【摘要】：国际金融危机爆发后,航运市场持续低迷,航运企业开始面临较大的压力和挑战,不仅需要应对市场价格持续走低的压力,同时还要处理运营成本高等问题。同时,航运业追求经济效益最大化,其前提是船舶必需满足IMO规范标准、MARPOL国际公约以减少污染、保护环境,这对船舶节能减排的要求越来越高。为了摆脱航运经营困境,航运公司应通过各种方式来降低运营成本。同时,随着炼油技术提高,冶炼出超低价的重质燃油,重质燃油沥青质含量越来越高,油品粘度越来越大,燃油中大分子成分越来越多,代表油质状态的燃油型号也越来越大,而航运公司为了进一步降低船舶营运成本中燃料油的使用成本份额,将降本增效策略进一步延伸到船舶燃用高粘度燃油,以实现营运成本的再降低。实践和理论证明,船舶低速航行及燃烧高粘度燃油是一项非常有效的节能减排措施,同时也产生了不容忽视的负面影响,诸如影响主机寿命,增加船舶备件消耗和维修保养强度,甚至影响航行安全性。目前,真正实施"主机超低速及燃烧高粘度燃油的国内外航运公司凤毛麟角,可供吸取的经验和教训更是缺乏。本文通过对大型万箱级集装箱船舶实施主机低速及燃烧高粘度燃油运行的实践研究,分析船舶在降速及燃用高粘度燃油过程中影响船舶经济性、安全稳定性因素,并通过对影响因素的分析论证得出行之有效的规避和解决对策。论文是依托中远集团"船舶降速及燃烧高粘度燃油风险控制研究"课题(N0.2013-1-R-COO1)完成,本人作为该课题主要参与研究人员。论文可作为指导航运企业船舶降速及燃烧高粘度燃油最佳实践,指导新造船舶的节能减排设计,同时也适用于航运公司的营运策略、技术策略和管理策略,对航运公司船队综合节能减排策略的最佳实践具有参考价值,对应对航运市场低迷,推广船舶降速及燃烧高粘度燃油的经验成果具有极高的实用性。
[Abstract]:After the outbreak of the international financial crisis, the shipping market continued to be depressed, shipping companies began to face greater pressure and challenges, not only to deal with the pressure of market prices continue to decline, but also to deal with the high operating costs and other issues. At the same time, the shipping industry pursues the maximization of economic benefits, the premise of which is that ships must meet the IMO standard and MARPOL international convention in order to reduce pollution and protect the environment, which demands more and more energy saving and emission reduction for ships. In order to get rid of the predicament of shipping operation, shipping companies should reduce their operating costs in various ways. At the same time, with the improvement of refining technology, ultra-low price heavy fuel oil has been refined. The asphaltene content of heavy fuel oil is getting higher and higher, the viscosity of the oil product is becoming larger and larger, the macromolecular composition of the fuel oil is increasing, and the fuel type representing the oil quality state is also becoming larger and larger. In order to further reduce the cost share of fuel oil in ship operating cost, the strategy of reducing cost and increasing efficiency is further extended to the use of high viscosity fuel to achieve further reduction of operating cost. Practice and theory prove that low speed navigation and combustion of high viscosity fuel are a very effective energy saving and emission reduction measure, but also have negative effects, such as affecting the life of the main engine. Increase ship spare parts consumption and maintenance strength, and even affect navigation safety. At present, there are very few domestic and foreign shipping companies that really implement the "super low speed engine and high viscosity fuel burning", and the experience and lessons to be learned are even less. Based on the practical research on the low speed engine and high viscosity fuel operation of the large ten thousand container ship, this paper analyzes the factors that affect the economy, safety and stability of the ship in the process of reducing the speed and burning the high viscosity fuel. And through the analysis and demonstration of the influencing factors, the effective evading and solving countermeasures are obtained. The thesis is based on COSCO Group's "Research on the risk Control of ship deceleration and Combustion High viscosity fuel" (N0.2013-1-R-COO1). I am the main participant in this project. The paper can be used as the best practice of ship speed reduction and high viscosity fuel burning in shipping enterprises and the design of energy saving and emission reduction for newly built ships. It is also applicable to shipping companies' operation strategy, technical strategy and management strategy. It has reference value for the best practice of comprehensive energy-saving and emission reduction strategy of shipping company fleet, and has high practicability for dealing with the downturn of shipping market and popularizing the empirical results of ship's deceleration and burning of high viscosity fuel.
