"Technogenic Craters" Found at Damaged Nord Stream Pipeline Site

The Swiss-based operator of Russia-led Nord Stream 1 gas pipeline said on Wednesday it had completed initial data gathering at the location of the pipeline damage on line 1 in the Swedish exclusive economic zone and found "technogenic craters". "According to preliminary results of the damage site inspection, technogenic craters with a depth of 3 to 5 meters were found on the seabed at a distance of about 248 meters from each other," it said. Nord Stream 1 and Nord Stream 2, laid on the bed of the Baltic Sea from Russia to Germany, were damaged in September and the infrastru


Kraken Gets $1.1M Synthetic Aperture Sonar Order for NATO Navy Clients

Kraken Robotics  has secured a $1.1 million purchase order from an unnamed customer for several of its AquaPix synthetic aperture sonars SAS). "These systems will be integrated to Autonomous Underwater Vehicles (AUVs) for delivery to two distinct NATO navies. Delivery is expected in the first half of 2023." Kraken Robotics said .Kraken’s AquaPix is an off the shelf, configurable SAS that replaces high end sidescan systems at an, Kraken says, affordable price, while delivering higher resolution, range, and area coverage rates (ACR). Kraken says that the increased range

50-meter Section Missing from Damaged Nord Stream Pipeline

Damage to the Nord Stream gas pipeline from Russia to Europe was caused by powerful explosions, Danish police said on Tuesday, echoing earlier findings into leaks that erupted in the network under the Baltic Sea and that have been blamed on sabotage.In what a Swedish newspaper described as the first publicly released footage of damage to the system, film from a private drone appeared to show a gaping rupture in one pipe. Expressen reported a 50-meter section missing from one area of pipeline.Dwindling flows of gas from Russia, which once supplied 40% of Europe's needs, has left the

Today, more than 400 undersea data cables carry about 98% of international internet data and telephone traffic around the world. With so many nations depending on the thousands of kilometers of subsea pipelines, power, and communications cables that traverse the ocean floor, there is a real and present danger of sabotage to subsea infrastructure.The threat of subsea explosive ordinance is an asymmetrical threat where low-cost mines and explosives can damage and destroy critical assets, be they
