Der Austausch von Navigationsbojen gegen eisfeste Alternativen vor der Eissaison ist nicht nur empfehlenswert, sondern unerl\u00e4sslich.<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Warum ist dieses Thema so dringlich?<\/h2>\n\n\n\n<p>Jedes Jahr verursacht das Meereis Sch\u00e4den in Millionenh\u00f6he an der Meeresinfrastruktur. Stellen Sie sich eine Standard-Navigationsboje vor, die mit einem 4-5 Tonnen schweren Betonanker verankert ist - das klingt sicher, oder? Nicht, wenn sie mit massiven Eisschollen konfrontiert ist, die treiben. Die schiere <strong>Der Schub des Meereises kann Ankerketten zerrei\u00dfen<\/strong> und Bojen weit vom Kurs abdr\u00e4ngen. Wenn dies in einer stark befahrenen Schifffahrtsstra\u00dfe geschieht, kann es zu Schiffssch\u00e4den oder sogar zu Unf\u00e4llen kommen.<\/p>\n\n\n\n<p><strong>Das ist ein echtes Problem:<\/strong> Wenn das Meerwasser auf -1,5 \u00b0C f\u00e4llt, kann sich das Meereis dramatisch ausdehnen. Ein 1.000 Meter breites Eisfeld kann allein durch die Gefrierausdehnung um 0,45 Meter wachsen - mehr als genug, um eine Standardboje zu zerdr\u00fccken oder zu \u00fcberfluten. Aus diesem Grund empfiehlt Sunhelm, herk\u00f6mmliche Bojen durch speziell entwickelte Bojen zu ersetzen. <strong>Eisbojen<\/strong> bevor der Winter eintrifft.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"780\" height=\"850\" src=\"https:\/\/www.sunhelmmarine.com\/wp-content\/uploads\/2021\/09\/marine-buoys.jpg\" alt=\"navigation buoys\" class=\"wp-image-665\" srcset=\"https:\/\/www.sunhelmmarine.com\/wp-content\/uploads\/2021\/09\/marine-buoys.jpg 780w, https:\/\/www.sunhelmmarine.com\/wp-content\/uploads\/2021\/09\/marine-buoys-275x300.jpg 275w, https:\/\/www.sunhelmmarine.com\/wp-content\/uploads\/2021\/09\/marine-buoys-768x837.jpg 768w, https:\/\/www.sunhelmmarine.com\/wp-content\/uploads\/2021\/09\/marine-buoys-134x146.jpg 134w, https:\/\/www.sunhelmmarine.com\/wp-content\/uploads\/2021\/09\/marine-buoys-46x50.jpg 46w, https:\/\/www.sunhelmmarine.com\/wp-content\/uploads\/2021\/09\/marine-buoys-69x75.jpg 69w\" sizes=\"auto, (max-width:767px) 480px, (max-width:780px) 100vw, 780px\" \/><\/figure><\/div>\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Was passiert mit regul\u00e4ren Navigationstonnen im Winter?<\/h2>\n\n\n\n<p><strong>Meereis ist nicht nur kalt - es ist m\u00e4chtig.<\/strong> Konventionelle Bojen k\u00f6nnen sein:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Durch Druck gequetscht<\/strong>: Wenn das Eis um eine Boje herum gefriert, dehnt es sich aus und kann die H\u00fclle aufbrechen, so dass Wasser eindringt.<\/li>\n\n\n\n<li><strong>Aus der Verankerung gerissen<\/strong>: Selbst schwere Senkblei k\u00f6nnen ihre Position nicht halten, wenn die Eisschilde mit ungeheurer Kraft schieben.<\/li>\n\n\n\n<li><strong>Physisch zerst\u00f6rt<\/strong>: Eisbewegungen k\u00f6nnen Bojenk\u00f6rper verformen, Solarpaneele oder Beleuchtungen besch\u00e4digen oder die gesamte Konstruktion versenken.<\/li>\n<\/ul>\n\n\n\n<p>Deshalb ist es in eisigen Gew\u00e4ssern keine Option, die Sommerbojen einfach \u00fcber den Winter an Ort und Stelle zu lassen. <strong>Herk\u00f6mmliche Navigationsbojen halten dem Druck des winterlichen Meereises nicht stand.

Diese Form <strong>reduziert den Druck<\/strong> die vom Meereis ausge\u00fcbt wird. Wenn Treibeis auftrifft, wird es durch die konische Form gespalten und bildet eine schmale eisfreie Spur hinter der Boje. Es ist fast so, als w\u00e4re die Boje <strong>durch das Eis \"segeln\"<\/strong>und hinterl\u00e4sst ruhiges Wasser.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. <strong>Die F\u00e4higkeit, sich unter Eis zu \"verstecken<\/strong><\/h3>\n\n\n\n<p>Wenn schwere Eisschollen eindringen oder die Oberfl\u00e4che vollst\u00e4ndig gefriert, kann die Boje dank ihrer Struktur <strong>leicht unter das Eis eintauchen<\/strong> anstatt ihm frontal zu begegnen. Sobald sich das Eis zur\u00fcckzieht, taucht die Boje mit <strong>minimaler Schaden<\/strong>. Die robuste Platte h\u00e4lt Druck und Feuchtigkeit stand, ohne zu brechen oder undicht zu werden.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Warum Sunhelms Meeresbojen w\u00e4hlen?<\/h2>\n\n\n\n<p>Unter <strong>Sonnenhelm<\/strong>Wir liefern nicht nur Bojen, wir entwickeln sie auch f\u00fcr die h\u00e4rtesten Meeresbedingungen.
