Abstract: Disclosed are methods, systems and computer readable storage media which facilitate the design of cables and pipes, including umbilicals, flexible pipes, optical cables, power cables, composite pipes, bundled pipes and combinations thereof. In one aspect, a computer implemented method includes, in response to input from a user in a plug-in interface in a graphical user interface within a computer-assisted design program, in a processor, executing instructions for receiving design information from a computer-assisted design program as well as receiving loading and deformation information from a global analysis software package for a cable or pipe having multiple components. A model is created using the design, loading and deformation information. The model is readable by a cable or pipe analysis software package. Thus the user is not required to manually generate the model of the cable or pipe readable by the cable or pipe analysis software package to be input into the cable or pipe analysis software package.

Abstract: Disclosed are systems for securing a bend stiffener to a riser in an offshore energy production facility. In one system, the lower end of the bend stiffener has a magnet that repels a magnet in a clamp on the riser a distance below the bend stiffener. The magnets repel one another with a force during operation to decelerate falling and prevent contact between the clamp and the bend stiffener. Methods are provided for retrofitting a riser system by adding the magnets. In another system, the riser has an upper portion and a tapered portion immediately below the upper portion. The outer diameter of the tapered portion increases such that the tapered portion can be friction fit into the lower end of the bend stiffener in the event that the bend stiffener is forced down or free falls onto the riser.

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.
