A fire alarm went off; the location of the fire was confirmed, and a team went for investigation. Heavy smoke was observed coming from a spare cabin. The incident occurred on a vessel working within 500m of a rig. The rig was informed, the vessel stopped work and immediately left the 500m safety zone. A fully equipped fire team entered the cabin and it was found that the smoke was coming from an expired line-throwing apparatus (LTA) cartridge, which was being kept for disposal.
The expired LTA box was removed from the location and kept on the main deck.
