Effendi Adds ACFM to his CSWIP 3.4U

Effendi, an electrical engineer from Batam, Indonesia, has over 12 years of experience in the oil and gas industry. He spent the first 10 years as a senior ROV pilot before progressing to underwater inspection, where he has worked for the past three years.

It was in 2017 that Effendi gained his CSWIP 3.4U certificate, having taken his training at TWI Malaysia. This certification saw him upgraded to the position of inspection engineer and he has now returned to TWI Malaysia to attend the ACFM Crack Microgauge Operators course.

Working on the inspection of jacket platforms as well as in pipeline inspection, Effendi works aboard IMR vessels (inspection, maintenance and repair) and also on a diving support vessel (DSV).

As a 3.4U Inspection Engineer, he assists clients on various topics. For example, Effendi may find himself in charge of scheduling a vessel, where he will provide comments on the direction the vessel should take or which side of the platform they should move towards. His team give ROV pilots and the divers who collect the inspection data. Once gathered, this information is interpreted with software and comments are made on the team's observations before a report is made to the client. The client then makes any final decisions based on Effendi's team's analysis and reports.

While there are many experienced CSWIP 3.4U certified inspectors in Indonesia, Effendi explained that not many are familiar with the ACFM technique. Although Indonesian government agencies own and operate ACFM equipment, the technicians are usually only internally trained rather than certified for ACFM.

One of Effendi's past projects saw him face the challenge of using magnetic particle inspection (MPI) and an ultrasonic flooded member detector (FMD) to fix the tubular member of a platform. It was during this work that he realised that knowledge of ACFM would help him solve the problem, so he decided to take some time between jobs to invest in his own career by applying to attend an ACFM course. Effendi hoped that this certificate will help him get a position in an onshore project.

Alternating current field measurement (ACFM) is an electromagnetic inspection technique used for the detection and sizing of surface breaking cracks in metallic components and welds. The significant advantage of this particular NDT technique is that it combines the concept of eddy current testing (ECT) with the alternating current potential drop (ACPD) technique, which can result in a more accurate detection of surface cracks.

The CSWIP ACFM course includes an overview of NDT techniques, electrical and electromagnetic theory, ACFM detection and identification of cracks, weld inspection with ACFM techniques, sizing for length and depth, reporting, and backing-up of data.

Similar to all of TWI's NDT courses, the ACFM training is in accordance with the requirements of ISO 9712 and ends with a certification examination.
