In case you missed out on this excellent event PES brings you your exclusive post show report from last month’s, 10th Offshore Energy Exhibition & Conference, which took place in Amsterdam, The Netherlands under the theme Transformation through collaboration. During the Offshore WIND Conference, part of Offshore Energy, as well as on a discussion square on the exhibition floor, there was attention for collaboration between the offshore oil and gas industry on the one hand and the offshore wind industry on the other and how this can transform energy transition on the North Sea. On the North Sea, energy transition is taking place under our eyes. On the hand we see strong growth in offshore wind and on the other hand we witness cessation and decommissioning of oil and gas production activities. At a place on the Offshore Energy exhibition floor called ‘Community Square’ – designed to cater to the entire offshore oil, gas and renewables community – there was a television style talk-show on the future of the North Sea, more specifically on the future of North Sea energy infrastructure. The talk-show was organized in cooperation with the ‘North Sea Energy program’ – a research program financed by the

With the interest in wind energy on the rise, foundation suppliers are hard pressed to meet the developers’ demands in terms of design, delivery and installation. PES brings you the PEIKKO view from the North, where investment in new turbines is paying off and energy from wind is ever increasing. Wind the most profitable way of producing energy Wind has always been clean, but now it’s also economical. According to the American Wind Energy Association, ‘wind prices are extremely competitive right now, offering lower costs than other possible resources’, while Bloomberg New Energy Finance has noted that ‘onshore wind is fully competitive against gas and coal’. This has created a wind energy boom with some 30,000 new turbines built every year to add to a tally of around 500,000 wind power plants in use around the world. A quantum leap of turbine technology The wind is in the middle of a similar technology leap that revolutionised the cell phone performance and use a decade ago. We have seen a significant increase in the turbine size and power generation figures. ‘If you take the situation three years ago as a baseline and give that an index of 100, we are now at 250,’ Kari Tuominen,

Gerry Lalonde, CEO, Orenda Energy Solutions, tells PES how he feels wind energy could be exchanged from one location to another. This is certainly food for thought and could make a big difference to small turbine owners, or perspective owners with no space near their current location. One of the chief concerns facing the small/medium wind energy industry is a geographical one, based purely on supply and demand. Imagine a business located in the middle of an urban area that wishes to be self-sustaining with its own ‘green’ electricity supply. If the business is located in an area where there is little or no wind and local planning laws preclude them from siting a small turbine on the property, is there not a conversation to be had with Government, which leads to a relaxing of the rules whereby any business can buy and erect a turbine on a ‘wind-friendly’ landscape, in another part of the country and have access to the equivalent amount of generated energy by these turbines from the grid? Is this not a classic case of supply not being efficiently matched to demand? Current legislation prohibits an energy consumer based on the South Coast of England, to purchase a wind turbine

Words: Steven Foong, Global Maritime This article will look at the marine operations standards and guidelines that are emerging; areas that need to be considered in putting in place such standards; and how it is also incumbent on the marine providers themselves to put the necessary mechanisms in place internally. There’s no doubt that offshore wind is on the increase in Europe, Asia and the United States. Bloomberg New Energy Finance, an energy research organization, predicts that the world’s offshore wind-generation capacity will quadruple by 2025. The size of wind turbines is also increasing at such a rate that turbines with a capacity of up to 15MW are likely to be installed in the near future, according to the Chief Executive of Renewable UK, the UK trade association. The European Wind Energy Association also estimates that between 20 GW and 40 GW of offshore wind energy capacity will be operating in the European Union by 2020. Yet, just as the industry is continuing to grow, so do the necessary marine standards need to improve to ensure safe and effective operations. Current standards & guidelines So what current marine operations standards and guidelines are being used? While such standards and guidelines in offshore wind were perhaps slow to take

Words: Scott Starr, Firetrace International, Marketing Director Wind turbine fire protection: investing to protect the bottom line. Fire is the second leading cause of accidents in wind turbines after blade failure1, with the average overall cost of a wind turbine fire being around $4.5m2. Given that $112.5bn was ploughed in to wind power globally in 20163, wouldn’t it be prudent to invest a little more of that in fire suppression? When a fire occurs the typical action is simply to wait for it to burn out. This can cause significant damage leading to thousands of dollars of repair costs, plus revenue losses as a result of downtime. To illustrate, a single 2.5-3MW commercial scale wind turbine is valued at approximately $3-$4m4, with the value of the output averaging $2,8005 per day. It’s clear, therefore, that the financial impact of even a minor fire, which can still cause weeks of downtime, can be significant - the average total cost of a wind turbine fire is $4.5m6. Causes There are generally three main causes of wind turbine fires: mechanical failure, electrical malfunction and lightning strikes. A small fire can accelerate quickly in a nacelle that comprises highly flammable resin fiberglass. Internal insulation in the nacelle, which

Does a bottlenose dolphin change its ranging movement because of a wind turbine? Or a razorbill change its migration route? How do human beings change behaviours with an offshore wind farm nearby? PES brings you a pioneering scientific research programme from Vattenfall, which aims to answer these questions and more. Four projects have initially been selected to receive a share of the €3mn Scientific Research and Monitoring Fund which is the brainchild of Swedish energy company Vattenfall. The projects will be based at Vattenfall’s European Offshore Wind Deployment Centre (EOWDC) in Aberdeen Bay. Adam Ezzamel, Project Director for the EOWDC, said they felt such a programme represented an opportunity that was too good to miss. ‘These projects will be carried out in a real-time environment as part of the largest-scale offshore wind programme of its kind. Conducting this research at the EOWDC is an unmissable chance to gain hitherto unknown knowledge of the environmental effects of offshore wind developments. ‘Not only will this programme place Scotland at the forefront of research and development in the sector and reinforce its position as a renewable energy powerhouse, it will inform industry policy-making in Europe and beyond.’ The 11-turbine EOWDC is Scotland’s largest offshore wind test and

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
