摘要： Embodiments relate generally to systems and methods for decommissioning a pipeline. The system may comprise a mechanical assembly and chemical assembly. The mechanical assembly may include a main body and contact assembly. When the mechanical assembly is provided in the pipeline, the contact assembly is configurable to contact with the pipeline's interior wall. The chemical assembly may be arranged serially in line with the mechanical assembly. The chemical assembly may include a front section having a cross-sectional portion configurable to resemble the cross-section of the pipeline. The chemical assembly may also include a rear section having a cross-sectional portion. The front and rear sections may be arranged in such a way that, when the chemical assembly is provided in the pipeline, the cross-sectional portions of the front and rear sections cooperate with the pipeline's interior wall to form a chamber operable to receive and house a removal medium.

摘要： The present invention provides a method and a machine-learning system for predicting pipeline corrosion. The pipeline corrosion prediction according to the method and system comprises steps of i) generating a predictive model (100) based on a neural network algorithm; ii) applying a supervised machine learning technique for training the predictive model (100) from step i); and iii) applying the predictive model (100) from step ii) to other sets of the input data in order to predict a depth of metal loss rate (122). The predictive model (100) includes multiple modules relevant to a water condensation rate module, a flow regime module, a corrosion rate module, and an operating data module. Each module is integrated into a concatenate layer (114) and then processing through hidden layers (116), a long short-term memory layer (118) and hidden layers (120) respectively, in order to generate the depth of metal loss rate with high accuracy.

摘要： This invention relates to a completion plug for well completion, comprising:
A first attaching means (204) located between the upper part of a running tool (100) and a safety mean (200);
A second attaching means (304) located between the middle part of the running tool (100) and a shearing mean (300);
A third attaching means (422) located between the lower part of the running tool (100) and an equalizing mean (400) having an equalizing port (430) inside it;
Wherein, in one embodiment, the completion plug is configured to equalize the well pressure by releasing the first attaching means (204) so that the equalizing shear sub (202) will reduce impact force between the equalizing means (400) and the inner of the running tool (100); and wherein the second attaching means (304) releases the running tool (100) to press an equalizing prong housing (450) connected to the lower end of the running tool (100) down in order to open the equalizing port (430) for equalizing pressure between the upper and the lower of the well.
In another embodiment, the completion plug is configured to close the well by releasing the first attaching means (204) so that the equalizing shear sub (202) will reduce impact force between the equalizing means (400) and the inner of the running tool (100); and wherein the third attaching means (422) releases the equalizing means (400) from the running tool (100) in order to make the bottom sub (500) close the well when the well is not in use for production.

摘要： Embodiments relate generally to a turret system for use in a floating vessel. The turret system may comprise a turret body and windlass subsystem. The turret system may comprise top and bottom surfaces, first and second mooring line storage sections, and first and second mooring line channel sections. Each mooring line storage section may include an opening and cavity. Each opening is operable to receive a mooring line. The first and second mooring line channel sections may be separate elongated passageways for first and second mooring lines, respectively, to be directed through the turret body and an exterior of the floating vessel without coming into contact with one another. The windlass subsystem may comprise a rotatable member, and configured to be transportable between locations. When the windlass assembly is configured to be secured to the turret body, the windlass assembly is configurable to control a movement of a mooring line.
