Offshore Wind Energy 2017

Layout optimization

WindEurope and RenewableUK have joined forces to host the world’s largest offshore wind conference and exhibition. It is expected to attract more than 10,000 professionals and showcase over 500 exhibitors from all sectors of the offshore wind industry. This international event will provide a comprehensive view of the trends, technologies and issues facing the offshore wind sector now and in the future.

Proud to support
DNV GL is proud to be exhibiting at Offshore Wind Energy 2017. We will be located on stands N-F60.

Presenting expertise
We are committed to leading or supporting a wide range of industry initiatives designed to reduce risk and prevent mistakes. We have also helped develop tools, guidelines and standards that enable the offshore wind industry to deliver optimized projects, as well as Joint Industry Projects (JIPs) to develop industry best practices.

Experts from DNV GL will showcase a range of offshore wind expertise during the conference.

Oral presentations

Panel presenter:Kim Mørk, Executive Vice President, Renewables Certification, DNV GL
Date/time:Tuesday 6 June, 14:30-15:45
Session:Technology developments - scaling up and bringing costs down
Location:Room 8


Session Chair:Ervin Bossanyi, Senior Principal Researcher, Strategic Research & innovation - Renewables, DNV GL
Date/time:Wednesday 7 June 2017, 11:30-12:45 
Session:Advancing technology by better design and validation
Location:Room 8-9


Presenter:Marie-Anne Cowan, Senior Engineer, Project Development, DNV GL 
Presentation:A review of wind speed inter-annual variability for the UK offshore wind climate 
Date/time: Wednesday 7 June, 14:15–15:30
Session:Modeling offshore wind 
Location:Room 8
Abstract:Historical studies of wind speed inter-annual variability (IAV) have primarily focused on measurements from onshore meteorological stations. From such studies, an “industry standard” estimate of wind speed IAV of 6% has been widely adopted across many global markets. Whilst refinements to this estimate have taken place in certain regions, a value of 6% continues to be largely considered standard in the UK offshore wind industry. This value is incorporated into pre-construction energy assessments to define historical and future uncertainties, and can therefore, have an impact on project financing arrangements and the Levelised Cost of Energy (LCoE) of offshore wind. It is therefore important to understand the representativeness of the IAV assumption of 6% in the UK offshore environment.


Presenter: Taylor Geer, Service Line Leader – Project Development, DNV GL 
Presentation:Getting it right: improving confidence in wake predictions through operational validations.
Date/time:Tuesday 6 June 2017, 16:30-17:45
Session:Offshore wind wakes: using operational data to improve models and reduce uncertainty
Location:Room 8
Abstract:The goal of this presentation is to provide the industry with both a method to verify the accuracy of wake models as well as initial results from applying this method to a number of widely available wake models. Improved confidence in modelling the wake effect at an offshore project provides substantial value for project planning, project financing, and project operations. The accuracy of a wake model can only be truly demonstrated through a robust validation using operational data. DNV GL will present both a comprehensive method for validating wake models as well results from applying this method to a number of industry standard, and emerging, wake models including the Eddy Viscosity wake model implemented in the WindFarmer software. In addition to looking at the accuracy of annual wake loss predictions, DNV GL will investigate the accuracy of wake models in a number of different environmental conditions to understand the sensitivity of the wake model accuracy in all conditions.


Session Chair:Tim Camp, Business Development Manager, DNV GL 
Date/time:Thursday 8 June 2017, 11:30-12:45
Session:Design and analysis of floating wind turbines 
Location:Room 8


Presenter:Kimon Argyriadis, Innovation Manager, DNV GL 
Presentation:Revision of DNV GL design standard for floating wind turbine structures
Date/time:Thursday 8 June 2017, 11:30-12:45 
Session:Design and analysis of floating wind turbines 
Location:Room 8
Abstract:TBC


Posters presentations

Presenter:Marie-Anne Cowan, Senior Engineer, Project Development, DNV GL 
Presentation:Asymmetric uncertainties in turbine availability of offshore wind projects: comparison with real operational wind farm data
Date/time:Wednesday 7 June 2017, 15:30–16:15
Session:Poster session 
Location:Poster area at the conference venue 
Abstract:A critical aspect of the energy production assessment of offshore wind farms is the definition of the technical energy losses and their associated uncertainties. Defining the uncertainty in the energy yield estimate is crucial to understanding the level of risk in a project and feeds into the economic analysis of a prospective project.


Presenter:Andreas Manjock, Principle Engineer and Offshore Project Manager 
Presentation:Comparison of 10MW Turbine Dynamics Between Bottom Fixed And Floating Foundations 
Date/time:Wednesday 7 June 2017, 15:30–16:15
Session: Poster session 
Location:Poster area at the conference venue
Abstract:TBC


Presenter: Simon Cox, Head of Section Offshore Projects
Presentation: Offshore wind cost of energy: what are the implications of very large turbines?
Date/time: Wednesday 7 June 2017, 15:30–16:15
Location:Poster area at the conference venue
Abstract:

Offshore wind cost of energy has reduced rapidly in recent years; one of the major contributors to this progression has been the development and deployment of ever-larger turbines. Understanding whether further increases in turbine size will offer additional improvement in cost of energy enables developers to better plan and design projects.

Further advances in turbine size will also bring logistical challenges, as the supply chain develops its capabilities to support practical deployment. Increases in turbine size will have impacts on support structures and installation assets, the development of which requires significant lead times.

This work investigates the potential cost of energy reduction provided by very large turbines, and the logistical implications of deploying such large turbines at scale offshore. The results of the study show that very large turbines offer a notable reduction in the cost of energy, and that investment by the supply chain in fabrication facilities and installation vessels will be required.
