offshore riser monitoring system

Riser Monitoring System Engineering

Over 500 monitoring systems delivered

Our riser monitoring experts recognise all the critical aspects involved in implementing a subsea structural monitoring system and will design the most appropriate monitoring system and programme for your asset.

We have designed and implemented over 500 structural monitoring systems for a variety of subsea structures including riser systems, subsea jumpers, flowlines, umbilicals, and wellhead and conductor systems. These have been used to evaluate strength and fatigue performance, as well as calibrate analysis tools and models. The knowledge gained from these monitoring programs has also enabled us to improve our own design methods, which has led to considerable cost benefits for our clients.

Riser Monitoring System Specification

Effectively monitoring dynamic offshore structures like risers requires a good understanding of system response in order to capture enough data for meaningful interpretation. We carefully select the appropriate number of instruments, their locations, accuracy and sensitivity, and the best methods of data communication methods, equipment attachment and installation for your project’s requirements and budget.

Data Processing & Management

2H can process data from our systems that we have designed or from existing systems. We verify and process data quickly and reliably thanks to a suite of automated tools developed in-house that provide sensor data quality checks, time and frequency domain data processing and fatigue analysis for stand-alone, acoustic and hard-wired systems. State-of-the-art, proprietary algorithms are used to calculate the fatigue damage of riser and subsea systems from both wave and current induced motions.
