Abstract: In-riser power generation devices and methods are utilized to generate power subsea to operate subsea devices of a subsea well system. A turbine power generator is located in fluid communication with a subsea fluid flow path of a subsea well system and the turbine power generator is operationally connected to a subsea power device.

Abstract: A technique facilitates monitoring of strain related effects along a tubing string, such as a tubing string extending from surface equipment toward a sea floor in a subsea well application. A monitoring module is employed to monitor the strain related effects and may have a tubular structure. The monitoring module also has a reduced wall thickness region constructed to concentrate strain in this reduced wall thickness region. Additionally, the monitoring module comprises at least one sensor mounted to the tubular structure in the reduced wall thickness region for monitoring of strains.

Abstract: A piping system for housing system components for regulating the flow of fluid therethrough is provided. The piping system includes an inner small diameter length of piping through which hot fluids flow, an outer larger diameter length of piping surrounded by cold fluid, and an annulus between the small and larger diameter piping in which the system components are received. Insulation material extends about a predetermined section of the small diameter length of piping for restricting heat transfer therefrom to the system components in the annulus and allowing heat transfer from the system components in the annulus to the outer piping.

Abstract: An apparatus includes an engagement device to be disposed on a landing string. The engagement device includes a retracted state to allow the apparatus to be run inside a riser and an expanded state to engage the riser to secure the apparatus to the riser. The apparatus further includes an actuator assembly to be disposed on the landing string. The actuator assembly is remotely actuatable from a sea surface to rotate a tubing of the landing string relative to the engagement device to rotate the landing string to orient a tubing hanger assembly.

Abstract: A method is disclosed to purify a polymeric material by filtering a melt comprising poly(arylene ether) and poly(alkenyl aromatic) through a melt filtration system. The method provides a filtered polymeric composition having reduced levels of particulate impurities. The filtered polymeric composition prepared is suitable for use in data storage media applications.

Abstract: In one embodiment, a disc has a substrate; a data layer on the substrate; an anomaly-feature in the data layer disc capable of generating a read anomaly having a predictable anomaly profile; and anomaly profile data recorded in the data layer for characterizing the anomaly-feature. A disc can be labeled by imposing an anomaly-feature in the data layer capable of generating a read anomaly having a predictable anomaly profile; and disposing anomaly profile data on the disc, wherein the anomaly profile data characterizes the anomaly-feature.
