The effect of ocean waves on offshore wind turbines
The Ocean has a varying surface roughness where the roughness length is determined by the characteristics of the waves. In this paper, a method is established where the roughness length of the ocean is calculated from the wind speed and the fetch length. The fetch length depends on the wind direction and a case study is performed for a wind turbine exposed to wind blowing in two opposite ...

Maintenance Manager to control operation and maintenance of offshore wind farms
Maintenance of wind farms is of increasing importance. Especially in remote areas, where logistics and accessibility are restricted, costs of preventive as well as corrective maintenance form a substantial part of the costs of electricity. The importance of a tool that assists in feedback to the design, failure logging, configuration control and maintenance planning is evident. This paper ...

Tidal influence on offshore wind fields and resource predictions
The rise and fall of the sea surface due to tides effectively moves an offshore wind turbine hub through the wind shear profile. This effect is quantified using measured data from three offshore UK sites. Statistical evidence of the influence of tide on mean wind speed and turbulence is presented. The implications of this effect for predicting offshore wind resource are outlined.Keywords: Tidal, ...

Prospect of offshore wind energy development in Japan
In Japan, the cumulative capacity of wind turbine generation systems on land has increased steadily in recent years. To install a large number of wind turbines has inherent problems such as shortage of suitable land, and inadequate infrastructure such as power cables and roads. The necessity for development of offshore wind turbine generation systems has been recognised based on the above ...

Life cycle assessment of a 150 MW offshore wind turbine farm at Nysted/Roedsand, Denmark
The purpose of this life cycle assessment (LCA) was to illuminate and describe the potential environmental impacts caused by an offshore wind turbine farm (WTF) throughout its lifetime and use this knowledge in the planning and improvement of future WTFs. The LCA was based on experience from the LCA on Danish electricity and district heating [1] as well as the offshore WTF project at ...

TOWERPOWER - Case Study
Objective: TOWERPOWER was focused on the development of a real-time remote monitoring system to diagnose the aging of the metal structure of offshore turbines. The ultimate goal was to reduce maintenance costs in offshore wind energy. The project included the design of a sensor system based on acoustic emissions (AE) and guided waves capable of monitoring the vibrations and degradation of the ...

Record 13bn euro invested in offshore wind in 2015: 3GW new capacity
Offshore wind investments in Europe doubled in 2015 to €13.3 billion in a record year for financing and grid-connected installations. A total of 3,019 MW in new offshore wind capacity came online in European waters in 2015, more than double what was connected to the grid in 2014. Europe's total offshore wind capacity is now 11,027 MW. A further 3,034 MW of capacity - spread across ten ...

Research and development in ocean energy technologies
The volatile fuel prices for electricity generation, elevated concerns about global warming and energy security has prompted countries to look for alternative energy sources. One of the alternative energy sources is ocean energy. Currently, there is few ocean energy technologies that are commercially available to harness electrical energy from ocean despite the fact that ocean covers more than ...

Winds of Change: Offshore Wind Farms at the Forefront of Energy Transition
At a time when the importance of turning to sustainable energy sources and reducing our carbon footprint is increasingly recognised, offshore wind farms represent a ray of hope amid growing concerns about the energy crisis. They constitute a significant step forward in the search for long-term solutions in the field of renewable energies and sustainable development. In this article, we take a ...

Rising offshore plant capacities lead to greater data-based O&M gains
The growing size of offshore wind farms provides greater scope for data optimisation during Operations and Maintenance, while software solutions can also help mitigate risk during the development phase, Marcus Ihle, Senior Consultant at Outsmart, said. Further gains could be made if operators share more data from their growing databases with other plant owners, Ihle said. The Levelized Cost of ...

Floating wind digital twin set to accelerate wave impact learnings
A new digital twin project led by floating wind developer Principle Power will use advanced wave behavior analysis to improve load calculations critical to long-term design efficiency, project partners told New Energy Update. Last month, U.S. group Principle Power announced it would lead a consortium of public and private groups to develop the world's first digital twin software for floating ...

What’s the Future of R&D in the Wind Industry?
When the wind industry finally reacted to the world’s financial crisis—it didn’t fully hit us until 2010—at once, we lost both an incredibly vibrant global wind market and sufficiently robust profit margins. The market recovery is rebounding nicely now, thanks largely to government incentives, but profit margins will probably never fully recover—at least, not to the ...

Multi-megawatt wind turbines for offshore use: aspects of Life Cycle Assessment
Life Cycle Assessment (LCA) is an instrument to quantify environmental impacts of the entire energy supply chain. According to the LCA, an appropriate indicator system should comprise all steps of a system's life cycle: production, operational and disposal processes ("cradle-to-grave"). Cumulative Energy Demand (CED) might be seen as one part of LCA as far as the depletion of energy resources in ...

Look what’s cooking in the world of renewable energy
The solar and wind innovations that got us where we are today — and those waiting in the wings — point to a hopeful future. Inside a sprawling single-story office building in Bedford, Mass., in a secret room known as the Growth Hall, the future of solar power is cooking at more than 2,500 °F. Behind closed doors and downturned blinds, custom-built ovens with ambitious names like ...

Monopiles to remain Dominant Offshore Foundation in Europe: Consultant
Monopiles will be Europe’s dominant offshore wind foundation for the next five years despite increasing turbine capacity, Tim Fischer, Head of Wind at German consultancy Ramboll, said. Monopile projects have dominated the offshore wind market but windfarms are moving towards larger turbines requiring larger foundations. While many proponents are promoting the value of jacket foundations ...

Offshore wind installation vessel capacity to tighten after 2020
The existing fleet of turbine and foundation installation vessels is well suited to serve the European offshore wind market in the short and mid-term but it will not be sufficient to support installation demand after 2020, Michael Guldbrandtsen, senior consultant at MAKE Consulting, told Wind Energy Update. The next 2-3 years will continue to be dominated by orders for jack-up installation ...
