We assist in maintaining control of the current status of pipelines, risers, structures and wells. This is an essential part of safety and quality assurance, offshore.

Confidence through accurate and real-time monitoring

In order to maintain safety and ensure full continuous operation, it is vital to prevent excess utilisation of components. Strain, curvature, vibration, pressure, temperature and movement are all factors that affect the remaining service life of an asset. 

We hold more than twenty years of experience, and our solutions have all been field proven. Having our systems installed allows you to make more qualified decisions regarding utilisation and life extension, which can lead to considerable cost savings.

Replacement and unexpected shut-downs can be postponed and prevented. This provides increased operational reliability and safety, as well as prolonged service life, while at the same time meeting government requirements in a cost effective way.

We provide structural monitoring for:

  • Drilling & workover operations
  • Hybrid risers
  • Foundation & grouting
  • Jackets & structures
  • Displacement
  • Vibration subsea & EEx zone

Drilling and workover operations

During both drilling and workover operations, it is important to ensure that tension, bending moment and movement is kept at a bare minimum. We provide accurate monitoring of these factors, either continuously or as a part of an assessment.

For drilling operations, we arrange our sensors strategically in order to detect relevant loads, such as movement or VIV (vortex induced vibrations). During workover operations, we arrange sensor on the tension point and on the lower tapered stress joint and, if required, on the LRP (lower riser package) or EDP (emergency disconnect package).

We measure:

  • Tension
  • Bending moment
  • Shear force
  • Angle/Inclination
  • Accelerations

Current, waves and position may be added to our system, and we offer full redundancy.

Wellhead structural monitoring

To determine the tension and bending moment at the wellhead, we place sensors as far down as possible on the BOP connector, on the BOP, and on the flex joint. This provides an accurate measurement that allows you to assess the fatigue and remaining service life of the wellhead.

Hybrid risers

Hybrid risers consists of a combination of a tensioned steel riser and a flexible riser. We provide several approaches for monitoring of flexible risers (click here for more information on this), and we also provide a range of solutions for tensioned risers. These solutions may be combined to serve hybrid risers effectively.

Monitoring of tensioned risers includes monitoring of:

  • Tension
  • Position
  • Orientation

We provide permanent sensors or ROV retrievable replacement sensors, based on Hysens Technology. This may be coupled with batteries and hydro acoustic communication if there are no available cable solutions.

Foundation and grouting

Based on motion sensors and displacement, we provide a wide range of solutions for monitoring of foundation and grouting. The solutions are custom built to suit the purpose.

Jacket and structures

We provide systems for measuring both loads and structural response on jackets and structures. The loads are typically from current, waves and wind. This is combined with strain and motion sensors on various members. The system is based on both in-house and third party sensors, integrated into one system, on-line or battery driven. The sensors may be installed by diver or ROV, using clamps or magnets. The data is used to verify design, calibrate structure models and in connection with service life extension.

Our in-house capabilities with regards to structural analyses and lifetime extension provides a deeper foundation for understanding structural response, which allows us to optimise the monitoring system to provide required data for further analyses.


We use LVDT (linear variable differential transformer) and hydro acoustic sensors to measure displacement from a micro meter to meter range. This may be combined with other sensor systems to provide additional information. Systems are custom built to suit the application.

Vibration subsea and EEx Zone

FORCE Technology provides systems for monitoring high frequency vibrations (>1Hz), both subsea and topside, based on strain measurements and accelerations. Subsea monitoring may be combined with hydrophones, and is ROV/diver installable. Topside may include EEx Zone requirements.

Consultancy and expertise

The technology is sought after and in use worldwide, with large clients in the forefront of the oil and gas industry. This is partly due to the increased focus on health, safety and environment (HSE) in the offshore industry, which has lead to operators choosing a more pre-emptive approach. We specialise in technical integrity, and the ability to correctly evaluate and predict historical and future performance of offshore assets.
