Abstract
A mooring buoy system releasably connects risers and anchor lines to a turret of a floating structure, and includes: a buoyant body carrying the risers, which extend to a subsea hydrocarbon well; anchor line connectors, for connecting anchor lines to the buoyant body, each anchor line having one end connected to a connector and the opposing end to the seabed; and a reconnection wire running through a channel coinciding with a center line of the buoyant body, connectable to each anchor line below the buoyant body at some distance from the anchor line connectors through anchor line connection sections on one end and includes a stopper and winch wire connection arrangement on the other end. Also disclosed is a method for pulling up risers and anchor lines, for releasably attaching the risers and anchor lines, as well as a method for constructing a mooring buoy.
