Siemens signs chartering agreement for two new offshore wind service operation vessels

Innovative concept expected to offer significant advancements in logistics, design and safety

Siemens Energy has signed a chartering agreement with ship owner Esvagt A/S for two new offshore wind service vessels that will incorporate significant advancements in logistics, efficiency and operational capabilities. The vessels are being commis-sioned specifically for Siemens' service operations at the Butendiek and Baltic II offshore wind power plants in Germany, both of which are scheduled to come online in 2015. Siemens and Esvagt A/S met this week in Esbjerg, Denmark, to commemo-rate the project start and sign the chartering agreement.

As the industry leader in offshore wind service and recognizing the benefits a spe-cialized logistics concept could provide, Siemens has provided input to help in the vessel design and specifications over the last several months. Rather than the float-ing hotels that use smaller vessels or helicopters to access the turbines, the new vessels will provide direct access using an advanced hydraulic gangway system that will work to stabilize and provide safe access to the turbines at varying wave condi-tions. They will also include accommodations for more than 30 technicians for sev-eral weeks at a time, enabling them to live and work at the project site and to spend less time traveling to and from shore.

With its ongoing focus on intelligent innovation, Siemens Energy is embarking on this new design concept that, when completed, is poised to be the new standard for offshore wind service. Ship owner Esvagt A/S plans to construct the two highly ad-vanced offshore service operations vessels (SOV) from the ground up incorporating the latest in advanced logistics, design and safety for providing service and mainte-nance at offshore locations, particularly those located very far from shore. The ves-sels will serve as floating offshore accommodation platforms with spare parts stor-age and on-site office space.

"With more than 20 years experience in servicing offshore wind turbines, meeting the unique challenges within an often harsh, unpredictable marine environment is our core expertise," said Tim Holt, CEO of Siemens Energy's Service Renewables business. "This new, state-of-the-art design concept has been developed with a strong focus on advancing and streamlining our offshore service operations and logistics for the benefit of our customers. Less time traveling to and from shore al-lows for more time at the site and a more efficient and cost-effective use of re-sources. Our charter agreement with Esvagt offers us the opportunity to combine our leadership position with that of an experienced ship company," continued Holt.

The vessels will be strategically positioned in close proximity to the wind turbines for easier access and more streamlined operations. Via the hydraulically stabilized gangway technicians are enabled to literally "walk to work". Moreover, an SOV has the ability to stay in the field for several weeks at a time, only needing to return to port for fueling and the replenishment of supplies and equipment. Customers will benefit from Siemens' emphasis on more effective use of resources and personnel, as well as better accessibility with less time lost waiting for a suitable weather win-dow.

Within the framework of providing service for both wind power plants via long-term service agreements, Siemens signed the chartering contract with Esvagt A/S for the use of both service operation vessels. The construction of the vessels is scheduled to start this month at the Havyard Shipyard in Norway with launch anticipated for early 2015. When completed, each vessel will measure 84 meters in length with a maxi-mum speed of 14 knots.

Both vessels will be built with a continuous main deck and superstructure where the accommodations for the technicians are located. Modern cabins, meeting facilities, an exercise area and entertainment options also contribute to the comfort of the service technicians who will live and work on the vessel. Each vessel will carry spare parts for wind turbine maintenance in standard 20-foot containers on the ship's cargo deck. Siemens' BlueDrive™ propulsion system will be used to reduce CO2 emissions and fuel consumption.

Wind power and wind power service are part of Siemens' Environmental Portfolio. In fiscal 2012, revenue from the Portfolio totaled about 33 billion, making Siemens one of the world's largest suppliers of ecofriendly technologies. In the same period, our products and solutions enabled customers to reduce their carbon dioxide (CO2) emissions by more than 330 million tons, an amount equal to the total annual CO2 emissions of Berlin, Delhi, Hong Kong, Istanbul, London, New York, Singapore and Tokyo.

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
