LinkQuest Receives New Orders

Image: LinkQuest LinkQuest Inc. has been busy recently producing around 500 underwater acoustic modems for offshore oil field applications. LinkQuest's industry-leading underwater acoustic modems have been extensively used in the offshore oil fields worldwide. Over the years, rich experience has been garnered with regard to the application details, noise and multipath conditions, and acoustic instrument interference avoidance. LinkQuest produces a large number of acoustic modem models, designed for optimal performance under various application scenarios. Based on LinkQuest's extensive experience in offshore oilfield applications and competence in theoretical analysis, LinkQuest has closely worked with its customers to select specific acoustic modem models most suitable for the application, aiming to optimize system performance and increase overall system reliability. Recently, a large number of long-range deepwater acoustic modems were selected for seabed seismic monitoring applications. These modems will be used to interface with seismic sensors to monitor and explore offshore oil and gas field reservoirs in large-scale deployments. Dozens of UWM2000 and UWM4000 modems were selected for communication between surface ship/platform and downhole oilfield tools in offshore oil field projects. Several dozens of UWM2000H omni-directional and directional acoustic modems were also selected for monitoring critical sensor information from FPSO. With overwhelmingly superior field performance, large quantity production consistency and cost effectiveness, LinkQuest continues its dominance in the underwater acoustic modem market.

LinkQuest has recently received an order for 44 PMGS (Precision Marine Geodetic System) transponders and a PMGS surface station from the Japan Coast Guard. This special investment in the PMGS systems is based on the impressive measurement results obtained by Japanese scientists after the Magnitude 9.0 earthquake that occurred on March 11, 2011. Up to 24 meters of horizontal seafloor movement was detected. These new transponders will form several new arrays at Japan's ocean floors, further expanding the coverage of the areas of interest. They will be periodically monitored by research vessels in years to come. The complete Precision Marine Geodetic Systems (PMGS) are capable of detecting the movement of the ocean floor with 0.5 centimeter of accuracy for ranges up to 7,000 meters. These newly ordered PMGS transponders, combined with more than 100 systems already deployed in the field, will continue to play a key role in monitoring undersea earthquakes and Tsunamis caused by movement of sea plates on Japan's ocean floors.
