Bathymetric survey is an essential factor in marine construction and dredging projects to assist in the understanding of the project requirements. It provides data on what specific and unexpected steps might need to be taken and allows for accurate deadlines to be set for the project.
Pre dredge surveys assist in the planning phase of the project whist progress surveys are vital information for the efficiency of the works. Our experience includes working with Trailer Suction Hopper Dredges and Back-Hoe Dredges, as well as Ploughs. We provide all key personnel with timely and easy to interpret data by integrating GPS positioning on the vessels and real-time data uploads.
We also assist coastal engineers providing survey data for beaches, rivers, lakes, dams and estuaries. Using this data we can generate volumes, cross sections, 3D TIN models, contours, charts and reports in many formats.
We utilise a range of vessels to navigate these waterways taking into consideration difficult access or sea conditions to achieve the results.
The main purpose of port and harbour surveys is to provide vessels with the information they need for safe navigation. The data provides ships with accurate depth measurements for the safe navigation according to the draft of the vessel. As the depths of channels and berths can change over time, regular survey is required. These surveys also detect hazards like large objects that have been dumped or fallen into the water, these need to be detected and removed as they pose a threat to vessel safety.
The information is provided to the Harbour Master of the port and promulgated in the hydrographic charts.
