Abstract: The present embodiments disclose a system and method for generating a predictive model to detect leak in undersea pipes. The system includes an administrator processor and one or more pipe sections. The method proceeds with observing changes in pressure, generating a predictive model configured to determine if a leak has occurred, and closing one or more pipes responsible for the leak.

Abstract: An artificial cable trench (ACT) includes a body and a trench formed into the body. The trench is configured to hold a cable, umbilical, or similar feature. The ACT may be positioned along a seabed or shoreline to stabilize the cable and thereby prevent movement and eventual damage to the cable. The body of the ACT is shaped to overcome the flow induced loads caused by the relative motion between the cable and the surrounding waves and sea currents as well as providing effective friction/engagement with a contact surface (e.g., a shoreline surface). The ACT may have features that result in self-burying in sand and/or preventing lateral movement.

Abstract: Disclosed are systems and methods for thermal management of subsea conduits. A jumper that carries oil and/or gas produced from a subsea well in a subsea production facility located on a seabed has a first end for connecting to a first subsea component and a second end for connecting to a second subsea component. The jumper includes a jumper segment that is sloped relative to the horizontal, such that gravity assists with drainage of fluid from the second end of the jumper independent from fluid pressure in the jumper. At least a portion of the jumper is uninsulated to allow exchange of heat with seawater surrounding the jumper as produced fluid travels through the jumper. The amount of insulation on the jumper can be varied such that heat transfer from the production fluids to seawater surrounding the jumper circuit is adjusted as desired.
