Deniz Taşımacılığında Çevre Kirliliğini Önleyen Bir Ekolojik Liman Yükleme Bunkeri Tasarımı ve Analizi

Öz

Bu çalışma, küreselleşme sonucu limanlardaki dökme malzeme lojistiği ile ilişkili çevre kirliliğini ele almak amacıyla Türkiye'de geliştirilen 100 m³'lük “Ekolojik Liman Yükleme Bunker”ini analiz etmektedir. Ayrıca, malzeme israfını en aza indirgemek ve güvenli nakliye süreçlerini sağlamak da amaçlanmaktadır. Samsun limanındaki bunker ile ilgili hesaplamalar özetlenmekte, yapının yapısal sertliği ile ilgili sonlu elemanlar analizi ayrıntılı olarak ele alınmakta ve saha faaliyetleri çok sayıda mühendislik çalışmasıyla doğrulanmaktadır. Teorik hesaplamalar, bunkerin statik davranışını ve dinamik yüklere tepkisini değerlendirmek için FEM (Sonlu Elemanlar Yöntemi) analizleriyle desteklenmiştir. Bu, modal analiz yoluyla sistemin dinamik performansının değerlendirilmesinin yanı sıra, yapısal çerçeve içindeki çelik kolonlar ve kirişler için kombine tasarım, kesme ve sapma kontrollerini de içermektedir. Analiz, göreceli yük kombinasyonlarının maksimum değerlerinin sınır değerlerine oranının incelenmesini içermekte ve bu oranın tüm kolonlar ve kirişler için tutarlı bir şekilde 1'in altında olduğunu ortaya koymaktadır. Sonuçlar, geliştirilen ekolojik liman yükleme bunkerinin teorik olarak doğrulandığını ve sahada güvenli bir yapısal eleman olduğunu göstermektedir.

Building An Ecological Port Loading Bunker to Mitigate Environmental Pollution in Maritime Transport

Öz

This study analyses the 100 m³ ‘Ecological Port Loading Bunker,’ a novel development in Turkey with the objective of addressing environmental pollution associated with bulk material logistics in ports, exacerbated by globalization. It also seeks to minimize material waste and ensure safe transportation processes. The calculations pertaining to the bunker at Samsun port are outlined; finite element analyses concerning the structural rigidity of the construction are elaborated, and field activities are corroborated through multiple engineering studies. Theoretical calculations were supplemented by FEM (Finite Element Method) analyses to assess the static behavior of the bunker and its response to dynamic loads. This study included an evaluation of the system's dynamic performance through modal analysis, as well as combined design, shear, and deflection controls for the steel columns and beams within the structural frame. The analysis involved examining the ratio of the maximum values of the relative load combinations to the limit values, revealing that this ratio was consistently below 1 for all columns and beams. The results indicate that the developed ecological port loading bunker has been theoretically validated and is a safe structural element in the field.
