Abstract

See full text

Systems and methods for controlled equalization of fluid pressure are described. The system can include a flow restricting nozzle in line with an accumulator which together provide a gradual, controlled equalization of pressure between two locations. For example, in the subsea environment, the pressures can vary between a subsea processing station and a subsea flow line. The systems can be configured as ROV retrievable, or they can be integrated into the subsea processing station. In some cases, more than one accumulator and/or more than one flow restricting nozzles can be used in the system to provide for versatility and robustness.
