Abstract:
1. A system for deploying a deepwater mooring spread from a floating vessel with a hold and deck, using a aft crane secured to a port side or a starboard side of the floating vessel, and a fore crane secured to the port side or starboard side of the floating vessel, comprising: a. at least two suction piles and a suction pile anchor chain, at least two lift slings, at least one pad eye for each lift sling, a first remote operated shackle connected on the top of the suction pile and at least one side pad eye connecting the suction pile anchor chain to the suction pile, and a remote operated connector disposed on the top of the suction pile, wherein each suction pile is disposed in the hold or on deck of the floating vessel; b. a load bearing structure connected to an outboard port side or an outboard starboard side of the floating vessel; c. a hang-off connected to the load bearing structure for supporting polymer lines connected in series; d. a reel drive fixedly secured to the load bearing structure for deploying at least one polymer line; e. at least one buoy for each suction pile, wherein each buoy has a buoy chain; f. at least one deepwater deployment system for one of the cranes, wherein the at least one deepwater deployment system is secured in the hold enabling at least one crane to lower the crane's main block to water depths of at least 1000 meters; and g. a plurality of remote operated connectors for: (a) engaging the first polymer line to the suction pile, (b) engaging the first polymer line to a hang-off and then a chain segment, (c) engaging the chain segment to a first end of a second polymer line, and (d) the second end of the second polymer line to the hang off or another chain segment.
