SYSTEM AND METHOD FOR HEADING CONTROL OF A FLOATING LNG VESSEL USING A SET OF REAL-TIME MONITORED HULL INTEGRITY DATA
First Claim
1. A system for offshore production of LNG from an FLNG vessel, which system is connected to a natural gas receiving system, the system comprising:
- a floating LNG vessel comprising a hull and a deck;
a topsides hydrocarbon processing facility installed at or above the deck of the hull of the FLNG vessel;
an FLNG vessel cargo containment system comprising one or more insulated FLNG vessel cryogenic storage tanks installed within the hull of the FLNG vessel;
a dynamic positioning control system operatively associated with a system of thrusters onboard the FLNG vessel wherein the dynamic positioning control system maintains the FLNG vessel at a desired heading around a station keeping point during LNG production operations; and
,a computer processor for receiving a set of real-time monitored environmental data, wherein the computer processer is programmed with a mathematical algorithm to;
(i) compare the set of real-time monitored environmental data to a set of stored set points held in a data storage means;
(ii) generate a heading control correction signal when the set of real-time monitored environmental data exceeds or falls below one or more of the set of stored set points for the FLNG vessel; and
(iii) transmit the heading control correction signal to the dynamic positioning control system;
wherein the set of real-time monitored environmental data includes a set of real-time monitored hull integrity data associated with a level of strain experienced by the hull of the FLNG vessel, and the set of stored set points held in the data storage means includes a set of hull integrity set points.
