There are four important phases that we work through when undertaking hydrographic surveys. These videos show you the processes and work completed in each phase.
Operations Director, Dave Field provides an overview of the pre-mobilisation phase of a marine survey. This important detailed planning phase begins in Brisbane, Australia and turns the project proposal into tangible personnel, equipment and logistics. It includes bench testing, checking and configuration of equipment for trouble free use in the field.
The first part of the mobilisation phase involves installing and checking equipment and software on the vessel on site. The second part involves conducting bar checks to calibrate the sensors and ensure that all data captured during the survey will be accurate. The first two phases are crucial when it comes to the success of the third phase – the actual field work.
The longest phase of a marine survey is the Field Work phase – executing the survey. It comprises tide gauge infrastructure, patch tests and calibrations, and data collection. It involves working the area within weather constraints to get the best utilisation from teams and achieve the highest quality data in the most efficient manner.
The last phase, Post Processing is when the data collected in the field is converted into the final deliverable format for the client. After the data has been collected in the field, it can be processed on site or in the office, depending on the client’s needs and schedule. The data processing phase is when we sign off on the integrity of the data and conclude the project.
