and unmanned ship is set to cross the Atlantic in April 2021, to commemorate the fourth centenary of the original Mayflower voyage and will rely on iXblue’s Octans Attitude & Heading Reference System (AHRS) to get key navigation information during its transatlantic voyage. Based on the Fiber-Optic Gyroscope (FOG) technology, the Octans AHRS will provide the MAS with highly accurate and robust navigation information such as the ship’s heading, roll, pitch and heave.“We’ve depended on iXblue Phins and Octans for years across many commercial and defense programs.

Fugro Starts Shallow Water Survey for 2Africa Fiber-Optic Cable Project

Offshore surveyor Fugro has kicked off its shallow water campaign for the “2Africa” subsea fiber-optic cable project.The cable project, once completed, will connect 23 countries in Africa, the Middle East, and Europe and deliver more than the total combined capacity of all subsea data cables serving Africa today.Fugro is providing offshore and onshore survey services, including a geophysical route survey and shallow geotechnical testing to overcome any challenges along the planned route.The Dutch company started its survey program for Alcatel Submarine Networks (ASN), which includes a

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:
