OceanWise, Valeport Supply Monitoring System for HHA

trade from all over the world seeing 40% of the UK’s container traffic travel through its area.The bespoke system for HHA uses the latest technology to measure tide, weather and wave conditions at Harwich and Felixstowe. It includes a modern and dynamic environmental monitoring system with dual telemetry to ensure that continuous real-time data is available to the Port for its 24/7 operational needs.The integrated system provided by OceanWise was designed to incorporate best in class sensors within a robust, weather-proof Valeport Tidestation. Housed within these tidal observation hubs are Valeport

system from which surveyors can perform all of their LBL, acoustically-aided INS and Sparse LBL operations, with more functionality and capability than they’ve had before, including real-time SLAM calibration.This performance is achieved with Wideband 3, which allows, for the first time, sensor telemetry data (e.g. pressure, depth, temperature) to be embedded within navigation (ranging) telemetry data, which means that there are no pauses in tracking when installing subsea structures, allowing operators to know exactly what’s happening at all times and reducing risk

protocols used by Fusion 2 to command and control seabed arrays of its Compatt LBL transponders and vehicle-mounted ROVNav transceivers to Wideband 3.Wideband 3 allows, for the first time, sensor data (e.g. pressure, depth and temperature) from a Compatt to be to be embedded with navigation (ranging) telemetry data. This will have a big impact on operations such as structure installation, accelerating update rates by a factor of 10 and eliminating issues operators currently face with latency.To benefit from Wideband 3, Sonardyne has advanced its sixth-generation subsea hardware platform, with Compatt

– and high frequencies – necessary for improved resolution.”OBC vs. OBNThe fundamental difference between Ocean Bottom Cable (OBC) and Ocean Bottom Node (OBN) is that the traditional sources of technical downtime in OBC – terminations, connectors, power distribution and data telemetry – have been eliminated in designing the node to be a battery powered 4-channel flash memory autonomous seismic data recording unit. The removal of the need for power distribution and data telemetry allows for complete freedom in the spacing between receivers and the improvement in reliability

. Listed as a UNESCO World Heritage site due to its diverse nature, it is an area of strict environmental conservation.MacArtney has delivered six measuring stations to a German energy supplier in May this year including six Tide Masters designed by British manufacturer Valeport, equipped with Data Telemetry Units. The Tide Master device acts as a water level recorder; it can accurately record the height of the water and record meteorological data by utilizing an ultrasonic wind speed and direction sensor. Five of the units included pressure sensors to determine the changing water levels for the purposes

Soundnine XTP Sensors Deployed on Polar Buoy

modified drifting buoy. The XTP sensors are accurate to 0.005 deg. C; 10 to 20 times more accurate than temperature sensors on previous UpTempO buoys. The sensors are clamped to a jacketed wire rope tether. They communicate with the buoy through the wire rope using Soundnine’s inductively coupled telemetry.  The small size and streamlined shape of the XTP sensors should improve the survivability of the system through winter freeze-up (ice ridging) and allow this buoy to provide data throughout spring break up and the following summer

The demands of operating in harsh environments made these tools robust and inspired fully waterproof variants. Unfortunately at the time limitations in energy storage, autonomy and telemetry made seafloor crawling robots a novelty rather than a productive tool. This has changed.Through the surfToday C-2 Innovations, Inc., (C2I) has developed a family of capable, production ready, seafloor crawling robots to take users back through the surf zone and into the sea. This family includes
