Ensuring the integrity of oil and gas pipelines and structures requires specialist monitoring with sophisticated hardware and software. This is an area where PMAC have invested heavily, offering the industry proprietary technology with enhanced data acquisition and management software to meet these demands.
PMAC Inspection, specialise in Cathodic Protection (CP) and Flooded Member Detection (FMD) surveys utilising our own proprietary equipment and multi-tasking engineers. With offices in Aberdeen and Singapore, PMAC offers worldwide services and have gained a reputation for delivering cost effective quality services.
Subsea Cathodic Protection Services
Regulatory authorities require constant evaluation/auditing of Cathodic Protection systems to ensure structural integrity. CP Surveys allow a system's ability to resist/avoid corrosion to be monitored, and any corrosion issues to be remedied before the onset of major failure. Based on the use of the Twin Cells (TC) probe technique, the PMAC system gives real time data measurement for both subsea pipelines and structures. Continuous CP and field gradient (FG) readings can be logged simultaneously, so PMAC are able to determine the anode current output and calculate the remaining life of installed anode systems. The PMAC Subsea Digitiser utilises the latest technology, adding increased reliability.
PMAC offer full service CP surveys with equipment and trained personnel as well as user operated equipment with training and support for data gathering and analysis.
With selectable multiple outputs of RS232 and RS485, 24Vdc or 110vac power supply and configurable baud rates, the system is flexible to allow the electronics bottle to be mounted on almost all ROVs, or even on deck (topside) if necessary. The PMAC Acquisition software, used in conjunction with PMACs processing software and CP experience, offers a choice of data reporting and interpretation methods to meet specific client requirements. PMAC also manage an extensive database of historical data which can be used to monitor CP trends to identify areas on interest throughout the design life of CP systems.
Our CP technicians hold CSWIP and/or NACE qualifications in Cathodic Protection to assure quality of service and may hold other qualifications such as FMD or CSWIP 3.4u enabling them to fulfil multiple roles on a vessel saving cost and bed space.
flooded member detection services
Flooded Member Detection by gamma source allows for offshore platform members to be inspected for flooding as a result of cracking, damage or weld defect without the need for high levels of cleaning required by other methodologies. As such a more tailored inspection plan can be prepared for more detailed investigation as well as other inspection tasks and techniques.
The PMAC ROV-mounted FMD system uses a range of small radioactive sources to cover member sizes from 150mm up to 3m diameter. The ROV mounting frame is variable to allow for members at any angle to be tested. Our proprietary software package analyses and records the data quickly and efficiently allowing for production of a report within hours of completing a work scope and single member results within minutes.
Our FMD technicians hold SEPA Radiation Protection Supervisor qualifications as well as other regulatory requirements for the region of operation to assure safety and may hold other qualifications such as CP or CSWIP 3.4u enabling them to fulfil multiple roles on a vessel saving cost and bed space.
