Title:
EMERGENCY DETACHABLE ISLAND RIG AND FIRE ESCAPE
Document Type and Number:
WIPO Patent Application WO/2017/078746
Kind Code:
A8
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.
