Heavy Duty Weighing Service for Wind Turbine Structures

Heavy Duty Weighing Service for Wind Turbine Structures
HBM - Hottinger Baldwin Messtechnik GmbH (Germany) - The past several years has seen two major trends in the development of wind energy:
  • The first is a migration from onshore to offshore wind parks.
  • The second is the development of increasingly large structures that are needed in offshore operational conditions to meet the demand for vastly improved efficiency in energy generation.
A frequent challenge for operators is the requirement to measure the total mass of the structure so the correct support equipment, such as cranes and transport vessels, can be allocated prior to installation to minimize delays and vastly reduce costs. The size of support equipment and hiring costs are significant.

The Global Wind Organization (GWO) identifies four main sub-types of structural design for an offshore wind turbine. These are the Monopile, Jacket, Tripile and the Tripod that is particularly suitable for the harsh environmental conditions encountered.

Complete measuring service from HBM:
HBM offers a complete measuring service for these offshore structures based on its established C18 reference compressive force transducers with up to 5 MN load capacity per cell. These force transducers feature excellent repeatability and benefit from a classification option with a DAkkS calibration certificate as per ISO 376: Class 0.5.

The service is done in-situ while taking little time and HBM’s service team verifies the calculations before completion. Several customers have utilized this HBM Heavy Duty Weighing Service and expressed complete satisfaction.

HBM has been deeply involved in wind projects for over the past ten years and has been a key partner in some 20 large-scale projects over that period.

Alpha Ventus, Germany´s first wind park comprised six wind turbines constructed with a jacket structure and another six wind turbines with a Tripot structure. HBM was a key participant in the initial FINO and RAVE research on the Alpha Ventus framework that paved the way for Germany’s first offshore wind park.

HBM is also involved with a Tripod demonstrator for the Areva M5000 wind turbine that can be viewed in an onshore location at Bremerhaven in northern Germany.
