Questions and Answers

Match the following features of the Shoreham Offshore Wind Farm to their relevant information:

Operational lifespan = Initially projected to be 70 years, but now revised to potentially 10 years or less due to instability Efficiency = Considered one of the most efficient offshore wind farms ever built Cost of operation = Remarkably cheap compared to other offshore wind farms Stability = Compromised by inaccurate boundary layer equations, leading to scouring and swaying of turbines

Match the following factors impacting the Shoreham Offshore Wind Farm's lifespan to their descriptions:

Seabed stability = Compromised by inaccuracies in initial boundary layer equations, causing scouring and turbine swaying Projected lifespan = Revised downwards due to stability concerns, from 70 years to potentially 10 years or less Climate change = Potential to significantly affect the lifespan, with higher sea levels posing a threat Efficiency = Not directly related to the lifespan, but a notable positive aspect of the wind farm

Match the following terms related to the Shoreham Offshore Wind Farm to their definitions in the context of the passage:

Boundary layer equations = Mathematical calculations that were initially inaccurate, compromising the seabed stability Scouring = Erosion of the seabed, potentially caused by the inaccurate boundary layer equations Swaying = Unstable movement of the wind turbines, a consequence of the compromised seabed stability Lifespan = The expected duration of the wind farm's operation, currently estimated to be significantly shorter than initially planned

Match the following aspects of the Shoreham Offshore Wind Farm to their corresponding characteristics:

<p>Initial construction = Replaced an older wind farm at the same location, indicating a move towards more modern technology Age = Only been in operation for 5 years, relatively new compared to its projected lifespan Efficiency = High efficiency, making it a cost-effective energy source Stability = Experiencing instability issues due to inaccurate initial calculations, potentially impacting its longevity</p> Signup and view all the answers

Match the following issues affecting the Shoreham Offshore Wind Farm to their possible causes:

<p>Compromised seabed stability = Erroneous boundary layer equations Swaying of wind turbines = Scouring of the seabed due to stability issues Reduced lifespan = Compromised stability and potential impact of climate change High operating costs = Not mentioned in the passage, indicating the wind farm is relatively inexpensive to operate</p> Signup and view all the answers

Shoreham Offshore Wind Farm

A wind farm operational for 5 years, replacing an earlier one at Shoreham.

Boundary Layer Equations

Mathematical representations that describe fluid flow near boundaries; initially erroneous for this farm.

Seabed Stability

The firmness and integrity of the seabed where turbines are placed; compromised in this case.

Projected Lifespan

The expected operational duration of wind turbines; originally 70 years but reevaluated to 10.

Study Notes

Shoreham Offshore Wind Farm

  • The wind farm is only 5 years old, replacing a previous one at Shoreham.
  • Initial design calculations for the foundation boundary layer were inaccurate.
  • Seabed stability is compromised, causing scouring and turbine swaying.
  • While turbines are currently relatively stable, structural integrity for the projected 70-year lifespan is not guaranteed.
  • Revised lifespan estimates are now 10 years or less, depending on sea level and climate change.
  • Despite design flaws, the system boasts high efficiency and low operating costs.
