Ship Tank Calibration

To ascertain gain or loss in sales, purchases to provide only reliable means of maintaining adequate control over the storage & distribution & stock keeping & in industrial production process control, as Oils, chemicals & its allied products are very costly items business & service render from it. Profit & Loss depends on accuracy of ship tank or barge storage tank calibration work.

By using laser scanning and an extremely accurate and fast scanner supported by a powerful software. It is ideal for every ship, but especially for floating storage vessels, delivery barges, chemical tankers, bunker tanks etc, where accuracy is of utmost importance

No matter the shape of the tank or the deadwood inside, you can have tables accurate at any level. List and trim corrections are calculated accurately without the approximations and restrictions of the old style trigonometric methods Field measurements can be done in hours; hence there is no need to have your vessel waiting days to be calibrated.

Our skill and understanding of every tank detail and the ability to incorporate them into final tables makes us stand out among the crowd. We use the most accurate, reliable and fastest laser measurement systems available. International Method followed: API MPMS

Tank Settlement & Survey

If we consider a Steel Storage Tank like a plastic bucket, when we pour water into the bucket the plastic walls tend to expand then again come back. After we have filled the bucket full, we notice that the top rim of the bucket tends to be slightly elliptical instead of circular in shape. When we stir our hand inside water we notice that the bucket walls tend to wrap. Same thing happens with the large storage steel tank of oil, chemical. As it is daily filled in and out with oil, chemical there tends to be deformation of the tank walls, pressure on the tank floor and specially if it is a floating roof tank, the roof due to uneven foam seal gap. Also due to enormous weight of liquid pressure exerted on the tank bottom, the tank bottom tends to subside which can cause cracks in joints and make the tank tiled on one side gradually affecting centre of gravity.

The tank can also tilt to one side due to uneven liquid head pressure. All this phenomenon is called out of roundness, tank tilt and tank floor settlement. If these are not studied and a detailed report made where you can repair, you can understand the catastrophe and safety/technical issues involved. It is this tank health that needs to be studied under API 653 B standard. To measure, study, analyze and make proper reports is very difficult. We have lots experience in the field of tank calibration since 1983, which make us expert to study the tank health with our accurate Total Station, Laser equipment and experienced engineers. After a few years of use, large tanks should always be studied for tank roundness, tilt and bottom settlement. We have mastered this technique of tank health checkup which can also include a detailed ultrasonic thickness report of tank floor and shell as floors can corrode over time, especially MS tanks. So when tanks are decommissioned for any repair or cleaning, they should be studied as mentioned above. Just do the call or mail us. We are available to do this study around the world

Radiographic Testing (RT)

Majority of the welding works on pipes require a Radiographic examination of the weld. RT is performed to inspect the quality of the weld and ensuring that the weld is free of bubbles or foreign material inclusions which will compromise the strength and integrity of the weld. The flaw can be observed on the film where the Radiographic image is recorded, similar to the medical X‟Ray image.
