Data Acquisition
The validation of theory to the real time physics / behaviour of the problem needs “quality and authentic input data”. Geo Marine believed and recognized the significance of such need for delivering safe, optimal and reliable engineering solutions.
For effective operation of single point responsibility, the business model embraced“ the state of the art real time data acquisition infrastructure” capable to meet the challenges and needs of engineering projects on land and offshore.
The spectrum of capabilities range from engineering survey to capturing of ocean climate, sub surface modelling (geology, geotechnical, dynamic and seismic characterization), application of one dimensional wave data acquisition for “Non destructive testing of super and sub structures.
