History of Diving 한국잠수응급구난망 김 희 덕

2 Introduction

3 Purpose - general history of the development of military diving operations Scope - outlines the hard work and dedication of a number of individuals who were pioneers in the development of diving technology

4 Role of the ROKN - Ship maintenance, search,
- UDT / Seal - Ship maintenance, search, - Rescue & salvage operation - Inspection & reparing naval vessels - Underwater construction - Location & recovering downed aircraft

5 Surface-Supplied Air Diving
표면공급 공기잠수

6 Introduction - Scyllis · Perscian King, Xerxes에 의해 고용됨 · B.C. 15C
· recover sunken treasure - Alexander the Great · B.C. 332 · remove obstacles in the Lebanon harbor

7 Breathing Tubes

8 Breathing Bag

9 Diving Bells (잠수 종) 15c ~18c For hours rather than minutes
Bell-shaped apparatus with the bottom open to the sea

10 1690, Edmund Halley - 60 ft, 4 divers, 1.5 hours  4 hours, 66ft

11 Diving Dress Design 1. Lethbridge’s Diving Dress

12 2. Deane’s Patented Diving Dress
- protection from the cold - helmet with view port - hose connections for surface supplied air 3. Siebe’s Improved Diving Dress - sealed the helmet to the dress at the collar - water proof suit - exhaust valve · MK V standard deep-sea diving dress

15 Caissons - Engineering technology

16 Physiological Discoveries 생리학적 발견
1. Caisson Disease (Decompression sickness)  감압병 - dizzy spell (일시적인 현기증) - Breathing difficulties ( 호흡곤란) - Sharp pain in the joint or abdomen (관절통 혹은 복통) - “bends”

17 1-1. Causes of DCS - 1878 - Paul Bert (French physiologist) - nitrogen into solution in the blood & tissues of the body (under pressure) - gas bubbles throughout the body (pressure released) - symptom 1-2. Prevention & Treatment of DCS - slowly return - recompression chamber (1879)

18 2. Inadequate Ventilation
- J. S Haldene (English physiologist) - CO2 accumulation  inadequate ventilation - standard supply rate of flow  1.5 fpm - pumps 3. Nitrogen Narcosis (질소마취) - 150 ft - euphoric & losing judgment - anesthetic properties - Heliox

19 Armored Diving Suits Atmospheric Diving Suit (ADS) = 대기압 잠수복  2000 ft

20 MK V Deep-sea Diving Dress

21 1905, MK V Diving Helmet 1916, Communication system Regulating valve Relief valve Exhaust valve (1927) 1927, Deep sea dress & umbilical MK 12 MK 21

22 Scuba Diving

23 S C U B A SCUBA : Self – Contained Underwater Breathing Apparatus
Open – Circuit Scuba Closed – Circuit Scuba Semiclosed – Circuit Scuba

24 Open-circuit Scuba Rouquayrol’s Demand Regulator
LePrieur’s Open-Circuit Scuba Design Cousteau ND Gagnan’s Aqua-Lung Impact of Scuba on Diving

25 Closed-Circuit Scuba Fleuss’ Closed-Circuit Scuba
Modern Closed-Circuit System

26 Hazards of Using Oxygen in Scuba
산소독성 1878, Paul Bert VENTIDC (CNS toxicity) Pulmonary toxicity

27 Mixed – Gas Diving

28 Introduction Breathing medium, consist of - - N2 & O2 proportions
- mixture of other inert gas (helium) with oxygen Special training, detailed planning, specialized & advanced equipment, extensive surface support personnel & facilities Qualified diver Two Categories - Nonsaturation diving without pressurized bell (max. 300ft) - saturation diving (150 fsw이상, extended bottom time)

29 Non-saturation Diving
1. Helium-Oxygen (Heliox) Diving - Physiological effects · high thermal conductivity of helium · high – pitched distortion or “Donald Duck” effect - MK V MOD 1 helmet 2. Hydrogen – Oxygen Diving - explosive character - 산소농도가 4% 이하면 폭발성이 없다 3. Modern surface – supplied Mixed – gas diving

30 Diving Bells 1. SDC(submersible decompression chamber)
- 2 men, steel, 2 opening hatches, - ventilate, gas & communication supply DDC(deck decompression chamber) - mate DDC-SDC - additional space, bunk, food & clothing 3. Saturation Diving - DDS(deep diving system)

31 Saturation Diving Extend actual working time at depth
Submarine rescue & salvage, sea bed implantments, construction scientific testing & observation Extensive bottom time

32 Saturation Diving-1 1. Advantage
- decompression is the most time consuming factor - 동일한 압력(수심)에 포화된 우리 인체는 해저체류 (잠수)시간에 관계없이 감압시간이 일정하다. - 200 fsw, 40 hrs  5 days at bottom pressure 2 days in decompression

33 Saturation Diving-2 2. Bond’s Saturation Theory
- 1957, NS Navy Diving Medical Officer Captain George F. Bond - The tissues of the body would eventually become saturated with inert gas if exposure time was long enough 3. Genesis Project - theory of saturation diving - animal & human experiments

34 Saturation Diving-3 4. Developmental Testing
- 1st practical open-sea demonstration Sep. 1962 by Edward A. Link & Capt. Jacques-Yves Cousteau - one man, He-O2 at 200fsw for 24hrs (Link) - two men, habitat, 33fsw for 169hrs (Cousteau) - Six men, N2-O2, 35fsw for 7 days (Cousteau) - 1964, Link & Lambertsen, 2-days, 2 men at 430fsw - seven men, 30 days at 36fsw & 90fsw with excursion dives to 330fsw

35 Saturation Diving-4 5. Sealab Program 1) Sealabs I and II
DEC. habitat 2) Sealab III - 600fsw, habitat, NEDU, 28 He-Ox, 825fsw( ) fsw, Sat depth  1,025fsw excursion diving(NEDU) - 31 ATA에서 작업가능하다는 것 증명

36 Deep Diving Systems(DDS)
Consist of - DDC(Deck decompression chamber) - PTC(Personal Transfer Capsule)

41 USS S-4 1927. Coast guard와 충돌 102fsw, 22시간후에 외부접촉 모두 사망(공기공급, 폭풍)
LT C.B. Momsen escape lung 발명 : 장교가 실험하여 성공

42 USS Squalus Mc Cann-Erickson Rescue chamber

- Deep Submergence Rewiew Group (DSRG) 구성 하여 Deep Submergence Systems Project  전 미해군내에 잠수 및 수중 활동에 관심 촉발 1972. DSRV (Deep Submergence Rescue Vehicle) fsw 까지 diving 가능 fsw 까지 rescue 가능

44 Salvage Diving (Salvage Operation)

45 History 1. 2차 세계대전 2. 월남전 3. 우리해군의 Salvage operation - 북한 반 잠수정 인양
