Use of AUV in Shallow Water, Return of Experience and Expectations

Using AUV since 2014 for shallow water survey mainly in West Africa in some of the most difficult area; zero visibility up to 4.5Kts surface current, ... We perform all the type of survey required by O&G offshore construction (pre-lay, as-laid, as-build). Taking advantage of acquired experience , we are now having some expectation for the near future.
We will also show the use of BV5000 as used…

Current and Future Applications of Acoustic Scanning in Marine Engineering Surveys and Inspections

The study highlights the advantages of using acoustic scanning in the survey of key walls, piles, defensive and other civil marine engineering structures, addresses existing and potential problems with this method and suggests a direction for future improvement. It is based on the summary of 25-year experience of marine engineering surveys by GT Corporation SE (Estonia) and its partners, with 10-y…

River Sediment Transport Monitoring by Means of H-ADCP

Monitoring stations in rivers and water courses are an important mean to obtain critical data about the different variables that play a role in the hydrodynamics and ecological processes. This is especially true during rough weather conditions when direct observations are not possible and even dangerous. A technique to determine the suspended sediment transport by means of fixed ADCPs at the side…

USV (Unmanned Surface Vehicle) RSV Sea Observer deploying the Seabotix ROV vLBV300 to increase safety.

For some years now, autonomous vehicles achieve more and more hydrographic survey operations. Their fields of action are becoming more extended and they allow reducing the costs of this type of intervention in comparison with conventional survey means.
If typical marine survey can be now well achieved thanks to USV, from inshore and coastal areas to open oceans and offshore bathymetry, the autono…
