4.1 – 113 Wind Turbine Brochure

GE Power & WaterRenewable Energy4.1-113Offshore Wind TurbineProven technology –built for purpose.23Proven technology… built for purposeGE’s 4.1-113 combines a proven design with GE’s unparalleled reliable technology to deliver a genuine offshore wind turbine. The robust baseline design is intended specifically for the offshore environment, with reliability and availability as the primary design drivers. This is why the machine includes a direct-drive drivetrain, redundancy in the generator and converter, and in-situ repair capabilities, the combination of which provides unique value to offshore wind farm operators.GE has a long history of successful product evolution with our onshore 1.5MW and 2.5MW platforms and we are taking the same approach with the offshore product line. By integrating improved cooling, carbon blades and GE’s patented Advanced Loads Control technology already proven in our onshore fleet, GE has evolved the turbine from a 3.5MW machine with a 90 meter rotor to a 4.1MW turbine with a 113 meter rotor. The combination of GE’s proven technology with the robust baseline design provides 43% more annual energy production while maintaining the track-record of the baseline design. On a monopile in water depths up to ~30m, this provides the optimum combination of low CAPEX plus highest yield.GE’s stringent design procedures result in a turbine intended and proven for high performance, reliability and availability. With six years operating history of the installed fleet of 3.5 MW turbines the design platform is well proven. In the harsh climate of coastal Norway, the fleet is already operating at availability levels higher than 97%. Such high availability results are due in part to its specific design and direct drive technology which means less maintenance downtime while reducing operating expenses significantly.GE’s overall wind power product strategy focuses on results vital to our customers’ success and the world’s energy needs. With a design strategy that emphasizes higher efficiency, increased reliability, maintainability and seamless grid integration, GE wind power solutions are ever-evolving powerhouses of precision.Technical Data: 4.1-113Operating Data• Rated Capacity: 4.1 MW• Cut-In Wind Speed: 3,5 m/s• Cut-Out Wind Speed: 25 m/s• Rated Wind Speed: 14 m/s• Wind Class – IEC: 1bFeatures• Rotor Diameter: 113 m• Swept Area: 9,940 m2“Plug & play” approach to offshore windThe logistical challenges of offshore installation, especially when compared to onshore projects, make it imperative to minimize the time spent offshore and thus reduce costs for our customers. GE’s 4.1-113 is building on the execution track-record GE has built onshore. With over 16,500 turbines installed, GE’s 1.5 series is recognized as the most easily installed and commissioned onshore turbine. GE’s 4.1-113 design takes ease of installation and commissioning to the next level. It allows for the machine to be connected, tested, and pre-commissioned in the factory prior to shipment.Upon installation a single bundle of cables is dropped from the turbine’s nacelle and connected to the switch gear, the only component that is configured down tower. Once the turbine is “crane ready”, the 4.1-113 should take no more than 7 days to install and commission which is a significant improvement on current market averages.4GE’s 4.1-113... Reliable PowerMaximizing availabilityAs one of the world’s leading wind turbine suppliers, GE provides support services extending from remote monitoring and fault resolution to complete operations and maintenance. Our field engineers remain dedicated to ensuring consistent turbine reliability. This knowledge has shaped GE’s offshore Service strategy... minimize time at sea by focusing wind turbine design on the realities of working offshore with a healthy respect for and understanding of the offshore environment and its challenges. GE’s 4.1-113 design was formed with a simple goal in mind: to design a wind turbine that was suited specifically for the offshore environment and delivering the lowest cost of electricity to customers. One key driver in lowering the cost of electricity is serviceability resulting in less downtime and more Annual Energy Production. That is why GE has placed such a heavy emphasis on designing in reliability and availability at the heart of the offshore turbine design. The 4.1-113 design eliminates maintenance-intensive parts of the yaw system and drive train, and will deliver lower operating expenses through longer intervals between planned maintenance and by minimizing the need for large jack-up barges through built-in modularity and redundancy.
