Structures and Integrity

De-risking critical aspects for concept selection and enable cost-effective design and fabrication of support structures through reduced uncertainty and application of novel methods.

Work Package 1 is lead by Vigdis Olden from SINTEF Industry and Ana Page from NGI. Its focus areas are environmental loads, limetime and performance, design and fabrication.

Anticipated results:

  • Improved methods for prediction of interactions between environmental loads, soil and structure.
  • Decision support platform for lifetime prediction
  • Cost-effective serial production of substructures


Fundamental understanding and accurate models of load, response, and degradation will be a key enabler for design, digitalised operation and lifetime prediction of support structures.

Methodology and research tasks

Environmental loads and response modelling

Hydrodynamic load models, site investigation methodologies and soil structure interaction and integrity.

Integrated design assessment and optimization

Multi-scale aero-hydro-servo-elastic modelling and reliability-based structural design optimisation.

Lifetime, performance, and integrity

Precision in degradation models. This is linked to Work Package 4.


Cost-effective mass production by automation and optimised and light-weight design and materials for secondary structures. Linked to Work Package 2 and 3.

Ambition for innovations

Improved models

Improved models for reliable predictions and better
understanding of interactions between environmental loads, soil, and structure. Accurate knowledge of site conditions and extreme environmental loads is insufficiently applied in early-phase design.

Decision support platform

Decision support platform for life prediction based on advanced model and condition monitoring. Limited understanding and modelling capabilities for material damage during operation.

Cost-effective production

Cost-effective serial production of offshore sub-structures, including a high degree of automation. Manual welding and coating are bottlenecks and cost drivers in fabrication.
