Windthrust unveils floating offshore wind port concept
Windthrust Limited, the
Wind Energy Division (and a wholly owned subsidiary) of National Ports
Corporation Ltd., has developed a technology for offshore wind installation.
The Oceandock LX is a 60,000m² self-propelled floating port and installation
vessel for substations, monopile foundations and wind turbine generators.
The concept features a 60,000 square metre clear deck area, 700,000 cubic
metres of underdeck area and over 600 metres of docking space for the berthing
of multiple feeder ships delivering wind turbine components. The floating
port solution is designed to provide a stable and secure storage for over
500,000 tonnes of substations, monopile foundations and wind turbine generator
components. Furthermore, it can accommodate over 100 personnel and is not
required to return to port for reloading.
It is designed with three cranes which will cover every square metre of
the 60,000 square metre deck and can operate independently and simultaneously
with different tasks. With a 6,000-tonne crane, the concept can position
a 6,000-tonne substation topside in one single lift.
The Oceandock solution is designed offer a cost-effective alternative to
current systems such as jack-up vessels which are inadequate and far too
The Oceandock simultaneously unloads wind turbine components from feeder
ships, assembles and installs complete wind turbine generators, substations
and monopile foundations. Unlike conventional jack-ups, the Oceandock is
not required to return to the port for reloading.
The assembly of the wind turbine generators take place at near deck level;
making it possible for the complete wind turbine generator units to be
placed in position in one single lift.
