Deep Foundations and Underground Infrastructure EuropeYunShi
The conference will showcase some of the most advanced and specialised foundation and geotechnical projects across Europe, such as the Anholt Windfarm and Cityringen in Denmark, the Olympic Thames Cable Car towers in London, the Hallandsås Tunnel and Slussen in Sweden, the Maasvlakte piers and Amsterdam Central Station floating foundations in Amsterdam and many, many more. In addition, the conference will keep you up to date with Eurocode 7 to learn about the forward plans and current challenges.

- Reasons for increasing crane structural failure
- Types of failure
- Finite Element Method (FEM) solutions
2015 Foundations for larger and deeper Offshore Wind MEC Intelligence
For offshore wind farms installations, foundation selection plays an important role in the overall concept design as there are large financial implications attached to the choices made. Foundation costs are primarily driven by material & installation costs and have been considered in this report.
New foundation designs have lower costs as turbines become larger and installed in deeper sea. For instance, 6 MW, new foundations are ~4-20% lower in material cost when compared to monopiles & jackets while for turbine sizes 8 MW and larger, new designs reduce the cost by ~21-24%. Cost reduction potential of 5-15% is observed for foundations at selected 5 farms in Europe. However, developers need to manage risk and other associated premium costs with appropriate contracting.
This reports presents detailed and fact based evaluation of foundations technologies for larger & deeper offshore wind farms. It also offers an evaluation of innovations that could assist in driving down the cost of the installation of foundation for offshore wind farm operations.

+ Use of longer stands in - Most frequently reason for
the derrick (3 instead of 1 NPT
joint)
+ Quickly engage the - Higher Dayrate
pumps or the rotary while - Derrick capacity reduced
tripping pipe
- Lack of experience of rig
+ Back reaming
crew
+ Washing and reaming
+ Decease possibility of - More wear on drilling line
“stuck pipe” (?)
+ Less joint connection has
to made
+ Well control improvement
