| Pressures of economics are driving the ROV industry to develop NDT equipment which will allow the ROV to detect, and assess, the presence of fatigue induced surface breaking defects in nodal welds and their associated heat affected zones. Two main techniques of NDT are currently being developed by Comex to provide ROV services to meet client needs. One is an MPI system and the other an Eddy Current system. Both are derivatives of equipment currently being used successfully by divers in the North Sea. The two systems are complementary to each other rather than in competition and offer a high degree of defect evaluation. This paper will discuss the requirements placed on the tool deployment system by the task, the worksite, the ROV characteristics and the... |
