Offshore but Centre Stage: A Key Role in the North Sea

By the end of 2012, the first German households will be tapping “green” electricity sourced from a major new wind farm built 45 kilometres offshore the North Sea island of Borkum.

Linking Offshore Design Tools

Standard approaches for designing offshore jacket structures are not optimised for wind turbine applications. GL Garrad Hassan offers a “third way”.

Ships for the Energy Revolution

There is great demand for installation vessels for the erection of offshore wind farms. GL is playing a leading role in this innovative market.

Fresh Winds at Great Heights

According to GL Garrad Hassan’s new market report on high altitude wind energy, kites, gliders and other flying tethered objects have the potential to take energy generation from wind into a new dimension.

Underwater Welding

Offshore structures are exposed to a hostile environment. The steel elements must be carefully maintained to avoid premature failure. A look at a fascinating welding technique.

Smart Testing for Wind Turbines

Power grids must be flexible enough to handle voltage dips. Low-voltage ride-through capabilities enable wind turbines to respond to such events intelligently. But testing these capabilities is quite a challenge.

Optimal Testing Conditions

Small wind turbine mod. TN535 developed by Tozzi Nord is now undergoing a six-month test at GL Garrad Hassan’s WINDTEST Measurement Centre located on Germany’s North Sea coast.

Measuring Real Wind Turbine Reliability

Reliability is the core concern for every wind turbine operator. Understanding the key factors for reliable operation requires careful analysis of measurements and turbine failure data.

Taming the Tides

Tidal energy is a vast resource man has yet to harness.
GL contributes its expertise by certifying tidal turbine prototypes. A look at an exciting project for Scotland.

“Brace, Brace, Brace!”

Helicopter transport is an important way of reaching offshore wind farms. Before getting on board, however, you must first pass a certified safety training course.

Rules of the Art

Repairing the tower components for offshore wind turbines is a complicated matter. GL Renewables Certification provides technical support and monitors the work.
