Non Destructive Testing Non-destructive testing (NDT), are methodologies that can be applied both underwater and out of water. As their name suggests, these methods investigate the material without altering its integrity. Sometimes NDTs, especially in the case of complex structures, are complementary to each other, as different materials can coexist on the same element/structure or […]
Creation of Reference Networks Determination of geodetic reference points both on land and on offshore structures, created using both traditional and satellite technologies. Determination of networks in different coordinate systems. Topographic surveys with satellite systems GPS surveys with differential (DGPS) and kinematic (RTK) methods, for sub-metric and centimeter determinations in real time. Cartographic processing also […]
