The advantage of grouting is that it allows for Monopile minor misalignment resulting in better Tower vertical alignment.<br /><br />Shear keys are not "pins" and the cause of leaving them out was inexperience, not "incorrect numerical modelling".<br /><br />London Array, Walney 2 and Anholt actually use the conical TP method not "the fixed method" (this is the bolted flange method).<br /><br />All according to your link.Budgienoreply@blogger.comtag:blogger.com,1999:blog-32841798.post-87023732606735156312013-11-29T12:48:14.168+00:002013-11-29T12:48:14.168+00:00The grouting problem doesn't seem that serious...The grouting problem doesn't seem that serious for new offshore turbines, as it seems easily fixed with "Shear keys" - lumps of metal in the grout to take most of the load.<br /><br />Early offshore turbines didn't use this technique, they were bolted down. The grout was a cost & time saving method, and not including shear keys was a further cost saver.<br /><br />Apparently the use of Shear keys and grout is common in the oil rig industry for decades (although the direction of load characteristics is different so not exactly the same), so rather a bo-bo leaving the pins out on turbines - due to incorrect numerical modelling.<br /><br />London Array, Walney 2 and Anholt use the fixed method.<br /><br />Seemingly very good article about it:<br /><br /><a href="https://www.awordaboutwind.com/gambling-with-grout-worth-the-risk/" rel="nofollow">https://www.awordaboutwind.com/gambling-with-grout-worth-the-risk/</a><br /><br />But you're right ND, there could well be other future probs from the tough environment.rwendlandhttps://www.blogger.com/profile/07861901317813829419noreply@blogger.comtag:blogger.com,1999:blog-32841798.post-48436674681600829862013-11-29T12:30:40.735+00:002013-11-29T12:30:40.735+00:00Nick.
