by ARATA YAMAMOTO for NBC News: Engineers in Japan have installed the world's largest floating wind turbine, a towering 344-foot structure that is billed as being able to withstand 65-foot waves and even tsunamis.
The 7 megawatt turbine was fastened to the seabed last week by four 20-ton anchors about 12 miles off the Fukushima coast.
Its installation was delayed four times because of consecutive typhoons in the region. But one of its chief engineers, Katsunobu Shimizu, told NBC News that the turbine — which is about the same height as London's St. Paul's Cathedral — would be able to withstand even the most extreme conditions.
"These turbines and anchors are designed to withstand 65-foot waves," Shimizu said during a sea tour of the turbine given from a boat off the coast. "Also, here we can get 32-foot-tall tsunamis. That's why the chains are deliberately slackened."
If a large wave were to push the turbine up, down or to the side, the loose chains connecting the structure to the seabed would give it the freedom to move without being damaged, he said. Cont'd...
By Madeleine Cuff for Business Green: The offshore wind industry is set for a bumper 12 months, as the latest figures from the European Wind Energy Association (EWEA) reveal installations in the first half of this year hit record levels.
As several projects reached completion and larger, more powerful turbines were deployed, new installations hit 2,342.9MW, triple the grid-connected capacity added in the same period last year. The surge in new projects makes the first six months of 2015 more successful than any other full year on record, in terms of installed capacity.
Some 584 new offshore wind turbines have been connected to the European grid so far this year, while the average turbine size has risen from 3.5MW to 4.2MW as manufacturers continue to develop more powerful turbines capable of capturing greater amounts of wind energy, the report said. Total offshore wind capacity across Europe has now reached 10,393.6MW, it added. Cont'd...
