[en] The race to gain offshore wind energy a larger proportion of the energy market increases
the need to reduce operational costs. Such costs occur during maintenance where corrosion
is a factor.
Having to compete with the oil and gas industry. The offshore wind sector faces the
same challenge as any other offshore sector; corrosion. However, The term corrosion is
not limited to saltwater and humidity but also UV radiation. The purpose of an offshore
structure is to support the function of the equipment on board. Any excess weight of the
supporting structure is irrelevant as long as the integrity is ensured.
In addition, decreasing structural weight can lower the costs pertaining to transportation,
construction as well as O & M. Undoubtedly, the two main concerns are corrosion and
weight. By considering using alternative materials, both challenges are tackled. The use
of glass-reinforced polymer is already evident in oil and gas. Hence, to further reduce
the cost in the supply chain. Polymers are now considered. Currently, experiments for
polymers are being conducted in Cefan department of Navantia. The results are promising
with additive manufacturing.
Non-structural elements are not subjected to strict regulations. This increases design
flexibility that allows material properties to be fully utilised according to the design.
Offshore non-structural components such as handrails, grating, cable trays and HVAC
vents can all be made from composites. Yet, the main challenge of glass-reinforced plastic
is recycling. thermoplastic presents an alternative solution to the design for manufacturing
as well as an advantage in terms of sustainability.
