Hamburg Port Authority (HPA) has taken delivery of the 3rd integrated dual head multibeam survey system from MacArtney.
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.
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.
