German output drops due to slower winds

The decline in onshore wind generation and similarly poor figures for solar (-2.1% year-on-year) meant total electricity generation from renewable energy sources (+0.2%) remained largely constant, according to the Bundesnetzagentur (BNA).

This decline in power production hit operators’ earnings in 2016, BNA figures show.

Payments to operators of onshore wind farms under the German Renewable Energy Act (EEG) fell to €4.69 billion. This marks a drop of 7.7% when compared to 2015 — the greatest reduction in payment for all renewable energy operators.

However, offshore operators’ earnings rose to €1.95 billion — the 54.3% increase year-on-year being the largest rise in payments for all renewable sources.

“The year 2016 shows once again that the power generation in Germany is subject to constant change,” said Jochen Homann, president of BNA.

“2016 was a poor wind year, so the production of electricity from renewable energy rose only slightly.”

Average land speeds in Germany dropped from about 6.6m/s in 2015 to roughly 6.1m/s in 2016, according to the BNA. This decline in wind speeds was felt even more acutely in northern Germany, where speeds fell from roughly 8m/s to about 7.3m/s.

Together, these slowed speeds contributed to a 4.6TWh drop in power output from onshore wind farms, the BNA concluded.

Meanwhile, driven by an increase in offshore capacity, offshore production in 2016 increased 48.1% year-on-year.

Offshore wind farms with a combined capacity of 848.7MW were installed in 2016 — an increase of 25.8% to the cumulative total as of 31 December 2015, according to the BNA.

This increase — the sharpest rise of all renewable sources in 2016 — meant the output from offshore projects increase 48.1% year-on-year.

Although onshore capacity grew by 4.16GW in 2016 — a 10.1% increase on the cumulative capacity at the end of the previous — both production and revenue decreased for wind farm operators.

EMO Starts Building Merkur Service Base in Eemshaven

EMS Maritime Offshore (EMO) has laid the foundation for the Merkur offshore wind farm service base in Eemshaven, the Netherlands.

BV Kooi Bouwbedrijf, the general contractor for the construction work, will build a 600 m² warehouse, affiliated offices covering 500 m² spread across two floors, as well as the terminal logistics.

Merkur Offshore GmbH, the developer of the German 396MW Merkur offshore wind farm, signed a long-term contract with EMO in October 2017 for the construction of the service base in Eemshaven.

“Eemshaven is an excellent location for supervising the equipment in the wind farm effectively. It was important for us to find a partner whose service, competence, and flexibility were convincing,” said Markus van Hümmel, Head of Commissioning and Operations at Merkur Offshore GmbH.

The project, worth approximately EUR 1.4 million, is expected to be completed in the spring of 2018, when Merkur Offshore will start carrying out part of its maintenance and service works for the offshore wind farm from Eemshaven.

GE Renewable Energy, the provider of 66 Haliade 6MW wind turbines for Merkur, will also use the entire infrastructure for the upcoming years.

The Merkur offshore wind farm, located approximately 35km north of the island of Borkum in Germany, is expected to be fully operational in 2019.

VBMS and Kintech Energy Introduce Resin-Free Hang-Offs

VBMS and Kintech Energy Ltd. have jointly developed a resin-free hang-off solution for fixing and sealing subsea cables in offshore structures which could potentially be used on the Horns Rev 3 wind farm off Denmark. 

VBMS describes the new product as ”a sustainable solution for fixing and sealing subsea cables in offshore structures by offering a hang-off that features fast (dis)assembly without the use of toxic resins.”

Until now, hang-offs were assembled using – often toxic – resin, which can be harmful to both human health and the environment, VBMS said.

With its resin-free hang-off, VBMS is said to offer a safe, rapid and reusable solution when, for example, demounting a cable from a monopile or jacket for replacement.

Arno van Poppel, Managing Director of VBMS, said: “As a total solution provider in the renewables sector, we continuously think of ways to improve safety and efficiency and to reduce the operational risk for our clients. For this latest innovation we have cooperated with our partner Kintech Energy Ltd., a start-up enterprise from the UK. We believe it is important to invest in new market entrants and stimulate innovation within the supply chain.”

Vattenfall Vindkraft A/S, the developer of the 407MW Horns Rev 3 offshore wind farm, has shown interest and is currently exploring the options for using the resin-free hang-off on the project next year.

“Vattenfall is a true supporter of innovations that increase overall environment protection, safety and reduce risk. We are convinced that together with the supply chain we can set a higher standard in our industry,” said Horns Rev 3 Project Director Jens Hansen from Vattenfall.

In June 2016, Vattenfall awarded VBMS with a contract for the supply, installation, CPS, post-lay burial, termination and testing of the inter-array cables on the wind farm.

MMT Starts Aquind Interconnector Geophysical Survey

MMT has begun the offshore geophysical survey of the proposed cable corridor between the landfall areas near Portsmouth, England, and Dieppe, France, for the Aquind Interconnector project.

MMT will use M/V Franklin for offshore works and M/V Seabeam for nearshore works, both equipped with multibeam echo sounders, side-scan sonars and sub-bottom profilers.

According to MMT, the survey results will inform the UK and French authorities on Aquind’s final route selection and support planning applications.

The two companies maintain ongoing contact with UK and French fisheries, which may be affected by the survey, in order to mitigate any potential impact on their fishing activities, MMT said, adding that Aquind and its advisors are liaising with relevant consent granting bodies in both countries to ensure that the survey scope complies with applicable standards.

Stefan Eliasson, MMT’s CEO, said: “We are delighted to have the opportunity to support the AQUIND Interconnector project work and look forward to working with the Aquind Team to deliver a successful marine survey campaign along the proposed cable corridor. This shows that MMT can provide our customer with effective, high quality survey solutions meeting their high requirements.”

Aquind Interconnector is a new proposed subsea and underground High-Voltage Direct Current (HVDC) power transmission link between the south coast of England and Normandy in France.

With its 2,000MW capacity, the interconnector will transmit 16,000,000MWh of electricity each year between the two connected countries, which is 5 percent and 3 percent of the total consumption of Great Britain and France respectively, i.e. consumption by millions of households.

According to Aquind, by linking the British and French electric power grids, the interconnector will make energy markets more efficient, improve security of supply and enable greater flexibility as power grids evolve to adapt to different sources of renewable energy and changes in demand trends.
