Hydrographic surveying

Accurate data for safe waters

Hydrographic surveying forms the basis for safe navigation, the sustainable use of waterways, and informed decision-making in coastal and offshore projects. Using state-of-the-art technologies such as multibeam echo sounders, GNSS positioning and high-precision sensor systems, seabeds are mapped and analysed in detail. This results in accurate maps and datasets that are indispensable in fields such as harbour construction, environmental monitoring, offshore energy and infrastructure planning.

At SITECH Deutschland, we have taken on the Europe-wide distribution of innovative solutions in hydrographic surveying. Our focus is on building a strong network of qualified dealers and partners across various countries. Together, we aim to make state-of-the-art surveying technology accessible, make projects more efficient and further improve the quality of hydrographic data throughout Europe.

Our manufacturer, Seafloor Systems Inc., is a globally established provider of hydrographic surveying solutions based in the USA. The company is renowned for precise, robust and user-friendly systems – ranging from echo sounders and complete surveying solutions to customisable platforms. With decades of experience and a clear commitment to innovation, Seafloor Systems supports customers worldwide in the successful implementation of challenging hydrographic surveying projects.

Unmanned survey vessels

Seafloor is a market leader in dynamic platforms that extend the capabilities of conventional survey equipment and enable surveyors to analyse hard-to-reach underwater environments. Seafloor’s turnkey USV platforms combine professional technology to carry out data collection missions at sea efficiently.

TriDrone Gen. 3

The TriDrone is a compact, unmanned survey vessel (USV) designed for precise hydrographic surveys. Thanks to its stable three-pontoon design, it is easy to transport and can be deployed even in hard-to-reach or hazardous waters. Equipped with integrated sonar for depth measurement and GPS support, the TriDrone delivers reliable data in real time. It is operated by remote control, is highly manoeuvrable and offers a long operating time of several hours.

HyDrone Gen. 4.5

The HyDrone is a lightweight, unmanned survey vessel (USV) designed for hydrographic surveys. Its sturdy catamaran design enables easy transport and reliable operation even in challenging waters. With the option to swap out modern sensor technology and optional autonomous navigation, it is a compact platform that grows with the task at hand. It delivers precise measurement data efficiently and safely – ideal for professional applications in rivers, lakes and coastal areas.

EchoBoat-160

The EchoBoat-160, a 1.60-metre boat from Seafloor Systems, is a compact, unmanned survey vessel (USV) designed for precise hydrographic surveys. Thanks to its modular design, it can be individually equipped with various surveying systems such as sonar and sensor systems. It operates remotely or autonomously, enabling efficient, safe and cost-effective hydrographic surveys with an operational duration of up to 8 hours.

EchoBoat-240

The EchoBoat-240, a 2.60-metre boat from Seafloor Systems, is a high-performance unmanned survey vessel (USV) designed for high-resolution hydrographic surveys, particularly in shallow or hard-to-access waters. Thanks to its modular design, the system can be individually equipped with various surveying solutions such as single-beam, multibeam or other sensor systems. With a high payload, autonomous or remote-controlled operation and an operational duration of up to 8 hours, it enables efficient, precise and flexible surveying operations.

HydroCat-550

The HydroCat-550, a 5.50-metre boat from Seafloor Systems Inc., is an unmanned survey vessel (USV) designed for precise hydrographic operations. Thanks to its stable, independently mounted pontoons in a catamaran design, it offers high precision and payload capacity as well as autonomous navigation. It is ideally suited for hydrographic surveys, inspections and environmental monitoring tailored to your needs – even in rough seas.

Hydrographic instruments

For a range of surveying and mapping tasks involving water bodies, we offer the tried-and-tested single-beam and multibeam sonars from Seafloor. Our equipment packages for hydrography and geodata collection can be tailored to the performance requirements of any project.

Single-beam Sonar

Single-beam echo sounders are characterised by reliable, point-specific depth data and high accuracy. They are suitable for simple surveying tasks and offer good value for money.

Multibeam sonar

Multibeam sonars achieve a high degree of precision and accuracy by time-stamping each sound pulse they transmit and precisely measuring the time and angle of the echo. Our equipment can be used to create detailed 3D terrain models of the seabed.

Sound Velocity Probe (SVP)

We offer state-of-the-art solutions for measuring the physical properties of water. The probes include a sound velocity probe (SVP) and a CTD (Conductivity, Temperature, & Depth) unit for measuring pressure, turbidity, temperature and depth.

AutoNav and AutoNAV Plus

The AutoNAV system is designed to simplify planning and navigation for autonomous hydrographic surveys – ideal for smaller projects. The AutoNAV Plus is the enhanced version, featuring an integrated industrial PC for recording survey data.

SmartCastTM

The SmartCast™ has been designed to automatically lower a sound velocity profiler to depths selected by the user. The winch can be mounted on the front of the USV and uses an IP69k encoder to track the SVP.

Collision Avoidance Assist

Detects obstacles in real time and provides reliable collision warnings – ensuring safe navigation even in challenging waters. Easy to integrate and intuitive to use. Greater safety, less risk.
