The Dutch Ministry of Infrastructure and Environment (Rijkswaterstaat Survey department IGA) has selected the Kongsberg Maritime EM 2040C very high resolution, shallow water multibeam system to spearhead its inland waterway survey operations.
For starters, the Ministry has in 2015 ordered five EM 2040C dual head and dual swath systems and the contract provides the option for additional systems up to a maximum of 11 within the next 10 years.
In addition, Kongsberg Maritime was awarded a 10 + 5 year maintenance and management contract to be serviced and coordinated form the Kongsberg Maritime Holland office.
The Dutch Ministry of Infrastructure and Environment is responsible for 2137 km of canals and rivers with 5472 km of waterways throughout the Netherlands, which must be surveyed on a regular basis in order to ensure safety of navigation.
For the bathymetry workload that is not outsourced, Rijkswaterstaat will use the EM 2040C systems as the primary tool to survey these waters on an ongoing basis. The first five systems were delivered at the end of 2015 with remaining units ordered to be delivered on demand when the vessels are available.
The EM 2040C ensures that highly accurate data is available in real-time. This makes it possible to conduct very cost-effective surveys with lower requirements for post-processing, due to the high quality of data available.
In addition to inland waterway surveys, applications include port and harbor surveys, post-dredging surveys, shipwreck exploration, habitat mapping, pipeline inspection and hydrographic surveys to a standard that exceeds IHO S44 Special Order and LINZ performance requirements.
