Within the Space@Sea project, FDS is working on a number of work packages using different numerical approaches for a variety of tasks.
Within the design work package, the institute contributes by conducting multi-body interaction simulations of several island modules in waves, assessing maximum expected forces and motions of the platforms. This knowledge directly feeds into the design process.
Within the work package devoted to installation and operation, the FDS group assesses limiting environmental conditions for the installation process. This serves to gain a high reliability estimate of workability and hence the cost to be expected due to weather down times. Additionally, resistance computations of the tow-out are conducted in order to estimate the tug capacity needed for such operations.
For design of the Energyhub@Sea, the institute contributes by conduction extreme sea state simulations of the wave energy converter ring which is placed around the island to harvest energy and reduce the impact of wave forces on the inner-island applications. The limiting state analysis is required for the dimensioning of the connections between WEC module and main island and for the layout of the power-take-off device.
The operability of an offshore container hub, as designed in work package 9 of the Space@Sea project, depends on the relative motion between berths and moored vessels. In collaboration with the TU Delft and mocean, a performance-enhancing control system was developed, with TUHH providing the information on initial relative motion of vessel and multi-body quay for irregular seas.
