Fitness-for-service assessment is a multi-disciplinary engineering approach that is used to determine if equipment is fit to continue operation for some desired future period. The equipment may contain flaws, have sustained damage, or have aged so that it cannot be evaluated by use of the original construction codes. API 579-1/ASME FFS-1 is a comprehensive consensus industry recommended practice that can be used to analyze, evaluate, and monitor equipment for continued operation.


Internal Rotational Inspection System (IRIS) is an ultrasonic immersion pulse echo technique that can be employed for the inspection of heat exchangers and condenser tubes. IRIS is capable of detecting corrosion, pitting and wall loss on both ferrous and non-ferrous materials on a wide range of tube diameters and wall thicknesses. The inspection allows for improved preventative maintenance programs by identifying damaged tubes.The ultrasonic principles which IRIS is based on can accurately aid in calculating the remaining life of the material so maintenance activities can be scheduled for future outages and also reduce the number of unplanned, unforeseen outages.


An Offshore container is portable unit for repeated use in the transport of goods or equipment, handled in open seas to and from fixed or floating installations and ships. We provide a range of services from construction to certification including: design review (drawings and calculations), load testing, vertical impact test, inspection and testing and quality control/quality assurance. We also provide consultation and/or modification of existing containers requiring certification.


This technique utilizes the Array Remote Field Testing technology, where a handheld bracelet scanner is used on the external surface of vessels, piping and reformer tubes / headers. It allows you to detect internal corrosion thinning, pits and cracks that can cause life-threatening leaks, pollution and property damage. The Bracelet probe offers a practical solution for the fast, economical inspection of bare, coated or wrapped pipes and gives rapid results in near real-time. In the case of reformer tubes some metallurgical anomalies such as permeability changes (which can lead to creep damage) can be detected.


We can gurantee extended on stream time of boilers by checking on the condition and integrity of boiler tubes using RFT. This inspection technique is adapted from the remote field technology (RFT) which is a low frequency AC (electromagnetic technique) conducted from the tube externals. In this technique, a signal is sent from the array exciter coils to the array detector coils. The time of flight of this signal is directly related to the wall thickness of the tube near both the exciters and detectors. One will be able to detect the defects such as general wall loss, localized wall loss (i.e. thermal fatigue, hydrogen damage, graphitization, flame side erosion, oxygen quality, caustic gouging and localized wall loss.


Low Frequency Electromagnetic Testing (LFET) is a used to detect material loss, pitting, holes, etc. due to corrosion using an electromagnetic field which generates eddy currents in the conductive material. LFET can be used on rough surfaces or surfaces with wet film coating as the scanner head does not require surface contact. This technique of inspection is widely used on storage tanks, tank bottoms and shells, pipelines and heat exchangers. Electromagnetic Acoustic Transducer (EMAT) is an ultrasonic non-destructive testing method which does not require contact or couplant due to sound that is directly generated within the material that is adjacent to the transducer. EMAT inspection can be used to detect flows, material property characterization and thickness measurements. This technique can be used on pipelines, boilers and pressure vessels.


Lifting operations can often put workers at great risk of injury if done incorrectly. It is therefore necessary for proper planning and supervision during lifting jobs to avoid injury to persons and/or equipment. This can be achieved when planning is done by a competent person who has the adequate training, knowledge, skills and expertise suitable for the level of task.


Have quarantined operations with guaranteed measurements, avoid leaks, guard against earthquake loads, and detect in-service leaks on floors by using inspection and calibration techniques via ultrasonics, acoustic emission testing, magnetic flux leakage tests and calibration tests.


Have trouble free operations and avoid costly shutdowns by preventative maintenance techniques via helium leak testing, acoustic testing, ultrasonics and QA/QC works on installations and repairs.


Magnetic flux leakage testing is a magnetic method of non- destructive testing that is used to detect corrosion, wall loss and pitting on tank floors in the oil and gas industry. Corrosion of tank floors (due to soil and tank contents) can lead to the loss of product and damage to the environment therefore it is necessary for this form of inspection to be performed to prevent occurrence of such problems. MFL testing can quickly pinpoint areas of wall loss on tank floors.


The coating process requires inspection at every stage to ensure compliance to the specification. From the preparation of the surface to be coated, through climatic condition monitoring to the dry film thickness evaluation, visual assessment and gauge-based testing ensures adequate process control.


Crane inspections are done to ensure the safe and proper working and condition of the equipment. These inspections are conducted in accordance with all applicable regulations, standards and engineering practices and involve thorough visual inspection, magnetic particle testing, liquid penetrant testing and load testing. Inspections are done annually or otherwise specified prior to each use, and during use to ensure safe operations.


Helium leak detection is used for accurately and safely locating and quantifying small system leaks into or out of a system. Helium is used as a tracer because it penetrates small leaks rapidly. It is non-toxic and chemically inert. There are two (2) types of leak detection methods:- 1) Vacuum testing- when helium is introduced externally with the detector located inside the part. 2) Pressure testing- when helium is introduced internally with the detector located outside the part. Helium Leak Detection inspection is mainly used to detect leaks in storage tanks, heat exchangers, vacuum vessels, piping etc.

WELDING INSPECTION (AWS Certified Welding Inspector)

Our AWS certified welding inspectors have over 20 years of experience in AWS D1.1 Structural Welding -Steel and API 1104-Welding of pipelines and related facilities which are used in many industries globally. Inspections are conducted from fabrication/construction to repairs to ensure that the weld is in accordance to codes and standards from the stage of documentation, execution and completion of final weld.


Rigging/Lifting Accessories inspection are conducted to ensure that the specific equipment is fit for use and is free of any defects and/or damages that may compromise normal operations. Inspections on items such as shackles, master links, slings, chain blocks, and lever hoists are carried out in accordance to its relevant standard for rigging and lifting accessories or manufacturer’s specification. Inspection on these equipment are done visually, and also with the aid of non-destructive testing such as liquid penetrant and magnetic particle testing.


Quality Assurance/ Quality Control (QA/QC) involves the inspection, documenting and monitoring of every aspect of a project. Our QA/QC inspectors ensure equipment and parts are operating as per applicable codes as well as meeting industry and regulatory standards. Control of Temporary Equipment (CTE) is a QA/QC procedure from Shell which is used to control the quality of temporary or portable equipment that is hired/supplied for a specific job. It ensures that the suppliers equipment is in compliance with onshore and offshore regulations and the procedure is done mainly to minimize or eliminate non conformance/faulty equipment which can create a hazard on the job site.


Rope Access is a safe method of working at heights where ropes and associated equipment are used to gain access to and from the workplace, and to be supported at this position. Rope access inspection has its advantages where the methods used mainly lies in the safety and speed with which workers can get to or from difficult locations and then carry out their work, often with minimal impact on other operations and the nearby area. Our personnel are individually certified with IRATA Level 1.
