Saturation diving is diving for periods long enough to bring all tissues into equilibrium with the partial pressures of the inert components of the breathing gas used. It is a diving mode that reduces the number of decompressions divers working at great depths must undergo by only decompressing divers once at the end of the diving operation, which may last days to weeks, having them remain under pressure for the whole period. A diver breathing pressurized gas accumulates dissolved inert gas used in the breathing mixture to dilute the oxygen to a non-toxic level in his or her tissues, which can cause decompression sickness ("the bends") if permitted to come out of solution within the body tissues; hence, returning to the surface safely requires lengthy decompression so that the inert gases

  • Sättigungstauchen ist ein Begriff aus dem Bereich der Berufstaucherei. Mit dem Sättigungstauchen wird dem Problem der erhöhten Dekompressionszeiten bei Tieftauchgängen begegnet. Dabei nutzt man die Tatsache, dass die Gasaufnahme des Organismus bei erhöhtem Druck irgendwann begrenzt ist. Nach einer bestimmten Zeit unter hohem Wasserdruck ist der Körper gesättigt, eine Verlängerung der Tauchzeit führt nicht zu einer noch längeren Dekompressionszeit. Da die Dekompressionszeit z. B. nach einem Tauchgang bis 200 m Tiefe bis zu sieben Tage betragen kann, kann sie nicht im Wasser verbracht werden. Dazu verwendet man heutzutage eine Überdruckkammer, die einen allmählichen Aufstieg um rund 30 m pro Tag simuliert. (de)
  • El buceo de saturación​ es un tipo de buceo que permite a los buzos permanecer a la presión de trabajo durante largos periodos de tiempo en cualquier medio hiperbárico. Cualquier obra de ingeniería en las profundidades del mar, se beneficia con este tipo de buceo, pues, los trabajadores tienen la posibilidad de vivir en el fondo del mar, es decir, no tienen la necesidad de salir cada día a la superficie para luego volver a entrar. Esto es una gran ventaja en términos de ahorro de tiempo y riesgo, pues el proceso de descompresión y compresión es largo y peligroso. Este tipo de buceo, es practicado por muy pocas personas debido a su complejidad y alto riesgo. (es)
  • La plongée en saturation (ou plongée à saturation) ou plongée à grande profondeur est une technique de plongée sous-marine réalisée avec une saturation préalable des gaz dans l'organisme des plongeurs. Ce type de plongée oblige les plongeurs à rester confinés dans des atmosphères sous pression (caisson hyperbare) pendant plusieurs jours. La plongée en saturation permet des plongées à plus de 100 mètres (record à 534 mètres). Elle est utilisée par les plongeurs professionnels intervenant sur les plates-formes pétrolières (plongeur offshore), la maintenance de barrage ou des plongeurs militaires intervenant sur les sauvetages de sous-marins.

  • Saturation diving is diving for periods long enough to bring all tissues into equilibrium with the partial pressures of the inert components of the breathing gas used. It is a diving mode that reduces the number of decompressions divers working at great depths must undergo by only decompressing divers once at the end of the diving operation, which may last days to weeks, having them remain under pressure for the whole period. A diver breathing pressurized gas accumulates dissolved inert gas used in the breathing mixture to dilute the oxygen to a non-toxic level in his or her tissues, which can cause decompression sickness ("the bends") if permitted to come out of solution within the body tissues; hence, returning to the surface safely requires lengthy decompression so that the inert gases can be eliminated via the lungs. Once the dissolved gases in a diver's tissues reach the saturation point, however, decompression time does not increase with further exposure, as no more inert gas is accumulated. Saturation diving takes advantage of this by having divers remain in that saturated state. When not in the water, the divers live in a sealed environment which maintains their pressurised state; this can be an ambient pressure underwater habitat or a saturation system at the surface, with transfer to and from the pressurised living quarters to the equivalent depth underwater via a closed, pressurised diving bell. This may be maintained for up to several weeks, and divers are decompressed to surface pressure only once, at the end of their tour of duty. By limiting the number of decompressions in this way, and using a conservative decompression schedule the risk of decompression sickness is significantly reduced, and the total time spent decompressing is minimised. Saturation divers typically breathe a helium–oxygen mixture to prevent nitrogen narcosis, and limit work of breathing, but at shallow depths saturation diving has been done on nitrox mixtures. Most of the physiological and medical aspects of diving to the same depths are much the same in saturation and bell-bounce ambient pressure diving, or are less of a problem, but there are medical and psychological effects of living under saturation for extended periods. Saturation diving is a specialized form of diving; of the 3,300 commercial divers employed in the United States in 2015, 336 were saturation divers. Special training and certification is required, as the activity is inherently hazardous, and a set of standard operating procedures, emergency procedures, and a range of specialised equipment is used to control the risk, that require consistently correct performance by all the members of an extended diving team. The combination of relatively large skilled personnel requirements, complex engineering, and bulky, heavy equipment required to support a saturation diving project make it an expensive diving mode, but it allows direct human intervention at places that would not otherwise be practicable, and where it is applied, it is generally more economically viable than other options, if such exist.

  • 飽和潜水(ほうわせんすい、Saturation diving)とは、深海の水圧に体をさらしつつ、超大深度への潜水を実現するための技術。これによって、100メートル以上の深度でも安全に長時間の活動ができるようになり、潜水病の危険も減った。最大で700メートル以上を潜ることも可能とされている。 (ja)
  • 포화잠수(飽和潛水, 영어: saturation diving)는 심해의 수압에 몸을 맡기면서, 초대형 깊이의 잠수를 실현하기 위한 기술이다. 이에 따라 100m 이상의 깊이에서도 안전하게 장시간 활동을 할 수 있게 되어, 잠수병의 위험이 줄었다. 예를 들어서 산소이외의 공기 성분으로 질소 대신 헬륨을 포함한 공기병을 이용해 호흡하는 기술이 있다. (ko)
  • Mättnadsdykning, dykteknik som används på stora djup med olika gasblandningar, som trimix eller heliox. Innebär att dykaren under lång tid lever under samma tryck som på det djup som dykeriarbetet gäller. Tekniken utvecklades för att kroppens vävnader vid dykning tar upp andningsgasen. Om uppstigningen sker för snabbt frigörs gas och formar små bubblor som snabbt kan bli så stora att de orsakar nervsmärtor eller stopp i blodcirkulationen. Det kallas för dykarsjuka och kan vara dödligt.För att undivika detta måste uppstigningen ske gradvis, så att kroppen hinner anpassa sig. Men ju djupare man dyker och ju längre tid man är nere, desto mer tid tar det för kroppen att anpassa sig. Ett halvtimmes dyk till 80 meter kräver drygt två timmar dekompression, ett entimmes dyk kräver tio timmar dekompression. Vid mättnadsdykning transporteras dykaren mellan och dykfartyget i en dykarklocka, och sover och äter i en tryckkammare på fartyget. På så vis behövs bara en enda, långsam, anpassning till normalt lufttryck efteråt. (sv)
