ECA Fitness for service

A subsea pipeline was plastically deformed due to accidents. The outcome was the validation of the engineering ciritcal assessment (ECA) with maximum defect size.

Comparing wear resistance using roughness measurements

Using different in-house tools, initial friction tests were carried out on the coated metal components. 3D-roughness measurements were used to compare wear performance.

Stability of jack-up barge

The question was raised under which condition of weather and leg height, resonance of a jack-up barge could occur. A safe operational window to avoid lock-in of the legs was identified and critical conditions have been determined.

Stability of subsea pipeline

The stability of subsea pipelines, marine risers and offshore structures can be compromised by fluid-structure interaction. Vortex induced vibrations lead to fatigue of flow lines under free span and risers. It was possible to determine the loading pattern and compare it to the pipeline’s characteristics.

Fatigue of wind turbine hub

Fatigue analysis of a mid-size wind turbine hub at various load conditions was requested. Furthermore, a comparison between welded and cast hubs was needed. The computation demonstrated that it was possible to use a welded hub

Cost-reducing solution for offshore jacket foundations

Cost reduction is an important topic in the offshore wind sector. However, in view of the move to larger turbine sizes and deeper waters, costs of foundation structures will rise. It is now possible to test tubular joints having the dimensions of offshore wind turbine jacket structures at millions of cycles within a week and with low energy consumption.

Offshore pipe reeling modelling and testing

Reeled pipelines are submitted to cyclic deformation during reeling and unreeling operations. The behaviour of the plastic deformed pipe needed assessment. The ultra-low cycle fatigue characteristics of the pipe were determined as well as the feasibility of the pipe to multiple bending cycles.
