Conducting around 900 surveys per year in the port of Hamburg, Hamburg Port Authority (HPA) requires high-end products for their multi-sensor systems and survey vessels.

The vessel ‘Deepenschriewer IV’ is the smallest survey vessel of HPA and intended to carry out multibeam surveys for depth control and documenting in shallow water areas. For this purpose, MBT, MacArtney Germany, has effected supply, installation, and setting-to-work of a dual head multibeam echo sounder system suitable for hydrographic survey applications.

This solution comprises the following products: high-resolution multibeam echo sounder Teledyne RESON SeaBat® T20-R, a Valeport SWiFT sound velocity profiler, and a Valeport UltraSV.

Scope of supply

The dual head Teledyne RESON SeaBat® T20-R multibeam echo sounder configuration provides uncompro-mising survey data in a highly compact package designed for small vessel use. It is an all-in-one, fully flexible and fully integrated survey system allowing for fast mobilisation, minimal interfacing and low space require-ments. It is fully frequency agile from 190 to 420 kHz which ensures improved swath performance and reduced survey time.

Representing a seamless workflow, the Valeport SWiFT sound velocity profiler features rechargeable battery and LED status indicators for easy and fast downloading, reviewing, and translation of data into common SVP formats wirelessly. The Valeport UltraSV offers an advanced and exchangeable sound velocity sensor and is ultra-fast, ultra-compact, and ultra-dependable. The scope also consists of RTK GNSS and inertial sensor as well as a QINSy hydrographic data acquisition, navigation, and processing software package.

Ultimate flexibility

The units are intended for coastal, harbour, and inland hydrographic survey use. Featuring superior acoustic quality and high accuracy, this dual head survey system enables easy and quick downloading and sharing of data relevant in relation to hydrographic surveying.

Quality testing to meet the most demanding standards ensures optimum performance, thus allowing for good swaths in very shallow water as well as comprehensive surveys in big areas in a short time, specially in shallow areas, and thorough testing during dredging operations.
