Growth prospects for wind turbine materials

The increasing demand for energy worldwide and traditional energy independence due to volatile oil prices is encouraging governments throughout the world to harness the potential of renewable energy, driving the global market for wind turbine materials. Expanding at a compound annual growth rate (CAGR) of 8.9%, the wind turbine materials market is likely to almost double, reaching US$19.57 billion by 2026 from US$10.76 billion in 2019.

“With the increasing population and economic development, global energy demand is rising rapidly. Many countries across the globe have been

Indonesia’s heaviest steam turbine generator

The expansion of Tanjung Jati B power station in Indonesia is a US$4.4billion project and will add two high efficiency ultra-supercritical coal-fired units, each with 1,000MW capacity. They will increase the existing power plant’s capacity by 75%, contributing to the Indonesian government’s plan to increase the country’s power generation capacity by 35,000MW.

ALE was contracted for the installation of a 462t generator at one of the new units. This was the heaviest steam turbine generator to ever be installed in Indonesia. The building’s design meant ALE needed

to design a bespoke solution for the installation of the generator. It needed to be carefully lifted 16m high, manoeuvred and then precisely installed. A gantry system with strand jacks was installed on skid tracks. Once the generator had been positioned on a trailer below the gantry, strand jacks were attached to the generator. The strand jacks lifted it until it was clear of the trailer.

ALE held the generator in position

for 30 minutes to check for any settlement of the ground beneath the skid tracks. Additionally, the gantry system was monitored by an electronic monitoring system. If its verticality moved more than 15mm from its original position, the load would be lowered and made safe again. Only when ALE was satisfied that it was safe to proceed did the team move to the next stage of the installation.

experiencing an energy gap, which is being broadened by the deliberate depletion of fossil fuels,” said Sayantan Sengupta, Visionary Science Research Analyst at Frost & Sullivan. “These factors urgently call for transforming the world’s traditional energy system with excessive uptake of energy-efficient renewables. In turn, this is expected to enhance the investments in the renewable energy sector, such as wind

power, thereby driving the demand for both structural and non-structural materials.”


Subsea technology specialist Rovco has successfully completed an extensive ROV inspection contract. The circa £1 million contract has resulted in completion of the baseline asset integrity survey at the newly constructed Galloper Offshore Wind Farm, a 353MW installed capacity wind farm that lies 30km off the coast of Suffolk, UK. The project, which was awarded

by Innogy Renewables UK, began in September 2019 – with 24-hour ROV operations provided over a four-week period. Rovco deployed a Cougar

XT ROV fitted with both 3D imaging sonar and SubSLAM 3D technology to complete planned asset inspection activities. 7
