TCR ATSCO in Kuwait wins a Stress Analysis project from KOC

TCR ATSCO based in Kuwait have won a project of stress analysis of a main header line.

The entire line was previously buried under ground but it has been now dug and exposed. KOC, the client was experiencing some leakage problems due to gasket leaks which they presumed was due to vibrations originating after exposing the line. KOC removed soil to about 3 meters below the line. The line was designed as per the underground operations and now since the line is exposed to up to 3 meters from the bottom, client is facing vibration problems and hence the gasket leaks. The line also has insufficient supports to hold the operating pressures.

KOC has asked TCR ATSCO in Kuwait to conduct stress analysis, identify stress and load areas and to recommend and propose support type and locations.

TCR ATSCO will be doing the piping stress analysis as UG or AG line with modelling of nodes on CEASAR II for stress analysis. Node is one piping element say, flange, pipe, valve etc.

For more details on Stress Analysis of Piping in Kuwait you can contact Mr. Amit Bafna at +965-65072765

NDT Services at Mecca in the “Expansion of Grand Mosque – Haram” Project by TCR Arabia

TCR Arabia, based in Dammam is currently working as a NDT services contractor at the Expansion of Grand Mosque – Haram site in Mecca, Saudi Arabia.TCR Technicians Mr. Ehsanulla and Mr. Danish Faisal are currently working on this project.

Please view some of the photographs taken on the site of Haram Expansion Project (Grand Mosque – Mecca) where TCR Arabia is carrying out NDT services.

Al-Masjid al-Ḥarām (المسجد الحرام (pronounced [ʔælˈmæsdʒɪd ælħɑˈrɑːm] "The Sacred Mosque"), is the largest mosque in the world. Located in the city of Mecca, it surrounds the Kaaba, the place which Muslims turn towards while offering daily prayers and is considered the holiest place on Earth by Muslims. The mosque is also known as the Grand Mosque.[1]

The current structure covers an area of 400,800 square metres (99.0 acres) including the outdoor and indoor praying spaces and can accommodate up to 4 million worshippers during the Hajj period, one of the largest annual gatherings of people in the world.



The most significant architectural and structural changes came, and continue to come, from the Saudi status of ‘Guardian of the Holy Places’ and the honorific title of Custodian of the Two Holy Mosques (the other being the Mosque of the Prophet in Medina) been afforded to King Abdul Aziz. Many of the previously mentioned features – particularly the support columns – were destroyed in spite of their historical value. In their place came artificial stone and marble, the ceiling was refurnished and the floor was replaced. The Al-Safa and Al-Marwah, an important part of both Hajj and Umrah, came to be included in the Mosque itself during this time via roofing and enclosement. Also during this first Saudi renovation four minarets were added.

The second Saudi renovations, this time under King Fahd, added a new wing and an outdoor prayer area to the Mosque. The new wing which is also for prayers is accessed through the King Fahd Gate. This extension is considered to have been from 1982-1988.

The third Saudi extension (1988-2005) saw the building of further minarets, the erecting of a King’s residence overlooking the Mosque and further prayer area in and around the mosque itself. These developments have taken place simaltenously with those in Arafat, Mina and Muzdalifah. This third extension has also resulted in 18 more gates been built, three domes corresponding in position to each gate and the installation of nearly 500 marble columns.

Modern but essentially non-architectural developments have been the addition of heated floors, air conditioning, escalators and a drainage system.

The death of King Fahd means that the Mosque is now undergoing a fourth extension which began in 2007 and is projected to last until 2020. King Abdullah bin Abdul-Aziz plans to increase the capacity of the mosque by 35% from its current maximum capacity of 800,000 with 1,120,000 outside the Mosque itself.

TCR Arabia participates in the 2009 ME&CCD TEM&E at Saudi Aramco

TCR Arabia made an active participation in the Technical Exchange Meeting & Exhibition conducted by Materials Engineering & Corrosion Controls Division of Saudi Aramco, which was held last week in Dhahran.  TCR Arabia was one of the only 14 companies invited by Saudi Aramco to participate in this exhibition and technical exchange meet.

Helium Leak Testing by TCR Arabia in Saudi Arabia

Leak Testing is a form of non-destructive testing used for detection and location of leaks and for the measurement of leakage in either pressurized or evacuated Vessel / Heat Exchanger.

Leak for various reasons is a undesirable feature in a component or systems. Still leaks do occur in practice. Hence ,it is essential that leaks are effectively detected and remedial measures to plug the leaks are taken well in advance.

There are various measures of leak testing. Leak Test methods such as Ultrasonic, Bubble, Air Soap Solution etc have sensitivity upto 10 ( - 3 ) std cc / sec range. Helium Leak Testing method has many advantages in terms of sensitivity and reliabilty.

When leak test is carried out, it is necessary to remember that leak rate measured plays a important role.Helium Leak Detector detects leak of the order of 10 ( - 6 ) std cc / sec or better, depending on test method used to detect the leak.

Helium is used as a tracer gas for the following reasons:

- Helium gas is very rare in atmosphere (around 5 ppm). Thus background is very low.

- This gas is non toxic and inert, so does not react with materials and presents no health hazard to operator.

- It has high diffusivity penetrating leaks.

Prior to start of leak test, Helium Mass Spectrometer Leak Detector is calibrated using Standard Calibrated Leak. Vessel or Heat Exchanger is filled with Helium  gas. After specified time, potential leak areas like welds, flanged joints,tube to tubeshet joints etc are sniffed with sniffer probe.This is semiquantitative leak test method .

In case of Heat Exchangers,Vessel / Shell is pressurised with Helium at specified pressure and tube to tubesheet weld joints are tested by moving Sniffer Probe around joints to be tested OR Tubes are pressurised with Helium at test  pressure and plug joints are leak tested by moving Sniffer Probe around plug Joints.
