Tianjin Hydro-Tech Marine Technology Co. Ltd., a subsidiary of Beijing Hydro-Tech, was founded in February 2024. It is dedicated to three parts of business including monitoring product development, transducer design and parameter probe manufacture. Relying on the advantages of coastline location, we provide integration test and services for various unmanned platforms and training for operation of the full Hydro-Tech product line.   At present, Tianjin Hydro- Tech focus on the parameter measurement of temperature, salinity, depth, sound velocity, underwater noise and other environmental parameters, forming a series of products such as disposable products, self-contained/direct-reading products, towed products and component products. At the same time, we can also provide tailor-made service to fulfil the request of different application fields.   XCTD/XBT/XTD/XSV can be dropped without stopping the survey vessel while sailing. Then it can real-time measure the temperature, salinity and sound velocity profiling data of the seawater. It has the features of real-time, fast, hidden and low cost, which is very suitable for large-scale measurement and sensitive sea areas.   Expendable parameter measurement probe is composed of sensor head, firing gun and deck unit. The head is launched into the water via the firing gun. The sensor head would continuously measure the temperature, salinity, sound velocity and depth of the…

Mar. 12-14, Oceanology International 2024 was held at Excel, London. This is a scientific and technological conference where industry, academia and government share knowledge and connect with the world’s marine science and ocean technology communities.   Hydro- Tech Marine exhibited series products of multibeam echo sounder, towed and embedded side scan sonar, sound velocity sensor & profiler etc.   The most popular product in spotlight is our MS series multibeam echo sounder, which attracted many resellers and potential customers visit our booth. During the show, Hydro-Tech introduced the extraordinary performance, easy operation, Auto Survey function & super high cost-efficiency of the products in details.   MS400U has won the appreciation and praise of many customers. It built-in sound velocity sensor, lMU and GNSS module same as Applanix SurfMaster. The good sounding result, low noise data quality and compact with less cables is iwell recoganized, which fully demonstrate the market competitiveness of Hydro- Tech products!   Also, the side scan sonar attracted underwater  rescue and scientific research users. They seriously looked into the features of Hydro- Tech’ side scan sonar and showed interests to both of the towed sonar and embedded sonar.   As an exhibitor at the first appearance of OI…

Bridges are important parts of transportation, while the bridge piers located in water are the cornerstone of traffic safety. If underwater environment has large tidal range, rapid flow velocity, serious sedimentation and scouring etc., all of these are invisible safety risks. Built in 1973, MinjiangBridge is located in special geographical place where has big topographic drop from upstream and turbulent water flow, which has caused scouring hole for long time. This April, we undertake an important project of "Physical Examination" for Minjiang Bridge, which need high technology equipment to provide comprehensive data for security maintenance. Traditional bridge pier scouring survey, also known as underwater topographic survey, often uses RTK GNSS receiver to collect data manually. This method has 2 shortcomings. The operation is relatively dangerous, cause the flow rate near pile foundation is big and the water flow is disorder. Secondly, the operation efficiency is very low and the measuring accuracy may be difficult to meet the project requirements. Therefore, thiscase will use Unmanned Surface Vessel integrated with Hydro-tech MS400Umultibeam echo sounder. According to survey line designed base on survey area, MS400Uwill carry out moving measurement sounding underwater bridge pier to obtainhigh-precision underwater 3D data. This way efficiently solves the…

PrefaceAlong with the development of society, GIS data plays important role in economic operation. It was said that GIS data is the cornerstone of digital China. At present, GIS data on land is quite abundant, while underwater terrain data is much less. In some area, it is even blank. So the underwater bathymetry technology and application get more and more attention. Today, we will introduced a small size, high accuracy and low power consumpation multibeam echo sounder suitable for unmanned surface vehicle, which could survey the area that manned hygrographic ship can not reach, especially shallow water area.In the traditional knowledge of surveyors, underwater terrain surveying and mapping work is down on big hydrographic ship equipped with multibeam echo sounder cruising on large rivers or oceans. Therefore, only where is a ship or boat, there is a way to obtain underwater geographic information data. However, there are still a lot of unpopulated area in the country that are full of water area, but lack of ship.You may   ask what is the current status of the of unmanned surveying ship development? As the sharp tool of bathymetry, what is the development status of unmanned surveying ships configuration and equipment?At present, there…
