Efendi is an electrical engineer from Batam, Indonesia who has more than 12 years of experience in the oil and gas industry.
As a senior ROV pilot, he has worked in this field for more than ten years and, over the past three years, he has progressed into the underwater inspection field.
In 2017 Efendi attended the CSWIP 3.4U course at TWI Malaysia and, after getting the CSWIP 3.4U certificate, his position was upgraded to inspection engineer. He is now at TWI Malaysia to attend the ACFM Crack Microgauge Operators course.
He works onboard IMR vessels (inspection, maintenance and repair) and the diving support vessel (DSV) and his job involves the inspection of jacket platforms as well as pipeline inspection.
As a 3.4U inspection engineer, Efendi assists clients on various topics. For example, onboard a vessel he is in charge of scheduling, giving comments about the directions the vessels should take or to which side of the platform they should move. His team give instructions to the ROV pilots or the divers to do the job of data collection. Once they get hold of the recordings and the data, then they use software to interpret and comment on their observations and distribute the report to their client. The client would be the final decision maker based on Efendi’s team analysis and reports.
Efendi mentions that there are numerous experienced CSWIP 3.4U certified inspectors in Indonesia, however, not many people are familiar with the ACFM technique. Despite Indonesian government agencies owning and operating ACFM equipment, many of the technicians are only internally trained rather than certified in the technique.
During one of his previous projects, Efendi faced the challenge of fixing the tubular member of a platform using magnetic particle inspection (MPI) as well as ultrasonic flooded member detector (FMD), which was when he realised that having the knowledge of ACFM could help him solve this problem. Now, being between jobs, he has had some time to invest in his career development, so he applied to attend the ACFM course, hoping that the certificate will assist him getting a position in an onshore project.
Alternating current field measurement (ACFM) is an NDT technique used for the detection and sizing of surface breaking cracks in metallic components and welds. The significant advantage of this electromagnetic inspection technique is that it combines the concept of eddy current testing (ECT) with the alternating current potential drop (ACPD) technique, which can result in more accurate detection of surface cracks.
The CSWIP ACFM course covers an overview of NDT techniques, electrical and electromagnetic theory, ACFM detection/identification of cracks, weld inspection by ACFM techniques, sizing for length and depth, reporting, and backing-up data.
Similar to all of TWI’s NDT courses, this training is in accordance with the requirements of ISO 9712 and ends with the certification examination.
