Seamor Marine Debuts New ROV with 3km Capacity

fiber optics tether with its Chinook ROV. Able to dive to 600 meters (2,000 feet), the Chinook ROV is equipped with a sensor skid carrying two Imagenex sonars: the 965A digital multi-beam imaging sonar and the DT360 multi-beam profiling sonar. These sonars are operated simultaneously using an Ethernet switch to the fiber optic tether multiplexer, allowing the EISA team to navigate and inspect tunnel walls in almost zero-visibility conditions. Auto depth and auto heading functions help them safely navigate the tunnel.One of SEAMOR’s partners in Finland consulted with the EISA team onsite

Unique Group Signs Exclusive Agreement with OTAQ Offshore

in the offshore environment, the DragonFish’s high precision laser measurement system generates sub-millimetric measurements of welds, chains and other targets from a low cost easy to operate package.  Unique Group will also represent OTAQ’s new Eagle IP range of high quality IP ethernet underwater HD cameras and IP integration infrastructure products. This equipment, along with a number of additional specialist systems, will be made available to clients through Unique Group offices located in the partnered regions.  OceanSENSE System (Photo: Unique Group

support. “We have selected SBG for the good performance/price ratio and the high level of service. The SBG technical support team is available, reactive, and committed,” adds the Shom professional. Another key factor when choosing the INS solution was the ease of use. Once connected through Ethernet, the Navsight inner web interface guides the user during the installation phase. For example, a 3D view of the boat shows the entered parameters so that the user can check the installation in real-time. The embedded filter also controls and validates lever arms and antenna alignment during this

The field-replaceable phased-array transducer design enhances position accuracy, eliminates the need for speed of sound correction and reduces the drag on an undersea vehicle. This instrument also provides ethernet connectivity, helpful in today’s ever more sophisticated undersea vehicles.SPRINT-NAV functions well, even at extreme angles (Photo Courtesy Sonardyne)Meanwhile at Sonardyne, the Syrinx DVL has been incorporated in an innovative solution - the hybrid acoustic-inertial navigator SPRINT-Nav

supplied many sensors and probes for Oceaneering's ROV ranges, hydrographic and oceanographic instrument designer Valeport worked closely with the company's engineering team to meet challenges in communication and connector requirements. The Valeport sensors in the Midas Bathypack were ethernet enabled to offer precision sound velocity, conductivity, temperature, depth and altimeter data, which is used to enhance the operational capability of the Freedom resident vehicle. The subsea vehicle is also equipped with Valeport’s compact and robust environmental monitoring sensor, the Hyperion
