Abstract: Aspects of the present disclosure relates to methods of making a hybrid mechanically lined pipe, and apparatus thereof, such as lined pipe used for reeled pipe operations. In one implementation, a method of making a lined pipe for reeled pipe operations includes determining a minimum weld overlay length for a first pipe joint, and providing the first pipe joint. The first pipe joint includes a first end opposite of a second end, a central opening, and an inner surface. The method includes mechanically lining the inner surface of the first pipe joint with a first section of alloy. The method also includes weld overlaying a second section of alloy and a third section of alloy in the central opening and on both sides of the first section of alloy over the minimum weld overlay length to prevent excessive deformation of the mechanically bonded section during reeling operations.

Abstract: Aspects of the present disclosure relates to disruptive coupling systems and methods, and apparatus thereof, for subsea systems. The subsea systems may be subsea oil and gas systems. In one implementation, a subsea system includes a subsea component disposed in seawater, and a disruptive coupling device coupled to the subsea structure and/or surrounding fluid.
