OFFSHORE SYSTEMS AND METHODS FOR LIQUEFIED GAS PRODUCTION, STORAGE AND OFFLOADING TO REDUCE AND PREVENT DAMAGE
First Claim
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; and
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 first pipe is adapted to cease fluid communication of hydrocarbon fluid between the mobile storage platform and the mobile offloading platform.

Abstract
Disclosed are systems and methods 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. An offshore platform arrangement includes a mobile offshore production unit (MOPU), a mobile storage platform and a mobile offloading platform which are disposed at a clearance distance from one another. The platforms are fluidly connected by pipes to allow hydrocarbon fluid transfer therebetween. The pipes are adapted to cease fluid communication of hydrocarbon fluid between platforms for preventing damage spread therebetween. Also disclosed is an offloading system for hydrocarbon fluid transfer which includes a lifting system having an extendable lifting arm and a spreader frame platform rotatably coupled to the lifting arm. The spreader frame platform is operable to support a transfer skid and allow angular adjustment of the transfer skid in a horizontal plane.
