Structures

LICengineering has carried out a variety of research and deveopment activities related to offshore and subsea structures. A selection of activities is listed below.

Driving of pipes                     Driving of large steel pipes with flanges to investigate the flange behavior when subjected to direct hammer loads. 

Flange connections              Detailed FEM and dynamic analysis for flange connections on large monopiles.

Upheaval buckling               Structural analysis of subsea pipelines including seabed subsidence effects.

Structural integrity              Supply of accelerometer and data acquisition package to North Sea oil and gas/wind operators for monitoring and theoretical management                       calibration of structural service lifetime. Furthermore, set-up of Digital Twin solutions.

Subsea pipeline                   Development of new structural analysis tools.                                                                                                                                                           tie-in spools

Subsea structures               LICengineering has developed a piled subsea protection structure, drilling templates, porpoise detectors, bucket foundation for float                                                out, tripod wave measurement stuctures and wellhead protection structure.

Wind foundation                 Various projects including EUDP projects.

ATP Wind structures          Development of a strap suspended airtight platform included in a flanged monopile for platform installed onshore prior to pile driving.                                               This is implemented on one of the first large offshore wind farms in UK waters.

ATP wind                              Development of a new patented AirTight Platform with Client for monopile/transition piece connections.

Monopiles                            Modal analyses.

Conductor design               Adapt LIC methods to the new AWARE hydrodynamic loads.

Conductor verification      Development of structural methods to include conductor casing connectors in the structural analysis.

Ships                                    Ship impact and push-over structural analysis.
