Underwater diving breathing gas supplied from the surface. US Navy Diver using Kirby Morgan Superlight 3. Surface supplied diving is diving using equipment supplied with breathing gas using a divers umbilical from the surface, either from the shore or from a diving support vessel, sometimes indirectly via a diving bell. This is different from scuba diving, where the divers breathing equipment is completely self contained and there is no link to the surface. The primary advantages of conventional surface supplied diving are lower risk of drowning and considerably larger breathing gas supply than scuba, allowing longer working periods and safer decompression. The copper helmeted free flow standard diving dress is the version which made commercial diving a viable occupation, and although still used in some regions, this heavy equipment has been superseded by lighter free flow helmets, and to a large extent, lightweight demand helmets, band masks and full face diving masks. Breathing gases used include air, heliox, nitrox and trimix. Saturation diving is a mode of surface supplied diving in which the divers live under pressure in a saturation system or underwater habitat and are decompressed only at the end of a tour of duty. Airline, or hookah diving, and compressor diving are lower technology variants also using a breathing air supply from the surface. VariationseditSeveral different arrangements exist for supplying breathing gas to divers from the surface Standard or Heavy gear The historical copper helmet, canvas suit and weighted boots. Scuba replacement A surface supplied arrangement where both the primary and reserve air supplies are from high pressure cylinders. The rest of the system is identical to the standard surface supply configuration, and the full umbilical system, bailout cylinder, communications and surface air panel are used. This is more portable than most compressors and is used by commercial diving contractors as a substitute for scuba with most of the advantages and disadvantages of a regular compressor fed surface supply. Hookah A basic form of surface supplied diving in which the air supply is via a single hose is often referred to as airline or Hookah occasionally Hooka diving. This often uses a standard scuba second stage as the delivery unit, but is also used with light full face masks. Bailout gas may be carried, but this is not always the case. Commercial diamond divers working in the shallow zone off the west coast of South Africa under the codes of practice of the Department of Minerals and Energy use half mask and demand valve hookah, and no bailout as standard practice. Their safety record is relatively poor. Snuba and SASUBA A system used to supply air from a cylinder mounted on a float to a recreational diver tethered by a short approximately 6m hose through a scuba regulator. Compressor diving An even more basic system is the Compressor diving arrangement used in the Philippines and Caribbean for fishing. This rudimentary and highly hazardous system uses a large number of small bore plastic tubes connected to a single compressor to supply a large number of divers simultaneously. The delivery end of the hose is unencumbered by any mechanism or mouthpiece, and is simply held by the divers teeth. Air supply is free flow and often unfiltered. AlternativeseditScuba, which is commonly used in recreational diving, is the main alternative to surface supplied diving equipment. Scuba is available in open circuit and rebreather configurations. Atmospheric diving suits such as the JIM suit and the Newtsuit isolate the occupant from the ambient pressure, but are bulky and extremely expensive. Manned and unmanned submersibles ROVs and AUVs have their applications, but lack the dexterity of a diver at present 2. Free diving, or breathhold diving, is extremely limited in duration and relatively high risk. Applicationedit. Free flow helmets are commonly used for diving in contaminated water. Surface supplied diving equipment and techniques are mainly used in professional diving or military diving due to the greater cost and complexity of owning and operating the equipment. This type of equipment is used in saturation diving, as the gas supply is relatively secure, and the diver can not bail out to the surface,7 and for diving in contaminated water, where the diver must be protected from the environment, and helmets are generally used for environmental isolation. There has been development of low cost airline systems for shallow recreational diving, where limited training is offset by physically limiting the depth accessible. Historyedit. 1. Deane brothers diving helmet, the first surface supplied diving dress equipment in the world. The first successful surface supplied diving dress equipment was produced by the brothers Charles and John Deane in the 1. Inspired by a fire accident he witnessed in a stable in England,1. Smoke Helmet to be used by firemen in smoke filled areas in 1. The apparatus comprised a copper helmet with an attached flexible collar and garment. A long leather hose attached to the rear of the helmet was to be used to supply air the original concept being that it would be pumped using a double bellows. A short pipe allowed breathed air to escape. The garment was constructed from leather or airtight cloth, secured by straps. The brothers had insufficient funds to build the equipment themselves, so they sold the patent to their employer, Edward Barnard. It was not until 1. German born British engineer Augustus Siebe. In 1. 82. 8 they decided to find another application for their device and converted it into a diving helmet. They marketed the helmet with a loosely attached diving suit so that a diver could perform salvage work but only in a full vertical position, otherwise water entered the suit. In 1. 82. 9 the Deane brothers sailed from Whitstable for trials of their new underwater apparatus, establishing the diving industry in the town. In 1. 83. 4 Charles used his diving helmet and suit in a successful attempt on the wreck of Royal George at Spithead, during which he recovered 2. In 1. 83. 6, John Deane recovered from the discovered Mary Rose shipwreck timbers, guns, longbows, and other items. How To Cite Literature And The Writing Process 10Th Edition. By 1. 83. 6 the Deane brothers had produced the worlds first diving manual, Method of Using Deanes Patent Diving Apparatus which explained in detail the workings of the apparatus and pump, plus safety precautions. In the 1. 83. 0s the Deane brothers asked Siebe to apply his skill to improve their underwater helmet design. Expanding on improvements already made by another engineer, George Edwards, Siebe produced his own design a helmet fitted to a full length watertight canvasdiving suit. The real success of the equipment was a valve in the helmet. Siebe introduced various modifications on his diving dress design to accommodate the requirements of the salvage team on the wreck of the HMS Royal George, including making the helmet be detachable from the corselet his improved design gave rise to the typical standard diving dress which revolutionised underwatercivil engineering, underwater salvage, commercial diving and naval diving.
