Vattenfall Ready for German Offshore Wind Tender with 3 Projects

Vattenfall is expected to participate in the first competitive offshore wind tender in Germany with three projects. 

The company today welcomed the launch of German tender for 1.55GW of offshore wind capacity, saying three of its projects meet the criteria to take part in the auction currently underway.

These include the Atlantis I and Global Tech II projects, which Vattenfall acquired in January of this year and in the summer of 2016, respectively. The third project is Nördlicher Grund Teil Sandbank, part of a larger Sandbank offshore wind plan that includes 64 additional turbines of which 24 have been approved.

The deadline for submission of bids is 3 April and the upper limit for the compensation of offshore wind power is set at 12 Eurocents per kilowatt hour.

Gunnar Groebler, Vattenfall’s Head of Business Area Wind, said that the results achieved in Denmark and the Netherlands through competitive tenders carried out last year show a clear trend of falling offshore wind costs. He pointed out that Vattenfall had set a new benchmark for cost-efficiency with the price of 4.99 Eurocents per kilowatt hour for the Danish Krieger Flak project.

“Although the costs for offshore wind projects cannot be transferred with a 1: 1 ratio due to the different framework conditions for offshore wind projects in Germany, there is much evidence that the basic trend will also be introduced here,” Groebler said.

Aarsleff Nets Nissum Bredning Deal

Aarsleff has been awarded a contract for the 28MW Nissum Bredning project in Denmark, where Siemens will test a variety of its new offshore wind solutions.

The Danish contractor will build concrete transition pieces and install the new gravity jacket foundations at the site off Rønland in Denmark, a spokesperson from Siemens confirmed to Offshore WIND today.

At the beginning of this month, Spanish joint venture Navantia-Windar informed it will supply the three-legged jacket foundations and accompanying piles for the project.

Siemens is using piles at the Nissum Bredning offshore wind farm due to seabed conditions that did not allow the use of suction buckets. The company plans to deploy the gravity jacket foundations anchored to the ground with suction buckets on future projects in deeper waters.

The commercial aspect of the offshore wind technology to be tested within the project is expected to show a significant positive impact on the Levelized Cost of Electricity (LCoE), according to Siemens.

Along with the new foundations, the company will install four of its 7MW direct drive wind turbines, as well as a new 66kV voltage solution including a new transformer, cable and switchgear systems, and further innovations regarding tower and controller settings.

Navantia-Windar will deliver the last Nissum Bredning jackets by mid-2017, with the turbine installation scheduled for summer 2017 and commissioning expected to take place in the third quarter of next year.

ITPEnergised Wraps Up Pinghai Bay Offshore Wind Farm Due Diligence Review for NDB

ITPEnergised, formerly IT Power Consulting, has completed its technical due diligence review of Phase 2 of the Putian Pinghai Bay offshore wind project in China on behalf of the New Development Bank (NDB).

ITPEnergised has provided advisory and due diligence review services to NDB, focused on the provision of sovereign loans for the Chinese offshore wind project with potential to provide over 250MW of new capacity.

In May 2016, ITPEnergised’s staff visited the project in China and met with the project companies to discuss the details of their proposed project.

ITPEnergised carried out due diligence reviews of the planning and feasibility work already undertaken and identified risks to the construction phase and future operation of the project.

Subsequently, in November 2016, the NDB approved a CNY 2 billion (EUR 273 million) loan for the new 250MW phase of the Putian Pinghai Bay offshore wind power project in Fujian Province, China.

This latest phase of the Pinghai Bay project will add to the existing 50MW phase 1, which features ten XEMC XE128-5MW, direct drives turbines, installed in around 10m of water depth and approximately 8km from the Chinese mainland.

Phase 1 was constructed during late 2015 and the first half of 2016 and has been fully commissioned since the summer of 2016.

The NDB’s loans to the Chinese state-owned project developers will help to ease the issues currently being experienced in China’s industry and accelerate the development progress.

Though the wind speeds in the provinces of Fujian are comparable to those found in European markets, the site, environmental, political, metocean, seabed and supply chain conditions are all very different and require a local approach rather than a direct replication of existing, international common practices.

K2 Advises ITOCHU on Butendiek Stake Purchase

K2 Management supported Japan’s ITOCHU Corporation in its 22.5% equity interest investment into the 288MW Butendiek offshore wind farm – its first investment in European offshore wind.

ITOCHU bought the stake in the wind farm from the Danish pension fund administrator PKA  for DKK 1 billion (EUR 134.5 million) in December 2016.

K2 Management provided technical and wind due diligence on the transaction, focusing on performance and technology, project life and long-term OpEx and O&M strategy.

Project Manager at ITOCHU Corporation, said: “This project represents ITOCHU Corporation’s first European offshore wind investment and K2 Management’s technical advice, financial insight and operational performance expertise was invaluable to us in this acquisition.”

Butendiek offshore wind farm, located in the German North Sea, has been operational since August 2015.

“Our core team consisted of experts with real hands-on offshore wind experience covering development, construction and operation of such projects – that experience enables us to deliver much more focused, value-adding supporting within the often short timescales of these transactions. It was great to work on this project again, as I led the lender’s technical advisor assignment for Butendiek when it secured debt finance prior to its construction,” Simon Luby, Head of Global Due Diligence at K2 Management, said.

Located 32km west of the island of Sylt, the EUR 1.3 billion Butendiek project comprises 80 Siemens SWT 3.6-120 turbines.

The wind farm has been developed and operated by wpd, and besides ITOCHU and wpd, investors include Marguerite Fund, Siemens Financial Services, Industriens Pension (IP), CDC Infrastructure, ewz (Elektrizitätswerk der Stadt Zürich – Zurich Electricity Works).

Marine Warranty Surveyor Wanted for COBRAcable is looking to pre-qualify companies which will participate in a tender for a Marine Warranty Surveyor contract worth EUR 600,000 for offshore cable laying and cable protection at the COBRAcable interconnector that will link Denmark and the Netherlands.

Danish transmission system operator will pre-qualify 3-5 applicants who are evaluated as most qualified and only these applicants will be invited to submit a tender. Interested parties can apply until 13 February.

The COBRAcable, being developed by TenneT and, will have a capacity of 700MW and will run from Eemshaven in the Netherlands, via the German sector of the North Sea to Endrup in Denmark. The interconnector will make Dutch capacity structurally available to the Danish electricity grid, and vice versa. It will also be designed in such a way as to enable the connection of an offshore wind farm at a later stage.

Prysmian is in charge of the turn-key supply and installation of an HVDC bipole cable – using single core cables with extruded insulation technology – that will operate at a voltage level of ±320 kV with a rating of approximately 700MW.

The interconnector will run along a total route of around 325 kilometres and will include two onshore lengths of 1 km on the Dutch side and 25 km on the Danish side to link to the onshore converter stations, which are to be provided under separate contract by Siemens.

Preparations for the construction of the converter stations at Eemshaven and Endrup have already started, with work on the construction of the cable due to start in mid-2017.

TenneT and will also install a fibre-optic data link alongside the COBRAcable interconnector itself, in order to exchange the necessary information about the interconnection.

LM Wind Power and ECN Develop Smart Blade Tips

Danish blade maker LM Wind Power and the Energy Research Centre of the Netherlands (ECN) have developed blade tips which are said to increase offshore wind farm yields.

“The design of an offshore turbine blade requires a different way of thinking for two reasons,” said Ozlem Ceyhan-Yilmaz of ECN.

“Firstly, there are fewer limitations to noise emission because there are no people living nearby. Secondly, the offshore challenge is to design rotors that will result in the largest power output for complete wind farms.”

To influence the wake behind the turbine, ECN and LM Wind Power designed a special tip for integral optimisation of turbines without considering noise limitations.

ECN has also developed a wake reduction tip with a zigzag shape which is said to increase turbulence in the boundary of the wake which increases the yield of offshore wind farms.

These designs were validated on 2.5MW-sized wind turbines at ECN’s wind turbine test facility in the Wieringermeer.

“This demonstration was unique. A full-scale experiment in an operating wind farm was performed. Then tips were installed on the blades of the wind turbines in such manner that they could be removed afterwards. The method for installation and removal has been an innovation by itself, and required close cooperation between ECN and LM Wind Power,” Ozlem said.

The results of the test at these 80m large rotor blades demonstrated that an increased farm power output up to six percent is achievable through blade tips. By using a new method, ECN made it possible to measure relatively small power increases.

“Great results are encouraging to continue designing models and demonstrating blade tips. Together we aim to lower costs of wind energy,” Ozlem said.

Senvion wins Portuguese framework

The deal will see Senvion supply turbines from its MM 2MW and 3.XM platforms to EDPR’s projects in Portugal, and to provide a minimum five years of servicing with an option to extend to 20 years. 

Senvion has a production facility in Portugal, which will supply most of the compontents. Details of projects that will benefit from the deal were not released.

“We are delighted to sign this contract with EDP Renewables… Senvion is particularly proud to be selected as their supplier for a major investment and in their home country Portugal,” said Senvion CEO Jurgen Geissinger.

Senvion has had limited penetration in Portugal with roughly 250MW installed in the country, according to Windpower Intelligence, the data division of Windpower Monthly.

In December 2014, Senvion won a deal with a local development consortium to supply 171.6MW from its 2MW product portfolio to five projects in the country.

Smulders Wins EOWDC Foundations Contract

Smulders Projects has won a contract to manufacture and assemble suction bucket foundations for Vattenfall’s European Offshore Wind Deployment Centre (EOWDC).

The company will manufacture lower parts of jacket structures and carry out the final assembly of the 11 foundations at its manufacturing facility in Newcastle which Smulders acquired from fabricator, OGN Group, at the end of last year.

Smulders was awarded the EOWDC contract by Boskalis which is the overall Tier 1 supplier of the scheme’s offshore balance of plant (BoP) work for the construction and installation (EPCI) of the offshore infrastructure including the foundations and cabling.

Taco Terpstra, project director at Boskalis, said: “The final assembly of the complete foundations at the site in Newcastle upon Tyne allows Boskalis a much shorter sailing distance from the load-out location to the site offshore with all benefits for our logistics chain.”

The 92.4MW EOWDC, off Aberdeen Bay, is believed to be one of the first UK offshore wind projects where suction buckets will be deployed on a large scale. Through being paired with 11 of the world’s most powerful turbines, the suction buckets will also create an industry first.

“This latest contract award follows successful trials of the game-changing buckets and as a leading fabrication specialist for the wind sector, we’re pleased that Smulders will be carrying out the assembly work in Newcastle,” Adam Ezzamel, project director for the EOWDC at Vattenfall, said.

”The buckets enable faster offshore installation of the EOWDC, while keeping noise to a minimum, and allow easier decommissioning as the installation process is reversed. As such, the technology will contribute to driving down the cost of clean power as offshore wind moves into deeper waters and more complex seabed conditions.”

Smulders’ 300,000m² manufacturing hub in Newcastle, which continues to support OGN’s operations, has facilities for constructing jackets and substations. Since taking it over, the company has also invested in additional lifting capacity including two gantry cranes which can each lift up to 600 tonnes. In addition, work is underway to install a large ring crane with a lifting capacity of 3,200 tonnes.

“We are convinced that with expanding our production platform with this new facility in Newcastle upon Tyne, we not only added local content in the UK and an additional production capacity within the Smulders group, but also have created an excellent base close to the renewable and offshore market within the UK,” David Muylaert, deputy managing director, at Smulders Group, said.

“In particular, for the Aberdeen Bay project, we are going to use this yard for the fabrication of the lower parts of the jacket structures and to do the final assembly of all associated parts. This has been made possible by means of the necessary investments in lifting facilities which we did on our yard.”

Smulders’ contract for the EOWDC is the latest in a series that have been awarded over the past six months for the project with a considerable extent of UK supply chain success. Other Tier 1 contractors appointed were MHI Vestas to supply the turbines and which is fabricating the 80m blades at its Isle of Wight factory while London-headquartered J Murphy and Sons Limited is providing the onshore substation and associated cabling work.

Hartlepool-based JDR is to deliver the 66kV inter-array and export cables, representing the first deployment of this innovative technology, and Babcock in Rosyth is deploying its floating LiDAR (light detection and ranging) technology to provide offshore wind data to the EOWDC.

Vattenfall has also signed leases totalling 24 years with Aberdeen Harbour Board, becoming the first offshore wind operator to invest long term in the port’s facilities.

The EOWDC is being developed by Vattenfall-owned company, Aberdeen Offshore Wind Farm Limited.
