It’s an exciting time at the Port of Rotterdam. It already has a flourishing business network and is set to get even bigger with the development of the Offshore Center Maasvlakte 2. Joost Eenhuizen, Business Manager, Port of Rotterdam Authority, provides PES with a look in to the future at this unique project in Europe. The ambition of the Port of Rotterdam Authority is to be a world leader in the field of sustainability. The goal is greener industry and logistics, which will improve and maintain the environmental quality. The use of alternative energy supplies such as wind, solar and biomass is increasing so as to provide a viable alternative to fossil fuels. It’s in the Port of Rotterdam’s (PoR) DNA to look ahead and plan new developments. Two new markets, offshore wind and decommissioning are now firmly in sight due to this new venture. The Oil & Gas industry will also benefit from the improvement and expansion of the already good port capabilities. The development of the ‘Offshore Center’ didn’t just happen. It has come after years of thorough research and hundreds of various discussions with different offshore companies, in order to ascertain the needs associated with such big expansion. This ensures

As of 2011 OWI-lab, in co-operation with the Vrije Universiteit, Brussels (VUB), has been conducting a long term structural monitoring campaign at all Belgian offshore wind farms. The measurements focus on the structural health of the substructure (SHM) rather than the wind turbine itself. PES is pleased to share this important research, which is sure to have an impact on future wind farm monitoring. This different focus was motivated by the operators of offshore wind farms. While the correct operation of the wind turbine is typically covered under a service level agreement with the turbine OEM, other vital components such as the substructure, foundation and cables along with the offshore high voltage station and grid infrastructure, fall under the responsibility of the operator. It was from their concerns that OWI-lab started to research and develop tailored monitoring solutions and search for decision support tools towards the substructure. Dealing with operators’ concerns One particular concern posed by the operators is the development of scour around the foundation. During scouring the seabed around the foundation is eroded, reducing the embedded length of the foundation. This has a direct effect on the structural properties. With the development of a scour hole, the exposed length increases and

Offshore Project Support (OPS) from the Netherlands combines the knowledge, experience and equipment of four different offshore companies. Together, they are ‘the toolbox at sea’. A complete service for every stage in wind energy projects. Niels Noordeloos is OPS’s managing director. ‘Titles don’t really mean much to me. I’m a practical kind of guy who just happens to know exactly what’s going on in the offshore industry. I enjoy managing projects and like to come up with safe and well considered solutions. With OPS I can offer my clients the services they need.’ Niels Noordeloos has worked in the offshore industry for 16 years and has been working as a freelance project manager over the last couple of years. ‘First in the gas and oil industry, later on in the offshore wind industry. At one point I was wondering if we could reduce costs by combining different projects. I envisioned a chain of wind parks from the southern part of the North Sea up to northern part of the North Sea. One vessel could sail to

As renewable energy adoption grows worldwide, major utilities increasingly rely on wind power to serve homes and businesses with emission-free, clean electricity. Because of this growing interest in cleaner energy sources, the wind industry is experiencing a period of significant growth worldwide, exceeding 500 gigawatts and employing more than 1.2 million people. This growth has increased focus on issues like the equipment’s sensitivity to extreme environmental factors, subsequent power interruptions and revenue loss, increased maintenance, and maintenance-related safety risks. To keep up with this growing demand, operators must continue to stay ahead of potential challenges. Like all power sources, wind turbines are vulnerable to harsh weather conditions and require fail-safe operating systems such as emergency pitch units, commonly referred to as EPUs, which help safely halt turbine operation. As a result, turbine operators and owners are increasingly depending on electrical-based pitch control systems to perform this function. Traditional EPU (emergency power unit) In periods of total power failure, the EPU is equipped with an emergency power supply to return the blades to a safe position and allow the turbine to shut down effectively. These systems have typically relied on batteries to perform this function. Because of batteries’ electrochemical nature, they are prone to

I know what you are thinking, right now you may be considering installing an offshore windfarm and here I am telling you about the problems of getting rid of the thing again. But! The topic is relevant whether you are installing a windfarm, nearing an end to the operational life, or actually in the process of preparing the decommissioning of the windfarm. Why, you might ask, is this relevant, the removal of the wind turbines is actually the reverse operation of installing it or not? The answer is that this is actually not the case. And as usual the devil is in the detail. Here are the reasons. In the early years I was frequently asked to give a quote for how much it would cost to remove an offshore turbine, my answer was simple, the same plus inflation as it would cost to install it. This is partly the answer, however a significant number of costs will occur which we did not foresee when we were originally asked. Firstly, the sheer number of turbines, which have to be removed, will make a significant impact to the port where you have to unload them. For the Danish and German North Sea, Esbjerg seems a good bet.

Ideol has been in the news these last few weeks because Floatgen, France’s first offshore wind turbine, has successfully reached two key milestones Bruno G. Geschier, Chief Sales and Marketing Officer, at Ideol, came in to PES to talk us through this ground breaking project. Beyond the completion of the floater construction and the September fitting of the transition piece and the wind turbine at quayside, there were two decisive and delicate operations scheduled this summer: the pre-lay of the mooring lines as well as the float-off, or separation, of the concrete structure from the floating barges on which it was built. With cost competitiveness being a key driver in this emblematic project, we set out to design an innovative mooring system using nylon ropes several years ago. This being a first-of-a-kind we also had to develop and optimize specific offshore installation methods to ensure smooth, safe and rapid offshore operations. Having a fully integrated team of engineers covering all phases of the project, from conception to completion, helped us to integrate such offshore installation constraints and specificities very early on in the design and engineering phase, limiting many unforeseen and often costly surprises down the line. It also helped us collaborate efficiently with

There are currently five consented offshore wind developments planned for off the North East coast of Scotland, so the region is trailblazing in terms of investment and tangible projects getting off the ground. Part of AREG’s strategy is to identify and drive forward projects that will bring economic development value to the region. We want Aberdeen to be as famous for renewables as it is for oil and gas. There needs to be a sustainable energy sector, which supports jobs for future generations and it is important we retain critical energy skills as well as promoting our capabilities across the country and globally. One of the key attractions of the North East of Scotland is our well-developed supply chain with globally recognised expertise in engineering solutions designed for harsh water conditions. What scale of wind farm is being planned? The wind farms are all very different in terms of concept and construction. At one end of the scale we have three innovation led projects, and at the other, two industrial scale power stations. The European Offshore Wind Deployment Centre (EOWDC), Scotland’s largest offshore wind test and demonstration facility is being developed by Vattenfall. Located in Aberdeen Bay, the 92.4 MW 11 turbine offshore wind

It is clear that the solar revolution is sweeping across the globe, with or without governmental incentives. Particularly in North America, the largest job creator in the past year has been singularly the solar industry. But a deeper analysis reveals that most of the growth over the past decade has been in utility-scale sector, although certain states like California, New Jersey, and Pennsylvania lead the way in residential sector as well. Even in these states, if we look a bit deeper into the residential sector, we find that most of the penetration has been in the mid to upper echelons of society, while leaving out the vast majority of low income communities. Thus, in a sense, solar is still the playground of the rich, in spite of drastically falling costs in the industry, and significant federal, and state level incentives. Consequently, the affordable housing residents do not have an opportunity to enjoy the savings due to solar installations, nor the health benefits of clean power. To make matters worse, most of the coal plants are located close to low income communities. We don’t need to look far to find out the reasons for this situation; the residents of low income communities cannot

Schneider Electric and AdSolar collaborated to build a unique solution giving energy independence and self-sustainability to a high end residential estate development in South Africa using a community level centralized storage with decentralized power generation. Background At a time of rolling black-outs on the South African electricity grid, AdSolar was tasked with designing a power solution for 11 new homes in a luxury estate development in the Upper Highway area of Durban’s western suburbs. The goal was to provide power generation, delivery and security without compromising the homeowners’ lifestyle. Given the complexity of the project, AdSolar selected a solution from Schneider Electric’s broad range of solar technologies to meet their client’s needs. The cost of grid power in South Africa is ever increasing to allow utilities to maintain and expand their distribution networks and generation capacity. This increase in power costs in South Africa combined with deteriorating grid stability is pushing more consumers to want to take control and go off-grid. Rolling black-outs leave homes in South Africa exposed to the risk of crime, food decaying in fridges and freezers or simply the inconvenience of power going off when you need it most (in the middle of preparing your meals, showers in the morning,
