Many naval shipwrecks are in deep water or in mud so nasty that even if in shallower depths, have visibility of about nil. Not so with the recently lost Helge Ingstad, which for now at least, is in the shallows of a crystal clear fjord in Norway at depths that enable small surface ROVs and scuba-equipped salvage work.
For those under a rock for the past month, HNoMS Helge Ingstad is a Fridtjof Nansen-class frigate of the Royal Norwegian Navy. On 8 November 2018, the frigate collided with the tanker Sola TS in Norwegian waters, was severely damaged in the collision and beached:
The cables didn’t hold and she slipped down the ledge where she rests today.
The Norwegian Navy this week released two videos from the wreck. One of them piloting the Blueye Pioneer underwater drone inside her hull, and another recovering Naval Strike Missile (NSM) launch canisters from her topside.
The NSM is a 13-foot-long, 900-pound anti-ship missile produced by Norway’s Kongsberg Defence & Aerospace and it is being shopped by Raytheon in the U.S. to replace Harpoon on frigates and LCS vessels. The range is 100+ nm and it is optimized for use in so-called green or blue water. Nansen-class frigates tote eight of these. More on the NSM here.
Of note, Blueye is also a Norwegian company. More on the ROV, which only runs like $6K, here.
