An assembly comprising an end-fitting for terminating an unbonded flexible pipe and an unbonded flexible pipe

摘要

The present invention relates to an assembly comprising an end-fitting (10) for terminating an unbonded flexible pipe (1) and an unbonded flexible pipe (1). The unbonded flexible pipe (1) comprises a first (2) and a second (4) armour layer co-axially arranged, and an electric heating system The end-fitting (10) comprises means (22) for mechanically anchoring the first armour layer (2) to the end-fitting (10) and comprises electrical connections for connecting the first armour layer (2) to a power-source. The end-fitting (10) also comprises means (24a, 24b) for mechanically anchoring the second armour layer (4) to the end-fitting (10). The first (2) and second (4) armour layers are electrically insulated from each other by at least one electrically insulating layer (3) in the end-fitting (10) and the end-fitting (10) comprises a local volume (35) in the end-fitting (10) adjacent to the electrically insulating layer (3) adapted for injection of a functional fluid.
