Joe Savoie
Hilbert Joseph Savoie Jr., known as Joe Savoie (25 January 1926, Pointe au Chen, Louisiana – 10 March 1996, Boutte, Louisiana), was a pioneering commercial diver and inventor of lightweight diving helmets, particularly the feature which allows the helmet to be sealed to the diver independently of the diving suit. After the Second World War he got into the newly established offshore oil industry in the Gulf of Mexico, Louisiana, and California, as a diver, and was known for his skills in oxy-arc cutting. He also got involved in the development of surface supplied diving helmets used in the industry. Savoie had no formal engineering education, but had a talent for practical innovation, combined with the experience of using a variety of equipment in the field, some of it of his own design. Family Wife Joyce, born Dronet, daughter Tonie and son Louis. Early life Savoie was brought up in south Louisiana in the Mississippi swamp-lands to a poor family, and grew up in an impoveri ...

Commercial Diver
Professional diving is underwater diving where the divers are paid for their work. The procedures are often regulated by legislation and codes of practice as it is an inherently hazardous occupation and the diver works as a member of a team. Due to the dangerous nature of some professional diving operations, specialized equipment such as an on-site hyperbaric chamber and diver-to-surface communication system is often required by law, and the mode of diving for some applications may be regulated. There are several branches of professional diving, the best known of which is probably commercial diving and its specialised applications, offshore diving, inshore civil engineering diving, marine salvage diving, hazmat diving, and ships husbandry diving. There are also applications in scientific research, marine archaeology, fishing and aquaculture, public service, law enforcement, military service and diver training. Any person wishing to become a professional diver normally require ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lightweight Demand Helmet
A diving helmet is a rigid head enclosure with a breathing gas supply used in underwater diving. They are worn mainly by professional divers engaged in surface-supplied diving, though some models can be used with scuba equipment. The upper part of the helmet, known colloquially as the ''hat'' or ''bonnet'', may be sealed directly to the diver using a ''neck dam'', connected to a diving suit by a lower part, known as a ''breastplate'', or ''corselet'', depending on regional language preferences. or simply rest on the diver's shoulders, with an open bottom, for shallow water use. The helmet isolates the diver's head from the water, allows the diver to see clearly underwater, provides the diver with breathing gas, protects the diver's head when doing heavy or dangerous work, and usually provides voice communications with the surface (and possibly other divers). If a helmeted diver becomes unconscious but is still breathing, most helmets will remain in place and continue to deliver ...

Mercury Spacesuit
The Mercury space suit (or Navy Mark IV) was a full-body, high-altitude pressure suit originally developed by the B.F. Goodrich Company and the U.S. Navy for pilots of high-altitude fighter aircraft. It is best known for its role as the spacesuit worn by the astronauts of the Project Mercury spaceflights. The MK IV Full Pressure Suit ensemble was also used extensively by the US Navy from about 1959 through the early 1970s in aircraft such as the F-4 Phantom, A-3/A-5/RA-5C Vigilante, and F-8 Crusader. Pre-Mercury development The suit was designed by Russell Colley (who designed and built the high-altitude pressure suit worn by aviator Wiley Post) as a means of providing an Earth-like atmosphere in the unpressurized high-altitude fighter jets developed by the U.S. Air Force and U.S. Navy after the Korean War. The Mark IV suit was first introduced in the late 1950s. Prior to the development of the Mark IV suit, the Navy developed different types of the Mark-series full-pr ...

Diving Safety
Diving safety is the aspect of underwater diving operations and activities concerned with the safety of the participants. The safety of underwater diving depends on four factors: the environment, the equipment, behaviour of the individual diver and performance of the dive team. The underwater environment can impose severe physical and psychological stress on a diver, and is mostly beyond the diver's control. Equipment is used to operate underwater for anything beyond very short periods, and the reliable function of some of the equipment is critical to even short-term survival. Other equipment allows the diver to operate in relative comfort and efficiency, or to remain healthy over the longer term. The performance of the individual diver depends on learned skills, many of which are not intuitive, and the performance of the team depends on competence, communication, attention and common goals. There is a large range of hazards to which the diver may be exposed. These each have assoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's corrosion resistance, resistance to corrosion results from the chromium, which forms a Passivation (chemistry), passive film that can protect the material and self-healing material, self-heal in the presence of oxygen. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into Sheet metal, sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products. The biological cleanability of stainless steel is superior to both alumi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fibreglass
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Visor
A visor (also spelled vizor) is a surface that protects the eyes, such as shading them from the sun or other bright light or protecting them from objects. Nowadays many visors are transparent, but before strong transparent substances such as polycarbonate were invented, visors were opaque like a mask * The part of a helmet in a suit of armor that protects the eyes. *A type of headgear consisting only of a visor and a band as a way to fasten it around the head. *Any such vertical surface on any hat or helmet. *Any such horizontal surface on any hat or helmet (called a ''peak'' in British English). *A device in an automobile that the driver or front passenger can lower over part of the windshield to block the sun (sun visor). Modern era Some modern devices called visors are similar, for example: *Visor (ice hockey) Types of modern transparent visors include: *The transparent or semi-transparent front part of a motorcycle crash helmet or police riotsquad helmets **Safety f ...

Diving Rebreather
A Diving rebreather is an underwater breathing apparatus that absorbs the carbon dioxide of a diver's exhaled breath to permit the rebreathing (recycling) of the substantially unused oxygen content, and unused inert content when present, of each breath. Oxygen is added to replenish the amount metabolised by the diver. This differs from open-circuit breathing apparatus, where the exhaled gas is discharged directly into the environment. The purpose is to extend the breathing endurance of a limited gas supply, and, for covert military use by frogmen or observation of underwater life, to eliminate the bubbles produced by an open circuit system. A diving rebreather is generally understood to be a portable unit carried by the user, and is therefore a type of self-contained underwater breathing apparatus (scuba). A semi-closed rebreather carried by the diver may also be known as a gas extender. The same technology on a submersible or surface installation is more likely to be referred ...

Heliox
Heliox is a breathing gas mixture of helium (He) and oxygen (O2). It is used as a medical treatment for patients with difficulty breathing because mixture generates less resistance than atmospheric air when passing through the airways of the lungs, and thus requires less effort by a patient to breathe in and out of the lungs. It is also used as a breathing gas diluent for deep ambient pressure diving as it is not narcotic at high pressure, and for its low work of breathing. Heliox has been used medically since the 1930s, and although the medical community adopted it initially to alleviate symptoms of upper airway obstruction, its range of medical uses has since expanded greatly, mostly because of the low density of the gas. Heliox is also used in saturation diving and sometimes during the deep phase of technical dives. Medical uses In medicine heliox may refer to a mixture of 21% O2 (the same as air) and 79% He, although other combinations are available (70/30 and 60/40). Hel ...

Breathing Gas
A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common and only natural breathing gas, but other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, high-altitude mountaineering, high-flying aircraft, submarines, space suits, spacecraft, medical life support and first aid equipment, and anaesthetic machines. Oxygen is the essential component for any breathing gas, at a partial pressure of between roughly 0.16 and 1.60 bar at the ambient pressure. The oxygen is usually the only metabolically active component unless the gas is an anaesthetic mixture. Some of the oxygen in the breathing gas is consumed by the metabolic processes, and the inert components are unchanged, and serve mainly to dilute the oxygen to an appropriate concentration, and are therefore also known as diluent gases. Most bre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Factors In Diving Equipment Design
Human factors in diving equipment design are the influence of the interaction between the diver and the equipment on the design of the equipment. The underwater diver relies on various items of diving and support equipment to stay alive, in reasonable comfort and to perform the planned tasks during a dive. The design of the equipment can strongly influence its effectiveness in performing the desired functions. Divers vary considerably in anthropometric dimensions, physical strength, joint flexibility, etc. Diving equipment should allow a full range of function as reasonably practicable and should be matched to the diver, the environment and the task. The interface between equipment and diver can strongly influence functionality. Diving support equipment is usually shared by a wide range of divers and must work for them all. Where correct operation and use of equipment is critical to diver safety, it is desirable that different makes and models should work similarly, to facilit ...
