Global Dynamic Analysis was used to carry out the dynamic tow analysis and the floating simulation (for installation).
We lead the project from the very first contact with the client to the presentation of results, ensuring the approach was well understood and accepted by all stakeholders. Leveraging our cross-capability expertise, we proposed the application of a combined CFD and Global Dynamic Analysis to provide the most accurate representation. Our client had limited experience in this area and therefore needed a level of guidance on the approach to the problem to ensure the most representative analysis. The analysis was necessary to output tow forces for a range of tow speeds and environmental conditions, loads/moments acting on the flanged connections between pipe strings and the forces, at regular intervals along the pipeline, required to hold it on-station while floating near shore in preparation for installation. With this project being a first of a kind, our client needed an accurate way to effectively de-risk the project and gain insight into the loading on the pipeline and its behaviour during transportation and installation. The outfall was transported from the North coast of Northern Ireland across the Irish Sea to Blackpool in the North West of England. We provided analysis of the installation process and the transportation of the 3.7km long Polyethylene outfall, the largest ever installed in the UK. We were selected by our client, a global multi-disciplined engineering and construction company to support them in the £20 million Anchorsholme project. This allowed for the most appropriate towing vessel to be selected and ultimately a successful installation.
