ABSTRACT Harbours and their access channels need to be dredged to the nautical depth to ensure safe vessel passage. When […]
SILAS software has been developed for users of acoustic systems who want high detail (ultra high resolution) from their acoustic measurements. Our users are hydrographic surveyors, geologists, port authorities, governmental organizations and scientific institutes. Dredging- , Hydrographic companies and Port Authorities use Silas to obtain more information about water depth, silt layers and sub bottom characteristics. Besides sediment quantity/layers, also the sediment type and sediment characteristics can be established, as well as information on possible obstacles in the bottom. Geologists use Silas in combination with profilers, boomers or sparkers, to obtain detailed information for sub bottom sediment classification.Read more
Stema RheoTune for setting of the nautical depth doing so by measuring the yield stress, viscosity and density of the fluid mud. This enables portmanagers to save costs on dredging.
