Abstract: A subsea pipe for filtering a fluid produced during a subsea field operation can include a housing having a housing wall forming a cavity, where the housing has an upstream end and a downstream end that define a length of the housing. The subsea pipe can also include a filter disposed within the cavity along the length, where the filter defines a first flow area and a second flow area within the cavity. The upstream end can be configured to receive the fluid in an unfiltered state from an upstream subsea pipe into the first flow area within the cavity, where the downstream end is configured to distribute the fluid in a filtered state from the second flow area in the cavity to a downstream subsea pipe, and where the filter is configured to remove solids as the fluid passes through the filter.

Abstract: A machine-learning model is trained using images of structures including defects and images of structures not including defects. Preprocessing is performed on the images before training the machine-learning model. The trained machine-learning model is used to classify defects within images of structures. Images of structures with defects are identified, and the probabilities of the identification/defect classification are obtained.

Abstract: Disclosed is an apparatus for sealing and severing a subsea pipe adapted to convey fluids, e.g., hydrocarbons, and systems and methods using such apparatus. The apparatus includes a housing adapted to attach to the pipe, a piercing tool for providing an opening in the pipe at a predetermined location and a mechanism for establishing fluid communication between a source of sealant material and space within the pipe adjacent the opening in the pipe, and a cutting mechanism for cutting the pipe. Methods disclosed include piercing the pipe to form an opening, injecting sealant material through the opening into the pipe to form a fluid-tight seal, and cutting the pipe through the seal to form sealed cut ends.
