New Tool for Subsea Wireless Crack Monitoring
, easy to deploy wireless network solution which can be retrofitted to offshore structures and subsea assets. Seatooth ACFM units are user-configured to take readings as required, from once a minute to once per month. Seatooth ACFM can be configured as standalone sensors or within subsea wireless networks. As standalone devices, information is harvested by fly-by ROV or a diver. When configured as a wireless network on offshore platforms, real-time data is streamed wirelessly through the splash zone to an asset management control station located either on the platform or on shore
Using Subsea Technology to Drive Down Costs
, on May 18 and 19, 2016. These control and monitoring systems can increase subsea production and strengthen field economics for operators by improving asset integrity management and flow assurance. The presentation will focus on three main cost-saving solutions: Seatooth PipeLogger, Seatooth Wireless Networks and Seatooth Inclinometer. Seatooth PipeLogger The Seatooth PipeLogger can be used to measure the internal temperature, corrosion, flow, leaks and vibration of subsea pipelines without the need to physically penetrate the pipe wall. The system can be easily installed or retrofit,

transport of the data to the gateway via its wireless mesh system. Because the SFRSS mesh network operates at lower frequencies, it can communicate at ranges of up to 3 miles between nodes and is significantly less sensitive to foliage, obstructions, and moisture when compared to traditional wireless networks

the development of tactical edge network technology. His robust, efficient protocols for wireless, tactical networks are used across DoD. He has led and architected the development of next-generation, emulation-based network modeling that is key to the scientific understanding of mobile, wireless networks and critical in developing systems that have a high level of assurance in meeting mission requirements. Mr. Adamson's innovations have transitioned to a number of programs, reducing cost and directly supporting the DoD goal of deploying effective network-centric and autonomous tactical systems
Deep-sea Internet Being Developed at UB
, “The Internet Underwater: An IP-compatible Protocol Stack for Commercial Undersea Modems,” at the 8th annual International Conference on Underwater Networks & Systems. Hosted by the Association for Computing Machinery, the conference runs Nov. 11-13, 2013 in Taiwan. Land-based wireless networks rely on radio waves that transmit data via satellites and antennae. Unfortunately, radio waves work poorly underwater. This is why agencies like the Navy and National Oceanic and Atmospheric Administration use sound wave-based techniques to communicate underwater. For example, NOAA relies

to a masternode, is based on the theory of underwater optical networks (UON). By means of UONs, the optical signals transmitted by the Sensorbots are intelligently linked, using so called ‘multi-hop’ networking technologies, not unlike that used for cell phone and other land based wireless networks. This entails that information and data is ‘hopped’ between the nodes to overcome optical range limitations of underwater signal propagation. In essence, this means that one will be able to apply Sensorbots like strings of pearls over great distances - with full utilization of
