Unique System FZE, a division of Unique Maritime Group (UMG), recently supported a significant hydrographic project that included the installation of Kongsberg’s EM 2040 multibeam echo sounder units for Bayanat for Mapping & Surveying Services (Bayanat) in two different vessels at Abu Dhabi, UAE.
The project involved the installation and commissioning of the full systems on board two identical vessels having approximately 12m by 3.5m dimensions with powerful engines suitable for manoeuvring and keeping straight survey lines. The stability of the multibeam system and frequency choices (200kHz to 400kHz) makes the unit perfect for working in this region. The pitch, roll and yaw stabilisation options available with Kongsberg multibeam systems makes the data more reliable and acceptable. The physical and angular dimensions of the vessel and equipment were measured by a highly experienced land survey team using their sophisticated equipment while the system was dry docked, and reports were generated.
Commissioning of the vessels was carried out at Esnad Port in Abu Dhabi jointly by Unique and Kongsberg in the presence of the engineering and survey team of Bayanat. The Harbor Acceptance Tests (HATs) and Sea Acceptance Tests (SATs) were carried out at the site, and results were tabulated and verified by the team along with the data processing team at Bayanat.
