Geological surveys of seafloor
Marine construction projects include unique geological challenges and risks. Geological information and proper planning are vital for the projects’ success and in keeping costs under control.
Geological surveying is a central component in site selection processes and the characterisation of the project, and in minimising risks at each phase.
GTK provides reliable and unbiased information produced with the most suitable methods on the geological structure, sedimentation, erosion, and environment of the seafloor. Our marine geology unit is an independent expert team with a significant national role in increasing competence in the field, as well as maintaining this.
In addition to infrastructure construction, the information is needed in assessing the environmental impact and the state of the marine environment. Thorough surveying also makes construction projects more likely to be viewed as socially acceptable.
