Locating pipes and cables is crucial for many marine and waterways projects. To this end G-tec uses various methods and equipments both magnetic and acoustic. The methods will be selected / combined depending on the type and size of the objects and whether they are located on the seabed or under it. Magnetometry surveys, for instance, allow the detection of small buried cables, which no acoustic method can do, by measuring the variation they bring about in the earth magnetic field.
After interpretation of the data, G-tec's geophysicists are able to provide both the object location and an estimation of its size (or mass, for magnetic surveys) in the form of interpreted maps, side scan sonar mosaics, etc. Besides pipeline/cable localization, G-tec provides different services before, during and after laying of pipelines and cables; such as route investigation, geological risks assessment, trenching assessment, etc. |
