Bathymetric Survey

Rovco’s bathymetric surveys, using either vessel or ROV deployed multibeam echosounders (MBES), are expertly conducted to produce reliable, repeatable results of the highest quality. Our client-centric approach ensures that we utlise the most appropriate sensor and survey packages to meet your requirements, providing data at the highest level of accuracy and value.

The Digital Terrain Models (DTM) we produce can be used in a variety of applications such as determining safe sailing depths, pre-, post- and real time monitoring of dredging and lay activities as well as determining the position of subsea features such as sand bars, shoals and channels.

Our highly trained and competent team have experience surveying across many industries and locations.

Geophysical Survey

A geophysical survey can be used to determine route planning, locate underwater obstructions or find cable & pipeline freespans and exposures. Side-scan sonars and sub-bottom profilers can be towed from a vessel or fitted to an ROV depending on the water depth, to provide the best resolution.

Geophysical surveys can be conducted alongside bathymetry surveys or conducted separately, depending on your requirements. High resolution geotiffs are created of large expanses of seafloor providing clients with a thorough understanding of potential obstructions, dropped objects or changes in seabed morphology.

Habitat Mapping

Part of a standard seabed acoustic assessment will involve the collection of habitat data. Using MBES and side-scan sonar, acoustic backscatter provides the information required to determine areas of differing seabed types, such as rock, sand and mud. This information can be used to inform a ground-truthing campaign. By using a variety of sediment samplers, and towed & drop camera systems, a habitat type can be formally identified.

Underwater habitat mapping is essential for planning and assessing any impacts that the subsea environment may experience such as storm surges, pollution and human activities.

Subsea Metrology

Our SubSLAM live 3D vision systems are the latest and fastest method for conducting point-to-point measurements for subsea metrology. This is the most advanced tool available, designed to supersede laser scanning in time of data capture and time of processing. The application of Rovco SubSLAM can bring about large reductions in vessel time and therefore cost.

Dimensional Control

The accuracy of a survey spread is reliant on precisely knowing the difference in separation and angular offsets of individual survey sensors. Dimensional control allows the offsets between the vessel and each survey sensor to be known to within millimeters, maximizing the performance of the survey spread. By using the latest Electron Distance Measurement (EDM) sensors and processing software we can repeatably determine dimensions such as distances, angles and roundness, amongst many others.

Oceanographic Survey

Oceanographic surveys can provide a complete understanding of the physical and chemical properties of a given area, vital for ensuring the efficiency of a project. We have experience with a range of sensors that allow characteristics such as tides, currents and waves to be measured in real time or deployed over long periods.

Reporting

We also recognise the importance of high-quality professional reporting and continue to be at the forefront of innovative data gathering, post-processing methods and modern electronic reporting techniques.
