Specific instrumented stations
nke Instrumentation has a range of data buoys that are versatile instrumentation stations ideally suited for collection and measurement of oceanographic, meteorological and water quality data parameters. Those specific instrumented platforms are completely adaptable to any applications’ needs. It is possible to integrate NKE Instrumentation’s monitoring instruments, such as the underwater monitoring instruments, within the specific instrumented platforms. The specificity of those buoys is that there is a complementary service of installation of training that can also be provided. The company can offer dedicated technical solutions for all environments and requirements.
Description - The profiling buoy measures the meteorological parameters of the air at a height of 2 m and records the physico-chemical parameters of the water column. The buoy is wet on a 60m isobath by two anchors or two dead bodies. A profiling float moves in the water column from the sea surface on a 60m depth on a cable which also functions as an inductive line of communication between the PLC and the profiling float. The profiling buoy is autonomous and supplies all sensors from batteries recharged by solar panels. All the data is synthesized by the buoy that transmits them to the ground. The buoy integrates the GPRS antenna in one location, as high as possible and ensuring optimal radio wave transmission.
Description - The freshwater instrumented station that was set up in Vierzon, in France, is a seaside or continental waters station. It can be set up in shore, pontoon or waterfront and it is designed for the measurement of water and air parameters. The aim of this structure is to add a multiparameter probe in order to detect hydrocarbons. It is also possible to add a weather station and a current sensor (ADCP sensor) and the data are then transmitted via 3G/4G, UHF or iridium transmission. NKE Instrumentation is responsible for the whole setting up from the metallic structure to the multiparameter probe which is place within a metallic pole.
Description - The WiSens automated receiving unit allows a wireless automated monitoring of the physico-chemical parameters of the water via fishing vessel based on WiSens logger technology from NKE Instrumentation. It is possible to use any WiSens from the WiSens data loggers family and the WiSens are provided in their dedicated protection that ensure general functioning of the WiSens as well a sufficient waterflow at sensor part to maintain qualitative measurement.

Description - The aim of the SIMEO buoy is to bring together in one equipment the sensors that will collect information on the life of marine vertebrates, whether flying or swimming. It can be installed in an offshore wind turbine area or in a Marine Protected Area. This autonomous buoy is able to count fish, cetaceans, but also birds and can record their trajectory and their behavior.
Description - This meteo-oceanic measurement buoy comes from a collaborative research & development project. The buoy allows to measure the wind with the greatest possible precision and in all the meteo-oceanic conditions that can be met on an offshore wind site. The buoy is designed and manufactured in France. BLIDAR is a collaborative project which aims to develop a weather-oceanographic buoy to accurately quantify the energy resource, especially and above all the wind potential measured with a LIDAR, available on offshore wind site. This project is conducted in partnership with the organizations EOLFI, IFREMER, IRSEEM and NKE Instrumentation.
Description - Piezometer V2 is designed for in situ measurement and monitoring of pore pressure for geotechnical and hydro-sedimentological applications down to 6000 meters. The pressure of the fluids between the solid grains of the sediment is one of the crucial controls for the stability of sediments. The piezometer instrumented stake is inserted into the sediment and provides the possibility to measure the pore pressure in different depth levels. The evolution of this dynamic parameter can be monitored in a short period of hours or some days as well as for several months.
