The cable will be protected with a rock armour layer. TenneT has asked Sva\u0161ek Hydraulics to determine a suitable rock grade for the protection of this cable at four locations with different prevailing wave and current conditions.\r\n\r\nThe hydraulic conditions for these four locations are very different: in open sea, in the tidal channel or at a tidal flat. Depending on its location, wave conditions, current conditions or a combination of both determine the design conditions.\r\n\r\nCharacteristic wave and current conditions were derived from long term simulations with a <a href=\"https:\/\/www.svasek.nl\/model-onderzoek\/swan\/\">SWAN<\/a> wave model and a <a href=\"https:\/\/www.svasek.nl\/model-onderzoek\/finel\/\">FINEL<\/a> hydraulic model for currents.\r\n\r\nFor all locations an innovative approach was applied. This approach is based on the bed shear stress which is resulting from wave and currents forces. The rock size is deducted from the bed shear stress. It offers the possibility to combine wave forces and current forces in a sophisticated way.\r\n\r\nTo improve the reliability of the calculated rock size several sensitivity analyses were performed. For instance the rock size corresponding with 1 in 50 years  hydraulic conditions were compared with rock sizes corresponding to 1 in 100 years.\r\n\r\nAccording to this assessment rock sizes were only marginally higher for the 1 in 100 year conditions, so the safety margin for the rock size could be chosen less conservative. This could potentially reduce the costumer\u2019s costs significantly."},"slider":[{"image":1849,"video":""},{"image":1845,"video":""},{"image":1847,"video":""}],"expert_guy":{"left":{"title":"More information?","content":"Please contact Anna Kroon.","linkedin_link":"https:\/\/www.linkedin.com\/in\/anna-kroon\/","email":"kroon@svasek.nl"},"right":{"title":"Anna Kroon","designation":"Project leader","photo":892}},"cta":{"title":"MORE INFORMATION ABOUT SVA\u0160EK OR OUR EXPERTISES?","text":"Please contact us or make an appointment.","link":{"title":"CONTACT US","url":"https:\/\/www.svasek.nl\/en\/contact\/","target":""}},"custom_links":{"linked_url":""},"hide":[]},"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/project\/1850","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/project"}],"about":[{"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/types\/project"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/media\/1849"}],"wp:attachment":[{"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/media?parent=1850"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/tags?post=1850"},{"taxonomy":"project_category","embeddable":true,"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/project_category?post=1850"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
