Since the inception of the shipping industry, the leakage in hatch covers results in serious and massive commercial destruction. The claims made by the wet cargo and shipping industry has perplexed the customers, ship owners, cargo handling companies, their managers and insurance companies. No matter whatever they do or how hard they try, the manual methods and testing techniques, failed to provide complete protection and security against the leaks and cracks which results in the destruction of valuable cargo and goods on board. This often results in the shipping industry paying the millions of dollars in lieu of insurance claims and law suits by the goods companies for the destruction of their cargo due to water. In addition to this, the delays in the shipments, schedule disruptions and sometimes even sinking of ships, are the other factors that cause significant loss to the industry. Sometimes the ships have been even left in the ocean all alone and the crew has to board another ship due to life threatening leaks or cracks in the ship.
All this has resulted in different attempts to control these outcomes due to leakages or cracks in the ships. This lead to the invention and the use of hatch cover ultrasonic tightness testing for checking and verifying the integrity of the hatch covers. This technique has yielded fabulous and promising results. With the invention and formulation of modern techniques and gadgets for this purpose, the ultrasonic testing has gained control over much of the problems associated with hatch leakage at less amount of cost. The outward shinning and dazzling body of the ship, no matter how heavy and bright it might look, it is bound to get weaken from the site where it is connected with the other moving parts inside the ship. With the passage of time, the doors, windows, hatch covers, etc, starting developing holes or cracks, which can allow the water seepage in the lower parts of the ship. Due to extensive contact with water and humidity, the protective layering provided by the manufacturers of the ship starts to erode allowing the metal to be directly exposed to the water and humidity.
Therefore, it is a vital duty of the ship manager to maintain the ship and to keep check and balance of the areas which are getting affected by corrosion. It is his responsibility to keep every area of the ship well maintained and well checked for any kind of damages or cracks on regular basis. For this purpose, checking the Tightness of hatch with Ultrasound provides reliable and credible outcomes in less time and spending less amount of energy. The ultrasound scan of the whole ship can be conducted in few hours or if the ship is too big or damaged, it takes one or two days. It does not need large number of men to conduct a test. A single individual can easily conduct it. This saves a lot of money to the shipping company, which might be required otherwise.
The business world has to face many different types of problems on daily basis and leaks or cracks are one of them. Leaks and cracks wherever become visible can be a cause of terrible and most unexpected accidents. The shipping company has been a biggest target of this catastrophic problem since its inception. This is due to the nature of the shipping business. The ships are in constant contact with water and humid air. The metal body of the ship is bound to be vulnerable to leaks and cracks after some time when its protective coating wears off. The leakage can cause major setback to the shipping business. The ship owners can take control of it by checking Tightness of hatch with Ultrasound but when they are ignorant of it or does not do it on regular basis, the leaking in the hatch covers is the result.
The leaking of hatch covers is one of the major woes of the shipping industry and there is no way to stop or prevent them. The damage or loss they can do to the ship is incomprehensible. One of the main reason due to which the damage is done to the ship is the scraping and scratching caused by the uplifting and lowering of the heavy metal chains, used for lifting and lowering the cargo containers. As these chains rub against the body of the ship it scraps away the protective covering on the body of the ship, making it in naked contact to the water and humid air.
The exposure of the naked metal to the humidity in air and also to the water of the ocean or sea, immediately spur out rust which starts spreading and reach out to even unexpected places. The rust is an enemy of the metal, no matter how thick the metal sheet is. it starts prevailing and penetrating deep into the metal until it eats it all away like a mouse. In case of thick metal sheet, it may take longer for the hole or crack to appear but it will ultimately appear if not taken proper precautions or detected on time. Once the holes or cracks get developed in the metal sheets of the hatch covers, nothing can be done but just to treat them in proper manner.
There are many different ways and methods of treating this problem which depends on the size of the damage done to the hatch covers. But still these methods cannot be properly implemented and applied until and unless Hatch Cover Ultrasonic Tightness Testing is not conducted. On time implementation of the testing technique and the proper use of the ultrasonic testing device can save you from many big problems in the future. The ultrasonic testing of the ships on regular basis can help you to detect small holes or cracks on time before they get too big. This enables you to get them repaired by spending less amount of money and making fewer efforts. The ship will take less time to repair and will be back to work in your fleet with same strength.
Level measurement of different liquids used on industrial scale is very important for the maintenance of quality standards and to ensure safety and protection of the employees and the industry as a whole. The liquid level indicator has many diverse uses and is used for wide range of different functions. There are many different types of application in the industry in which the measurement of the liquid level is required. It could be used to measure the level of liquids or solids as well. Some of the typical uses of liquid level measurement indicators are for waste-water management and treatment system, measurement of bore hole or well level, measuring liquid level in tanks, vessels or containers etc. some of the common usage of solid level measurements could be for dust collectors, pneumatic conveying receivers etc.
The liquid level measurements have been divided into two broad categories; point level measurement and continuous level measurements. The point level measurement is used to detect and control the liquid measurement at some point in the container or vessel. The continuous level measurement keeps a check on the level of the liquid all the time through a level transmitter or a transducer. The output provided by the level transmitters is of 4 to 20 signals, often. This is proportional to the height of the medium or liquid. Mostly, the output of the continuous level is used for controlling the pump or valve that is controlling the level of the medium or liquid, continuously and consistently.
This article will provide a brief overview of some of the popular continuous level measurement techniques which would include; hydrostatic pressure, ultrasonic and radar.
1. Hydrostatic pressure technique: it makes use of the differential pressure sensor and is commonly used for sensing the liquids in the huge tanks or liquid reservoirs. The differential pressure sensor in the device measures two pressure inputs; a high pressure and a low pressure port. It provides the difference of the total tank pressure and the head pressure of the liquid in the tank.
2. Ultrasonic level indicator: these sensors are used where non contact level sensing is required. The ultrasound waves are transmitted into the material container. The waves reflect back and are gathered by the transmitter. The level of the medium inside the container is measured by calculating the time the ultra sound waves take to travel from the sensor to the material and the reflection of the echo sound back to the sensor.
3. Radar: the radar waves make use of the low energy, high frequency electromagnetic waves which are emitted by the sensor and are transmitted along the probe which is submerged into the into the medium to be measured. The impulses upon hitting the medium are reflected back towards the probe and then to the sensor. The sensor then calculate the liquid level by finding the time difference between the impulses sent and the impulses reflected. It is also referred to as Time Domain Reflectometry.
In context of the shipping business, leaks and cracks in the ships or in hatch covers are the most dangerous thing for any kind of commercial or non commercial shipping business. They are a great blow to the integrity and safety of the ship. They raise a question of protection and reliability of the ship and the shipping company. No matter the leak or crack is big or small; it can cause a severe catastrophe which will leave a bad mark and negative reputation of your company. The shipping industry from the very beginning is fighting with the dilemma of leaks and cracks in ships. It is constantly in battle with leaks and cracks.
It often happens that due to constant contact with water, the protective layers provided on the outside of the ships erodes away and cause leaks and cracks in the hatch covers of the ships. It is second to impossible to prevent the leaks or cracks, especially in the ship used for commercial purposes such as goods transportation, as they pass through rough usage on daily basis. Though prevention is not possible but the leaks and cracks can be detected and repaired by making use of different techniques and methods. Finding the leaks and cracks in the ships, is in itself an extremely difficult and strenuous task if done manually. But by making use of Hatch Cover Ultrasonic Tightness Testing device this procedure can become quite simple and easy. The whole process of detection is quite easy and can be easily done by a single individual with little training.
The ultrasonic tester device is used for the purpose which will enable you to find the leaks and cracks in the ship in the shortest possible time span. The tester device comes in the form of kit which comprises of a device, a generator, a receiver and headphones. It is battery operated. Some companies provide batteries while others do not, so you might have to purchase them. After placing the batteries in their place, just attach the receiver and the headphones to the device. After turning on the generator, place the device inside the cargo and close its hatch covers tightly.
Now you can check the Tightness of hatch with Ultrasound, through scanning the complete hatch cover and hearing the sound through the receiver and the headphones. There should be no sound, and where ever you hear the slightest beep or pulse just mark that area. It will be exactly the place where the leak or crack can be detected because from that place the ultrasonic sound waves would be leaking. Keep scanning the entire ship and the cargo and keep on marking the places where you detected the slightest sound. After detection you just need to call the repair man who will take care of rest of the things. All this procedure takes just few hours or if your ship is too big it may take one or two days. It is not only cost efficient but also saves your time and lots of energy.
The level of liquids in small quantities can be easily measured or evaluated through observation but when the measurement of liquids is required on large scale such as industries, it requires proper and precise measuring of the liquids or other media. The containers or vessels are gigantic and one cannot open them without taking proper safety measures and precautions. For this purpose, different types of liquid level indicators are used for measuring and monitoring of the liquid levels which is necessary for smooth and regular working of the industrial functions.
One of the most latest and advanced method of achieving accurate and standard levels is to make use of ultrasonic level indicator. It is one of the easiest ways of monitoring and managing the precise and standard liquid levels in different industries and plants. This method is highly recommended and used due to its high functionality and health friendly properties.
Different applications and usage
1. It is used for the measurement of caustic liquid chemicals in chemical industry that cannot be directly opened due to safety purposes and require precautions.
2. It is used for the detection of fluids in standing pipes especially in those pipes which are investigated and opened for maintenance.
3. It is used for measuring the level of fuels in automotive components for example in oil tankers carrying furnace oil or petrol, transmission assemblies etc.
4. It is considered perfect for measuring different layers of fluid on top of each other or second layer. For example, in the petroleum industry, the ultrasonic level indicator is used to measure the oil layer over the water layer.
5. It is also used in the fire extinguishing department and industry to measure the level of cooling agents in the cylinders and sprinklers systems.
6. Some factors which can affect the performance of the ultrasonic level indicators are;
7. The corroded or pitied container or vessel walls can cause distractions in the sound pulses which get back to the transmitter, altering measurements.
8. A sharp curvature of the container can also results in distorted sound pulses hence changing measurement figures.
9. The path of the sound waves emitted from ultrasonic device if obstructed by some obstructions such as pipe fills or baffles, can cause false measurements.
10. The liquid’s acoustic properties can also effect the ultrasonic measurements.
11. It is essential to maintain the constant temperature levels otherwise it may also alter the sound velocity of the liquid providing inaccurate readings.
12. Various other factors such as foam, bubbles, steam or turbulence on the surface of the liquid can also results in altering the accurate measurement of the liquid level through ultrasonic level indicators.
It is better to take into account all such factors and remove them before measuring the liquid level through ultrasonic device only then it will provide you with precise and accurate liquid level measurements. Otherwise it would lead towards inaccurate and faulty measurement which could result in some accident or problems.
It is an agreed upon fact that for measuring the level of the liquid inside the container, the best way is to just open up the lid and peek into the container. But at industrial scale, where there are tremendously huge containers with liquids inside them, this possibility does not work. The only way through which the level of the liquid inside these huge containers can be measured is with the help of different level measuring tools and instruments available in the market, now-a-days. Just by attaching these liquid level indicator to the outside of the container or immersing the body of the device in the container, the measuring level is displayed on their meter and the industrial staff comes to know about the level of liquid in the container.
If there is some highly volatile or chemical liquid is present in the container, its lid is completely sealed to avoid any kind of spills and to prevent fumes from escaping and polluting the atmosphere. The seal does not allow the staff to take a look inside the huge tanks containing liquids so they have to relay completely on the level measuring gadgets. In such situation, ultrasonic level indicator works best. It is a non contact liquid level measuring device which is very handy and can even take measurements from a distance. It can easily measure the liquid level through the walls of the tanks and also possess the capability to sense the existence of liquid, solids and gases.
Due to its variety of superb characteristics, the ultrasonic level indicator device is definitely a tool that is class apart from rest in the category and possesses complete reliability. Other kind of liquid level measuring tools can just measure after having a contact with the material. So these devices are totally useless and spending on them is wastage of money when it comes to measuring the level of solids, liquids and gases in the sealed containers. There is no match of ultrasonic level measuring devices when it comes to measuring the deepest wells inside the huge containers.
The ultrasonic measuring devices possess a unique characteristic of taking measurements even from a vast distance. This ensures complete safety and protection of human beings who are working at the industrial site. In case of measurement of dangerous and volatile chemicals, gases or liquids, the industrial staff remains perfectly safe from their life threatening effects. There might be some conditions in which the long range capacity of the ultrasonic signals to measure liquid level might be affected but that is just in few instances such as if the walls of the container or the tank are eroded or corroded, variations in the measurements can be observes, irregular shape of the containers can cause deflection of the ultrasonic waves in odd directions, turbulence, bubbles or foam on the surface of the liquid can also cause changes in the readings of the device.
So it is important to remove the possibilities of such conditions before using the ultrasonic measuring devices to avoid variations in measurements.
The overall cost of checking the tightness of hatch covers has greatly increased with the increase in the labor costs and increase in the price of the materials. The bigger the size of the ship, more expensive the checking process is. In addition to being expensive, all such procedures are quite time consuming and painstaking. This is the reason that many of the ships are sailed without conducting any type of checks on them.
The involvement of the latest and high tech technology into this field has resulted in the innovation of ultrasonic testing tools and devices which has improved the overall efficiency of the testing process in terms of cost, time and energy. It has enabled the owner to save lots of money, time and efforts which are required in case of manual checking. Buying a good Hatch Cover Ultrasonic Tightness Testing device is just an investment of one time which proves highly beneficial in the long run. The shipping company is required to buy the device just for once and this will save millions of dollars every time the conduction of test takes place. You can conduct limitless numbers of ultrasonic tests with a good ultrasonic device. It will pay off your investment in just few tests.
Despite the availability of this superb and amazing device and technique, many of the ship owners are still not aware of use of this device for checking the leakages or cracks in their ships. The amount of money which they can save from testing during a year can be spent on buying a new ship and expanding their business. They are still involved in conducting the same old traditional methods of conducting leakage testing instead of checking tightness of hatch with ultrasound. The traditional testing process which they adopt is long, tedious and extremely expensive. It wastes lots of time and energy besides money. The repairs even take longer time than finding the holes and cracks. But still it cannot be claimed with surety that ship is completely leak or crack proof.
The delay, results in missing the deadlines for the delivery of the shipments to the required place. This delay cost a penalty from the clients as well as from the marine authorities which are required to be paid from the pocket of the ship owner. By making use of ultrasonic testing devices the ship owners and managers can easily overcome all such problems with far less cost, spending less time and energy. Due to the rapid and precise detection of the leaks and cracks, the shipping companies can gain a well reputed name and can establish their worth in the market. So it is highly recommended for all the ship owners and people who are running shipping business, to adopt this latest technique and device for checking leaks and cracks in their ship and to save them from tremendous loses in the future.
The shipping and cargo industry has faced the major dilemma since it has been established, is the unanticipated and rampant leakages inside the cargo hatches. It still exists even after so many years. The water that finds the way through the leakages or through unseen cracks or holes, enters the cargo's, and results in the destruction of the valuables and things which are worth millions of dollars. The destruction of the goods in just one cargo is enough to render huge losses and set back the company into debt and in some cases even bankruptcy. This not only contributes towards decreased profits to the company but also cause significant injury to the credibility and reliability of the company among the clients and the insurance companies. The leakage and seepage is a major threat to the shipping companies.
For all these reasons, different companies have been trying to devise different methods and techniques to control these unexpected leakages, for past many years. Many different methods were devised for this purpose, but most of them were extremely expensive and required lots of time for surveying. The size of the ships is getting bigger and bigger with the passage of time, which means lots more expenses and much more time required to do complete analysis and investigations, before clearing the ship. All such lengthy, tiring and costly procedures required weeks and even month to complete which results in the ships missing their deadlines. The missing deadlines results in different penalties by the dock industries and also by the clients.
To handle and address, all such issues and other related issues, the shipping companies diverted towards making use of hatch cover ultrasonic tightness testing devices. They are meant to test and check any leakages, holes or cracks for the prevention of any type of leakage. This magical device enables the companies to cut down on both cost and time required to inspect the cargo. The only cost which is required is purchasing of the ultrasonic device. Once you have bought the device, you can easily conduct the checking of tightness of hatch with ultrasound, all by yourself. The time required to conduct the scan of the entire ship is just few hours, or it can be up to one or two days to the maximum depending on the size of the ship, if it’s extremely huge and severely damaged as well.
The checking of tightness of hatch with ultrasound devices and technique has gained extreme popularity among the shipping industry due to its convenience of use, cost reduction and time reduction. The companies, who have completely inculcated the use of the ultrasonic devices for checking tightness of hatch, are enjoying big time profits and credible reputation in the industry among the clients. They are able to establish themselves, as reliable and credible companies who are never late in delivering their shipments on time. This has enables them to escape the penalties from the authorities as well as from the clients.
For ensuring the smooth and flawless industrial operations and performance liquid level indicators are used. Due to their ability to monitor, they ensure the control over the level of liquids in gigantic containers, repositories, and pipelines in various industrial plants.
It is often not possible and safe to measure the liquid level in the giant containers or vessels or to take a view of the interior of the huge sized tanks or repositories; therefore liquid level indicators are used. There are two different methods to measure the liquid level indicators point level measurement and continuous level measurement. Either of this method is used for ensuring safety standards and maintenance of quality. There are multiple industrial applications of these liquid level indicator methods in different industries. Some of them include the following;
In food and beverage industry: for the maintenance of the company’s reputation and quality standards in the beverage industry, it is vital to maintain smooth and consistent taste of the products. To achieve this aim, different kinds of level sensors are used for milk, beer, wine or other ingredients tank gauging. Other kinds of food factories such as chocolate factories, biscuit factories, candy or sweet making factories and other similar kind of factories make use of ultrasonic level indicators for the maintenance of their standard quality.
In petrochemical plants: it has very important function in the petrochemical plants. The tank gauging of the highly volatile and caustic acids is necessary for ensuring highest safety and protection against any kind of explosions or to prevent any accidents. To achieve this aim, mostly non contact liquid indicators such as ultrasonic level indicators, are used. Because they can be easily operated and controlled from a distance ensuring safety.
In sub-marines: the sub marines extensively make use of liquid level indicators for the indication of extinguisher levels in the multi bank cylinder rows. Besides, ultrasonic level indicators are also used to check any type of leakages or cracks in the hatch covers of ships and cargo's. They ensure safety of not only the ship and goods but also the safety of the ship crew on board.
In fire extinguisher department: for carrying out the functions of the fire extinguisher department, liquid level indicators are vital gadgets. The cylinders used by the fire extinguisher department contain cooling agents which extinguish the fire. The function of the liquid level indicators is to maintain the standard quality of the cooling agents in the cylinders so that they properly work in case of any emergency situation.
For keeping check on water reservoirs: it is important to keep a constant and continuous check over the water reservoirs for their smart and intelligent usage for different functions. The detection of the water level in huge water reservoirs such as dams is done through liquid level indicators. They control the water level which is utilized for creating electricity or for supplying water to the rural areas or for any other purpose.
This simple technique and device has multitude of uses and functions in different types of industries. It provides a simple and trouble free control for smooth functioning of different industrial operations.
It has now become a common practice to make use of ultrasonic equipment as it is one of the reliable ways of testing the watertight integrity of hatch covers, doors, ventilators etc. ultrasonic testing is the only way through which you can evaluate the estimates of required or acceptable amount of compression.
