Tempest Hits Underwater Object at Kentish Flats

RNLI crews from Whitstable and Sheerness were called around 9.50am on 30 March to assist the Tempest crew transfer vessel (CTV), which had struck an unknown underwater object and was taking in water at the Kentish Flats offshore wind farm area.

There were 6 people on board the crew transfer vessel.

While Tempest was still impaled on a submerged object, Whitstable lifeboat arrived and transferred two crew members and a salvage pump onboard Tempest, followed by the same action done by the Sheerness lifeboat. Four wind farm technicians were transferred to another wind farm vessel that had also been standing by.

After the water had been pumped out, both lifeboats with their crews waited to see if the vessel would come free. Once free, it did not appear that the water ingress was getting any worse so, with the damaged compartment sealed, the skipper got the vessel underway and at slow speed made for Whitstable with both lifeboats escorting it.

“By 11.50am the Tempest had floated clear of the underwater object and the crews were able to assess the damage and the vessel then made its own way to Whitstable Harbour escorted by both lifeboats and was eventually secured alongside the west quay,” said Whitstable Lifeboat helmsman Dave Parry.

Statkraft to Start Divesting Sheringham Shoal, Dudgeon Shares in June

After fulfilling one of the prerequisites for the sale of its 40% share in the Sheringham Shoal offshore wind farm by transferring the operator role to Statoil, Statkraft will commence the formal divestment process in June, together with that for its 30% share in the Dudgeon offshore wind farm.

Earlier in March, Statkraft sold its 25% interest in the 4.8GW Dogger Bank offshore wind projects to partners Statoil and SSE, for which the company said is in line with its strategy to explore opportunities to exit the ownership of offshore wind power assets.

However, Statkraft said that the UK offshore wind sector presents a significant opportunity to develop a secure, sustainable, cost-competitive energy source and that  it remains open to new power purchase agreements. For Sheringham Shoal, Statkraft holds a power purchase agreement which extends until November 2029.

The company is also a 50% partner in the Triton Knoll offshore wind project and will continue working with innogy to develop the project towards an investment decision before bringing in new owners.

Offshore Wind Capacity: World – 14.1GW, Europe – 12.5GW

According to the latest statistics released by the International Renewable Energy Agency (IRENA), 2016 ended with a total of 14,081MW of offshore wind capacity in the world, 12,471MW of which has been installed in Europe. 

Asia accounted for 1,581MW of offshore wind capacity, while North America was listed with 29MW – attributed to the Block Island Wind Farm.

Among the European countries, the UK is leading with having an estimated 5,150MW of offshore wind at the end of the last year, followed by Germany’s 4,108MW and 1,271MW in Denmark, with the Netherlands nearing the four-figure team with its 957MW.

In 2015, offshore wind capacity was at 11,637MW worldwide, while Europe accounted for 11,014MW.

When it comes to other marine renewable energy technologies, together they reached a capacity of 536MW at the end of 2016, only 3MW more than reported for the year before, according to the statistics.

Overall, global renewable energy generation capacity increased by 161GW in 2016, making the strongest year ever for new capacity additions, the Renewable Energy Capacity Statistics 2017 show.

“We are witnessing an energy transformation taking hold around the world, and this is reflected in another year of record breaking additions in new renewable energy capacity,” said IRENA Director-General Adnan Z. Amin. “This growth in deployment emphasizes the increasingly strong business case for renewables which also have multiple socio-economic benefits in terms of fueling economic growth, creating jobs and improving human welfare and the environment. But accelerating this momentum will require additional investment in order to move decisively towards decarbonising the energy sector and meet climate objectives. This new data is an encouraging sign that though there is much yet to do, we are on the right path.”

Statoil Opens New Chapter as Sheringham Shoal Operator

Norwegian energy company Statoil will take over the operatorship of the 317MW Sheringham Shoal offshore wind farm from compatriot Statkraft on Saturday, 1 April.

This will be the first time for Statoil to run an offshore wind farm during commercial operations, the company said.

Statkraft intends to sell its 40% share in the Sheringham Shoal offshore wind farm, and one of the prerequisites for the completion of the sale is for Statkraft to transfer the role of the wind farm’s operator.

Statoil and Statkraft signed a letter of intent for the operator role to be transferred to Statoil in September 2016.

At the same time, the companies agreed on Statoil acquiring a portion of Statkraft’s 25% stake in the 4.8GW Dogger Bank projects, a deal which was completed earlier this month.

Last year, Statkraft announced plans to divest all of its offshore wind assets in the UK, including its shares in the operating Sheringham Shoal, and the 30% stake in the Dudgeon offshore wind farm, currently under construction.

The company is also a 50% partner in the Triton Knoll offshore wind project and remains committed to working with innogy to develop the project towards an investment decision before bringing in new owners.

Second Walney Extension Offshore Substation Leaves Hoboken

The second offshore substation built by the Engie Fabricom/Iemants consortium for DONG Energy’s 660MW Walney Extension wind farm has set sail from the Engie Fabricom site in Hoboken, Belgium, bound for the wind farm in the Irish Sea.

Standing 35 metres tall and weighing in at 2,900 tonnes, the Walney 4 is the second substation to leave the ENGIE Fabricom site this month.

The substation was accompanied by its 48-metre-high jacket foundation. The jacket was fully assembled on the Iemants site in Vlissingen in the Netherlands and then transported to Hoboken earlier this month.

Race Bank 1 and Walney 3 also left Belgium earlier this month.

The 367.2MW Walney wind farm in the Irish Sea, 19km off the coast of Cumbria, already comprises two substations. It is currently being expanded to include two additional substations, making it the largest offshore wind farm in Europe, with the expansion due to commission in 2018.

DONG Energy awarded the contract for building five substations to the Engie Fabricom/Iemants consortium. Engie Fabricom is in charge of the entire construction and commissioning on site, while Iemants is responsible for the steel construction work on the five substations and their jacket foundations. The Burbo Bank and Race Bank 2 substations were shipped last year.

Engie Axima – the expert in HVAC, cooling and fire safety within the Engie Group – was also involved in building the five substations ordered by Dong Energy. It delivered five rooftop units with a capacity of 4000 m³/h for treating fresh air, as well as 56 air conditioning cabinets and associated condensing units.

Trelleborg Puts NjordGuard CPS Through Paces

Trelleborg’s offshore operation has completed a series of wet tests to verify the capabilities and functionality of its NjordGuard cable protection system (CPS) for installation and removal on J-tube and monopile interfaces for offshore wind farms.

In addition to passing all the tests, NjordGuard was installed and removed from the test rig without the intervention of a remotely operated vehicle (ROV), Trelleborg said.

The testing took place at the Offshore Renewable Energy (ORE) Catapult’s National Renewable Energy Centre, an open access shallow water testing facility located in Blyth, England. The facility has been testing subsea equipment since 2002 and contains an artificial seabed and two still water test tanks. Trelleborg was able to perform eight full scale wet tests of NjordGuard covering a range of installation scenarios without having to go offshore.

“Deemed a complete success, the tests definitively prove NjordGuard™ is capable of installing into both monopile and J-tube openings and can be successfully removed without the need for ROVs,” John Deasey, Renewables Sales Manager at Trelleborg’s offshore operation based in the UK, said.

“The test results provided a greater understanding of potential installation issues our customers might face such as pull-in and pull-out loads. We also gained valuable insights into the dynamics of the system to help further refine and optimize our designs to optimize performance for our customer’s critical applications. Currently available to the market for both array and export cables, further testing of NjordGuard™ will be an integral part of developing and enhancing the solution to meet our customer needs and further highlights our commitment to supporting renewable energy projects.”

DMA Analyses Offshore Wind CTV Safety

The Danish Maritime Authority (DMA) has issued a report on safety analysis for high-speed offshore vessels carrying up to 60 persons, which can be used to harmonise safety on board offshore vessels carrying wind turbine technicians.

With the report’s release, DMA said it is striving to make the International Maritime Organisation (IMO) develop international standards.

The report is a result of two workshops with experts from the offshore wind industry, hosted by DMA and DNV GL, at which a safety analysis was made for vessels carrying wind turbine technicians. The objective was to identify all hazards and risk-reducing measures for Crew Transfer Vessels (CTV) related to the increase of number of persons on board.

The normal operations of this vessel type have resulted in a risk scenario considerably different from that of both ordinary cargo ships and passenger ships, according to DMA. Major risks are related to:

  • fire
  • hull and accommodation integrity
  • stability
  • man-over-board
  • incorrect handling and storage of dangerous goods
  • unsuccessful evacuation and rescue.

The intended safety standard should mitigate the particular hazards this type of vessels encounter due to the nature of their operations and the increased number of persons on board. The current regulations only allow for up to 12 passengers on board, but there is a need in the industry to increase this number. A possible new safety standard shall therefore be applicable for up to 60 persons on board, including 12 passengers.

Per Sønderstrup, Director of the Danish Maritime Authority said: “The safety analysis shows that there is good reason to focus on safety on board these vessels and it provides important insights into these special ship operations. We will use the report to harmonise the safety standards of vessels carrying wind turbine technicians.”

The safety analysis was made as a follow-up on the report that the Danish Maritime Authority published in January 2016, which identified the regulations and industry standards applicable to maritime operations in the Danish, British, German, and Dutch offshore wind sector. The 2016 report showed that there is a special need to harmonise the safety standards of ships carrying turbine technicians.

The Danish Maritime Authority said it will continue its work in the IMO drafting a common international safety standard for the carriage of offshore technicians.
