On August 12 2000, K-141, a Russian Navy Oscar-II class nuclear-powered cruise missile submarine, known to the world as Kursk, was lost with all hands when it sank in the Barents Sea. Kursk, was a Project 949A (known by its NATO reporting name as Oscar II). It was named after the Russian city Kursk, where the largest tank battle in military history, the Battle of Kursk, took place in 1943 during WWII. One of the first vessels completed after the end of the Soviet Union, it was commissioned into the Russian Navy's Northern Fleet. At 154 m (505.03 ft) long and four stories high, she was the largest attack submarine ever built. The Kursk sortied on an exercise to fire dummy torpedoes at the Kirov-class battle cruiser, Pyotr Velikiy, flag ship of the Northern Fleet.

Among the many challenges facing E&P in the Brazilian deepwater pre-salt plays, is that of anchoring the flowlines, platforms, FPSOs and even buoys to the seabed which can be over 2000 meters deep. Petrobras has developed a simple and efficient method of doing this through the Torpedo Pile.In the case of the deepwater pre-salt plays in Brazil, specially at the Santos Basin, the distance from land to some of the proven plays like Tupi and Iara, which are around 300km from shore and pose complex logistics problems even on surface structures. Challenges, such as how to anchor a deepwater rig or FPSO to the seabed 2,200 meters down must be resolved. It is a long distance for anchors to travel, normally four or more anchors are used and these anchors need to be aligned.
