I also stole this more recent summery of what's know from another board
"At around 7am local time, a fire broke out by the lifting-fans near the engine-room of the Norwegian Alta-class air-cushion catamaran minesweeper KNM Orkla. MAYDAY was immediately radioed, and civilian vessels were soon on the spot, immediately evacuating 26 of the 33 strong crew. The fire took only minutes to spread to the bridge. The CO and six others remained onboard to fight the fire. As the minesweeper took part of the Norwegian naval excercise Flotex 02, which involved the majority of the Norwegian navy, it was possible to dispatch a number of naval vessels to the area, including three MTBs keeping the area clear of civilian traffic and establishing a safe-zone, the MTB-force tender KNM Valkyrien, the frigate KNM Bergen, acting as command-ship for the rescue- and firefighting-operation, and in time the large coastguard-vessel KV Svalbard.
At around 8am it was believed that the fire was under control, but sometime around 10am, the fire flared up again, much more intensive than before, and it became necessary to evacuate the remaining seven crewmembers and continue firefighting from the other ships. The fire proved impossible to put out, as it had spread to the glass-fibre hull itself, and in time the fire spread to the entire ship. At around 3 pm the navy had given up hope of saving the ship, and the burning hulk was moved to a location with shallow water (rouhgly 25 metres/82 feet) - it is now believed that the vessel may well sink during the night, and it is considered desirable to be able to raise the wreck if that happens; the navy wishes both to examine the wreck for any faults native to the class, and to see if there is any reusable equipment.
The safe-zone around the hulk has been extended to one nautical mile, as the ship carries 1500 20mm rounds and 4000 12.7mm MG-rounds, which apparently are cooking off - numerous small explosions have been reported. The ships fueltanks, reportedly holding around 60 tons of Marine Diesel Oil, are also on fire, and the nvay has decided to let this burn - there are several fish-farms in the area, which will be hit hard if the fuel-oil leaks, so it is considered better to just let it burn out. The hulk was still reported as burning at midnight, Norwegian time."
