Abstract: The invention encompasses fire-escape models of off-shore rigs with emphasis on a 'Detachable Island Rig' (DIR.) instantly unlocked upon a rig-fire, from a permanent 'under- water basement', saving property and personnel. The devised 'water-seal' of its basement's 'in-situ' 'fire-escape' entry, not destroyed upon a rig-fire, serves as an exceptional model (named 'Sumathi Paturu in-situ model', after its inventor) for an 'in-site' fire-escape with similar 'water-seal' for jack-up rigs with no basements. An 'off-site' modular is an unlimited air-source for all 'fire-escape' units. A 'spray-room' with converging 'spray-walks', or 'spray-tracks' with 'track-drives' or else a simpler means of 'spray-drives' are safe evacuation accessories workable even with minimal expendable cost and space. In the foregoing, vital needs like safe evacuation, food, and fresh air are devised as affirmed provisions. The wheeled 'life-boats' and 'lift-boats' are let out boarded or un-boarded, by click of a remote control, with no sustainable collision injury.

Abstract: The invention encompasses fire-escape models of off-shore rigs with emphasis on a 'Detachable Island Rig' (DIR). The DIR unlocked from permanent underwater basement, is steered away by 'steering crew' upon rig-fire, saving working amenities. The basement's fire-escape (for the rest of the crew) with devised 'water-seal', not destroyed upon rig-fire, serves as a model to create 'water-seal' for jack-up rigs. An 'off-site' modular is unlimited air source for all 'fire-escape' models. Converging 'spray- walks' to a 'spray-room', 'spray-tracks' with 'track-drives', or simpler 'spray-drives' are safe evacuation accessories workable with minimal cost/space. Other indoor/outdoor gas-fire protective measures include 'gas-chasing' surface grid of fans and sprinklers about tall structures and gas-chasing pressured air-circuits about rigs'interiors. The wheeled 'life-boats' and 'lift-boats' are let out boarded/un-boarded by a remote control, without 'collision' injury. Vital needs like safe evacuation and fresh air are herein devised as affirmed provisions.

Abstract: Catastrophic events involving oceanic petroleum oil-wells are threats to ventures in this intriguing avenue. This invention of exemplary models working in synchrony are directed to emergency responsive and reparative measures to weather through the adversities of such deep sea explorations, thereby restoring/preserving the functioning of the well structure, involving - An 'incomplete oil-well ' with disrupted 'production casing', its dimensions sealed by an 'EMERGENCY PNEUMATIC SEALING ENSEMBLE', further incorporating an oil-outlet, OR a 'completed oil-well' with fractured 'production tubing', its dimensions sealed by a pneumatic 'EMERGENCY PLUGGING OIL-CONDUIT' - both stabilized by a 'stabilizing unit' about the well head. Reparative cement-structuring an 'EMERGENCY ISOLATION PLATFORM' incorporating functional well-head structures. All tubing of the well-rig unit, to have threading throughout, to articulate with 'INSTANT JOINT STRUCTURES' shaped as I, T, U etc. having complimentary threading for joining broken tubular system; 'STURDY CLOSING CAPS', to instantly close broken tubular system.

Abstract: The modular 'Sea Level Gas Separators of Oil Well Effluent' (SLGOE) units about a rig vicinity preclude gas entrainment reaching the rig. When operative as an 'Emergency operational SLGOE unit' (EOS unit), functional only after a blow-out, the effluent is let out from annulus A into 'gas-separator' tanks of EOS unit, entering as a down-flow, whereby instantaneous separation of gaseous elements is effectuated, with the massive top outlets letting off the rising gas, furthermore attenuating its pressure, the pressure and volume being inversely proportional. When operative as a Multi-operational SLGOE unit (MOS unit), the unit separates the effluent on regular basis, and also after a blow-out. In either model, a gas entrainment by its instantaneous ascent, is precluded from entraining into down-streaming oil. When the drilling conductor is breached, an 'oil separator' tank separates oil from admixed water, whereby pollution of oceanic water is precluded.

Abstract: The devised modular of 'Subsea Level Gas Separator of Oil Well Effluent (SLGOE) precludes giant gas entrainment entering the rig. The effluent, past the BOP, is diverted by gravity through a 'diversion' tube, into the bottom of 1-3 'gas separator' tanks, creating fountain-like flow. The downstream, syphoned from an 'oil passage tank', joins the partitioned collection system past the 'diversion' tube. The large top outlets of 'all' tanks let off 'instantly' rising gases. In another embodiment of two 'gas separator' tanks, oil flows from the top of the first. Its bottom outlet directs it into the top of the second. From it, oil is siphoned to the collection system. The large top outlets of both tanks instantly let off gases. In either device, the gas 'instantly' separates from the effluent tossed into aerial milieu of the tanks, a simplest model conceivable, the laws of nature taken advantage of.

Abstract: The invention describes a schematic 'Detachable Island Rig' (DIR) locked on immovable basement, to be detached upon an oceanic rig-fire. For stationing back onto the basement, always submerged in water, the DIR is pulled down by pulleys on the sides of the base structure. The basement 'accessed' from within DIR or from outside, through the roof or from top side windows of a staircase-room erected from the basement, to rise far above ocean waters, is an optional fire-escape. A 'fire escape', with plan similar to the basement 'access', can be constructed as a 'modular' unit. The 'modular' with a roomy enclosure and narrow towering top, is chained to the rig, and schemed for always maintaining safe distance. It floats with finite number of helium sacs when unoccupied, but attains fire-inaccessible safe submersion when occupied, by blowing out finite number of helium sacs proportional to the added weight.
