IVM Hydro 300

IVM Hydro 300 - 3D Photogrammetry

The ultimate underwater inspection solution.

The IVM Hydro 300 is a versatile, compact, lightweight, and efficient solution for inspection and 3D reconstruction of structures and seascapes with the benefits of project time and cost savings over traditional methodologies. Combined with the IVM SLAM technology, the IVM Hydro 300 delivers real-time imaging during survey/inspection operations.

By harnessing modern point-cloud and mesh technologies; post-processing provides a detailed and manoeuvrable 3D visualisation and true scaled results; with submillimetric accuracy. The generated 3D models are retrospectively measurable, allowing for detailed off-site visualisation,
inspection, and comparison. This allows distribution with internal and external stakeholders for increased operational and management collaboration and decision making.

The IVM Hydro 300 is calibrated on location providing supreme accuracy based on local environmental parameters. The system works independently of navigational aids, so is perfect for shallow work as well as operations in water depths up to 300m. Utilising dual wide-angle cameras complete with goldsmith quality domes, the high-frequency frame rates and 75,000 lumen onboard quad strobes allow the system to work in the harshest of environments, including water with high levels of turbidity, irrespective of which, the system generates outstanding accuracy and exceptional results.

The IVM Hydro 300 is a multi-sector inspection tool which is deployable on Observation and Work Class Remote Operated Vehicle’s (ROV’s) and can equally be operated by divers making it a versatile and cost-effective solution for multiple subsea inspections.

The ability to deliver this service using both ROV’s and Divers offers flexibility regarding Client needs. Hughes Subsea combined with other OEG Group specialists can provide these services from our in-house Daughter craft and group CTVs which greatly decreases mobilisation time, carbon footprint, and cost. This allows Hughes Subsea to deliver prompt results, all of which are bespoke to the individual Client needs. It also provides Hughes Subsea the ability to be reactive to Client needs in the event of unscheduled or unexpected inspection requirements.

Hughes Subsea offers turnkey solutions for Client inspection and survey scopes encompassing all elements of project planning, procedures, operations, and reporting, thus providing peace of mind, ensuring the same standards are met throughout the project lifecycle, whilst enabling the project to be delivered in the most efficient manner and allowing the Client focus to remain on wider strategic goals and project/field developments.
