Offshoretronic has developed a new game-changing ADD-ON Installation Support Tower Concept to be installed as an addition to our unique Dual Crane Offshore Wind Installation Vessel.
With this entirely new transportation and installation method, large cost savings can be provided by utilizing the same monohull crane vessel for the installation of all kinds of offshore Wind Foundations and for the transport and installation of Wind Turbines as one single unit.
This new concept allows Offshoretronic to transport and install two completely finished wind turbines of up to 11 MW capacity in one single round trip, which results in large cost savings of around 40% in operational time and around 15% in fuel consumption compared to large Jack-up vessels. For larger turbines, Offshoretronic can install the turbine tower together with the nacelle as one single unit, whilst the turbine blades could be installed with a smaller size Jack-up vessel in assistance mode. The ADD-ON Installation Support Tower is fully modular and can be installed and removed by the Vessels own Heavy Lift Mast Cranes.
To allow for smaller and lighter support tower construction, all weight of the turbine is supported on the Lower Support Beam and by the Crane Boom wires. This arrangement will give additional load stability and support to the Support Tower. The lifting and lowering of the wind turbine will be done by the mast crane main winches with a lifting and heave compensation capacity of 1200 MT.
The safety aspects of our new Concept Design has our highest priority. Therefore, the Turbine Tower will be resting and secured on a Support Beam during transportation and both top and bottom grippers will have two additional secondary retentions around the Turbine Tower. This will give extra support and allow for a very safe transportation and installation process of the turbine.
In the coming years Offshore Wind end-users are expected to go mainly for larger Wind turbines in the range of 12-15 MW, said Project Director Jeroen Berkhout ’’However industry researchers and analysts predict that over the next decade still smaller size turbines in the range of 9-11 MW turbines will be produced and installed, particularly in more remote areas for logistical reasons and areas that would face hurricane wind gusts and require smaller size reinforced, hurricane proof turbines. Hence we foresee still a good market for our new Concept particular in combination with our unique Dual Crane heavy lift installation vessel”
