Deshalb ist eine flexible integrierte Logistiklösung erforderlich, um Wartung und Instandhaltung möglichst effizient zu gestalten.

Im Rahmen eines neuen Konzeptes werden speziell ausgelegte Offshore-Serviceschiffe (Service Operation Vessels, kurz SOVs) dabei helfen, diese Herausforderung zu meistern. Sie werden neue Maßstäbe für die Wartung von Offshore-Windparks setzen.

(WK-intern) – Siemens ist das erste Unternehmen, das dieses vielseitige Offshore-Logistikkonzept anbietet. Das erste, speziell dafür ausgelegte Serviceschiff wird 2015 zur Verfügung stehen.

Siemens’ new service operation vessels are making waves in the industry

Offshore wind power has come of age. Costs have come down, turbines have become more efficient, and with a generating capacity of hundreds of megawatts, today’s offshore wind power plants are on their way to being on par with many conventional power plants. And just like conventional power plants, these huge farms of sea-based wind turbines need on-site maintenance over their full lifecycle in order to ensure the highest availability.

But servicing offshore wind turbines can be challenging. Next-generation plants are larger and farther from shore, making them difficult to access – particularly during rough weather.

Starting in 2015, Siemens will revolutionize offshore wind turbine service with its new service operation vessels (SOVs). Packed from stern to bow with state-of-the-art features and technology, they will greatly reduce the risks involved with weather, they will be located on site, and they will offer swimming workshops. In a nutshell: The next generation of offshore wind service will be safer, faster, and more reliable.

Something exciting is in the air
Patrick Klause is a modern-day seaman who gets a kick out of being out at sea and battling the forces of nature. Naturally, a 9-to-5 job was not his style, so the young technician joined the Siemens offshore wind service team. When Siemens’ new SOVs begin operation in 2015, Patrick Klause will be among the first technicians living and working on these vessels. And he will be servicing offshore wind turbines in weather conditions that used to mean a day off for all offshore wind service staff. Patrick Klause knows exactly what to expect: “The weather conditions out here are sometimes unpredictable and pretty harsh,” he says while he is out at sea on one of the vessels. “Servicing offshore wind turbines is a unique challenge. But I never wanted an ordinary job; I wanted something exciting.”

Man-high waves are not an obstacle
The new vessels will provide direct and safe access to the turbines in varying wave conditions using an advanced hydraulic gangway system. Technicians will be able to literally “walk to work” safely in seas of up to 2.5 meters. Waves of this height are caused by strong breezes of Beaufort force 6 and wind speeds of 22-27 knots. Onshore, winds of such force make telephone wires sing. With the conventional boat landing methods that were formerly used for offshore wind turbine maintenance purposes, safe access to the turbines was only possible at wave heights of up to 1.5 meters. The SOVs storage facilities allow common spare parts to be stocked offshore, close to the wind farm. The SOVs will also provide accommodations for more than 30 Siemens technicians for several weeks at a time, enabling them to live and work at the project site and to spend less time traveling to and from shore.

A new dimension of efficiency
The new, state-of-the-art design concept has been developed with a strong focus on advancing and streamlining Siemens’ offshore service operations and logistics for the customers’ benefit. Less time traveling to and from shore allows for more time at the site and a more efficient and cost-effective use of resources – even more so since the vessels will be strategically positioned in close proximity to the wind turbines for easier access and operations. And the SOVs will also be able to stay in the field for several weeks at a time, and only need to return to port for fueling and the replenishment of supplies and equipment. Customers will benefit from Siemens‘ emphasis on a more effective use of resources and personnel, as well as better accessibility with less time lost waiting for a suitable weather window.
