There is an abundance of energy resources in the challenging offshore environment: oil, gas, minerals and renewable energy such as offshore wind, wave and tidal energy. Offshore structures and line connections need to be installed to harvest and transport that energy. Deltares supports offshore contractors, energy utilities and engineering companies during the design, installation, operation & maintenance (O&M) and decommissioning phases. Our specific expertise of waves, currents, geotechnics, geology and morphology, including their complex interactions, is of key importance for offshore projects. We develop knowledge and tools for the industry that guarantee safe, reliable, sustainable and cost-efficient operations.
The main topics we cover in the field of offshore engineering are:
- Metocean conditions, both for normal and extreme conditions (waves, water levels, currents, wind etc.) Raw metocean data can be obtained via www.metoceanatlas.nl
- Seabed morphodynamics and the prediction of seabed changes during the lifetime of an offshore project
- Hydrodynamic loads such as currents and (breaking) waves
- Local scour and scour protection around offshore infrastructure
- Geotechnical design of foundations
- Pile installation techniques (hammering, vibrating, drilling etc.)
- Cable and pipeline routing, burial depth assessments, protection methods and risk assessments

Hydrodynamic loads from waves, currents and ice are always very site-specific. Wide variations in soil conditions mean that the optimum foundation option for each site is always different. It is not possible to simply copy a single solution : each offshore project requires a tailored approach. We combine a scientific approach based on the latest knowledge with practical experience to develop solutions that work.
Special approach: Hybrid modelling
At Deltares, we have a wide range of tools: from scale models to numerical models and from field measurements to data-driven analysis methods. In order to determine the optimal solution for the client, we combine the strengths of each tool. This is referred to as “hybrid modelling”.
