SATH technology contributes to the optimization of mooring systems for floating wind

MooringSense project is supported by the European Union's Horizon 2020 research and innovation programme and aims to develop a specific approach to design an efficient mooring system integrity management, including affordable strategies for OPEX reduction and reliable on-line monitoring technology, as these are critical components for floating wind energy due to their impact in the stability, structural design and dynamics of the platform.

For the next 36 months, 9 partners from Europe’s key OW industry and academia with remarkable international activity, will share their knowledge and experience in offshore wind industry to carry out the detailed work and resources plan set for this initiative: Fundación Centro Tecnológico de Componentes (CTC), Saitec Engineering, Zunibal, Nederlandse Organisatie Voor Toegepast Natuurwetenschappelijk Onderzoek, Vicinay Marine Innovación, Ikerlan, Sintef Ocean, Bridon Bekaert Ropes Group and Intecsea.

MooringSense will use Saitec Engineering’s SATH floating platform, an innovative semisubmersible concept, with a single-point mooring system and a pre-stressed-concrete floating platform that achieves reduced construction and maintenance costs. A reduced scale model will be used as a case study and will be tested to develop a numerical model of the mooring system and a realistic baseline assessment in terms of CAPEX, OPEX and LCOE. In order to do so, Saitec Engineering will provide mooring system optimal configurations that will be combined with other partners contributions to identify degradation mechanisms and failure modes.

The proposed solution to achieve these objectives will consist on the integration of several components/prototypes that will be validated in a relevant environment to measure and assess the achieved performances against the specified technical requirements.

In the end, the expected results could lead to an 15% OPEX reduction by means of an increase of Annual Energy Production by 2-3% and, indirectly, to CAPEX reduction by 4.5%.
