Heave Compensation Systems for Offshore Drilling

As oilfield engineering enjoys a resurgence of interest and investment, companies continue to look to advancements in technology to both reduce costs, and improve the safety of offshore drilling operations. In particular, active heave compensation systems use advanced hydraulic cylinders… Continue reading Heave Compensation Systems for Offshore Drilling

A New Angle On Linear Position Sensing

Those of you following our blog for the last few years, already know a few things about our linear position sensor products: They are based on a sophisticated re-implementation of the draw-wire class of linear position measurement systems, proven in… Continue reading A New Angle On Linear Position Sensing

Marine Riser and Tensioner System Hydraulics.

While CPI’s robust linear position sensor technology works great to report absolute cylinder position under the most demanding of conditions, it also has great application as a gauge of pre-charge pressure in a hydraulic accumulator. And perhaps nowhere is the… Continue reading Marine Riser and Tensioner System Hydraulics.

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… Continue reading Hydraulic Accumulator Charge Sensing

Draw Wire Sensors Revisited

In ancient times when cave men were trying to measure the linear displacement of things they cleverly came up with something called a “String Pot”.  Using only stone knives and bearskins, they were able to cobble together a spool with… Continue reading Draw Wire Sensors Revisited

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,… Continue reading The Challenge of Subsea Position Sensing

Really Big Hydraulic Cylinders Are Cool…

For those of us engineering types who derive particular enjoyment from an understanding of how big machines work, one of the most awe inspiring things to understand is the power achievable through large scale hydraulic cylinders. Being a unique supplier… Continue reading Really Big Hydraulic Cylinders Are Cool…
