MacArtney Supplies Time Saving Solution to MMT

NEXUS MK C is a fully customized plug-and-play multiplexer for work class ROVs and is a mobilization time saver. Fitted to new ROVs or as an upgrade to existing systems it can handle data for ROV setups that require multiple cameras, sonars, attitude sensors, manipulators, cable and pipe trackers. The NEXUS MK C is the latest delivery in a series of seven multiplexers provided to MMT since 2018.The NEXUS MK C system provides connectivity between the vessel and the ROV sensor package in one compact unit. The topside unit features an open interface that is versatile and perfect for data acquisition

Van Oord Wins Cable Install Work

Taiwan.Van Oord is responsible for the transportation, installation and burial of the 111 inter array cables, with a total length of approximately 135 kilometers, and the three export cables, with a total of approximately 145 kilometers. To carry out the work, Van Oord will deploy its cable-laying vessel Nexus, equipped with a cable carousel with a capacity of 5,000 metric tons. Van Oord’s own trencher Dig-It will bury the cables to the required depth. The installation work starts in 2021.The 900 MW Greater Changhua 1 & 2a offshore wind farms will be the first cable project in Taiwan for Van

Emerson Launches Roxar Tempest 8.2

Tempest ENABLE, Emerson’s uncertainty management and history matching module, center on greater connectivity to other IT ecosystems leading to the closer integration of geology and engineering, simpler workflow setup and improved risk and uncertainty analysis. To this end, the system now supports the Nexus* and CMG simulators, several cluster queueing systems, such as LSF, PBS and UGE, and it is easier to connect other third party and internal applications into the workflow. Post processing and analysis of the Big Loop ensembles is also now fully integrated.Tempest MORE 8.2, the reservoir simulator

version ideal for  use in extremely shallow water (<2 metres).  The operating console is the same in either case enabling the transceivers to be inter-changeable. In addition, the 1100 series of transponders now all feature data telemetry functions which can be utilised when used with the Nexus 2 USBL.  The transponders themselves can be used without telemetry with all Applied Acoustic USBL systems, as well as those from other manufacturers, thereby maintaining their overall flexibility. To meet the challenges faced by surveyors involved in shallow water, ultra-high definition geophysica

.   According to the manufacturer, key to the success of the system, and fundamental to its selection as part of this project, is its reliable, stable and repeatable positioning performance that is delivered by the advanced Sigma 2 bidirectional acoustic protocols. Additional attributes that make the Nexus 2 the preferred choice include its intuitive user interface, its simplicity of deployment and overall versatility, Applied Acoustics said

the ORCA 1 survey proved to be highly satisfactory;   “Our Nexus USBL was integrated with a GNSS aided inertial navigation system POS-MV WaveMaster, to provide accurate geo-referenced positioning of the seabed anomalies and proved to be a great addition to our system arrangement. We found the Nexus system very easy to use and it greatly increased our efficiency and overall operational effectiveness.   At the end of November 2016 we followed up our original work and  surveyed the planned well ORCA 2, close to ORCA 1 using our side scan sonar, magnetometer and our Nexus USBL for
