Core offering

Ocean High Technology Institute (OHTI) develops and sells a proprietary suite of marine survey data processing software — including multibeam echo sounder processing, sidescan sonar imaging, underwater acoustic visualization, and 3D bathymetric mapping tools — along with related hardware such as shipboard electronic balances and oil spill detection systems, primarily serving government agencies, research institutions, and hydrographic surveying companies in Japan.

Product overview

Ocean High Technology Institute (OHTI) offers a comprehensive marine survey software portfolio centered on the OHTI-SoundPro integrated platform. The core software suite includes MarineDiscovery (multibeam data processing), LampyridEye (side-scan sonar processing), SoundingDiver (underwater acoustic imaging), MitoOshie (survey support with real-time display), Visual3DX (3D visualization), and OHTI Visual Web (WebGIS data management). Supporting modules include SeaProfile (sub-bottom profiler), OH-CPS (chart preparation), OH-SDIS/YS SUPPORT (data integration), and MitoIruka (underwater navigation). The company also develops hardware products including Pirka (shipboard electronic balance) and Vibro Recorder, and distributes Slick Sleuth oil spill monitors. The software portfolio supports i-Construction compliance and integrates QCtools for quality analysis.

Broad incumbents

• Furuno Electric Co., Ltd. Furuno is Japan's leading marine electronics manufacturer (WASSP multibeam sonars) and a co-marketing partner of OHTI's MitoOshie, overlapping in survey workflows but not in pure processing software.
• Teledyne Marine / Teledyne Technologies: Teledyne Marine is a portfolio of hydrographic, sonar, and instrument brands (including CARIS). The parent level acts as a broad incumbent competing across the same survey hardware/software ecosystem that OHTI addresses.
• Kongsberg Maritime (Hydrographic & Geosciences): Kongsberg produces integrated multibeam sonars and the SIS / Seafloor Information Systems software for hydrographic survey—a broader incumbent whose echo sounder hardware integrates with OHTI's processing software via standard formats.

Direct peers

• Teledyne CARIS: Teledyne CARIS provides CARIS HIPS and SIPS for multibeam processing and chart production, the most established direct competitor to OHTI's MarineDiscovery, particularly for hydrographic office and nautical chart workflows.
• QPS (Quality Positioning Services): QPS offers QINSy, Qimera, and Fledermaus for hydrographic acquisition, processing, and 3D visualization—directly overlapping with MitoOshie (real-time survey support) and Visual3DX (3D visualization).
• HYPACK (XCite): HYPACK is a hydrographic survey software suite for multibeam, sidescan, and sub-bottom data processing—the closest functional analog to MarineDiscovery and the broader OHTI-SoundPro stack, serving survey companies worldwide.
• Chesapeake Technology (d.b.a. SonarWiz): SonarWiz is sidescan and sub-bottom sonar processing software—the direct analog to OHTI's LampyridEye and SeaProfile in the international survey market.
• BeamworX BV: BeamworX produces NaviSuite-compatible tools and the Inferno bathymetric processing engine for multibeam data—closely comparable to OHTI's MarineDiscovery CUBE-based processing and SeaProfile sub-bottom workflows.
• EIVA (now part of Saab): EIVA develops NaviSuite and NaviModel for hydrographic data acquisition, processing, and 3D visualization—directly comparable to MitoOshie and Visual3DX functionality for survey and offshore construction markets.

Emerging players

• SonarMite / Echoview Software: Echoview provides advanced acoustic data analysis for water column and fisheries hydroacoustics—an adjacent specialization to OHTI's SoundingDiver for multibeam water column imaging.
