Getting An Offshore Wind Farm Grid Compliant
With the ever-increasing goal off lowering the LCoE the effectiveness of the installation and commissioning process is essential. A key consideration, during this phase, is the approach to Grid Compliance. Whether it be the reduction of generation, interruption of WTG reliability tests or even delays to subsidy payments the understanding and inclusion of grid compliance factors is one that needs promotion and escalation on any Offshore Wind Farm. This presentation will share the experiences from Dudgeon OWF so that others may learn about the process, become aware of the interdependencies and ultimately avoid the pitfalls for future projects.

Beginning his Renewables career with Centrica Renewables back in 2010 Ajai was able finally able to fulfil a long-term aspiration of working in Offshore Wind as an Electrical Engineer. Following a few years at ScottishPower Renewables Offshore Wind, he took an opportunity with Statoil to work on Dudgeon and was seconded to Construction as Lead Commissioning Engineer for the Onshore Substation. Since the completion of the Substation Ajai has returned to Operations as a Senior Electrical Engineer and has more recently taken on the role of Acting Systems & Integrity Manager for Dudgeon and Hywind Scotland Offshore Wind Farms.

Wind Farm Layout Optimisation Using a 3D RANS Wake Model
Performing layout optimisations is important to reduce levelised cost of energy (LCoE) for offshore wind farms. Due to performance constraints, current layout optimisation processes use single axisymmetric turbine wake models with explicit analytical superposition. Previous studies show that these methods deliver inaccurate power capture in even simple multiple wake cases. This talk covers the validation of a new 3D RANS wind farm wake model which models multiple wakes, yet without requiring a prohibitive calculation time for layout optimisation. Case studies are presented of layout optimisation using this 3D wake model and compared with layout optimisation using single turbine wake models.


Philip Bradstock is a scientific software developer at ProPlanEn Ltd, chiefly responsible for the development of simulation code in WakeBlaster. He graduated with a Masters in Physics from Oxford University and then spent six years developing the wind turbine aero-elastic tool Bladed before joining ProPlanEn in 2017.

University of Strathclyde

Dynamic Wind Power Plant Control for System Integration
This project presents a holistic wind farm control approach that enables wind power plants to provide the full range of ancillary services including synthetic inertia at system-wide level rather than single turbine level. In order to detect a power system event and select the magnitude of the service provision from the wind farm, a fully instrumented small/medium generator is used. By slaving the wind farm output to the generator natural response during power system events, the wind farm is able to provide a stable scaled-up range of ancillary services without relying in delayed or noisy grid frequency measurements.

David Campos-Gaona received the B.E. degree in electronic engineering, and the M.Sc. and PhD. degrees in electrical engineering, all from Instituto Tecnolgico de Morelia, Mexico, in 2004, 2007, and 2012, respectively.From 2014 to 2016, he was a Postdoctoral Research Fellow with the Department of Electrical and Computer Engineering, University of British Columbia, Canada. Since August 2016, he is a Research Associate with the University of Strathclyde, UK.

Extreme Wave Loads on Large Diameter Monopiles: Are We Approaching the "Ringing" Sweet Spot?
Extreme wave loads on large diameter monopile foundations may be substantially increased by dynamic excitation of the structure due to complex loading mechanisms such as “ringing”. Conventional design methods do not capture ringing response, which has generally been acceptable as smaller diameter foundations have not fallen within the loading regime where ringing plays a significant role. However, with the trend towards larger turbines and larger diameter monopiles to support them, experience from the oil & gas sector indicates that this will not remain the case. This study explains how ringing may impact foundation design for Round 4 sites.

Steven is a hydrodynamics specialist, with over a decade’s experience working in a range of sectors, including offshore energy, commercial buildings, water infrastructure and nuclear. His work in the offshore energy sector has primarily focused on assessment of extreme environmental loads, where he has recently completed the in place wave load assessment for the detailed design of a 210,000 tonne concrete gravity substructure, and scour, where he has acted as a technical advisor on a number of UK windfarms experiencing issues with secondary scour due to complex near field flow effects around cable crossing structures and substation foundations.

Cable System Engineering Cost Reductions for Deepwater Floating Offshore Wind
The advent of large floating wind farms introduces the opportunity for serial production of standardised components in order to achieve significant cost reductions. In deep water (>60m), such cost reductions can be achieved through the optimisation of the array cable configuration. Isolating vertical motions of the floating wind turbine unit from the touch down point minimises fatigue and over bending. This reduces the likelihood of failures occurring. Parametric global analysis is performed to assess the fatigue and strength limits of an array cable with and without the use of a subsea arch in varying water depths and environments.

Gilles has over 15 years’ design, analysis and integrity management experience of flexible product systems including cross section design, in-situ analysis, manufacturing, fatigue assessments, inspection and integrity management. Gilles has a BEng in Mechanical Engineering (Design and Manufacturing), is a Chartered Engineer and member of the Institution of Mechanical Engineers.

Improved Characterisation of Offshore Wind Data
Extreme and Normal Offshore Wind (ENOW) is a new Joint Industry Project (JIP) to improve the characterisation of offshore winds. Standard formulations still in use to quantify winds for design, resource and operability assessments are based on limited datasets. Using met mast datasets collected over the past decade, this project is developing more appropriate formulations, with a focus on wind turbulence intensity, wind profile and gust factors. New methods will also be developed for derivation of long term statistics from widely available wind models. Data availability, and the drive to lower the cost of offshore wind energy, makes this work particularly timely and will reduce the uncertainty in the quantification of offshore winds.

Dr Laure Grignon is a Chartered Marine Scientist and Metocean and Renewables Consultant. Her main area of expertise is the provision of Metocean data and management of the Metocean elements of offshore renewables projects. She has worked on numerous offshore wind projects as a technical analyst and package manager while at RES, and now as an independent consultant. She has been involved in all stages of offshore wind farm delivery, developing innovative methods to drive cost reduction.

Safety and Productivity of Offshore Wind Technicians in Transit (SPOWTT): A Collaborative Research Project to Support Decision Making
Unscheduled operations and maintenance activities on offshore wind installations accounts for almost a quarter of the lifetime cost of an offshore farm. A proportion of that is time wasted in failed crew transits or workers unable to carry out their duties as a direct result of rough weather conditions. By better understanding the relationship between sea state, vessel motion, and technician health, wellbeing, and safety, it is possible to plan transits and work packages more efficiently and safely. The evidence collected through the current project will provide the basis for a decision support tool for marine coordinators and operations managers.

Jon Huddlestone is a Research Assistant and PhD student at the University of Hull. His background is in Psychology and academic interests are Human Factors and risks in Health and Safety. He is particularly focused on research in Offshore Wind, and works as part of Aura, multi-disciplinary Offshore Wind research group based at the University of Hull.  Aura’s mission is to deliver low-carbon innovation through collaboration to deliver world-leading multidisciplinary research.

GuD Geotechnik und Dynamik Consult GmbH

Experiences and Lessons Learned with New Design Approaches for Cost-Optimised Large Diameter Monopile Foundations
The economical design of offshore monopiles depends on the realistic modelling of the lateral embedment provided by the surrounding soil. The p-y curves for small pile diameters published in the API guidelines are commonly used for this task. For large diameter piles, Kirsch et al. propose a reduction of the effective friction angle depending on the pile diameter. Furthermore, Kallehave et al. and Kirsch et al. propose a modification of the API p-y curves to account for the higher soil stiffness at very small strains. The results of numerical studies and in-situ measurements support the validity of the proposed modifications.

Fabian Kirsch is a civil engineer and holds a PhD degree in geotechnical engineering from TU Braunschweig. He has strong expertise in foundation engineering and offshore geotechnics. He was involved in numerous offshore wind projects in the German North and Baltic Sea either as geotechnical expert, foundation designer or checking engineer on behalf of the certifying authority.

Reliable and Efficient Design of Driven Piles for Offshore Wind Jacket Structures
Wind turbine foundations, which represent around 25% of the overall turbine cost and include significant installation risks, have significant potential for cost reduction. To date, most foundations have been monopiles in relatively shallow waters; however, alternative solutions are required to tackle increasing water depths and turbine sizes. This paper focuses on the use of steel jacket structures founded on driven piles used to support wind turbine generators. Specific aspects of pile design considered include: CPT-based pile design methods, assessing the impact of cyclic loading and the effect of soil structure interaction on natural frequency and load distribution in the structure.

Robert is a Senior Geotechnical Engineer in Atkins’ Offshore Geotechnics team and is based in Glasgow.  He is a Chartered Civil Engineer and for the last six years has worked on the design of foundations for a range of offshore wind projects in European waters.  Key projects include the Dudgeon, Beatrice and Triton Knoll offshore wind farms, for which he has undertaken both geotechnical design and engineering management roles.

ORJIP Phase 2: Improvements to Standard Mitigation Measure During Piling: Understanding the Effectiveness of ADDs on Minke Whale
A priority consenting risk for offshore wind is the potential effects of subsea noise (primarily during pile-driving) on marine mammals. To address this risk, ORJIP proposed a project to investigate the efficacy of Acoustic Deterrent Devices (ADDs) to deter marine mammals during piling. RPS led Phase 2 of this study and carried out in-field testing on the efficacy of ADDs to deter minke whale and to provide recommendations on use during construction. The study was conducted in Faxaflói Bay (Iceland) and demonstrated that ADDs are effective at invoking a deterrence response without the risk of inducing injurious effects.

Enabling Technology: Innovative Cable Lay
Cable lay operations in offshore wind are approaching two hurdles – how to efficiently overboard multiple buoyancy modules onto floating windfarms without cable kinking, and how to overboard deepwater cable whilst maintaining structural integrity. Failures on existing OWFs are becoming unsustainable, and the paper addresses how these risks are mitigated. 2017 saw patents granted for overboarding concepts that will enable standard CLVs achieve all functions whilst maintaining cable integrity. In both cases, a moving continuous belt imparting no friction or point loading to the cable, is installed over the existing stern chute. The paper will highlight these concepts as vessel enablers.

Mr Rippe is Business Director with MAATS Tech, a leading specialist in cable handling systems in the offshore wind industry, with significant supply scope on NKT Victoria, Lewek Connector, and DEME Living Stone.

Performance and Validation Assemessment the High Definition Modular Multilevel Converter for Offshore Wind Turbines
This work presents the results of an experimental assessment of a novel High Definition Modular Multilevel Converter (HD-MMC) algorithm. The HD-MMC algorithm increases the number of voltage levels created by a given MMC topology without additional hardware, particularly useful in low and medium voltage applications. Results from an experimental validation and assessment of the HD-MMC algorithm compared to a conventional MMC using Nearest Level and Pulse Width Modulation (NLM and PWM) are presented. These show that the HD-MMC achieves a similar reduction in Total Harmonic Distortion (THD) compared to using PWM while greatly reducing the number of switching events.

Predicting Failure of Dynamic Cables for Floating Offshore Wind
Technological advancements in the offshore wind industry have increased the viability of large floating turbines. All floating structures will require cables to run through the water column, from their base at the water surface to the seabed. This exposes the cables to the dynamic forces produced by marine currents, waves and motions of the floating platform. Therefore, predicting how these cables will perform and survive offshore is crucial. This presentation will discuss the forces a dynamic cable will be exposed to. How these forces contribute to the mechanical stresses across a cable cross-section is also analysed and presented accordingly.

David Young is a research engineer at the Industrial Doctorate Centre of Offshore Renewable Energy, IDCORE. He is completing his doctorate thesis on predicting dynamic subsea cables failures in conjunction with IDCORE and the Offshore Renewable Energy Catapult.

Wind Turbine Performance Assessment and Power Curve Outlier Rejection Using Copula Modelling
The conventional means of assessing performance of a wind turbine is through consideration of its power curve. However, this representation fails to capture plausibility of measurement and cannot provide anomaly detection capabilities, which may assist in the detection of plant degradation. Although the probabilistic form of the power curve is complex, Copula models are presented here as a means of expressing the operational power curve as a joint distribution of wind speed and power output. This probabilistic model is demonstrated as an efficient way to remove outliers from operational SCADA data, simplifying and accelerating the process of identifying plant maloperation.

Giorgio Zorzi is a PhD Researcher at the Doctoral Training Centre in Wind and Marine Energy at the University of Strathclyde, Glasgow. His main area of research is control of wind turbines and in particular the study on new way to improve their yield. He received his MSc and BEng in Electrical Engineering from the University of Padua, Italy. Prior to joining academia, Giorgio worked as a teacher of technical subject in a high school in Verona, Italy. His current project is on wind turbine performance assessment and power curve outlier rejection using copula modelling.
