The “Disruption” in AUV Trends

; AUV. It was the moment Ludvigsen says he realized AUV use in research had turned a corner.Remote missionsThe AMOS team, however, wasn’t the first to launch an AUV beneath the arctic ice. In 1982, Canadian researchers sent the AUV Thesueus made by Canadian company ISE under the ice to lay the communications cable of a Cold War acoustic array on the seabed from a research station on an island to one on an ice-flow. Recently, another ISE AUV made headlines in Australia for taking University of Tasmania researchers on a mission to survey the southern polar ice.Payload-flexible: ISE Explorer 6000 class

, A-size, very small UUV featuring a reconfigurable payload capacity that enables it to perform multiple maritime missions such as decoy, gateway buoy, neutralizer, data gathering, intelligence, surveillance, and reconnaissance. The latest generation SEAScout, is offering enhanced endurance, communications, and navigational accuracy, as well as new payloads.  This work builds on the successful integration of an acoustic payload demonstrated at ANTX 2018. This new compact UUV is designed to be readily and easily employed by US Navy sailors without specialized training, simplifying employment

This includes the power supply on which subsea installations such as Christmas trees, manifolds, sensors and other equipment depend to function. If the umbilical cable providing power and communications between the seabed installations and the surface fails, these pieces of equipment are useless.    “We saw that wells were shut down due to electrical failures and we recognized there was a need for equipment that could be put in place rapidly to generate electricity in remote
