Each tie member will be lifted offshore together with the concrete foundation for quick installation and correct positioning of the foundation on the seabed. The pre-fabricated deck will be welded to the top of the pile...

... these will be exploited for the smart operation and maintenance planning of the floating foundations are discussed. The combined approach, novel for floating wind technology, is based on the use of modern component monitoring and control instrumentation, both installed on the floating platform and on the wind turbine...

... Semi-submersible type floating foundations often consist of 3 to 4 columns connected by pontoons/braces and are stabilized through a separated water plane area distanced from the platform center. Additional buoyancy can be provided by the pontoons; with the foundation moored by mooring lines...

... Offshore wind turbines do not have the same limiting factors with regards to blade transport and foundation size that onshore wind turbines do, and the result is ever larger, and therefore more cost efficient, turbines. The largest now is the Siemens-Gamesa 14MW prototype but designs up to 25MW...

... restrictors impose a limit of upward and downward movements for the Christmas tree, and as a consequence, for the wellhead. For rigid flowlines, these restrictions are even harder. Abstract As a general practice in the oil and gas industry, the well foundation, composed by the conductor and the surface...
