2H’s structural monitoring and data analysis experts recognise all the critical aspects involved in structural monitoring systems. We maintain a practical view and have a sound understanding of monitoring equipment options, installation drivers, and the operational needs of the client.

We provide structural monitoring services for a variety of offshore oil, gas and renewable assets. This includes wellhead and conductor systems, production and drilling risers, subsea jumpers, flowlines, umbilicals, and fixed and floating wind turbines. We have developed more than 500 structural monitoring programs for our clients all over the world.

Not only have our field data analysis results been used by clients to verify the structural integrity of their assets during extreme environmental conditions, but they have also helped us calibrate the analysis tools and to improve design assumptions for future developments. This has led to considerable cost benefits for our clients.

Monitoring System Specification

Developing an effective monitoring program requires an in depth understanding of structural system response to know how best to capture the data. Depending on our client’s monitoring objectives and budget, we recommend one of three data communication methods, i.e., standalone, hardwired, or acoustic. Next, we carefully specify the appropriate number of sensors, their locations, accuracy and sensitivity, equipment attachment method, and installation procedure.

Procurement & Installation

We will help identify the most appropriate monitoring system supplier and equipment based on our client’s monitoring requirements. In many cases, the monitoring equipment is available off-the-shelf and field proven. However, for unique monitoring objectives, we can witness and evaluate qualification testing of customised equipment. We also have experienced personnel who can oversee offshore installation.

Data Analysis & Management

We verify and analyse data quickly and reliably thanks to a suite of automated in-house tools which provide sensor data quality checks and data screening results in time and frequency domain. State-of-the-art, proprietary algorithms are used to calculate the fatigue accumulations of the offshore structures for the monitoring period.
