Renewable power is one of the main drives to achieve carbon reduction and net-zero, and to meet the ambitious climate goals. In particular, offshore wind power in Europe has been developing at a rapid pace in recent years. Multi-Giga watts offshore wind farms with larger wind turbine power ratings, floating wind turbines installed in deeper water areas, and higher ratio of renewables integrated to existing power grids, are fundamentally changing power system operations and bringing new challenges and technical demands. This industry-doctorate consortium, ADOreD, will recruit and train 15 Researchers by collaborating with 19 academic and industrial organisations. It aims to tackle the academic and technical challenges in the areas of transmission of offshore wind power to the AC grid by using power electronics-based AC/DC technologies. In doing so, it will equip the Researchers, through their PhD studies, with essential knowledge and skills to face fast energy transition in their future careers. The project covers 3 key research aspects: offshore wind (including wind turbines, wind power collection, and wind farm design and control); DC technologies (including AC/DC converters, HVDC control and DC network operation and protection); and AC grid (including stability and control of AC grids dominated with converters under various control modes. The ADOreD consortium has excellent coverage of academic universities and industry organisations including manufacturers, energy utilities, system operators, consultancy and technology innovation centres. All the research questions in the project reflect industry needs; academic novelty and innovation will be reflected in the methodologies and solutions; and the research results will be disseminated directly to the industry partners' products, grid operation and services. The outcomes of the project are both technologies and a talent pool to accelerate the deployment and grid integration of large-scale offshore wind power.

The ModConFlex consortium comprises a group of 10 academics and 4 senior researchers in industry (ORE Catapult) with expertise in control theory, artificial intelligence, complex dynamical systems, distributed parameter systems, fluid dynamics, aeroelasticity, power electronics, power systems, swimming theory and marine engineering. Our aim is to train the next generation of researchers on the modelling and control of flexible structures interacting with fluids (water and air), contributing to the latest advances in control theory, artificial intelligence and energy-based modelling. Our main applications are in the control of floating wind turbines (the prime renewable energy source of the future), and in the control of highly flexible aircraft, aircraft with very high aspect ratio. Our research plans are organized into three scientific work packages, which cover mathematical systems theory (modelling and model reduction, boundary control systems, port-Hamiltonian systems, exact beam theory), relevant aspects of control theory (internal model controllers with anti-windup, nonlinear model predictive control, robust control), reinforcement learning, aeroelasticity, stochastic algorithms. We believe that science and technology in Europe will greatly benefit from this research, and from the education and knowledge that we will impart to a new generation of researchers. Key strengths of this consortium include a research environment that brings together mathematicians and engineers to provide the project's young researchers with a unique training environment, and a network of associated industrial partners that will allow all the young researchers to participate in industrial secondments. We have the critical mass to cover all aspects of training, and we have an excellent track record of past collaboration and of training young researchers.

This prosperity partnership project, UNITE, brings Fugro Ltd, a major Tier 1 offshore service provider, together with a world-leading robotics research team from Heriot-Watt University and Imperial College London to address key open research challenges for safe and robust robotic solutions in the offshore renewable sector. It specifically focuses on the development and deployment of perception-enabled, risk-aware underwater intervention techniques, which are critical for the widespread adoption of robotics solutions in this rapidly expanding sector. The vision of the UNITE project is to develop a holistic solution to autonomous and semi-autonomous underwater intervention applied to the maintenance and repair of offshore wind farms, remotely monitored from shore and safely operated worldwide. UNITE's research vision and programme aim at reducing the use of crewed support vessels for operation, keeping offshore turbines more productive with less downtime and more timely and cost-effective maintenance and repair. This will also support the industry to cut costs and carbon footprint while dramatically improving health&safety. In a world where climate change is increasingly impacting our lives, we need to accelerate the energy transition towards net-zero. The UK has a huge potential for Offshore Wind Energy and the UK government has made this a priority, planning to reach 1TW by 2050. To reach such ambitious targets, you have to imagine 10's of thousands of offshore wind turbines, deployed in some of the harshest environments on earth and able to reliably produce energy for decades. At present, the cost of operation and maintenance of such wind farms is 30% of the overall cost and is performed using manned vessels deployed in extreme environments, hence reducing the operational window they can be deployed, increasing the carbon footprint of operations and risk to the personnel deployed offshore. This will simply not scale when more and more wind farms are built and the availability, environmental impact and cost of the current solutions will no longer make sense. What is required is to replace these large assets by smaller, more environmentally friendly and cost effective robotic solutions, controlled safely from shore by a new generation of pilots, engineers and operators. This is already a reality, at least in advanced demonstrator form, when we are only interested in inspection. Remote drones, surface vessels and underwater systems can be sent to inspect subsea cables, turbines and other subsea assets. In some cases, they can be permanently deployed for long periods of time. However, when more complex tasks requiring intervention (contact and manipulation) are required, the current technology is not ready, especially in cases where the communication link between the robot and shore is intermittent, slow or unreliable. If not solved, this will dramatically impact the adoption of robotics (as existing solutions will still need to be deployed), and potentially stop it in its track, in turn reducing the progress of offshore renewable energy as a viable clean energy source. New research is needed to endow the remote robotic platforms with the intervention capabilities they require, as well as ensuring that the platforms are safe even when not in direct control of a human. For this to happen, robots (and their sensors) must be able to build an accurate map of the world around them and use this map to navigate around obstacles and towards targets of interest. They need to be able to interact with the structures safely (controlling force of interaction) and grasp objects whilst being subject to potentially significant external disturbances (currents, waves, etc) and coordinate their respective actions (e.g surface vehicle deploying an underwater system). They also need to understand when they might fail and alert an operator on shore to ask for support. This is what the UNITE proposal will tackle.

The UK presently has the largest installed capacity of offshore wind, accounting for 36% of global capacity in 2017. The offshore wind industry contributed 9.8% of the UK's power in the 3rd quarter of 2019. In the 2019 Offshore Wind Sector Deal, the sector committed to building up to 30 GW of offshore wind by 2030, with an ambition of increasing exports fivefold to £2.6bn. The Committee on Climate Change has recommended an installed capacity of 75 GW by 2050. Nearly all offshore wind turbines installed to date have been mounted on fixed bottom support structures located in water depths up to 60 m. Given the limited availability of suitable sites at such water depths, Floating Offshore Wind Turbines (FOWT) will become increasingly important over the next decade to achieve the Offshore Wind Sector Deal goals and to help achieve the UK target of net zero greenhouse gas emissions by 2050. The Sector Deal highlights the need for government to develop frameworks to support the advancement of technologies such as FOWT. Physical modelling is a critical tool for the development of a floating offshore wind turbine and is recommended in most development guidelines. This is especially true at early stages of the development of new concept with a technology readiness level (TRL) between 1 and 3. Testing model devices at scale in the controlled environment of a laboratory has many advantages. These include the proof (or otherwise) of novel design concepts, the ability to test in systematically changing conditions and the ability to test in conditions which have low occurrence probabilities (i.e. extreme events). Quantitative measurements of motions and loads on scaled FOWT models can be made with much greater ease and accuracy then at full scale at sea. Qualitative observations are far easier to observe as well. If done correctly these measurements and observations can lead to the evolution of device designs and concepts and reduce the chance of costly failure; if and when devices are eventually deployed at sea. The University of Plymouth COAST laboratory (www.plymouth.ac.uk/coast-laboratory) is a state-of-the-art research facility for the study of wave and current interaction with offshore and coastal structures using scaled physical modelling. It houses the Ocean Basin, a 35 m x 15.5 m tank with a raisable floor that can enable testing at water depths between 0.5 and 3 m. This project will establish the UKFOWTT - UK Floating Offshore Wind Turbine Test facility within the Ocean Basin. In addition to the wave and current generation that COAST can presently deliver, UKFOWTT will add wind generation to COAST. This will consist of a bank of axial fans, mounted on a gantry spanning the tank width and have the ability to generate winds up to 10 m/s, model gusting and have a controllable wind profile. The generator will be moveable vertically from just at the water's surface to approximately 1 m above. It will be rotatable +/- 30 degrees relative to the basin, enabling the influence of wave/current/wind/model alignment to be investigated. The primary purpose of UKFOWTT is to enable both fundamental and applied research in topics related to Floating Offshore Wind. This will be a unique facility within the UK, enabling systematic physical modelling experiments with wind, wave and currents simultaneously. Data collected from physical modelling can improve understanding of the underlying physics, support development of analytical theories and validate advanced numerical models. It is also a low risk method of testing new and novel concepts. UKFOWTT provides the associated instrumentation to support these studies. UKFOWTT will also support research in other sectors of Ocean and Coastal Engineering disciplines, including the Oil and Gas sector, floating wave, tidal and solar energy, autonomous vessels, launch and recovery operations and coastal defenses.

This project proposes a paradigm shift in the operational management and use of power converters that entails active reliability management. This involves predicting failure and managing the remaining useable life of the power converter. Power electronic converters are indispensable to modern civilisation. They are responsible for electrical power conversion for a range of applications that span the few watts for portable hand-held electronics to several gigawatts for entire electrical power networks. Over the past few decades, the need for industrial decarbonisation has intensified the research into more efficient and reliable power electronic devices, components and converters. This is because power electronic converters are required for integrating renewable energy sources (solar, wind, tidal etc.) into the electrical system. Furthermore, electric transportation, which is seen as critical for reducing green-house emissions, relies very heavily on power electronics. Hybrid and full electric vehicles require power converters to control the traction machine, likewise, electric trains require power converters. Marine propulsion has also adopted the electric paradigm with the gas driven turbine replaced by a converter driven electrical motor. However, as power converters are driven at increasingly higher power densities, several reliability concerns have been recognised. The power converters are comprised of power modules, which in turn are comprised of switching power semiconductor devices in an electrically isolating but thermally conducting package. The reliability of the power semiconductor device and its mechanical interconnects has been intensely investigated by industrial and academic researchers over the last decade. Silicon devices have been the principal technology in power electronics for the last few decades however, silicon carbide and gallium nitride devices have emerged as viable alternatives. These new devices are referred to as wide bandgap devices because they have energy bandgaps larger than that of silicon. The simply means that they can withstand more energy thereby increasing the efficiency of power conversion. The reliability of these WBG semiconductors is increasingly becoming a very important topic since these new devices are gaining increasing market penetration. In applications with high failure costs, for example, automotive traction, aerospace and grid connected converters, the uptake of new technology is slow. By developing technologies that can improve the reliability of these new devices and monitor their health on-line, the uptake of new WBG power modules is very significantly de-risked. This project aims to do just this, by providing a condition monitoring and health management platform for WBG based power electronic modules.
