Germany’s Federal Maritime and Hydrographic Agency (BSH) has published a list of 31 offshore wind projects that fulfil the pre-requisites for participating in 3.1GW in interim offshore wind tenders in 2017 and 2018. Most of the 21 projects in the North Sea and 10 in the Baltic Sea have already been licensed, while for some of them at least a public hearing has been held before an August 1, 2016, deadline. “The objective [of the list] is to increase clarity as to whether the projects fulfil the pre-requisites,” the BSH said, but added that the list is merely informative and makes no statement yet as to whether the projects are qualified to take part in the tenders. Germany plans to carry out a first 1.55GW interim auction on March 1, 2017, and a second one of the same size a year later. The price for support will be capped at €120 per megawatt hour of electricity produced, and companies are required to hand in a guarantee of €100,000.00/MW of installed capacity when handing in the bid. The list of North Sea projects contains many established offshore operators, such as Dong Energy or EnBW, while the Baltic Sea list contains several projects by Iberdrola Renovables. Among the projects are the 252MW Deutsche Bucht project in the North Sea, for which project company British Wind Energy has lined up MHI Vestas as preferred turbine supplier, and E.ON’s 385MW Arkona Becken Südost project in the Baltic Sea. Link to the full list of projects. Updated with price caps for support under the tender

Sweden's Roxtec has been selected as a preferred safety seal supplier by contractor Engie Fabricom, following the deliveries for the substation at Dong Energy's 258MW Burbo Bank Extension offshore wind farm off the UK. The supplier's transits have been used on the platform to seal off hundreds of high voltage power cables, signal and fiber optic lines, and a wide range of pipe penetrations on everything from air-conditioning to fire-fighting systems. "The challenge is to keep out the sea atmosphere," says Engie Fabricom's Willy Martens. Roxtech's Multidiameter concept, which uses removable rubber layers and allows for a "perfect seal regardless of the outside dimension of the cable or pipe", is designed to speed up installation and reduces the need for stock, material and logistics. The BBE substation, built by Engie Fabricom at its Hoboken yard in Belgium, will collect power from 32 MHI Vestas 8MW V164 turbines for transmission to shore from the development in the Irish Sea. Submarine power cable technology specialist JDR has landed the contract to supply inter-array lines to SSE's 588MW Beatrice offshore wind farm off Scotland. As part of the order with development contractor Siem Offshore, JDR will manufacture 180km of cables to connect up the 84 turbines at the project site, 18km offshore in the Outer Moray Firth. "As the only UK manufacturer of inter-array cable, our technology offers a reliable, high quality solution to the Beatrice project," says JDR chief executive David Currie. JDR will manufacture the cables at its facility in Hartlepool, UK, with delivery scheduled for Q2 2018. Switch-on of the Beatrice wind farm is slated for 2019.The cable-maker also supplied the inter-array cables for SSE's pioneering Beatrice demonstrator project 10 years ago. Danish wind OEM Vestas had a good week in Asia with a 100MW win in China and 50MW in Mongolia, its first deal in the latter. The Chinese order came from long-term customer CGN for 50 V100 machines for a wind farm in northeastern China. Vestas will supply 25 V110 turbines to Mongolia's second wind project, which is being co-developed by Japan's SB Energy in the Gobi desert. The power sector has become a prime target for a massive increase in the number of successful cyber-attacks over the past year, due to the increasing interconnection of the industry and emergence of smart grids, warns a new World Energy Council (WEC) report.The report says in the worst case these attacks can result in infrastructure shutdowns, affecting renewable energy facilities, and triggering economic and financial disruptions, or even loss of life and massive environmental damage. The report, entitled 'The road to resilience: managing cyber risks', investigates how cyber risks can be managed, taking into account the changing nature of the energy industry due to the rapid growth of renewables and expanding energy infrastructure. “The energy sector must take a systematic approach and assess cyber risks across the entire energy supply chain,  improve the protection of energy systems and limit any possible domino effects that might be caused by failure in one element of the value chain,” says Jeroen van der Veer, executive chair of the study and a former CEO of Shell. Senvion has signed a contract with Elicio NV to supply 21 MM100 2MW wind turbines for the Alibunar project 60km north of Belgrade in Serbia, the vendor’s first sales in the Balkan nation. Earlier, Senvion closed another conditional deal with the developer covering four MM100s for the Malibunar project. Both transactions include 15-year service agreements. Senvion officials say the deals are evidence that its strategy for entering new markets is showing results. Vestas has won a “firm and unconditional” order for 13 V126-3.45 MW turbines from project developer Green Wind Energy and the operator of the turbines being repowered, European Energy. The deal includes a 20-year full-scope service agreement and VestasOnline Business SCADA solution. The turbines will be installed at the Prignitz wind park in Brandenburg, eastern Germany.  Wind turbine delivery and commissioning is planned to begin in the first quarter of 2017. Developer Acciona Energía has inked a deal with US industrial software firm Sentient Science to roll out its DigitalClone technology for the pilot phase of a project aiming to pare down its 7GW fleet's levelised cost of energy (LCoE).The Sentient Science system, which creates digital clones of each turbine model to predict risk of component failure based on operational data, will be used in full turbine monitoring, testing, life prediction and life extension actions. "This represents a big step forward in our 'turbine for life' programme to obtain the maximum performance from our turbines and be ever more competitive," says Acciona Energía chief executive Rafael Mateo. The deal envisages "a long-term collaboration" covering more than 6,000 wind turbines spread across more than 200 wind farms in 14 countries. DNV GL awarded German utility Innogy the project certificate for its Nordsee Ost offshore wind farm at the WindEnergy Hamburg event. The 295MW wind farm in the German North Sea is one of the country’s first offshore projects to be awarded a full certificate, said DNV GL. The certification was carried out according to the standards of the German Federal Maritime and Hydrographic Agency (BSH). Siemens has tied up a five-year service and maintenance agreement for the turbine substructures and substation at the 400MW Veja Mate wind farm under construction in the German North Sea. The deal kicks in from mid-2017 and adds to the German group's existing service deal to look after the 67 6MW turbines it is supplying to Veja Mate, under development by a consortium led by Highland Group. Ralf Christian, CEO of the Siemens Energy Management Division, said: “We are able to service a multitude of different systems offshore and obtain the skills to reliably and sustainably provide full maintenance of electrical, mechanical and structural components, including planning and logistics as well as fault clearance for complex projects – built by Siemens or other market players.” MHI Vestas confirmed an earlier conditional order to supply Vattenfall's 92MW European Offshore Wind Deployment Centre (EOWDC) with its V164MW machine – and said the plant will be the first to use a powered-up 8.4MW version that will be the world's most powerful wind turbine. The EOWDC is best known as the project unsuccessfully fought through the courts by would-be US President Donald Trump, who claimed it would ruin the views from his nearby golf course. German wind OEM Nordex has linked with aviation group Lufthansa to advance the use of drones for turbine inspection. Nordex will partner with Lufthansa Aerial Services (LAS) to carry out inspection flights, with a particular focus on blades. The OEM said: “By collecting a large amount of data the manufacturer can monitor the ageing of the turbines and find out for each specific type at which intervals a rotor blade has to be inspected or serviced with a view to preventive maintenance.” Technology and innovation consultancy Totaro & Associates has launched a new intelligence tool designed to help OEMs and their suppliers predict future wind industry product requirements. Totaro & Associates claimed MKT Prism has an edge as it “accurately predicts future market share by taking into account the wind resource which has not already been built out, an improvement upon conventional market evaluation tools which look only at supply and demand factors that fluctuate wildly and have been proven to be historically inaccurate”. A major OEM has already ordered the system, it added.

Revenues at Germany-based wind turbine manufacturer Senvion in the third quarter 2016 suffered from a decrease in onshore turbine sales in its home market, but earnings were impacted by write-downs related to the OEM’s recent IPO. Revenue fell to €584.3m ($631.4m) in the third quarter from €608m a year earlier as a decrease in German onshore revenues was only partially compensated by higher sales in the UK, France, Portugal and offshore. Revenue from the sale of offshore wind turbines soared to €88.3m in the third quarter from €26.7m, driven by project progress on the 332MW Nordsee One and the 111MW Nordergründe projects. Senvion stressed that revenues actually went up 15.6% compared to the previous quarter, and pointed to a turnaround in order intake. Senvion’s intake of firm turbine orders with €292m in the third quarter of 2016 was lower than the €327m in orders a year earlier, but orders were improving from earlier quarters this year. Order intake had bottomed at €269m in the first quarter, and reached €284m in the second. Firm orders in the third quarter included an 112MW onshore wind order from Norway, while the OEM also gained 305MW in conditional orders, among them a 203MW order for the Trianel Borkum II project in the German North Sea. Trianel Borkum II has been listed by the German Federal Maritime and Hydrographic Agency (BSH) as one of 31 projects that fulfil the pre-requisites for participating in 3.1GW in interim offshore wind tenders in 2017 and 2018 for already licensed projects. Overall firm orders for turbines stood at €1.5bn at the end of the third quarter, with another €1.9bn in conditional orders, and €2.2bn in service orders. Senvion also confirmed a 300MW preferred supplier agreement from Australia. Developer Nexif Energy had said yesterday it plans to use Senvion’s recently launched 3.6M140 onshore power horse for two of its wind projects in Australia. "On the back of our continual rollout of innovative and energy cost efficient products, we continue to make progress on our global growth strategy successfully,” Senvion chief executive Jürgen Geissinger said. “We will continue to develop tailored products for all wind categories to be available for the specific requirements in our growth markets, which will be the base for our future profitable growth." Earnings before interest, taxes, depreciation and amortisation (Ebitda) rose to €58.5m in the period from €27.4m in the third quarter 2015 that was heavily impacted by purchase price allocation (PPA) results, Senvion said in its earnings report. The PPA’s derive from the acquisition of Senvion GmbH by Senvion SA in April 2015 in the run-up to Senvion’s IPO in March 2016 when its owners, the investment funds Centerbridge and Arpwood, sold a minority stake in Senvion. Therefore, only a limited comparison can be made between 2016 and 2015 financial figures, the company stressed. When adjusted for the PPA effects, Ebitda reached €60m in the third quarter of 2016, down from €68.1m a year earlier, due to lower revenue and higher personnel costs. Senvion posted a net loss of €0.8m in the third quarter, an improvement from the €39.6m in the year-earlier quarter due to a lower impact of PPA’s in the third quarter of 2016.

The number of reported Vibrio-related wound infections associated with recreational bathing in Northern Europe has increased within the last decades. In order to study the health risk from potentially pathogenic Vibrio spp. in the central Wadden Sea, the seasonal and spatial distribution of Vibrio vulnificus, Vibrio parahaemolyticus, Vibrio alginolyticus and Vibrio cholerae were investigated at ten recreational beaches in this area over a 2-year period. V. alginolyticus and V. parahaemolyticus were found to be omnipresent all year round in the study area, while V. vulnificus occurrence was restricted to summer months in the estuaries of the rivers Ems and Weser. Multiple linear regression models revealed that water temperature is the most important determinant of Vibrio spp. occurrence in the area. Differentiated regression models showed a species-specific response to water temperature and revealed a particularly strong effect of even minor temperature increases on the probability of detecting V. vulnificus in summer. In sediments, Vibrio spp. concentrations were up to three orders of magnitude higher than in water. Also, V. alginolyticus and V. parahaemolyticus were found to be less susceptible towards winter temperatures in the benthic environment than in the water, indicating an important role of sediments for Vibrio ecology. While only a very small percentage of tested V. parahaemolyticus proved to be potentially pathogenic, the presence of V. vulnificus during the summer months should be regarded with care. © 2013 Springer Science+Business Media New York.

Purpose: Due to their high water solubilities and mobilities, persistent, polar perfluorinated compounds (PFCs) such as perfluorinated carboxylates and sulfonates are likely to end up in the oceans. In part 1 of this study, their distribution in North and Baltic Sea water is reported, being of special interest because these seas are surrounded by highly industrialized countries with high population densities. Methods: A combination of solid-phase extraction and liquid chromatography coupled with tandem mass spectrometry was used after optimisation to determine nine PFCs with chain lengths of C4 to C10 in water samples at ultra-trace levels. Results: The observed concentration distribution and gradients were explained by oceanographic mixing processes and currents. The big rivers were identified as major input sources. At the mouth of the river Elbe, concentrations of 9 ng/L were observed for perfluorooctanoate (PFOA), and 8 ng/L for perfluorooctylsulfonate (PFOS); all other PFC concentrations ranged from 0.6 to 1.7 ng/L. At coastal stations, concentrations decreased to 3.8 ng/L (PFOA) and 1.8 ng/L (PFOS), dropping to 0.13 and 0.09 ng/L, respectively, towards the open sea. Along the Dutch coast, high perfluorobutylsulfonate concentrations (3.9 ng/L) were observed as regional characteristics. In the Baltic Sea, fairly even PFC distributions with low gradients were observed. Again, PFOA and PFOS were the major compounds (up to 1.1 and 0.9 ng/L). Conclusion: The results underline the necessity to include PFCs in marine monitoring programs. Water was found to be a good matrix for monitoring environmental levels, sources, and transport pathways of PFCs. © 2011 Springer-Verlag.

Ice flow from the ice sheets to the ocean contains the maximum potential contributing to future eustatic sea-level rise. In Antarctica most mass fluxes occur via the extended ice-shelf regions covering more than half the Antarctic coastline. The most extended ice shelves are the Filchner-Ronne and Ross Ice Shelves, which contribute ≈30% to the total mass loss caused by basal melting. Basal melt rates here show small to moderate average amplitudes of <0.5ma-1. By comparison, the smaller but most vulnerable ice shelves in the Amundsen and Bellinghausen Seas show much higher melt rates (up to 30ma-1), but overall basal mass loss is comparably small due to the small size of the ice shelves. The pivotal question for both characteristic ice-shelf regions, however, is the impact of ocean melting, and, coevally, change in ice-shelf thickness, on the flow dynamics of the hinterland ice masses. In theory, iceshelf back-pressure acts to stabilize the ice sheet, and thus the ice volume stored above sea level.We use the three-dimensional (3-D) thermomechanical ice-flow model RIMBAY to investigate the ice flow in a regularly shaped model domain, including ice-sheet, ice-shelf and open-ocean regions. By using melting scenarios for perturbation studies, we find a hysteresis-like behaviour. The experiments show that the system regains its initial state when perturbations are switched off. Average basal melt rates of up to 2ma-1 as well as spatially variable melting calculated by our 3-D ocean model ROMBAX act as basal boundary conditions in time-dependent model studies. Changes in ice volume and grounding-line position are monitored after 1000 years of modelling and reveal mass losses of up to 40 Gt a-1. © 2012 Publishing Technology.

Eleven particle-size-segregated samples were taken to investigate the particle-size distribution of perfluoroalkyl substances (PFASs) using two five stage impactors in parallel. Samples were extracted with methanol and detected by HPLC/MS-MS. Investigation yielded reproducible results for the parallel samples over the entire sampling period. Particle-size distribution varied between perfluorooctane sulfonate (PFOS) and other perfluoroalkyl sulfonates (PFSAs), perfluorooctane carboxylate (PFOA) and other perfluoroalkyl carboxylates (PFCAs) and n-methyl-perfluorooctanesulfonamido ethanol (MeFOSE). Whereas PFOA and MeFOSE were predominantly observed in smallest size fraction (<0.14. μm), maximum PFOS mass fractions were observed in the coarser size fractions between 1.38 and 3.81. μm. The reason for this different behaviour remained unclear and indicated a complex atmospheric PFAS processing and sampling which should be further investigated and optimized, respectively. © 2014 Elsevier Ltd.

In this paper we present the first 236U-measurements from North Sea water samples. The measurements are performed within an ongoing project that intends to map the distribution of 236U in the Atlantic Ocean and thus to explore the potential of 236U as a new oceanic tracer. We describe the latest modifications of the low energy ETH AMS system TANDY that allow determining the concentrations of both 238U and 236U and the 236U/238U ratio during only one AMS measurement. Further, we present our chemical preparation procedure and, finally, the first 236U data from the North Sea is discussed in detail. A simple conceptual model is used to simulate the temporal evolution of the 236U-concentration in the North Sea. The simulated water mass residence time is in good agreement with independent oceanographic data. Based on these initial results we conclude that anthropogenic 236U has a large potential as a new transient and extremely conservative tracer in Oceanography. © 2012 Elsevier B.V.

Purpose: The distribution of polar perfluorinated compounds (PFCs) in sea water of the North and Baltic Seas has been described in part 1 of this study. In part 2, their occurrence in sediments is described in order to further investigate their distribution routes and possible sinks. Methods: Sediments were extracted with methanol and PFCs with chain lengths of C4 to C10 analysed by liquid chromatography coupled with tandem mass spectrometry. Results: Using the developed procedure, PFCs could be determined in sediments from all 15 stations which had been sampled. In most samples from the German Bight and western Baltic Sea, perfluorooctane sulphonate had the highest concentrations (0. 02 to 2. 4 μg/kg dry weight), followed by perfluorooctanoate at 0. 06 to 1. 6 μg/kg dry weight. Levels of the other PFCs were five to ten times lower. Concentrations of PFCs were similar to those of classical chlorinated hydrocarbons. The spatial distribution is strongly influenced by sediment parameters (e. g. total organic carbon (TOC)). By normalisation to TOC, regional differences were identified between the North and Baltic Sea samples. Sediment/water enrichment ratios estimated from field concentrations showed clear dependences on carbon chain length and chemical structure. Time trends of PFCs, investigated by analysing a sediment core (Skagerrak), differed clearly from those of "classical" pollutants. Conclusion: Because of the strong influence of sediment parameters and the relatively low enrichment of PFCs in sediments, this matrix is less suited for investigating spatial distributions. Sediments should be used mainly for monitoring temporal trends, preferably using sediment cores. © 2011 Springer-Verlag.
