Health & Safety
Listening to its clients and assessing the lack of technology in this area, OMS has designed and produced a new version of WeldChecker, which has the same design concept as a London ‘bendy bus’ with a modular, flexible design. Te advance in hardware has imrpoved the product’s capability, allowing previously inaccessible welds to be measured for compliance – thereby guaranteeing they meet the client’s specification.
Advanced capability Taking this technology to the next level, OMS has developed more compact tools that are able to fit inside ever-smaller pipe diameters. Te capability is now at just 4in internal diameter, which means OMS can inspect welds using both laser measurement and visual data at approximately 100mm diameter and around bends in pipes. WeldChecker has been successfully deployed in a number of oil and gas projects around the world such as BP’s Devenick, Skarv and Galapagos projects, as well as Shell projects Gumusut, Llano and Cardamom. Where will internal weld scanning go
from here? OMS is currently looking at the application of this technology to a number of different situations. One application is to mount the tool to the line-up clamps for use in the critical welding path both onshore and offshore during pipeline welding. Another application is the inspection of tie-in welds on welded spooled stalks of pipe – this means while these pipes are spooled onto the vessel, the system would be driven by crawler perhaps 1km to perform the scan. Finally, it could be used on older pipes and structures to measure the extent of corrosion or pitting, or even to measure the extent of features in the pipe wall. Te system has also received significant
interest from the oil and gas industry, as well as the aerospace and nuclear sectors. Large operators are now asking for tighter tolerances to maximise production life, and also to make the pipelines safer through better welds. OMS provides a proven solution for both operators and welders. l
OMS has developed compact tools that are able to fit inside ever-smaller pipe diameters. The capability is now at just 4-in internal diameter, which OMS says makes it the only company that can inspect welds using both laser measurement and visual data at approximately 100mm diameter, and around bends in pipes.
WeldChecker has been successfully deployed in a number of well-known oil and gas projects around the world, such as BP’s Devenick, Skarv and Galapagos projects, as well as Shell projects Gumusut, Llano and Cardamom.
