what is ultrasonic testing?

ultrasonic testing is my speciality. it’s my job, my career. ultrasonic testing is a method where we use sound energy to inspect or check the flaw inside of the material. ultrasonic testing also is use to make measurement, to check the character of the material or the configuration of the material being inspect.

how’s ut work?

there are several functional units in ut. it consists of a pulser, probe or transducer and a crt screen. probe is an electronic device that can produce a high voltage electrical pulses. it converts mechanical energy (vibrations) to an electrical energy, thus produce a high frequency sound. the sound energy then propagates through the materials in the form of waves. if there is something inside the material, such as crack blocking the path of the sound, part of it will reflected back to the surface. the reflected wave then transformed into an electrical energy by the probes and is displayed in the crt screen.

how to measure?

in ut, measurement is a critical part. 5 years working in this field, i found that calibration is the heart of the ut inspection. it will reflect on how precise your measurement. even 1 milimeter deviation will make your measurement run from the actual location s of the flaw.

there are a lot of topics that can be discuss in ultrasonic testing, subscribe to blog my blog. i’ll send it straight to your email.

on august last year, i started working as a freelance ut inspector. i got paid on daily basis and i tell you what, it is more rewarding. i earned a very competitive price for my skills and competencies. my first job is to install petronas carigali new platform, puteri. puteri located at the border of malaysia-vietnam offshore. the distance from shore? mmmm, i’m not sure but it took about 26 hours travelling via crewchange boat. as far as i know, it located near bunga kertas fpso. here are some of the picture of my collection for this project.

this project started in the middle of august and finish one and a half month later, early october. the main contractors had several difficulties during the installation, the main problem is due to bad weather. but after a month and a half, there she is, puteri, standing right in her location.

the puteri topside was constructed by hl engineering at their own yard at lumut, perak. this is also my first jacket installation job, it was a new horizon for me as i had to perform the inspection or do the scanning while the pile was very hot using the hot-temperature couplant and probes.

after this project, i went for another two installation projects, sumandak ‘b’ at labuan offshore and ppp merlasakti jacket and topside installation at surabaya offshore, indonesia.. but sorry guys, i have no pictures or photos to show. i didn’t plan to start a blog but i promise to get a photo of every job i involve so i can share it with the world.
