Abstract: A subsea valve system for use in a subsea landing string includes a subsea valve and an external manifold in fluid communication with the subsea valve. The external manifold includes a cylinder, a split manifold piston, an above bore inlet that is configured to be exposed to an above bore pressure, a below bore inlet that is configured to be exposed to a below bore pressure, and an open chamber outlet. The split manifold piston is configured to move within the cylinder to fluidly couple the above bore inlet to the open chamber outlet to enable pump through functionality while a respective force exerted on the manifold piston by the above bore pressure is greater than a respective force exerted on the manifold piston by the below bore pressure.

Abstract: Apparatus and methods for filling a pressure compensated fluid container with a liquid. An example method includes restraining movement of a piston slidably disposed within the fluid container in a first piston position, wherein the piston divides the fluid container into first and second portions. The method further includes pumping the liquid into the first portion to compress gas located within the first portion, stopping the pumping of the liquid into the first portion, and stopping the restraining of movement of the piston to permit the piston to move to a second piston position due to expansion of the gas compressed within the first portion.

Abstract: A game executed on a data processing system receives one or more prediction selections from participants of possible outcomes expected for an event such as a sports game. Data regarding the event (e.g., historical data) is stored in a database or other form of data storage in memory. At least one of the prediction selections received from the participants is provided after the start of the event. A plurality of prediction factors are stored, and a model including one or more rules uses the plurality of prediction factors. During the event, participants are provided with actual results from the event that are related to the prediction selections of the participants.
