Objective
To enhance and integrate existing advanced techniques for survey data acquisition, pipeline behaviour simulation and fitness for purposes assessment of subsea pipeline systems, including marginal and deep water developments.
To demonstrate the application of these advanced techniques for route optimisation and IMR by means of an Offshore Field Test.
To have the route optimisation and IMR elements of the packaged tested by potential end users namely a pipelay contractor and pipeline operator.
To disseminate the results of the project to the oil and gas industry through the proposers global network of offices, leading to commercial exploitation of the technology. The demonstration of a pipeline simulation that includes a realistic contact model of seabed/pipeline interaction. The use of seabed discrimination survey techniques to determine the nature of the surface, and inclusion of this geotechnical data whithin the seabed model of the pipeline behaviour simulation.
The demonstration of problem solvers covering spanning, upheaval buckling, onbottom stability, mud-slides and trawl-board pullover for the purpose of route optimisation and fitness for purpose assessment.
SIMULATOR problem solvers covering on-bottom stability, spanning and upheaval buckling are available from JP Kenny.
The SIMULATOR project will provide an improved quality of engineered assessment of the behaviour and fitness for purpose of a pipeline system throughout the design, installation and operating phases of its life.
The project will have two modes of operation namely route optimisation and Inspection, Maintenance and Repair (IMR). In the route optimisation mode a wide variety of survey/soils information will be gathered including swathe bathymetry, seabed sediment data by acoustic discrimination methods, geological and geotechnical properties. This data will be processed to produce a digital terrain model (DTM) of the seabed. This can be used by engineers for seabed visualisation and preliminary pipeline routing. Candidate routes are then subject to a pipeline behaviour simulation using the FLEXCOM-3D finite element engine and the SEASCAPE problem solvers to determine the fitness for purpose of the route and the required amount of pre and post installation seabed works. The engineerscan then optimise the pipeline design and route in order to minimise the material and energy costs of the seabed works by repeated use of the pipeline behaviour simulation.
In the IMR mode, the data gathered during the annual inspection survey is imported into the as-built model of the pipeline held in the pipeline simulation. The FLEXCOM-3D finite element engine and SEASCAPE problem solvers are used by the engineers to determine the fitness for purpose of the pipeline. The need for remedial measures (if any) are determined and trend analysis of items such as anode consumption, self burial and lateral displacement is possible.
