JENERİK BİR SAVAŞ GEMİSİNDE GEMİ-YAŞAM DÖNGÜSÜ DEĞERLENDİRMESİ (SLCA) VE MALİYET MODELİ (SLCC) GELİŞTİRİLMESİ

Abstract

Savaş gemileri, uluslararası anlaşmalar tarafından belirlenen pek çok kural ve yönetmeliklerden muaf tutulduğundan, bu gemilerin atık ve emisyon yönünden yaşam döngüsü analizi üzerine çok az çalışma vardır. Bu çalışmanın amacı, jenerik bir savaş gemisinin iki bileşeninin çevresel etkilerini ve maliyet analizini hesaplamak ve Yaşam Döngüsü Değerlendirmesi'ni (LCA) kullanarak emisyon azaltımını araştırmaktır. Jenerik bir savaş gemisinin valf ve yağlama yağı sistemleri atıkları, valf ve yağlama yağının tüm kullanım ömrü, nakliye ve geri dönüşüm aşamaları da dahil olmak üzere lisanslı SimaPro yazılımı kullanılarak hesaplanmıştır. Ayrıca, LCA yöntemi kullanılarak elde edilen faydaları hesaplamak için Yaşam Döngüsü Maliyet analizi (LCC) uygulanmıştır ve geri dönüşüm işlemiyle elde edilen toplam faydaların yaklaşık 46.400 € olduğu sonucuna ulaşılmıştır. Atık valf ve yağlama yağının çevresel etkileri hesaplanarak, atık yağın geri dönüşümünün gemi başına atık yağ ayrıştırma maliyetini %30 oranında azalttığını göstermektedir.

GENERIC NAVAL VESSEL WASTE MANAGEMENT MODEL DEVELOPMENT IN SHIP-LIFE CYCLE ASSESSMENT (SLCA) AND COST (SLCC)

Abstract

Naval vessels are exposed to many of the rules and regulations determined by international treaties, there are few studies on life cycle analysis of these ships. The aim of study is to calculate life cycle impacts and cost analysis of two vital parts of a generic warship and investigate the emission reduction by using Life Cycle Assessment (LCA). Two important parts (valve and lubricating oil) of a generic warship are selected and the wastes and emissions of these parts are calculated by using licensed SimaPro software. The whole life cycle of the valve and lubricating oil is considered including transportation and recycling phases. Besides, Life Cycle Cost (LCC) analysis is implemented to the samples to calculate the benefits obtained by using LCA method. LCC is implemented on the system and its resulting total benefits, which is obtained by recycling process, is approximately 46,400 €. The environmental impacts of waste valve and lubricating oil are calculated by the help of licensed SimaPro software. The results show that recycling waste oil recovers the cost of waste oil separator by 30 % per ship.
