Towards sustainable and circular maintenance strategies for (existing) civil construction objects: Developing a tool to stimulate the integration of sustainability and circularity via collaboration throughout the maintenance stage in the Dutch context

On a general level, the Dutch government wants to have a fully circular economy by 2050 by reducing the use of primary materials and carbon dioxide emissions. As the consideration and integration of concepts such as sustainability and circular economy are becoming increasingly popular in the civil engineering sector, it might be time to re...

Floating Offshore Wind Development Concept: A sustainable O&M approach

This research examines the difference between two major component replacement strategies for the novel floating offshore wind turbines (FOWT), in terms of support vessel CO2eq emission and cost together with FOWT downtime. The first strategy is utilising a crane vessel to replace a component in offshore, this is called the heavy lift maintenance...

The design of a sustainable and maintenance friendly wind turbine nacelle for DOT

Conventional offshore wind turbines tend to be difficult to maintain. Maintenance contributes to 25% of the total cost of energy and forms an important phase in the lifecycle of the turbine and has a significant impact on its sustainability. The design resulted from this master thesis is a nacelle for the DOT wind turbine. It creates a working...
