UK-based specialist pipe measurement technology company Optical Metrology Services (OMS) Ltd has successfully completed an on-site internal weld inspection survey for a major oil company. This is the first time that a combination of laser, video and ultrasonic inspection methods have been used in a production environment to inspect the profile of root welds on pipes. The survey was carried out by OMS’ US-based operation.In late 2009, OMS was approached by a main contractor on an oilfield project and asked to provide a team of on-site inspectors to carry out a full inspection survey of a number of subsea modular valve manifold systems.
Using its laser-based dimensional measurement tools and video-based inspection systems, OMS was responsible for assessing the internal root welds for any defects. The inspection requirements covered the full range of weld features including crown height,
