The invention encompasses fire-escape models of off-shore rigs with emphasis on a ‘Detachable Island Rig’ (DIR) with a bottom air capsule. The DIR unlocked from permanent underwater basement, is steered away upon a rig-fire, while also sinking and rising the unit controlling a fire. The basement's fire-escape for the crew with devised ‘water-seal’ also serves as fire-escape model for Jack-up rigs. Converging ‘spray-walks’ to a ‘spray-room’, ‘water-tracks’ with ‘track-drives’, or simpler ‘spray-drives’ are evacuation accessories. Other gas-fire protective measures include gas-chasing fans and pressured air-circuits, while canisters of soda lime absorb CO2 and CO. The wheeled ‘life-boats’ and ‘lift-boats’ are remotely let out boarded/un-boarded without collision injury. Strut-burlaps air-dropped from hovering cranes, drones or helicopters can smother a rig-fire. Countering devising for water-wind turbulences is herein actuated for floating rigs without legs. Vital needs like safe evacuation and fresh air supply are herein devised as affirmed provisions.
