A MOONPOOL PLUG FOR CONNECTING A FLEXIBLE FLOWLINE TO A PROCESS VESSEL Abstract A buoyant moonpool plug 30 for connecting subsea flowlines 16 to a surface vessel comprises an elongated plug shell 31 which is adapted for being drawn into a vessel moonpool and within which are defined a plurality of elongated buoyancy tanks 33, 34. Central support means 42 serve to releasably attach the moonpool plug 30 to a turret of said vessel moonpool for rotation therewith and an internal plug support structure is provided for attaching the central support means 42 to the plug shell 31 at an upper portion of the plug shell 31. A plurality of guide tubes 35 are connected to the internal plug support and are disposed in radial array around the central support means 42, the guide tubes 35 extending through the plug shell for housing the subsea flowlines 16. To disconnect the flowlines 16 from the vessel a positive buoyancy is established for the plug 30 which is substantially less than the negative-buoyancy of the flowlines and the plug is then released from the surface vessel, thereby permitting the plug to be fully submerged to a balanced buoyancy position supporting the flowlines in lowered catenary arrangement.
