Situated on Curtis Island, Shell’s QCLNG Terminal stands as a cornerstone of Australia's liquefied natural gas (LNG) industry, serving as a pivotal hub for the processing, storage, and exportation of natural gas. Amidst its critical role in the energy sector, ensuring the integrity and reliability of its infrastructure is paramount. One essential aspect of this maintenance lies in the inspection and upkeep of the LNG jetty piles, vital structural components that support the terminal's operations. Leveraging AUS-ROV’s cutting-edge ROV technology has revolutionised this process, allowing for comprehensive and efficient inspections of these underwater assets. Through the use of remotely operated vehicles equipped with advanced sensors and tools, such as high-definition cameras, multibeam imaging sonars, high-pressure water blasting systems, ultrasonic thickness testing equipment, and cathodic potential measurement devices, the QCLNG Terminal can conduct thorough assessments of the steel piles with unparalleled precision and effectiveness. This integration of ROV technology not only enhances the safety and efficiency of maintenance operations but also ensures the continued operational excellence and safety of the QCLNG Terminal, reinforcing its pivotal role in Australia's energy landscape.
