Abstract
A subsea drilling system with a subsea component controllable by a fluid supply source. The system includes a pressure dampener in fluid communication between the fluid supply source and the subsea component. The pressure dampener includes a body consisting of a dampener fluid flow path which consists of a volume and a biasing system. The biasing system includes a piston biased to an initial position, wherein the piston is configured to move from the initial position to expand the volume of the dampener fluid flow path and dampen a pressure surge received by the pressure dampener and wherein the biasing system is configured to contract the volume of the dampener fluid flow path by returning the piston toward the initial position after dampening the pressure surge.
