Abstract:
1. An offshore system for limiting structural damage to an affected offshore platform and preventing damage spread from the affected offshore platform to another platform during an accident or an emergency condition, comprising: a mobile storage platform having a hydrocarbon storage facility; a mobile offloading platform disposed at a first clearance distance from the mobile storage platform and having an offloading system for facilitating transfer of hydrocarbon fluid from the hydrocarbon storage facility to a carrier vessel which is positioned at the mobile offloading platform; at least a first pipe connecting the mobile storage platform to the mobile offloading platform for allowing fluid communication of hydrocarbon fluid therebetween, wherein the at least first pipe is adapted to cease fluid communication of hydrocarbon fluid between the mobile storage platform and the mobile offloading platform; a mobile offshore production unit (MOPU) having a production facility, wherein the mobile offshore production unit is disposed at a second clearance distance from the mobile storage platform; and at least a second pipe connecting the mobile offshore production unit to the mobile storage platform for allowing fluid communication of hydrocarbon fluid therebetween, wherein the at least second pipe is adapted to cease fluid communication of hydrocarbon fluid between the mobile offshore production unit and the mobile storage platform, wherein each of the mobile storage platform and the mobile offshore production unit includes a plurality of jack-up legs installed into a sea floor such that the mobile storage platform and the mobile offshore production unit are fixed bodies which are unaffected by wave motion, wherein the at least first pipe and the at least second pipe are located above the sea level, and wherein the mobile offloading platform includes
