摘要
船型优化等绿色船舶技术在船舶营运阶段能效提升方面的应用研究广泛,但船舶建造阶段和拆解阶段的环境评价相关研究不足,因此难以从全生命周期角度评估绿色船舶技术在环境影响方面的贡献度。针对该问题,以15万吨级苏伊士型穿梭油轮为研究对象,对其因船型优化引起的全生命周期中的能源与物料差异进行试验测量与统计分析,然后基于生命周期评估(LCA)方法,使用SimaPro V9.6软件进行环境影响评价,分析船型优化对全球增温潜势(GWP)的影响和对碳减排的贡献度。结果表明:首先,船型优化技术在船舶制造阶段的碳减排贡献度要高于营运阶段,营运阶段高于拆解阶段,因此全面评价绿色船舶技术的碳减排效果不仅应考虑船舶营运阶段还应考虑船舶建造和拆解阶段。其次,就船型优化技术对营运阶段的碳减排效果而言,尽管LCA与船舶能效设计指标(EEDI)两种方法的结果显示出大体相同的趋势,但LCA结果比EEDI结果更保守,原因是两种方法在船舶实际工况设定条件上有些差异,并且LCA主流数据库中Ecoinvent-3中碳排放因子的定义对其燃料燃烧过程考虑不充分。
The application of green ship technologies,such as hull form optimization,has been widely studied for improving energy efficiency during ship operation.However,environmental evaluations of the shipbuilding and scrapping stages remain insufficient,making it difficult to assess the lifecycle environmental impacts of these technologies holistically.To address this gap,this study selects a 150,000-ton shuttle tanker as the research object.Experimental measurements and statistical analyses were conducted to quantify differences in energy and material consumption over the ship′s lifecycle resulting from hull form optimization.Using the Life Cycle Assessment(LCA)method implemented in SimaPro V9.6 software,an environmental impact assessment was performed to analyze the effects of hull form optimization on Global Warming Potential(GWP)and its contribution to carbon emission reduction.The results indicate firstly that the carbon reduction contribution of hull form optimization is highest in the shipbuilding stage,followed by the operation stage,and lowest in the scrapping stage.This suggests that a comprehensive evaluation of green ship technologies should account for not only the operational phase but also the construction and dismantling phases.Furthermore,while both LCA and the Energy Efficiency Design Index(EEDI)methods show broadly consistent trends in assessing the carbon reduction effect of hull form optimization during operation,the LCA results are more conservative.This discrepancy arises partly from differences in operational condition assumptions and the fact that the carbon emission factors in the Ecoinvent-3 database,commonly used in LCA,do not fully account for fuel combustion processes.
