Together!​ Background of the graduation assignment It is expected that the market for the laying and burial of bundled submarine power cables will increase the future. Most projects comprise a bundle consisting of two power cables, with an additional fibre optic data cable. Some involve bundles of three power cables with an additional fibre optic data cable. While the installation of bundles consisting of two cables is common practice, modelling of a cable bundle is proven to be difficult. There is therefore a clear need to systematically identify existing knowledge gaps and to further advance the understanding of bundled cable installation. Research questions * What are the stress levels in bundled cables during laying and burial, particularly when the cable trajectories (catenary shapes) of the individual cables within the bundle differ? * How do these stress levels vary for: * Bundles consisting of two cables? * Bundles consisting of three cables? * What is the influence of the bundling stiffness and the applied bundling method on these stress levels? * How can bundled cables be accurately modelled (in OrcaFlex)? * How can the laying and burial process of bundled cables be effectively controlled to limit installation risks and cable stresses? * What are t
