    Kineska podvodna baza Had

    Kina planira izgradnju podvodne baze za neimenovane podmorske znastvene i obrambene operacije u Južnokineskom moru, centar koji bi mogao da postane prva kolonija vještačke inteligencije na Zemlji, kažu zvaničnici i znanstvenici uključeni u ovaj plan. Projekt, nazvan po Hadu, podzemnom bogu grčke mitologije, lansirala je Kineska akademija znanosti u Pekingu ovog mjeseca, nakon posjete podmorskom institutu u Sanji, Hanijska oblast. Predsjednik Ksi Jinginp je ohrabrio znanstvenike i inženjere da naprave nešto što dosad niko nije. Ideja za podvodnu ispostavu omiljena je znanstvenicima, inženjerima i piscima znanstvene fantastike već tisućama godina, dok je grčka legenda o Atlantidi inspirirala brojne priče o gradovima na morskom dnu. Had zona koja bi mogla da bude baza u nadubljem dijelu oceana, na dubini od 6 do 11 tisuća metara. Projekt košta 1,1 milijardu juana (160 miliona dolara). To je pola onoga što je utrošeno na FAST radio teleskop, najveći na svijetu, u jugozapadnoj Kini. Baš kao i svemirska stanica, podvodni kompleks će imati platformu za ukrcavanje. Projektni inženjeri će morati da osmisle koji će materijal koristiti i koji može da izdrži pritisak na tolikim dubinama. “Veoma je izazovno graditi koloniju kao da je na drugoj planeti za robote sa vještačkom inteligencijom”, rekao je jedan od znanstvenika na ovom projektu. “Tehnologija može da promijeni svijet.” Robotske podmornice će slati izvještaje, snimati podvodni svijet i sakupljati minerale. Kao samoodržavajuća laboratorija, stanica će analizirati uzorke i slati rezultate na kopno. Dok će baza zavisiti od kablova spojenih za brod ili platformu u pogledu struje i komunikacije, moćni “mozak” i senzori omogućiti će joj da obavlja misije. Južnokinesko more je vjerovatno najudaljeniji morski dio na svijetu, sa sedam teritorija oko kojih se bore neke države. Morsko dno ima ekstremne uvijete, visok pritisak, eroziju, potrese i nasilnu geologiju koja može da šteti strukturama. Ovo znači da će cijena ovog ambicioznog programa rasti. Doktor Du Kvinghaj, istraživač centra, kaže da je budžet 1,1 milijarda juana, ali da će možda biti malo. “Biti će teško sagraditi ovo, teže nego svemirsku stanicu. Nijedna zemlja ovo nije dosad uradila”, rekao je Du. Baza će biti izazov i za robote. Oko 99% dna mora, koji prekriva oko 70% Zemlje, nije istraženo. Profesor Jin Pin, sa Kineske akademije znanosti, kaže da će ova baza biti zahtjevna. Mora se istražiti dno. Potencijalna lokacija je Manila prolaz. “To je jedino mjesto u Južnokineskom moru koje je duboko 5 tisuća metara”. Manila prolaz je mjesto gde se Euroazija susreće sa Pacifikom. Nadublje dno jest 5,400 metara. To prestavlja problem zbog učestale vulkanske aktivnosti. Iako politički osjetljivo, nije nemoguće da će se ova baza sagraditi. Peking planira da sagradi i 20 plutajućih nuklearnih elektrana, a prva će biti gotova 2020.

    China Is Planning a Massive Sea Lab almost two miles underwater
    China is speeding up efforts to design and build a manned deep-sea platform to help it hunt for minerals in the South China Sea, one that may also serve a military purpose in the disputed waters. Such an oceanic “space station” would be located as much as 3,000 meters (9,800 feet) below the surface, according to a recent Science Ministry presentation viewed by Bloomberg. The project was mentioned in China’s current five-year economic plan released in March and ranked number two on a list of the top 100 science and technology priorities. Here is a translation of the March 2016 statement from the China Shipbuilding Industry Corporation. China Shipbuilding Industry Corporation is leading the deep sea platform project.

    March 25, 2016, the SASAC held a State Key Laboratory of Chinese Shipbuilding Industry Institute established the company seven hundred and two manned deep-sea equipment relying embodiment demonstration. Ministry of Science and basic research Sima Yan combined for Justice and feasibility studies to be requested, Key Laboratory enterprise hopes LEG implemented demonstration program in terms of objectives, research direction, organizational structure, operational mechanism. State Key Laboratory of manned deep-sea equipment has undertaken and completed the “dragon manned submersible research”, “deep space station key technologies”, “Self-propelled rescue bell” and more than 30 research projects, is the deep-sea manned State key laboratory of research equipment for the characteristics of enterprises, the laboratory will carry out research and development work in the overall design of manned equipment and integration technology, high voltage submersible deep structural design and safety assessment technology and deep space station key technologies. To achieve the “dream of a powerful ocean” provides important technical support, so that our deep-sea manned polyolefin material and equipment technology has reached world advanced level.

    “Having this kind of long-term inhabited station has not been attempted this deep, but it is certainly possible,” said Bryan Clark, a senior fellow at the Washington-based Center for Strategic and Budgetary Assessments. “Manned submersibles have gone to those depths for almost 50 years. The challenge is operating it for months at a time.” The U.S. Energy Information Administration says the South China Sea has proved and probable reserves of about 11 billion barrels of oil and 190 trillion cubic feet of natural gas. China Cnooc chairman estimated the South China Sea holds around 125 billion barrels of oil and 500 trillion cubic feet of natural gas. Modern nuclear attack submarines like the American Seawolf class are estimated to have a test depth of 490 m (1,600 ft), which would imply a collapse depth of 730 m (2,400 ft). Test depth is the maximum depth at which a submarine is permitted to operate under normal peacetime circumstances, and is tested during sea trials.

    The Crush depth of the Russian Alfa submarine is possibly over 1300 meters
    In June 2012, China’s manned submersible Jiaolong successfully completed its deepest test dive, to 7,020 meters in the Mariana Trench in the western Pacific Ocean. China now joins an exclusive club of countries that are capable of achieving human access to the deep sea. The other countries are the United States, Russia, France and Japan. The achievement will allow China to explore more than 99.8% of the ocean floor, Liu Cigui, director China’s State Oceanic Administration (SOA), told the media. Researchers at Shanghai Ocean University have also developed a submersible movable laboratory capable of operating at more than 13,000 feet underwater. Deepsea challenger has gone to the bottom of the ocean On March 26, 2012, James Cameron reached the bottom of the Challenger Deep, the deepest part of the Mariana Trench. The maximum depth recorded during this record-setting dive was 10,908 meters (35,787 ft).[42] Measured by Cameron, at the moment of touchdown, the depth was 10,898 m (35,756 ft). It was the fourth ever dive to the Challenger Deep and the second manned dive (with a maximum recorded depth slightly less than that of Trieste’s 1960 dive). It was the first solo dive and the first to spend a significant amount of time (three hours) exploring the bottom.

    Other Planned Ocean Bottom descents
    Several other manned expeditions are planned. These include:
    Triton Submarines, a Florida-based company that designs and manufactures private submarines, whose vehicle, Triton 36000/3, will carry a crew of three to the seabed in 120 minutes;
    Virgin Oceanic, sponsored by Richard Branson’s Virgin Group, is developing a submersible designed by Graham Hawkes, DeepFlight Challenger,with which the solo pilot will take 140 minutes to reach the seabed;
    DOER Marine, a San Francisco Bay Area based marine technology company established in 1992, that is developing a vehicle, Deepsearch (and Ocean Explorer HOV Unlimited), with some support from Google’s Eric Schmidt with which a crew of two or three will take 90 minutes to reach the seabed, as the program Deep Search

    DARPA upward falling payloads
    The DARPA Upward Falling Payload (UFP) program intends to put drones on the ocean floor. Cost and complexity limit the Navy to fewer weapons systems and platforms, causing strain on resources that must operate over vast maritime areas. Unmanned systems and sensors are commonly envisioned to fill coverage gaps and take action at a distance. However, power and logistics to deliver these systems over vast ocean areas limit their utility. The UFP concept centers on developing deployable, unmanned, nonlethal distributed systems that lie on the deep-ocean floor in special containers for years at a time. These deep-sea nodes could be remotely activated when needed and recalled to the surface. In other words, they “fall upward.” In today’s fiscally constrained environment, such a system of pre-positioned, deep-sea nodes could enable a full range of maritime mission sets that are more cost-effective than existing manned or long-range unmanned naval assets.

    Nearly 50% of the world’s oceans are deeper than 4 km, which provides vast areas for concealment and storage. As a consequence, the cost to retrieve UFP nodes is asymmetric with the likely cost to produce and distribute them to the seafloor. Concealment provided by the sea also provides the opportunity to quickly engage remote assets that may have been dormant and undetected for long periods of time, while its vastness allows simultaneous operation across great distances. Getting close to objects without warning, and instantiating distributed systems without delay, are key attributes of UFP capability. The UFP system is envisioned to consist of three key subsystems: The ‘payload’ which executes waterborne or airborne applications after being deployed to the surface; the UFP ‘riser’ which provides pressure tolerant encapsulation and launch of the payload; and the UFP communications, which triggers the UFP riser to launch.

    Jacques Cousteau had the Conshelf project. In 1962, the Conshelf I sat 10 meters (33 ft) under the surface of the Mediterranean off the coast of Marseilles. The small, cramped confine technically called the Diogenes was home to a pair of scientists for a week. It came equipped with a library, television, and radio, and was used as a research station to study marine life. Shortly after the success of the Conshelf I experiment, Conshelf II was launched. It came with even more fantastical amenities, such as a garage, an aquarium, and another research facility burrowed deeper into the sea, this time housing five people for a month. Finally, the most ambitious project was the Conshelf III, nested an incredible 100 meters (328 ft) beneath the water’s surface.
