With demand for multibeam echosounders on the increase, Ashtead Technology has invested in six new Reson SeaBat 7125ROV2 high-resolution multibeam echosounders.

SeaBat multibeam sonars are designed to meet surveyors need for fast and reliable operation with ultra wide swathe coverage and outstanding submarine data collection, even in the most challenging waters, and can be mounted on a ROV or a vessel.

The new generation SeaBat 7125ROV2, now available to rent from Ashtead Technology, builds on the field experience from many users around the world and brings unparalleled resolution and installation flexibility. Special emphasis has been put on maximizing operational efficiency and features such as variable swath width and roll stabilisation combined with a high ping rate and excellent data quality.

The SeaBat 7125ROV2 is the latest evolution of the SeaBat 7125 Series, and is specifically aimed at the oil, gas and renewable market. The 7125 ROV2 systems are supplied with Reson’s new FP2.0 software as well as the FlexMode option. The new FP2.0 software offers variable swath width from 45 to 165 degrees, with electronic beam steering (head tilt). The FlexMode beam forms equidistant beams across the full cross profile to a user defined grid distance. The remaining beams are formed as equiangular beams in a user defined high resolution sector. This high resolution sector provides the user with a very detailed profile of the pipeline with a very clean data set, which is fast to process, thus saving time and money.
