    Abstract: Disclosed are processes and systems for preventing overpressurization of piping transporting fluid produced from a pressure source to a receiving facility in which the fluid passes through a high integrity pressure protection system (HIPPS). A relief device is provided in the piping in fluid communication with the HIPPS. In the event that fluid passing through the HIPPS during the valve closure time period has a property exceeding an activation property, the relief device is activated thereby allowing the fluid passing through the HIPPS during the valve closure time period to flow to a fluid containment volume. The fluid containment volume has sufficient volume such that upon the start of the closure of the valve in response to the pressure surge, a portion of the fluid passing through the HIPPS during the valve closure time period is absorbed by the fluid containment volume thereby lessening pressure increase in the piping.

    Abstract: Disclosed are processes, devices and systems for preventing overpressurization of subsea production equipment and flowlines in which fluid passes through a high integrity pressure protection system (HIPPS). In embodiments, a container having a piston seal therein can be attached to the piping. In embodiments, a device having a piston seal therein and connected to a fluid receptacle can be attached to the piping. In the event of a pressure surge, fluid can be diverted to the container or the device, thereby lessening the pressure surge. In embodiments, the container or device includes a resetting force to return the piston seal to its original sealed position. The use of the systems disclosed improve the life of the HIPPS valve, protects subsea equipment and flowlines, and enables a length and/or a wall thickness of a fortified pipeline zone downstream of the HIPPS to be reduced.

    Abstract: Methods and systems for controlling the timing of a fluid driven positive displacement pump (FDPDP) are disclosed using pump inlet pressure, flow rate and time domain control. Pressure is thus controlled at various flow rates of fluids to be pumped in subsea environments. The FDPDP includes a plurality of pressure vessels connected by piping, each vessel having two chambers. One chamber is connected to a source of fluid to be pumped and the other chamber is connected to a source of driving fluid. The methods synchronize pumping chambers that have no mechanical means to control timing between each pumping chamber. The control methods described utilize algorithms which receive feedback from the pumping system to control the pumping sequence and adapt to any parameter changes to maintain a constant range of desired pressure.
