Abstract:
Disclosed are various to blockage remediation systems for removing blockages, e.g., hydrate plugs, debris plugs, etc., from subsea flowlines and subsea equipment. In one illustrative embodiment, the system includes, among other things, an ROV ( 102 ) deployed into a body of water from a surface vessel ( 10 ) and a blockage remediation skid ( 104 ) that is operatively coupled to the ROV ( 102 ), wherein the skid ( 104 ) includes at least a skid fluid inlet ( 108 A) and a skid fluid outlet ( 106 A). The system also includes a returns downline ( 106 ) and a pressurized lift-gas supply downline ( 108 ) that extends into the body of from the vessel ( 10 ). The returns downline ( 106 ) is operatively coupled to the skid fluid outlet ( 106 A), while the pressurized lift-gas supply downline ( 108 ) is adapted to be operatively and directly coupled to the blockage remediation skid ( 104 ) or operatively and directly coupled to the returns downline ( 106 ). The system also includes a remediation flow line ( 110 ) that is operatively coupled to the skid fluid inlet ( 110 A) and a flowline ( 16 ) or an item of subsea equipment ( 12, 15  or  17 ).

Claim (Index 13):
The system of  claim 1 , further comprising:\n a first valve ( 132 - 1 ); a second valve ( 132 - 2 ), and a third valve ( 132 - 3 ), wherein the first ( 132 - 1 ), second ( 132 - 2 ) and third ( 132 - 3 ) valves are configurable so as to define at least the following fluid flow paths;\n a first flow path established by opening the first ( 132 - 1 ) and second ( 132 - 2 ) valves and closing the third ( 132 - 3 ) valve, whereby pressurized lift-gas ( 108 X) may flow down the pressurized lift-gas supply downline ( 108 ) and into the remediation flow line ( 110 ) while the returns downline ( 106 ) is closed; \n a second flow path established by opening the first ( 132 - 1 ) valve and the third ( 132 - 3 ) valve, whereby a production fluid ( 115 ) from the flowline ( 16 ) or the item of subsea equipment ( 12 ,  15   17 ) is received into the remediation flow line ( 110 ) may flow into the returns downline ( 106 ) while the pressurized lift-gas supply downline ( 108 ) is closed; and \n a third flow path that is established by opening the second ( 132 - 2 ) and the third ( 132 - 3 ) valves and closing the first valve ( 132 - 1 ), whereby pressurized lift-gas  108 X may flow down the pressurized lift-gas supply downline ( 108 ) and into the returns downline ( 106 ) while the remediation flow line ( 110 ) is closed.
