Ja ilmeisesti halvin kaasu pumpata on toistaiseksi se maakaasu?Maakaasun sekaan ei voida ilmaa työntää tai siitä saadaan 1200km pitkä merenalainen pommi. Teollisuudessa pienemmät putkistot täytettäisiin inertillä kaasulla(typellä) mutta tässä mittakaavassa sitä ei mistään ole yhtäkkiä saatavana ja vaikka olisikin niin kustannukset karkaisivat käsistä.
Typpeä jos vaikka 40 tonnin kuormissa lähdettäisiin ajamaan niin sitä menisi 10 bar paineella noihin putkiin 40 000 tonnia tai noin 1000 rekkalastillista. Ilman että se putki vuotaa. Sit jos se vuotaa niin sitä typpeä saattaisi mennä 1000 rekkalastillista tunnissa.
The day before, Danish and Swedish government agencies had registered unexplained submarine explosions. Russia, it’s becoming clear, is sabotaging its own pipelines – but the more lasting harm will be done to its Baltic Sea neighbors, who are now left with serious damage to their marine environment. But leaking pipelines don’t constitute military aggression. Causing environmental damage constitutes cunning gray-zone aggression – and like all gray-zone aggression, it’s extremely difficult to counter.
Scandinavian seismological experts and political leaders already agree that the explosions were a deliberate act. Who set them off? In theory, it might have been terrorists or other political extremists, but these lack the technical expertise to stage such sabotage; moreover, it is unclear why they would invest enormous effort and time into sabotage for little apparent gain.
Instead, the culprit appears to be the Russian government. With European countries cutting gas imports from Russia, the pipelines were not in full use anyway. (Germany has declined to certify Nord Stream 2.) What’s more, Moscow is desperately trying to frighten the West. On various occasions throughout September, Russian officials—up to and including Vladimir Putin—have invoked the nuclear specter in an effort to scare Western governments into ending their military support of Ukraine. But it hasn’t worked. Now Russia seems to be testing a new strategy: quietly causing harm to the Baltic Sea, a tiny ocean that is already extremely dirty. In addition to the damage done by commercial shipping, there’s the systematic flow of pollution from Kaliningrad.
For years, and despite pleas by Russia’s Baltic Sea neighbors, the Russian exclave was simply pumping its sewage into the sea. In 2016, a sewage plant co-financed by the Swedish International Development Agency became operational—but most of the Baltic Sea’s environmental-damage hotspots remain located off Kaliningrad and St. Petersburg. (Baltic states and Poland: you could be doing better too.)
And now, a gas leak. “The gas in the Nord Stream pipes is basically methane, which is a much stronger polluter than CO2, about 29 times stronger,” noted Jaakko Henttonen, a Finnish maritime-environment expert who has for years been involved in Baltic Sea states’ efforts to clean up their ocean. “According to the news so far, the leaks are significant.”
Damaging another country’s environment is easy, cheap, and can often be done without much risking one’s own habitat. With most of its coastline located elsewhere, Russia won’t suffer much if the Baltic Sea sustains environmental damage. China, meanwhile, has made harming other countries’ environment a veritable trademark. Its long-distance fishing fleet traverses the world’s oceans, parks itself in countries’ exclusive economic zones—where local fishermen earn their livelihoods—and casts their immense nets until the seas are empty. The vessel army then departs, having not only depleted the fish stocks but also harmed the seabed. And off the coast of Taiwan’s Matsu islands, Chinese excavators have for years been digging up sand. The practice presents the Taiwanese government with the constant headache trespassers that do harm but don’t engage in military aggression; Taipei has been forced to invest in an outsized coast-guard fleet. But in addition to being a nuisance, the dredgers cause harm to Taiwan’s maritime wildlife and its seabed. They often also manage to take the sand with them, a not-negligible benefit given that sand is becoming rarer, mostly as a result of China’s massive construction boom.
The Nord Stream 1 and Nord Stream 2 leaks are not yet a massive environmental disaster like the 1989 Exxon Valdez oil spill, which saw 11 million gallons of oil to leak into the waters off Alaska. But the leaks will create environmental harm, which Sweden, Denmark and any other good-willing Baltic Sea countries will have to tackle as best as they can. Like overfishing in other countries’ waters, causing gas leaks in their waters is not as dramatic as military aggression, but it causes harm all the same.
Ei pelkästään halvin vaan käytännössä ainoa mitä sinne putkeen voi määrissä pumpata. Mut voi olla että sinne ei edes pumpata mitään, tuollainen 1200km pitkä putki ei hetkessä tyhjeneJa ilmeisesti halvin kaasu pumpata on toistaiseksi se maakaasu?
Jos putki on kaput ja sitä ei voi korvata, niin miksi örkit eivät pistä sitä kiinni toisessa päässä ja anna meriveden täyttää putket?
Örkkien vai EUn rahoja?Putkissa on kiinni 20 miljardia euroa, vaikka kuinka on sota niin sitä ei kannata paskoa huvin vuoksi
Jos saksan päässä on hanat kiinni, niin vesi painaa kaasua 7 bar paineella putkeen ja mittari näyttää sitä. Taas pumppuaseman paine riippuu siitä että kuinka iso vuoto/pumpun tuotto milläkin paineella plus virtausvastus pumpun ja vuodon välissä.Tuskin Saksan päässä kaasuasemalla painetta mitataan 70 m syvyydessä. Eiköhän se tapahdu ihan maan pinnan läheisyydessä.
Yksinkertaistettuna örkit 51%, Saksa 31%, Hollanti 9% ja Ranska 9%.Örkkien vai EUn rahoja?
Ei kai sille mitään estettä ole. Sehän olisikin, jos ryssä pumppaisi raikasta ilmaa Karjalankannakselta putken täydeltä, jota juutit ja hurrit sitten siellä taivastelisivat.
Jos putket on kaput, niin sitä suuremmalla syyllä miksi sinne pitää ajaa maakaasua?
onko tuolla saarella jälkiä sukeltajista ja niiden jätteistä?
