Norfolk Marine’s TFN System Keeps Scroby Sands Turbines Grounded

Source: Norfolk Marine

Seabed levels around the five turbines fitted with Tyre Filled Net (TFN) scour remediation system units at the 60MW Scroby Sands offshore wind farm have risen, Norfolk Marine Ltd, the developer of the system, reports.

Monitoring has shown that pile stability has increased as the scour pits have filled with naturally occurring sediments trapped within the TFN units installed around the monopile foundations.

“The TFN system’s effectiveness in the mobile sandy seabed environment at Scroby Sands has been particularly good and eliminates the problems associated with rock dumping and sand bags in such conditions. The use of TFN’s is particularly suited to highly mobile sediment areas, where scour is usually a significant problem” said Norfolk Marine’s TFN Project Manager Laurie McCaughan.

The results show that the TFN’s have successfully reinstated seabed material around the turbines, where they are installed, and prevented further loss of material.

Their effectiveness in mitigating the risk from scouring has been proven at Scroby Sands, even where there is significant secondary scouring due to previous rock dumping activities, Norfolk Marine said.

Each TFN consists of 50 recycled tyres held inside a marine grade net. The tyres are tied together inside the net with ropes that provide a backup method of securing and recovering the tyres from the seabed. The tyres inside each net trap material which is suspended in the tidal water flow and prevent it escaping so the seabed is reinstated with naturally occurring sediment.

Scroby Sands is situated in the North Sea, some 2.5 kilometers off Great Yarmouth, UK. The wind farm, owned and operated by E.ON Climate & Renewables, comprises 30 V80-2.0 MW Vestas turbines.

Thereafter the vessel will continue with the winter installation campaign of the inner array grid cable system of the 402MW Veja Mate offshore wind farm in the German Bight.

Regis Rougier, Managing Director of Siem Offshore Contractors, said: “I am delighted to have the Siem Aimery in our fleet, with the Siem Moxie and the Siem Aimery working in tandem, we have the best of breed installation spread available. They are a unique team of vessels that will ensure that we safely deliver our projects on time for our customers. We are planning an event later this year, where we will invite customers to visit the Siem Aimery, right now our focus is on getting the vessel into the field for her first assignment.”

The Siem Aimery has been specifically designed and built for the installation and repair of medium and high voltage submarine cables. Having two carousels low in the vessel’s hull and a hangar-based cable deck, she is specifically designed to work in the adverse weather conditions. Siem Offshore Contractors has a long term charter agreement with Siem Offshore and will be responsible for the operations of the vessel.

Vestas suffers revenue dip despite record order intake

Earnings before interest and taxes (EBIT) increased by €6 million to €85 million in the three months to 31 March, Vestas reported.

Revenue fell 4% from €1.52 billion to €1.46 billion, which was attributed to a fall in turbine deliveries.

The record order total — up 37% year-on-year — was underpinned by the 1GW order placed by a Statkraft-led consortium for the revived Fosen cluster in Norway.

The six-project cluster will be located on the Fosen peninsula, the island of Hitra and Snillfjord municipality, on Norway’s west coast.

The state-owned utility and developer Statkraft said delivery of the 248 V117-3.45MW and 30 V112-3.45MW turbines was planned to begin in 2018. Vestas’ power mode will raise their output to 3.6MW each.

Due to its strong order book, Vestas’ turbine and servicing backlog amounted to €18 billion by the end of Q1 2016, up €3 billion on a year earlier.

Servicing revenue increased 17% year-on-year, following the acquisition of maintenance groups Availon and UpWind Solutions.

The manufacturer maintained its outlook for 2016 with revenue expected to reach €9 billion.

Cape Wind Fights Back

Source: Cape Wind

Cape Wind Associates has filed a court appeal against the Massachusetts Energy Facilities Siting Board’s decision not to extend the company’s permit for two subsea cables that would connect a 468MW offshore wind farm in Nantucket Sound to the mainland.

The board decided not to extend the permit by May 2017 based on the developer’s inability to demonstrate that the project will enter construction phase by mid-2017, adding that the construction was likely to be postponed further after Cape Wind lost key contracts with National Grid and Eversource Energy back in 2015.

The appeal, filed to the state’s Supreme Judicial Court, calls for reversal of the board’s decision.

Cape Wind Associates argues that the board’s decision not to approve a two-year permit extension was ”based on errors of law” and was ”made upon unlawful procedures.” The developer also said that the decision is ”unsupported by substantial evidence and lacks requisite subsidiary findings.”

In its appeal, Cape Wind Associates claim that in reaching the decision to deny the permit extension, the board overstepped its authority and interfered with the United States Bureau of Offshore Energy Management’s (BOEM) exclusive federal authority, as the project is located in federal waters and is ”outside of the boundaries and regulatory jurisdiction of the Commonwealth.”

Cape Wind Associates obtained the commercial lease to construct and operate the wind farm in October 2010. The project will consist of up to 130 Siemens 3.6MW wind turbine generators. The electricity generated from the project could provide about 75 percent of the electricity demand for Cape Cod and the Islands of Martha’s Vineyard and Nantucket.

The lease area covers approximately 46 square miles in Nantucket Sound, 25 square miles of which make up the project footprint area on Horseshoe Shoal. The lease includes a 5-year site assessment term and a 28-year operations term.

In February 2015, the developer submitted a request for a two-year suspension of the operations term of its commercial lease, which was approved by the Bureau of Ocean Energy Management (BOEM) in July 2015. No construction or installation activities related to the commercial lease may occur during the lease suspension period which expires in July 2017.

BOEM Guides Search for West Coast Tribal Cultural Landscapes

Source: BOEM

The US Bureau of Ocean Energy Management (BOEM) has issued a new guide to help government agencies and Native American communities work together to identify areas along the country’s west coast that could be affected by future offshore renewable energy development.

The potential for impacts to important coastal and marine Native American sites will increase as interest in offshore renewable energy development increases, BOEM says. These potential impacts may include physical disturbances to archaeological sites and traditional use areas, as well as visual impacts.

Utilizing a cultural landscape approach that integrates traditional knowledge with environmental science, historical information, and archaeological knowledge, the guide outlines a method for tribes with a connection to the coast to document places and resources significant to their communities. This approach and the data it yields are intended to reduce potential conflicts while filling critical data gaps in ocean planning and resource management.

“Understanding the types of important archaeological and cultural resources that could be affected is essential to their preservation,” said Joan Barminski, Pacific Regional Director of the Bureau of Ocean Energy Management.

“The approach outlined in this guide recognizes that places and cultural heritage resources can have different or multiple meanings and levels of significance based on how people from different cultures, times, or backgrounds have interacted and continue to engage with the respective landscape.”

A tribal cultural landscape approach is grounded in tribal sovereignty and identifies best practices for tribes on how to represent their interests to government agencies in reviewing potential development projects. It also outlines best practices for agencies on how to consult with tribes more effectively and appropriately in advance of proposed projects.

“The places we live are as much part of us as our songs, stories, foods and oral traditions. They remind us of our place in the world and our obligations. Finding ways for land managing agencies to see this importance – to help us protect them and preserve our cultures, is vital,” said Eirik Thorsgard, one of the project’s core members and tribal member of the Confederated Tribes of the Grand Ronde Community of Oregon and former Tribal Historic Preservation Officer for the Tribe.

“This set of methods and acceptance of understanding assists in training people from other cultures about our perspectives and ensures for generations to come, we will still have the world our elders gave us.”

The guide, Characterizing Tribal Cultural Landscapes, is available here.
