Yeni Bir Bağlama Noktası Yerleşiminin Bağlama Planı Yük Dağılımına Etkisi

Abstract

ÖZET Limanlarda bağlı gemiler operasyonları süresince sabit tutulmaya çalışılmaktadır. Çevresel ve operasyonel yükler sebebiyle gemi üzerinde oluşan kuvvet ve momentler bağlama halatları ve usturmaçalarla sönümlenmeye çalışılmaktadır. Bu süreçte en aktif görev alan ekipmanların başında ise bağlama halatları gelmektedir. Bağlı gemileri limandan uzaklaştıracak yöndeki kuvvet ve momentler usturmaçaları geçersiz kılarak bu sönümleme işini bağlama halatlarına yıkmaktadır. Bu durumda halatlar üzerinde oluşacak yükün ve bu yükün dağılımının tespiti, halatların yük taşıma sınırlarının varlığı sebebiyle büyük bir önem kazanmaktadır. Çalışmamızda, denizcilik ekosisteminde yaygınlaşan daha büyük gemiler sebebiyle, bir bağlama limanına eklenecek yeni bir bağlama noktasının konum seçimi üzerine araştırmalar yapılmıştır. Seçilen VLCC sınıfı çok büyük ham petrol gemisinin kıç halatı bağlama noktası koordinatları değiştirilerek bağlama halatları üzerindeki etkisi incelenmiştir. Çalışma sonucunda mevcut bağlama planında çalışma kapasitesine %83,3 oranında ulaşmış kritik bir halat yükünün, aynı çevre koşullarında %73,3 seviyesine düşebileceği veya %94,0 seviyesine çıkabileceği keşfedilmiştir. Bu çıktı yeni bir bağlama noktası yerleşiminin, bağlama planı yük dağılımda önemli bir yeri olduğunu ortaya koymaktadır.

The Effect of a New Mooring Point Location Selection on the Mooring Plan Load Distribution

Abstract

ABSTRACT Ships moored in ports are tried to be kept stable throughout their operations. Forces and moments occurring on the ship due to environmental and operational loads are tried to be damped with mooring ropes and fenders. Mooring ropes are among the most active equipment in this process. The forces and moments that will move the moored ships away from the port render the fenders invalid and leave this damping job to the mooring ropes. In this case, determining the load that will occur on the ropes and the distribution of this load becomes of great importance due to the load carrying limits of the ropes. In our study, research was conducted on the location selection of a new mooring point to be added to a mooring port, due to larger ships becoming more common in the maritime ecosystem. The effect on the mooring ropes of the selected VLCC class very large crude oil ship was examined by changing the stern rope mooring point coordinates. As a result of the study, it was discovered that a critical rope load, which reached 83.3% of its working capacity in the current mooring plan, could decrease to 73.3% or increase to 94.0% under the same environmental conditions. This output reveals that a new mooring point placement has an important position in the mooring plan load distribution.
