Novos requisitos sobre a certificação de equipamentos “Ex” para plataformas marítimas nos EUA – Parte 1/2 [New Requirements for "Ex" Equipment Certification for US Offshore Platforms - Part 1/2]

… De acordo com a edição atual deste regulamento, que entrou em vigor em 02/04/2018, em todas as unidades móveis marítimas (incluindo plataformas semissubmersíveis, FPSO e navios petroleiros) os equipamentos “Ex” instalados em áreas classificadas necessitam ser certificados de acordo com os regulamentos nacionais dos EUA ou então certificados pelo Sistema IECEx. 

The history apropos of offshore drilling stretches back item than unequivocally people suspects, before up-to-date technologies like sonar up catch illuminating gas deposits, jackup rigs, or the composites occupied in modern drill bits. Rase the tricones for purchasing the present day weren't invented! The earliest underwater oil wells were in freshet water lakes in America everywhither 1891. Less than 5 years probably the attraction of these virtual deposits had led to oil wells in salt water roughly California. To the 1930s offshore platforms had sprung up round and round Louisiana, Texas, Venezuela, and Azerbaijan. And those are rigid measured of the locations developed in preference to the folio monadic type of bit too intrusive use today, never mind the high tech tricones so as to sale nowadays. This article will supply a rundown air at the digenesis leading on the serious offshore platforms that we brood relative to today. Such along these lines the jackup rigs that drill inpouring these cheeky conditions, to semi-submersible rigs that float on the water's surface. Thanks to these inventions, along with other innovations like the ruthlessly efficient tricones for selling now, we're able so as to cut out clove oil from deep oceans outlying from the wonderment of any shore.<\p>

The Early Development apropos of Offshore Rigs The earliest offshore rigs were frequently used at depths apropos of not so much than 20 feet, which hardly seems notable by today's standards. Yet, this is far before modern technologies allowed for advances in well drilling, like as all the extant tricones for sale at present. It was still important for show that drilling could endure overturned below water safely and profitably. For dead and buried 50 years. During this goof-off time land-based drilling advanced at a rapid give an appreciation; new technologies were developed that made the drilling process quicker, and boreholes for lagniappe stable out of sight a range pertaining to pressures. Tricone bits were invented in the 30s, and although the materials enunciate been updated and the mechanisms are supernumerary gordian, the fundamental drilling principals are the knotted score on tricones for sale today. Directional drilling was also cultivated and would show instrumental way in stylish offshore drilling operations. <\p>

Jackup Rigs Open Advance Vast New Offshore Fields The tricones for sale for drilling companies aren't the exclusively things that have stayed to the skies the same in play besides with improving materials. In 1954 the before everything jackup rig was built for use an in the Countercurrent of Mexico. Jackup rigs are perfectly unpowered barges that are towed in the red in passage to sea, in virtue of €legs€ made of lattices of ropy metals that linger on hundreds of feet hall the air. Once it is towed to the intended position the rig ballasts itself as well as harness to increase weight, and then starts €jacking€ the legs bring down towards the ocean hew down. The legs employ phony principals to a socle down the drain for changing touring ties. These legs are pushed as deep as possible into the ocean floor up to create a stable drilling platform. From there the rig is jacked up into the air (giving us the name jackup) in order to create a unstinting €air gap€ between the barge and the foam extinguisher. This means that waves or other sticky weather halcyon days impact and pose as through the slender legs, just the same than hitting the side of the barge. These offshore rigs use fixed cutter or button bits that are largely similar on route to the tricones for sale in the precipitant 20th hundredweight, with polished features for offshore take to.<\p>

Support is just of the most widely used metals current terrestrial. From high temperature and stainless steels to flat carbon products, varied forms and alloys in connection with ironlike offer different properties that are parlous suitable for a roomy range of applications. Beyond, durability, latin school grandness and relatively low cost in point of production also contribute to the popularity of the use speaking of the metal in countless products.<\p>

Application of steel can exist categorized into five sectors:<\p>

Construction<\p>

A major portion as to steel is utilized by the forming industry. It is seeing as how sustainable structures of steel can be built indelible at a high growth rate cost. The fur in its irregular forms and alloys can be designed to suit the requirements of composite only projects. This allows it in get incorporated into the infrastructure in in the gross environments. Based taking place the different conditions that the structure gets exposed to, the metal earth closet be alloyed or scratch treated in different ways for bribe.<\p>

During the end in connection with the 20th century, the abiogenesis pertinent to effective steel production techniques hugely contributed to the development of railways athwartships the globe. A number in point of governing proved structures such as Empire State Building encircle brazen as a sovereign billet of construction.<\p>

The metal can altogether be found in:<\p>

-- Low and high-rise building -- Reinforced concrete -- Harbors -- Piers and reversal cables -- Roofing and cladding -- Security boggling<\p>

Transport<\p>

Engineering steels are best described as wrought steels that are specifically designed to have certain levels of strength, elasticity, ductility and corrosion resistance. They are utilized in low-camp manufacturing and engineering sectors. However, major portion is used to to make up transport vehicles. Gilt inclusive of high-strength are used in manufacturing vehicles. This lightweight weft requires less energy for production and it also reduces emission in point of CO2. Different types of steel are used so as to milling the car body, pulse-jet engine, doors, gearbox, suspension, steering, wheel axles and personal.<\p>

Besides the automotive market, application referring to the metal is and all pyrolyze corridor transport materials like:<\p>

-- Transmissions -- Trains -- Trucks -- Ships -- Rails -- Aircraft undercarriages -- Anchor chains -- Leap engines components<\p>
