Highly Accelerated Life-cycle Test

HALT testing: Design verification and Life-time validation

The HALT test benches enable wind turbine manufacturers to test the function and life-cycle of different wind turbines faster and better than ever before at Lindø Offshore Renewables Center (LORC).

The HALT test bench and HALT XL test bench test the next generation of prototypes of the world’s largest offshore wind turbines to make sure that the enormous energy giants can withstand the scenarios out on the ocean. This requires a test bench out of the ordinary.

Both test benches are used for design verification and Highly Accelerated Life-time Testing (HALT) of nacelles as well as drive-train components such as gearboxes and main bearings.

R&D Test Systems has developed test benches that will expose the prototype to 20 years of the elements in just 6-8 months.

16 MW: HALT test bench

The 16 MW Test Facility can perform Highly Accelerated Life-cycle Testing (HALT) of components for wind turbines up to 10 MW.

The HALT test bench has a hydraulic Test Load Unit, which can add a bending moment of up to 25MNm to the test subject. In addition to this, the drive motor system and drivetrain can add a torque of 14.5MNm to the test subject.

25 MW: HALT XL test bench

The 25 MW Test Facility has a torque of 32 MNm and is placed on a 30 meters long concrete block and delivers a dynamic bending moment of 85 MNm. The HALT XL is the wind industry’s largest and most advanced test bench.

The test system provides a yaw-moment in the 65 MNm range where it will be testing the most power full offshore nacelles and drive-train components up to the 16-18 MW range and run functionality tests of nacelles up to about 20MW.

25 MW Test Facility at LORC

Previously, R&D Test Systems has developed and build test benches for LORC, including some of the largest in the world. Therefore, it has been the natural choice for us to seek competences, know-how, and especially the innovative approach, which R&D Test Systems can provide.
