drill the world's deepest depths. 

                                                                             China's Mengxiang to take the Seas Soon

The ship is purportedly equipped to reach a depth of 36,089 feet (11,000 meters). This depth surpasses the Mariana Trench, the deepest point in the world's oceans, which measures 36,200 feet (11,034 meters) according to the Encyclopedia Britannica, reported by the South China Morning Post. This drillship, hailed as the most sophisticated vessel for sub-seabed harvesting, is set to focus on extracting a distinctive resource known as "flammable ice," which is abundantly charged with methane gas.

80 billion tonnes of potential flammable ice

Gas hydrates, also known as methane hydrates, are ice-like compounds of water molecules containing trapped natural gas, primarily methane. Methane is a significant component of natural gas. Because the methane molecules are so closely structured within a crystalline structure of water molecules, they form a solid substance with a structure similar to ice. These hydrates are stable at specific temperature and pressure conditions found in deep-sea sediments and permafrost regions.

Enter the dream

With dimensions of 179.8 meters in length, 32.8 meters in width, and a weight of around 33,000 tonnes, the vessel is equipped with leading ocean drilling capabilities, reported CGTN. Its maiden voyage will take off in the next couple of days, according to the China Geological Survey (CGS) of the Ministry of Natural Resources. The ship is essential for helping China explore and use natural gas hydrates. This will make China more independent in getting energy and improve its ability to drill under the ocean. 
 
Gas hydrates have the potential to become a commercially viable energy source, although they are not considered environmentally friendly. This is particularly relevant as the world's largest importer of oil and gas, China, strengthens its capabilities in maritime activities, reported Xinhua.

Despite successful trial extractions in 2017 and 2020, concerns arise over the environmental impact of mining gas hydrates, such as the potential release of greenhouse gasses and threats to marine life.  Although considered a future fuel source, balancing energy needs with environmental stewardship remains critical in pursuing gas hydrate mining.

Gas hydrates a vast potential source of energy

China's ambition to extract gas hydrates from the South China Sea could also spark geopolitical tensions due to disputed sovereignty claims in the region.  The ship will use smart technology, like the digital twin system, to work better and monitor drilling operations. SCMP reported that China's state broadcaster CCTV emphasized the Dream’s record-breaking depth and advanced onboard laboratory facilities. 

The vessel boasts a sprawling laboratory covering 300 square meters, featuring nine sections dedicated to various scientific disciplines such as marine science, microorganisms, and rock magnetic field studies. With a weight of 33,000 tonnes and an endurance of 15,000 nautical miles, the Ministry of Natural Resources spearheaded the ship's construction in collaboration with over 150 companies and institutions. 

China estimates vast reserves of approximately 80 billion tonnes of potentially flammable ice in its waters.
