The invention encompasses fire-escape models of off-shore rigs with emphasis on a ‘Detachable Island Rig’ (DIR), the latter instantly unlocked upon a rig-fire from a permanent ‘under-water basement’, its ‘water-sealed’ fire-escape entry serving as an exceptional model (‘Sumathi Paturu's ‘in-situ’ model’) for an ‘in-site’ fire-escape of a jack-up rig. An ‘off-site’ modular is an unlimited air-source for all ‘fire-escape’ units. A guarded ‘spray-room’ is a destination for ‘spray-walks’, or ‘spray-tracks’ with ‘track-drives’, or else simpler ‘spray-drives’—all being safe evacuation accessories workable with minimal cost and space. Wheeled ‘life-boats’ and ‘lift-boats’ protected against collision injury, are let out boarded/un-boarded by a remote control. Vital needs like safe evacuation, fresh air, and first-aids are devised as affirmed provisions. Other gas-fire protective outdoor/indoor measures include: ‘gas-chasing’ surface grid of fans and sprinklers about tall structures; similar grid ‘arching’ over the rig; and ‘gas-chasing’ pressured air-circuiting into the rig's interiors.
