Keeping the Noise Down Under the Sea

A pinwheel sits in an aquarium to simulate an offshore wind turbine. Bubbles come up from the "seabed" to encircle it to demonstrate a bubble curtain with an image of a sound waveform overlaid with the video to show the sound confined to the area within the bubble curtain.

Since sound is the primary sense used by most ocean life, disruptions to the natural noise levels in the ocean from human activities can be particularly problematic for marine life. …read more Continue reading Keeping the Noise Down Under the Sea

Pivoting arms could stabilize massive floating offshore wind turbines

As we’ve discussed many times before, offshore wind represents an enormous opportunity for clean energy, but some of the best resources are out in deep water, where sinking a shaft straight into the sea bed becomes prohibitively expensive and difficult… Continue reading Pivoting arms could stabilize massive floating offshore wind turbines

World’s new largest wind turbine sweeps 10 football fields per spin

A rendering of the CSSC Haizhuang H260-18MW, the world's largest wind turbine, which is currently under construction in China

The China State Shipbuilding Corporation (CSSC) is upping the ante on offshore wind, announcing it’s building the largest and most powerful wind turbine ever, making a peak 18 megawatts with an enormous 260-meter (853-ft) diameter on its three-bladed rotor.

Full-scale 5-MW floating “pyramid” wind turbine will be put to the test

Floating wind turbines are crucial to the future of offshore wind, and to bring energy costs down to a competitive level, they require radically different thinking. French company Eolink is starting to build a full-scale demonstrator of its innovative … Continue reading Full-scale 5-MW floating “pyramid” wind turbine will be put to the test

Record energy haul: Offshore prototype operates over capacity for 24 hrs

A prototype wind turbine has recorded an extraordinary single-day renewable energy production total, bringing in a massive 359 megawatt-hours in a 24-hour time period. To get there, it had to operate over its rated capacity, essentially all day long.Co… Continue reading Record energy haul: Offshore prototype operates over capacity for 24 hrs

1-MW floating vertical axis wind turbine to be deployed off Norway

We’ve been banging on a bit about floating offshore wind turbines lately, but with good reason. Take a look at the US Energy Information Administration’s projected Levelized Cost of Energy (LCoE) figures for 2027, on page 9 of this report. Deep offshor… Continue reading 1-MW floating vertical axis wind turbine to be deployed off Norway

Contra-rotating floating turbines promise unprecedented scale and power

Norway’s World Wide Wind has a radically different take on offshore wind power. These floating, vertical-axis wind turbines (VAWTs) feature two sets of blades, tuned to contra-rotate – and they promise more than double the output of today’s biggest tur… Continue reading Contra-rotating floating turbines promise unprecedented scale and power

Wind turbine fitted with recyclable blades starts generating electricity

Harvesting wind energy is an important part of the renewables mix, but when those huge turbine blades reach the end of their working lives, they could end up as waste in landfill. Siemens Gamesa has developed a recyclable blade that can be used to crea… Continue reading Wind turbine fitted with recyclable blades starts generating electricity

Argus unmanned surface vessel designed for accurate ocean mapping

Norway’s Argeo has launched the first uncrewed survey and inspection vessel based on the Mariner X platform from Maritime Robotics. The Argus is expected to undertake mapping and inspection operations for offshore wind projects.Continue ReadingCategory… Continue reading Argus unmanned surface vessel designed for accurate ocean mapping
