IVM Tech


Underwater Photogrammetry 

IVM's underwater photogrammetry camera "HYDRO series" is an underwater photogrammetry device that applies SLAM technology.

The HYDRO series continuously takes still images of the object, generates a 3D point cloud from the underwater still images, and creates a 3D rendering model. It is possible to create high-definition models of natural structures such as coral reefs, wave-dissipating blocks installed on the seabed, damage to harbor seawalls, and corrosion and expansion of underwater steel structures. Point cloud output can be done in real time using the IVM SLAM function, but by post-processing with dedicated software, it is possible to reproduce modeling with an unevenness of less than 1 mm. We have achieved 1/9,000 scale accuracy in underwater surveying and received Bureau Veritas certification in 2019.



The highly versatile HYDRO 300 features two cameras with large 1"/12 megapixel high-resolution image sensors, a GPU-based image processing engine, and a dedicated 75,000 lumen output (equivalent to 92 60W incandescent light bulbs). The underwater camera with integrated high-intensity LED can be attached to small ROVs such as BlueROV2, observation class ROVs such as Valor, and large work class ROVs, and can be used to monitor marine structures even in turbid underwater environments. We have accumulated a lot of actual measurements of infrastructure facilities such as objects, ports and dams.

``HYDRO 100'' has been reduced in size and cost to a size that can be mounted on small observation class ROVs such as BlueROV2. It is powered by battery power and can be operated using Ethernet cable communication, making underwater photogrammetry more accessible.

We not only sell the HYDRO series, but also propose combinations of the HYDRO series and ROV to meet your needs. We also provide underwater photogrammetry services upon request.


The HYDRO series includes the HYDRO 1000, which has an integrated structure that can withstand pressures of 1000m, and the HYDRO 3000, which has a special pressure vessel that can withstand 3000m pressure and has separate camera and processor parts.Each model can be attached to an existing ROV. It can be installed.

 Acoustic Corer (AC), Sub-Bottom Imager (SBI)

In construction phase of offshore project, minimizing the risk to cause delay is critical for the overall project cost. General derisking approach is to perform 2D high-resolution seismic survey, CPT/SPT, and physical ground sampling to evaluate the geotechnical properties and identify any geohazard, but the resolution and coverage still does not cover the entire footprint of the construction area. Kraken Robotics's acoustic sub-seabed interrogation technology can fill the gap exists in these technologies and thus minimize the existing risk.

Acoustic Corer (AC) is an advanced acoustic beamforming techniques to produce an accurate 3D acoustic volume below the seabed, approximately 14m wide, and 40-60m deep, to mitigate risk at foundation locations for offshore installations such as wind turbines or oil/gas platforms. AC provide 3D map of stratigraphic layers, and detect geohazards such as boulders >0.2m diameter and gaseous soil layers.

The data can be utilized also to correlate existing geotechnical data and extrapolate properties across foundation footprints.

Sub-Bottom Imager (SBI) uses advanced acoustics to provide a real-time view of the sub-seabed in full 3D in a continuous longitudinal path 5m wide by 5-8m depth of subsea penetration. The SBI integrates with industry standard survey software to delineate discrete objects, stratigraphy and geohazards with decimeter resolution. The SBI can be operated from a surface vessel for shallow water, or from WROV for deep water.


SBI can be utilized to identify boulders and other submerged items along pipeline/cable route, and for As-Laid/As-Built survey, integrity survey to map and measure burial of cable, The survey of the cable can be performed without interrupting power transmission.


Ocius Bluebottle

Class : Bathy , Beth

Hybrid power generation using wind, wave and solar power makes long-term marine research possible

The Bluebottle™ USV (Bluebottle Unmanned Surface Vehicle) is an innovative autonomous solution that has a large payload capacity that can supply sufficient power, and enables wide-range navigation and continuous ocean surveys for several months. It is an excellent system that brings innovation to the cost and operation aspects of conventional manned surveys in various ocean survey applications.

The main class are Bathy and Beth, both of which can autonomously survey a designated area for a long period of time using wind, wave and solar power. They can also observe in Sea State 5, and can store their sails in storms or strong headwinds to enable continuous observation and operation.

The latest design of the Bathy class is equipped with a 5kW diesel generator, which is rare for a sailing USV, and can supply a maximum of 4kW/average 850W (30 days continuous) of power to the payload observation equipment. This abundant power allows it to be equipped with not only a multi-beam echo sounder, which is essential for coastal bathymetry, but also a geological exploration sonar, which is necessary for pre-surveying offshore wind farm sites. It can also be equipped with a scientific fish finder and weather observation sensors, which together enable long-term observation at sea for one to several months or more.



Multi drone system USV

An unmanned surface vehicle that can navigate autonomously for up to eight days

The SeaCAT USV (SeaCat Unmanned Surface Vehicle) is a catamaran-type unmanned surface vehicle equipped with an excellent autonomous navigation and collision avoidance system, capable of early detection of collision risks on or near the water surface, automatic avoidance, and course change and return to normal.

It can be transported overland using a 4-ton truck or a 20-ft container, and is a groundbreaking marine survey platform that is not only equipped with many marine survey sensors (MBES, SSS, SBP, ADCP, etc.), but also has the ability to launch and retrieve small underwater drones and take off and land aerial drones.


The vessel will enable observations at Sea State 4 and will be powered by a small diesel generator for up to eight days. It can flexibly accommodate a range of operations, from multi-purpose surveys conducted independently to simultaneous cooperative operation with a general manned research vessel, and will contribute to seabed topography and geological surveys, oceanographic and meteorological observations, and O&M inspections in areas surrounding offshore wind farm facilities.

Subsea Tech is participating in Sea Clear, an EU Horizon 2020 supported project, to use autonomous robotics to map, identify and remove marine litter.
