Ocean Nautical Innovations Develops Inflatable USP
The first inflatable Unmanned Survey Platform (USP) has been developed by Ocean Nautical Innovations of Belgium.
Named the Calypso, the vehicle comes standard with a single beam echo sounder, GPS, 3G/4G Wi-Fi communication, visualization and control tablet, and a waterproof case for sensors. It has an auto navigation module, which prevents the vehicle from hitting objects and allows for the planning of survey paths or areas. Because it is inflatable, one person can deploy the platform and it is easy to transport. 
The Calypso can be equipped with a range of sensors for hydrographic and environmental surveys and can be controlled by the cloud platform Atlantis. By using Atlantis, the data Calypso collects can be viewed in real-time anywhere in the world.  The software collects, processes, displays and stores the data which can be combined with survey data from other kinds of hydrographic equipment.

Furuno Expands NXT Radar Series
Furuno has expanded its NXT Radar series with the introduction of the DRS6A-NXT. 
A main feature of the new radar is the Doppler “Target Analyzer” that automatically changes the color of targets that approach a boat. Green echoes are stationary targets that move less than three knots. The echoes are red if approaching targets are traveling faster than three knots. The feature works independently of the boat’s own speed. 
The radar tracks and records up to 100 targets in every sweep. Using Furuno’s True Tail feature, the direction each target is moving is also shown. The “Bird Mode” adjusts echo enhancement, so birds can be easily located, and “Rain Mode” allows for target tracking in the rain. The DRS6A-NXT has both short and long-range target resolutions allowing for hazard location at 30 feet or out to 72 nautical miles. It has either a 2.3, 1.9 or 1.4-degree horizontal beam width on a 3.5, 4 or 6-foot open array. 
The NXT series radars have pulse compression and Doppler frequency shift sensing technology, and are designed for use with NavNet, TZtouch and TZtouch2 MFD’s. 

KROHNE Introduces Electromagnetic Flow Meter
KROHNE Inc. of Massachusetts announced the TIDALFLUX 2300 F electromagnetic flow meter is available.
The meter can be used for measuring effluent brine from dredging or mining activities, providing flow measurement in pipes between 10 and 100 percent full. The accuracy in partially filled pipes is less than one percent of full scale, while accuracy in full pipes is less than one percent of the measured value. The meter is wet-calibrated at the factory using direct volume comparison. 
Capacitive level sensors are integrated in the liner and electrodes are mounted at a height of ten percent from the pipe bottom to extend the longevity of the flow meter and provide more durability. 
The IFC 300’s application and device diagnostic and out-of-spec tests are available in the TIDALFLUX 2300F.

Dredge Yard will install small extended knives on the auger to loosen compacted river sands that are then transported by the auger to the suction mouth. The dredge will be built on two pontoons to allow for efficient floating capacity in shallow draft. 
Dredge Yard has offices in the Netherlands, The United Arab Emirates and the Republic of Turkey, where it designs, engineers, manufactures, inspects and tests a full range of dredging and mining equipment. 

Damen Dredge Uses SCHOTTEL Thrusters
SCHOTTEL provided two rudderpropellers type SRP 330 fixed pitch for the 60-meter (about 197-foot) dredge Tommy Norton, built by Damen Shipyards Group.
Schottel said the principal characteristics of the SRP derive from the combination of propulsion and azimuth steering, so there is no need for a rudder. The engine power is converted into thrust. The 360-degree rotation of the rudderpropellor provides full input power for manuervering.
Schottel said the SRP is the ideal propulsion solution where the focus is on optimizing the available power. The company provides advice and support in matters of hydrodynamics, tank and model tests, monitoring and steering options, FE calculations, ice-class considerations and special solutions.
