B4 - Multi-purpose hybrid systems for ORE and ocean resources
B - Fluid-structure Seabed Interaction
Under-utilisation of the available ORE and ocean resources, and high cost of trialling new applications in isolation.
Hybrid systems exploiting more than one ORE or ocean resource, raising utilisation of ocean infrastructure including floating platforms and export cables.
Context And Need
For all offshore renewable energy technologies there are significant costs and design challenges that are associated with the site location and metocean conditions rather than directly with power generation. This includes power export from an offshore location; access to offshore infrastructure with acceptably low risk and provision of a floating or fixed supporting structure. Co-location of devices for generating power from more multiple ORE resources on the same sub-structures, or at the same site, offers the potential for improved economics of power generation from a given site
Challenges to such integration include:
- Combining ORE technologies that are at differing stages of development and for which power generation per device may differ by factors of four or more.
- Combining ORE technologies with other ocean resources, such as desalination, aquaculture, energy storage, engineering habitat
- Design methods for infrastructure accounting for the multiple loading types and dynamic response modes occurring due to multiple ORE device types.
Multi-use platforms may be platforms supporting both wave and offshore wind, offshore wind and tidal stream devices or integration of wave energy devices within sea walls and defences. Also includes the sharing of sea space and infrastructure with oil and gas structures or aquaculture.
Potential for significant reduction of overall CAPEX (per unit of energy).
Potential for increased environmental acceptance by limiting sites exploited.
Potential for some reduction of operating risk and OPEX.
