DEME Group’s GeoSea has concluded the trials of a jack-up vessel at Raz Blanchard, off France.
According to DEME, the demonstrated utilisation of GeoSea’s jack-up platform under the extreme tidal conditions are the direct result and the practical implementation of a two year in-house study analysing and researching the behaviour of jack-up platforms while jacked-up in strong currents.
On that basis, DEME states, specific operating models as well as procedural and technical improvements have been developed that enable the use of the GeoSea’s respective jack-up platforms and vessels in strong tidal race areas.
GeoSea’s jack-up vessel Goliath operated in currents of up to 10 knots (approximately 5 m/s) and water depths, under hull, of 56 meters.
“This is an important milestone in the tidal energy sector which will accelerate the construction of tidal turbines and all related operations such as maintenance and decommissioning. GeoSea’s practical experiences under those demonstrated extreme conditions should give confidence to developers and project owners alike to use cost effective jack-up platforms and vessels for the realization of their tidal projects,” DEME Group’s press release reads.
GeoSea offers various services to owners of offshore assets, marine consultants and marine contractors in the sectors of offshore oil and gas, renewable energy and civil engineering.
DEME is a Belgian dredging, marine engineering and environmental group.
