Graduation Assignment: Bundled cables

Working at Boskalis is about creating new horizons and sustainable solutions. In a world where population growth, an increase of global trade, demand for (new) energy and climate change are driving forces, we challenge you to make your mark in finding innovative and relevant solutions for complex infrastructural and marine projects

Are you ready to make your mark within Boskalis? During this internship you will work for the offshore energy division as well as the R&D department.

Within a vibrant company culture, you will be working as part of a diverse, international team of experts. We offer you the opportunity to realize your full personal potential and expand your professional career by creating new horizons. 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 the implications of bundled cable installation for the design of vessel deck equipment, such as chutes and tensioners?
• What are the consequences of bundled cable installation for burial tool design?

Research Focus

The primary focus of this graduation research is on a) the physics involved in bundling cables and b) the modelling of bundled cables, with specific emphasis on:

• Identifying and quantifying stress levels during different installation phases (laying and burial);
• Assessing how these stress levels depend on cable properties, bundle configuration, and bundling method;
• Systematically mapping installation risks related to cable stresses and translating them into design and operational recommendations.
