A method of calibrating a laser of an additive manufacturing system involves processing a test pattern with the laser while varying one or more of laser power and/or scan speed. Thermal energy emitted from the resulting meltpool is measured while processing the test pattern. The power of the laser is calculated using a relationship between volumetric energy density and the thermal emissions, and the laser power is adjusted based on the calculated laser power. An additive manufacturing system for performing such a method may include a laser, a thermal sensor configured to measure meltpool thermal emissions, a processor configured to calculate a laser power based on the measured meltpool thermal emissions of the test pattern, and a controller configured to adjust the laser power based on the calculated laser power.

A valve assembly for managing a flow of fluids in hydrocarbon development and production operations includes a valve body having an internal body cavity and a body bore intersecting the body cavity. A valve plug is located within the body cavity and is rotatable between an open position and a closed position. A sleeve is located between the valve plug and the valve body and is rotationally fixed to the valve body and remains rotationally static relative to the valve body as the valve plug rotates. A seal groove is located on a sidewall surface of the sleeve and circumscribes one of the sleeve openings. A seal assembly has a seal ring that is U shaped in cross section with an inner leg that engages the seal groove and an outer leg that extends out of the seal groove and engages one of the valve body and the valve plug.

The present invention provides an insulated fluid conduit useful in facilities in which a hot fluid susceptible to one or more deleterious phase changes in response to heat loss to a cold environment is transported. Such conduits may be particularly well suited to improve thermal control in subsea hydrocarbon production operations. The fluid conduit includes an inner first insulating layer containing a first polymer matrix, and a first phase change material undergoing a phase change at T. The fluid conduit includes an outer second insulating layer containing a second polymer matrix, and a second phase change material undergoing a phase change at T, wherein Tis greater than T. One or more barrier layers inhibit migration of the phase change material from the insulation layers and into the environment. In one or more embodiments, the phase change material is present as a microencapsulated phase change material.

A wellhead assembly having a tubular magnetized in at least one selected location, and a sensor proximate the magnetized location that monitors a magnetic field from the magnetized location. The magnetic field changes in response to changes in mechanical stress of the magnetized location, so that signals from the sensor represent loads applied to the tubular.

An acoustic modem located on a blowout preventer stack communicates with a running tool acoustic modem located on a subsea running tool disposed within a subsea wellhead, tree or tubing spool. The acoustic modem and the running tool acoustic modern transmit and receive acoustic signals through a column of fluid in the blowout preventer stack. The acoustic modem is communicatively coupled to a subsea electronics module located on the blowout preventer stack and further communicatively coupled to a central control unit located on a platform at the surface. The running tool acoustic modem is communicatively coupled to a controller that receives data from sensors on the running tool and sends operational signals to functions of the running tool. An operator at the surface may control the running tool through the acoustic modems, and the running tool may communicate the running tool status to the operator through the acoustic modems.

A seal seals an annulus in a subsea assembly between a wellhead and a casing hanger landed on a shoulder within a bore of the wellhead. The seal includes a casing hanger seal ring disposed within the annulus. The seal ring engaged with an inner diameter surface of the wellhead, and engaged with an outer diameter surface of the casing hanger so that the seal ring prevents flow through the annulus. A nose ring is secured to a lower end of the seal ring so that, when the seal ring is energized, a conical surface of the nose ring engages a mating conical profile formed in the inner diameter surface portion of the wellhead and the nose ring engages a surface opposite the conical surface with a substantially smooth outer diameter surface portion of the casing hanger to limit upwards axial movement of the casing hanger.

A wellhead assembly for use subsea includes a high pressure housing landed within a low pressure housing. The low pressure housing is an annular member that mounts into the sea floor and having an inner surface engaging the high pressure housing along a loading interface. Upper and lower sockets are formed along axially spaced apart portions of the outer surface of the high pressure housing. As the high pressure housing inserts into the low pressure housing, the high pressure housing sockets engage corresponding sockets formed along axially spaced apart sockets on portions of the inner surface of the low pressure housing. The sockets each have cylindrically shaped outer surfaces, and when engaged with one another define the loading interface. The sockets are strategically located on the upper and lower portions of the housings to maximize their distance apart.
