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 diver's teeth. Air supply is free flow and often unfiltered, and varies with depth and number of divers drawing off the system, with greater flow going to divers with a shorter hose and at shallower depth. A kink or restriction in a hose can cut off a diver's air supply without warning.<sup id="cite_ref-Into_the_blue_9-0" class="reference"><a href="#cite_note-Into_the_blue-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup></li></ul> <div class="mw-heading mw-heading4"><h4 id="Bell_bounce_diving">Bell bounce diving</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Surface-supplied_diving&action=edit&section=6" title="Edit section: Bell bounce diving"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">See also: <a href="/wiki/Surface-supplied_diving_skills#Bell_bounce_diving" title="Surface-supplied diving skills">Surface-supplied diving skills § Bell bounce diving</a></div> <p>Bell bounce diving, also known as transfer under pressure diving, is where the divers are transported vertically through the water in a <a href="/wiki/Closed_bell" class="mw-redirect" title="Closed bell">closed bell</a> and <a href="/wiki/Transfer_under_pressure" class="mw-redirect" title="Transfer under pressure">transferred under pressure</a> into a surface <a href="/wiki/Deck_decompression_chamber" class="mw-redirect" title="Deck decompression chamber">decompression chamber</a> for decompression, or decompressed in the bell.

The apparatus comprised a copper helmet with an attached flexible collar and jacket. 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 continuous airflow passed through the helmet, and the user breathed from it and exhaled back into it. A short pipe allowed excess air to escape. The garment was constructed from leather or airtight cloth, secured by straps.<sup id="cite_ref-Deane_helmet_16-0" class="reference"><a href="#cite_note-Deane_helmet-16"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup> </p><p>The brothers had insufficient funds to build the equipment themselves, so they sold the patent to their employer, Edward Barnard.

Thus, the surface-supplied diver is less likely to have an "out-of-air" emergency than a scuba diver using a single gas supply, as there are normally two alternative breathing gas sources available.

It is either not taken into the water during the dive, such as the gas panel and compressor, or is not integral to the actual diving, being there to make the dive easier or safer, such as a surface decompression chamber. Some equipment, like a <a href="/wiki/Diving_stage" class="mw-redirect" title="Diving stage">diving stage</a>, is not easily categorised as diving or support equipment, and may be considered as either. </p><p>Surface-supplied diving equipment is required for a large proportion of the commercial diving operations conducted in many countries, either by direct legislation, or by authorised codes of practice, as in the case of IMCA operations.<sup id="cite_ref-IMCACoP_23-0" class="reference"><a href="#cite_note-IMCACoP-23"><span class="cite-bracket">[</span>23<span class="cite-bracket">]</span></a></sup> Surface-supplied equipment is also required under the <a href="/wiki/United_States_Navy" title="United States Navy">US Navy</a> operational guidance for diving in harsh <a href="/wiki/Water_pollution" title="Water pollution">contaminated environments</a> which was drawn up by the <a href="/wiki/United_States_Navy_Experimental_Diving_Unit" title="United States Navy Experimental Diving Unit">Navy Experimental Diving Unit</a>.<sup id="cite_ref-USNcontam_24-0" class="reference"><a href="#cite_note-USNcontam-24"><span class="cite-bracket">[</span>24<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Breathing_apparatus">Breathing apparatus</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Surface-supplied_diving&action=edit&section=12" title="Edit section: Breathing apparatus"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The definitive equipment for surface-supplied diving is the breathing apparatus which is supplied with primary breathing gas from the surface via a hose, which is usually part of a diver's umbilical connecting the surface supply systems with the diver, sometimes directly, otherwise via a bell umbilical and bell panel. </p> <div class="mw-heading mw-heading4"><h4 id="Helmets">Helmets</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Surface-supplied_diving&action=edit&section=13" title="Edit section: Helmets"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Diving_helmet" title="Diving helmet">diving helmet</a></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Diver_Rose_Bay_1938_SLNSW_FL19114501.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/1/18/Diver_Rose_Bay_1938_SLNSW_FL19114501.jpg/220px-Diver_Rose_Bay_1938_SLNSW_FL19114501.jpg" decoding="async" width="220" height="224" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/1/18/Diver_Rose_Bay_1938_SLNSW_FL19114501.jpg/330px-Diver_Rose_Bay_1938_SLNSW_FL19114501.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/1/18/Diver_Rose_Bay_1938_SLNSW_FL19114501.jpg/440px-Diver_Rose_Bay_1938_SLNSW_FL19114501.jpg 2x" data-file-width="2941" data-file-height="3000" /></a><figcaption>Diver at Rose Bay, Sydney Harbour, 1938</figcaption></figure> <p><a href="/wiki/Lightweight_demand_helmet" class="mw-redirect" title="Lightweight demand helmet">Lightweight demand helmets</a> are rigid structures which fully enclose the head of the diver and supply breathing gas "on demand".

Mechanical work of breathing is minimal, but flow rate must be high if the diver works hard, and this is noisy, affecting communications and requiring hearing protection to avoid damage to the ears. This type of helmet is popular where divers have to work hard in relatively shallow water for long periods. It is also useful when diving in contaminated environments, where the helmet is sealed onto a dry suit, and the entire system is kept at a slight positive pressure by adjusting the back-pressure of the exhaust valve, to ensure that there is no leakage into the helmet. This type of helmet is often large in volume, and if it is attached to the suit, it does not move with the head. The diver must move their body to face anything they want to see.

Bulk cylinders are also quiet in operation compared to a low-pressure compressor, but have the obvious limitation of amount of gas available. The usual configurations for surface-supplied bulk gas storage are large single cylinders of around 50 litres water capacity, often referred to as "J"s or "bombs", "<a href="/wiki/Gas_storage_quad" class="mw-redirect" title="Gas storage quad">quads</a>", which are a group (sometimes, but not necessarily four in number) of similar cylinders mounted on a frame and connected together to a common supply fitting, and "kellys" which are a group of "tubes" (long large volume pressure vessels) usually mounted in a <a href="/wiki/Intermodal_container" title="Intermodal container">container frame</a>, and usually connected together to a common connection fitting.<sup id="cite_ref-IMCAD043_46-0" class="reference"><a href="#cite_note-IMCAD043-46"><span class="cite-bracket">[</span>46<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading4"><h4 id="Bailout_gas_supply">Bailout gas supply</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Surface-supplied_diving&action=edit&section=25" title="Edit section: Bailout gas supply"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Bailout_cylinder" class="mw-redirect" title="Bailout cylinder">Bailout cylinder</a></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Bailout_block_on_a_KM18_band_mask_PA268043.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/a/a6/Bailout_block_on_a_KM18_band_mask_PA268043.jpg/220px-Bailout_block_on_a_KM18_band_mask_PA268043.jpg" decoding="async" width="220" height="165" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/a/a6/Bailout_block_on_a_KM18_band_mask_PA268043.jpg/330px-Bailout_block_on_a_KM18_band_mask_PA268043.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/a/a6/Bailout_block_on_a_KM18_band_mask_PA268043.jpg/440px-Bailout_block_on_a_KM18_band_mask_PA268043.jpg 2x" data-file-width="3648" data-file-height="2736" /></a><figcaption>The bailout block on a KM18 band mask, showing the bailout valve (upper left), the non-return valve for main air supply (lower left), and the free-flow valve (right)</figcaption></figure> <p>Bailout gas is usually carried by the diver in a scuba cylinder, mounted on the back of the harness in the same position as is used with recreational scuba. The size of the cylinder will depend on operational variables. There should be sufficient gas to enable the diver to reach a place of safety on the bailout gas in an emergency. For surface oriented dives, this may require gas for decompression, and bailout sets generally start at about 7 litres internal capacity and can be larger.<sup id="cite_ref-inshore_47-0" class="reference"><a href="#cite_note-inshore-47"><span class="cite-bracket">[</span>47<span class="cite-bracket">]</span></a></sup> </p><p>Bell diving bailout options: For bell dives there is no requirement for decompression gas, as the bell itself carries bailout gas. However at extreme depths the diver will use gas fast, and there have been cases where twin 10 litre 300 bar sets were required to supply sufficient gas. Another option which has been used for extreme depth is a rebreather bailout set. A limitation for this service is that the diver must be able to get in and out of the bell while wearing the bailout equipment.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources. (September 2016)">citation needed</span></a></i>]</sup> </p><p>Mounting options: The bailout cylinder may be mounted with the valve at the top or at the bottom, depending on local codes of practice. A generally used arrangement is to mount the cylinder with the valve up, as this is better protected while kitting up, and the cylinder valve is left fully open while the diver is in the water. This means that the regulator and supply hose to the bailout block will be pressurised during the dive, and ready for immediate use by opening the bailout valve on the harness or helmet.<sup id="cite_ref-inshore_47-1" class="reference"><a href="#cite_note-inshore-47"><span class="cite-bracket">[</span>47<span class="cite-bracket">]</span></a></sup> </p><p>The bailout block is a small manifold fitted either to the harness where it is in a convenient but protected position, commonly on the right side on the waist strap, or on the helmet, also usually on the right side of the temple, with the valve knob to the side to distinguish it from the free-flow or defogging valve which is commonly to the front. The bailout block has a connection for the main gas supply from the umbilical through a non-return valve. This route can not be closed and supplies the helmet demand valve and free flow valve under normal circumstances. The bailout gas from the back mounted cylinder passes through a conventional scuba first stage at the cylinder valve, to the bailout block, where it is normally isolated by the bailout valve. When the diver needs to switch over to bailout gas he simply opens the bailout valve and the gas is supplied to the helmet or mask. As the valve is normally closed, a leak in the first stage regulator seat will cause the interstage pressure to rise, and unless an overpressure relief valve is fitted to the first stage the hose may burst. Aftermarket overpressure valves are available which can be fitted into a standard low-pressure port of most first stages.<sup id="cite_ref-KM_OPRV_48-0" class="reference"><a href="#cite_note-KM_OPRV-48"><span class="cite-bracket">[</span>48<span class="cite-bracket">]</span></a></sup> </p><p>Bailout supply pressure options: If the interstage pressure for the bailout regulator is lower than the main supply pressure, the main supply will override the bailout gas, and continue to flow. This can be a problem if the diver switches to bailout because main supply is contaminated. If on the other hand, bailout pressure is higher than main supply pressure, the bailout gas will override the main gas supply if the valve is opened. This will result in the bailout gas being used up if the valve leaks. The diver should periodically check that bailout pressure is still sufficient for the rest of the dive, and abort the dive if it is not. For this reason the bailout regulator must be fitted with a submersible pressure gauge to which the diver can refer to check the pressure. This is usually clipped off or tucked into the harness on the left side, where it can be easily reached to read, but is unlikely to snag on anything.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

The diving contractor provides the diving and support equipment and sets it up on site, usually at a place provided for the purpose by the client, or on a diving support vessel. Two types of diving spread are in common use: Air spreads for surface oriented diving operations, where the divers are deployed from normal atmospheric pressure, and decompressed back to atmospheric pressure at the end of the dive, either in-water, or in a chamber for surface decompression, using compressed air as the primary breathing gas, and saturation spreads, where divers are deployed under pressure from the saturation accommodation via a closed diving bell to the underwater worksite, and returned under pressure in the bell to the saturation accommodation system, usually breathing a helium based gas mixture. At the end of their contract the divers are decompressed to surface pressure. The process of selecting, transporting, setting up and testing the equipment is the mobilisation stage of the project, and the demobilisation involves dismantling, transportation and return to storage of the spread components.<sup id="cite_ref-Bluestream_53-0" class="reference"><a href="#cite_note-Bluestream-53"><span class="cite-bracket">[</span>53<span class="cite-bracket">]</span></a></sup> </p><p>Surface oriented mixed gas diving spreads may also be used, but are less common, and are likely to be associated with projects which are too deep for air but require only a short working time at depth. </p> <div class="mw-heading mw-heading3"><h3 id="Air_spread">Air spread</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Surface-supplied_diving&action=edit&section=43" title="Edit section: Air spread"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>An air spread will include the breathing air supply equipment, and often a deck decompression chamber.

There are a number of components which must be connected in the correct order, with checks at various stages to ensure that there are no leaks and everything functions correctly. Most diving contractors will have comprehensive checklists that are used to ensure that the equipment is connected in the appropriate sequence and all checks are done. Some checks are critical to the safety of the diver. The compressor must be set up so that it gets uncontaminated air to the intake. Filters should be checked in case they need to be changed. Air supply hoses will be connected to the air panel and checked for leaks, umbilicals connected to the panels and helmets, and the communications equipment connected and tested. Before the umbilical is connected to the helmet or full face mask, the umbilical should be blown through to ensure there is no dirt inside, and the non return valve on the bailout block must be given a function test. This is important, as it is there to prevent backflow of air up the umbilical if the line is cut, and if it fails the diver may suffer a helmet squeeze, or a neck dam flood.<sup id="cite_ref-CDM_9_26-3" class="reference"><a href="#cite_note-CDM_9-26"><span class="cite-bracket">[</span>26<span class="cite-bracket">]</span></a></sup> </p><p>Compared to scuba diving, dressing the diver in<sup id="cite_ref-54" class="reference"><a href="#cite_note-54"><span class="cite-bracket">[</span>a<span class="cite-bracket">]</span></a></sup> is a relatively laborious process, as the equipment is bulky and fairly heavy, and several components are connected together by hoses.

For this reason a stand by diver should be one of the best divers on the team regarding diving skills and strength, but does not have to be expert at the work skills for the specific job. When deployed, the standby diver will normally follow the umbilical of the diver who is in trouble, as unless it has been severed, it will reliably lead to the correct diver.

In bell diving, the bellman is the primary standby diver, and may have to recover a distressed diver to the bell and give first aid if necessary and possible.
