he uniquely designed and patented Cavimax Technology And Equipment is developed to clean underwater surfaces:\par
? Sea-craft, ships and freshwater vessels of different g1ass (tankers, dry cargo ships, yachts, cutters) ; ? Stationary hydro-technical structures (piers, moles, moorages); ? Sea platforms for various purposes (oil, gas extraction); ? Pipelines and other stationary submarine objects.\par
Underwater cleaning CAVIMAX TECHNOLOGY is based on the cavitation effect and is used for qualitative and high-speed destruction and removing of marine growth of any thickness (seaweed, shells, corals)', rust and peeling paint without damaging the hull and a protective coating. The surface can be cleaned Passive voice to bare metal with the help of the operating mode selection of the cavitating stream.\par
The CAVIMAX EQUIPMENT uses outboard sea or river water creating a speed cavitation max with microscopic Unusual word pair steam Possibly confused word of bubbles under 150-250 Bar with a capacity of 200 I/min (standard pumping plants). Upon contact with the surface being cleaned Passive voice, these bubbles implode. The result of the microscopic bubbles imploding is the destruction of marine growth, rust and, its removal from the work area. During this process, the working pressure reaches up to 10,000 Bar at the cleaned area.  1. Of the underwater accretion elimination technologies using the mechanic brushes (like "Sea Brush") and the Possibly miswritten world instrument series CAVIMAX.\par
voice. Out of the production of the PHOSMARINE company, being most wide-spread in the sphere of underwater cleansing, the Overused word "Sea Brush" mechanism with one disc brush weighs about 30 kg and has the productivity of 200-300m 2 /h while the Overused word mechanism with three-disc brushes "Brush Cart" weighs 170 kg and has the productivity of 1800 m 2 /h.\par
The Possibly miswritten word instrument of likewise productivity weighs 3 kg, correspondingly, whereas "Sea Brush" weighs 30 kg.\par
Divers, who cleanse the surfaces of the ships from accretion underwater, perform hard physical work, which requires oxygen consumption of 2. 5 -3. 0 liters/minute, the heart rate is 140-160 b/m. Such activities may be performed Passive voice in daylight only.\par
On the other hand, due to the low weight and safety of the Possibly miswritten word instrument, divers may perform their work with less physical effort at any time of the day.\par
It will take just one run of the instrument to cleanse the surface efficiently, unlike the brush devices, which require several Repetitive word for the same purpose.\par
One of the Overused word drawbacks of the brush devices is that they fail to function and shut down because of the water-plants rolled over the brush mechanism. Possibly miswritten word instruments Overused word cut all sorts of water-plants.\par
In Table \hyperref[tab_1]{1} below you can see the comparative productivity indexes of the two cleansing methods for the tanker with the capacity of 50 000 tons and the under-water area of 10 000 m 2 (the comparison is between the one-brush mechanism "Sea Brush" with the productivity of 300 m 2 /h and the one cavitation instrument). Possibly miswritten word instrument CaviMax.\par
The cavitation driver -"cavitator" is designed in such a way, that it is not damaged during work, as the supercavitation cavern is the working organ and consists of many steam-gas bubbles, which are formed Passive voice outside the cavitation cut.\par
The brushes require periodical Unusual word pair replacement due to wear ability. The cost of the brush depends on the construction and is in USD, as is shown in Table \hyperref[tab_2]{2}. 
\section[{Cleaning of Underwater Objects Technology}]{Cleaning of Underwater Objects Technology}\par
Global Journal of Researches in Engineering ( ) Volume XIx X Issue V Version I The comparative properties and productivity of various instruments are given Passive voice in Table \hyperref[tab_4]{4}. Table  {\ref 5}: Comparative data on the quality of the jobs performed Cost of the job 10-15 \$/m 2 "Sea Brush"\par
Cost of the job 1-5 \$/m 2 Possibly miswritten word instrument Damages costly protective paint-and-varnish, anticorrosion and antiaccretion coverings (on the weld seams) due to the contact of the instrument and the surface being cleansed.\par
Due to the selection of the cavitation flow parameters the accretion cleansing takes place without damaging the protective covering (In some cases cleansing may reach metal).\par
Requires periodical replacement of the mechanical cleansing elements (costly brushes and scrabers), which makes the cleansing process slower and costlier.\par
Does not require replacement of the working elements quant nozzles), cleansing may be performed in non-stop duration regimen.\par
Non-productive for thick accretion and some types of accretion (like major balanus and long water-plants).\par
Universal for accretion of any type and thickness.\par
Application in hard-to-reach spots is limited (vint and helm group, kingstone valves, grates, boxes etc.).\par
The instrument set allows efficient cleansing of all surfaces and hard-to-reach spots.\par
The use of hydrogears may cause leakage of oils and result in the environment contamination.\par
The technology is environment-friendly, as the overboard water is the single working material.\par
Possibly miswritten word instrument CaviMax.\par
Efficient, the frame surface is not damaged.

Global Journal of Researches in Engineering ( ) Volume XIx X Issue V Version I 2. Research and Development Enterprise BUSINESS PROPOSAL Our company has been operating in the service market for four years already. We design, test, and manufacture plants that are used to clean parts of submerged centrifugal pumps. Our equipment is unparalleled in Russia [1, 2] and the entire world. (The company has an industrial patent "Parts Cleaning Method and the Device Used for Such Cleaning"; the engineering documents and test certificates compliant with the All-Union Standards are also available).\par
The unit is designed based on the newest environmentally friendly technology unparalleled in the world with a special Overused word emphasis on today's efficiency and quality requirements.\par
The technology used in the proposed unit is hugely advantageous if compared to the more commonly known one that is often applied at repair facilities in Russia and in other countries of the world. The disadvantages of the conventional technology Possibly confused word include the following:\par
First of all, a commonly known technology Repetitive word involves corrosive and erosive wear of the parts' surface and its undesirable deformation. The parts cleaned in this way are, as a result, quickly discarded. Secondly, the amount of power consumed increases immensely when the parts are cleaned Passive voice. And thirdly, the cleaning efficiency with the technology is rather low.\par
The proposed Unusual word pair technology eliminates all of the listed drawbacks because the working substance here is water and supercavitation steam-and-gas air bubbles. The cleaning efficiency offered by this technology lies within the range of 50-60 thousand parts per month, provided that the plant is operated Passive voice in two shifts. The plant is a universal semiautomatic device that helps clean pump irrespective of their configuration. The cleaning is performed to 100\% at both the inner and outer surface of the Repetitive word with no further cleaning required. The flow diagram of the plant is shown Passive voise in Figure  {\ref 1}. 
\section[{?????????? ??????}]{?????????? ??????}\par
Cleaning device Parts are cleaned using the developed and patented environmentally friendly technology with the help of supercavitation flows that originate from the system of patented Repetitive word cavitation agents.\par
The Plant is unique in the way its environmental friendliness is achieved Passive voice. The whole principle is based on the recycled water that acts as a working cleaning agent, which, after it is used Passive voice, passes through the multi-stage filtration system specially designed for this plant, is then freed from solid impurities, oily additives and paraffin that are collected Passive voice in Overused word tanks, and finally recycled.        \begin{figure}[htbp]
