Submerged tidal turbine goes with the flow on green energy

Compact oil immersed hydraulic brake units are enabling renewable energy turbines to make the most of energy production from sub sea tidal flows

Novel strategies boost turbine efficiency

The challenge of keeping power plants at peak efficiency - when demand is growing and investment is in short supply - is forcing plant managers and equipment suppliers to consider all aspects of their operations. Sean Ottewell reports

3D scanners deliver metrology for larger free-form objects

Developed to cope with measuring and inspecting cars, planes, trains, wind turbines in crowded production areas

Measurement of underwater noise

Fugro teams up with JASCO Applied Sciences, the underwater acoustics company, to provide measurement of underwater noise

Floating power station runs on heavy fuel or gas

Converted from bulk carriers has a 14MW generation capacity, says energy company Karadeniz Powership Co

Five offshore demonstration wind turbines planned

GE Energy teams up with Norwegian and Swedish energy companies in growing offshore wind farm sector developments

Novel sensors and turbine development

Sensor Technology's non-contact RWT320 units depend for their operation on surface acoustic wave transducers

Braking ideas for yaw and pitch of wind turbines

Brakes are key on a wind turbine. A turbine structure will require rotor, yaw control and blade pitch control brakes

Repair assessment and modification of gas turbine components and assemblies

Gas turbine components have different life-limiting failure modes. Life-limiting deterioration is frequently created by a detail of a component. A thorough analysis and creative thinking can lead to modifications that result in substantial extensions of turbine lifetime. Sief Mattheij reports

Couplings make the connection for gas turbines

Couplings to be installed, and the flexible elements (disc packs) changed, without disturbing adjacent machinery

Developing markets drive turbine innovation

A raft of joint ventures and new manufacturing centres highlight how investment in turbine technology is becoming focused on the major markets

Outlook optimistic for Europe’s power sector in 2011

But opinion divided on business benefits of single European electricity market

Air filtration challenges in the power sector

Fouling is costly, either due to the loss of power, the 'extra' fuel cost and/or the necessary standstill for water wash or other maintenance work. Peter Sandberg reports.

Turbine lubricants: meeting the latest challenges

The latest methodologies in tribology - the science of lubricants - is now helping to develop new technology that can deliver trouble-free service and improved efficiency levels for turbine lubrication. Ronald Bakker reports

Achieve oil drain intervals of more than 16,000 hours

Energy-efficient oil delivers reduced fuel costs and increased oil life

Floating power station

Self-contained power barge that can be positioned in ports, on rivers or in sheltered coastal locations
