A method of laying a subsea pipeline from a reel, the pipeline having an in-line first locking member, the method having at least the steps of: (a) laying the pipeline under the water from the reel; (b) cutting the pipeline above the first locking member; (c) coupling the first locking member with a complementary second locking member; and (d) lowering the first and second locking members under the water. In this way, the pipeline already has located within it a suitable locking member for the abandoning operation, avoiding the need for a separate off-shore welding operation.
