Grey evening with rain clouds looming in the background, the building on the left is the Marine Board Building with wind turbines atop, installed the middle of last year not without incident but all fixed now.


Four new wind turbines will be put in place on top of Hobart's Marine Board Building in the next few weeks.


The original turbines broke down in high winds last August, after a braking mechanism failed.


An investigation found a contractor didn't reset the mechanism after carrying out maintenance work.


The project manager Keith Drew says work is being done to prepare the building and then a crane will put them in place.


"Within the next few weeks we'll see some scaffolding go up around the existing turbine poles and they'll be removing the two turbines that are up there at the moment," he said.


"Then four new turbines will be installed on poles at the top of the building."


He says the system has been extensively reviewed to make sure it the mechanism does not fail again.


"We've had a complete review of the safety procedures to do with people turning the turbines on and off and we've upgraded the control systems quite extensively and that's been a fairly involved research and development exercise between the supplier of the turbines in China and the installer of the turbines which is a Hobart company
