Hydraulic Accumulator Charge Sensing

In sub-sea applications used for mining oil and gas at the ocean floor, large and powerful hydraulic accumulators often get the job of providing emergency power on blow out preventers positioned on the sea floor. If you’re a hydraulic accumulator manufacturer then you know that it’s all about pre-charge pressure. Accumulators are pressure vessels used to store hydraulic energy by compressing a blanked of nitrogen over an oil filled area. The accumulators are typically cylindrical type,

The Challenge of Subsea Position Sensing

One of the more challenging Hydraulic applications in the world exists far below the ocean, on the sea bed to be exact. A place where mother nature and the laws of entropy conspire to make all man made contraptions suffer, and challenge the ingenuity of engineers and scientists on a daily basis. One such contraption is the large piston based hydraulic accumulators used in undersea mining and drilling operations as part of critical blowout preventer systems.
