Kraken, ThayerMahan Demonstrate SeaScout for US Navy
for target detection and real-time full resolution SAS processing to enable in-stride automatic target detection and classification.TENTACLE, an intelligent all-electric winch that hosts sophisticated algorithms for dynamic manual, semi-autonomous or fully autonomous control. The integrated motion reference unit tracks the motion of the host vessel, and the onboard software models and predicts the sea state. The winch can be deployed stand-alone or integrated into a completely Autonomous Launch & Recovery System (ALARS) for both manned and unmanned surface vessels. The complete system fits inside
New ASV Delivered for Post-hurricane Surveying
and history delivering ASVs for high-precision bathymetric surveys, water quality analysis, hydrographic surveys, shallow water, force multiplier and many other applications. The ASV was delivered with a fully integrated Edgetech 6205 multi-beam echo sounder (MBES), R2Sonic 2022 with Type II I2NS motion reference unit and dual antenna GPS system, as well as a surface sound velocity probe and a cast winch deploying a CTD—all tightly integrated with HYPACK software
Meet Kraken’s Tentacle Autonomous LARS
namesake in nature, the Tentacle Intelligent Winch may look unassuming from the outside, but its true capabilities lie within. The fully integrated electronic control module hosts sophisticated algorithms for dynamic manual, semi-autonomous or fully autonomous control of the winch. The integrated motion reference unit tracks the motion of the host vessel, and the sophisticated onboard software models and predicts the sea state. This allows the winch to predict timing of wave peaks and troughs and optimize the variable torque on the motor to minimize input disturbances through the tow cable.The operator
Canadian Hydrographic Service Grows Its USV Fleet
of USV usage. A profile of high-productivity, cost-reducing activities is being developed for both traditional survey tasks and survey tasks in previously denied, and currently unsurveyed, areas.The new USVs were delivered with a fully integrated R2Sonic multi-beam echo sounder (MBES), associated motion reference unit and dual antenna RTK GPS system, as well as a surface sound velocity probe and a cast winch deploying a CTD—all tightly integrated with HYPACK software.“The USVs will be used extensively to improve bathymetric, hydrographic and nautical data throughout Canada for waterways, estuaries
SBG Systems Launches Navsight Marine Solution at OI2018
software named Qinertia. By processing inertial and GNSS raw data forward and backward, Qinertia greatly increases accuracy especially during GNSS outages; it also fixes set up mistakes, etc. Available as MRU, with embedded GNSS, or using yours Highly versatile, Navsight comes as a Motion Reference Unit (MRU), providing roll, pitch, and heave or as a full Navigation Solution with embedded tri-frequency GNSS receiver, or using an external one. Fusing inertial data with satellite position in real-time, Navsight INS offers a continuous position in all conditions, such as surveying under a bridge
Trelleborg Suite Supplied to Prelude FLNG
“all in one” unit with built in roll and pitch sensors. The CAT III unit is quick and easy to set up, as it only contains two GPS antennas and the PPU switches on automatically the moment the antennas are pulled apart. Position and motion data of the FLNG is measured by the Motion Reference Unit (MRU) and the DGPS / GLONASS RTK based base station on the FLNG. The base and up to five PPUs are linked via a dedicated UHF frequency. The offshore operation requires a precision approach, monitoring and mooring software for the offshore oil and gas industry. Through the SafePilot
SeaRobotics Delivers USVs for Hydrographic Surveying
system leverages SeaRobotics’ expertise and history delivering USVs for high-precision bathymetric surveys, water quality analysis, hydrographic surveys and any other applications, the company said. The USV was delivered with a fully integrated R2Sonic multi-beam echo sounder, integrated motion reference unit and dual antenna RTK GPS, surface sound velocity probe and a cast winch with deployable CTD—all tightly integrated with HYPACK software. “The 2.5-m USV is one of the smallest systems capable of practical, general purpose MBES deployment,” said Don Darling, president
New Split Hoist System from Bosch Rexroth
the load and passively compensates for some of the ship’s movement. The passive in-line system is hoisted and held by an existing winch or crane. An actively controlled winch, typically mounted on the ship’s deck, then compensates for the remaining movement of the load. A motion reference unit measures movement of the vessel, and the system reacts to control the load’s position relative to the seabed. In this way, the system requires only 20 percent of power compared to conventional AHC systems. The new system was developed and designed fully in-house by Bosch Rexroth
New Fisheries Research Vessel for Angola
by a KONGSBERG K-Sync, 16-channel system to prevent interference between systems during multiple use of the various Subsea systems. Positioning for the Subsea package is provided by the KONGSBERG Seapath 330+ GNSS Dual Frequency Receiver (GPS/GLONASS) including a state-of-the-art MRU-5+ motion reference unit. The KONGSBERG HiPAP 502 Acoustic Positioning System completes this versatile Subsea package. “The delivery for Angola’s FRV is practically a standard fit for these types of vessels,” said Øystein Aasbø, Area Sales Manager – Subsea/Underwater
