Halliburton, TechnipFMC Launch Acoustic Sensing Solution for Subsea Wells

while improving reservoir knowledge, the companies said in a joint statement on Thursday."The Odassea service integrates hardware and digital systems to strengthen digital capabilities in subsea reservoir monitoring and production optimization," the statement reads.Halliburton provides the fiber optic sensing technology, completions, and analysis for reservoir diagnostics, while TechnipFMC provides the optical connectivity from the topside to the completions. Through the collaboration, operators can accelerate full field subsea fiber optic sensing, design, and execution, Halliburton and

detect surface and underwater threats and coordinate a non-lethal mitigation against them. The threats were divers (real and mechanical/dummy) and unmanned underwater vehicles (UUVs), including Remus and Riptide UUVs. Atlas Electronik’s Cerberus was used to detect the threats, while their SeaFox fiber optic guided mine countermeasure tool was used to intercept and inspect them and a Stingray capture net from Marine Arresting Technologies from Florida was also deployed. Approximately twenty people from companies and Navy groups took part. A CONOPS (concept of operations) plan was decided and setup

Subsea Umbilicals Demand Hit by COVID-19

the global economy recovers from the Covid-19 pandemic,” says Rystad Energy oilfield service analyst Henrik Fiskadal.Not the same downturnThe materials most commonly found in the manufacturing of umbilicals are high-grade stainless steel, carbon steel armor wire, hydraulic hoses, power cables, fiber optic cables and thermoplastic resins. In addition to the materials, engineering labor is the next largest cost input involved in the manufacturing of umbilicals. Therefore, the more complicated and unique is the design, the more strenuous and costly the fabrication and installation processes, Rystad

Exploring Under The ice (& Keeping your AUV in one piece)

addition to the most recent Antarctica mission, ISE’s AUVs have been to the Arctic multiple times. Notably, two of ISE’s AUVs created for Canada’s Project Cornerstone completed 1000km of under ice survey in 2010, and for Project Spinnaker ISE-built Theseus laid 100s of kilometers of fiber optic cable.A multitude of factors led to these successful operations, and in this article we’ll discuss some of the inherent dangers of working under polar ice and how they were mitigated.Why are under AUV missions challenging?Every time an AUV descends to explore unknown regions, there is aPhoto:

#Oi2020 History

In 1976, testing began by the Naval Electronics Laboratory Center of two fiber optic undersea tow cables. This was done to measure “changes in optical attenuation caused by cabling, tension, temperature and pressure,” according to the book Advances in Marine Technology, as published by the Marine Technology Society. The testing led to the six-fiber cable (as manufactured by ITT Electro-Products Division, as the caveat to commence the accuracy of using fiber optics in undersea tow cables.   Marine Technology Reporter has been commissioned to publish the Official “Oceanolo

are available via an accessible software user interface.  MacArtney Underwater Technology has been supplying multiplexers to key underwater technology industries for decades. The first MacArtney NEXUS multiplexer, produced in 1999, digitized analogue signals from the depths to the surface via fiber optic cables. In the present day, the NEXUS MK C is MacArtney’s most versatile multiplexer solution, built to meet the customer’s needs
