摘要

航运在关注环保和经济高效的操作可以通过许多不同的措施来实现。其中大多数是技术方法,例如通过改变发动机控制参数,使用不同的燃料,废气处理系统或内部措施使发动机本身更高效或更环保。这些措施中缺失的部分是,仍然有人类负责控制船只,他们应该保持在效率的循环中。对于许多船舶来说,为了提高效率或减少排放而更换或加强现有的发电或推进系统既不高效,也不经济。一些内部措施甚至导致更高的燃料消耗,以减少氮氧化物的排放。因此,处理船舶的最佳操作程序,特别是发动机操作的结果,是环保船舶操作的重要来源。德国研究项目MEmBran(模拟船舶操纵期间的排放和燃料消耗)特别关注优化船舶发动机操纵的基础。它侧重于目前现有的船舶柴油发动机(在第一步4冲程发动机)的过程非常详细的模拟,以便将其应用于更全面的船舶处理模拟软件。作为现有的计划和预测软件的一部分,它可以在船上使用,使值班的航海人员和航运公司预测和比较每次操纵船舶的燃料消耗。它进一步允许识别船舶操作员在几种条件下可能采取的行动的最佳选择,然后将不同导航员的不同操作策略进行比较。

On-Board Support System for the eco-friendly ship operation in coastal and port areas
Shipping in concerns of eco-friendly and economical efficient operation can be achieved by many different measures. Most of them are technological approaches, e.g. by changing engine control parameters, usage of different fuels, exhaust gas-treatment systems or internal measures to make the engine itself more efficient or eco-friendly. The lost part in this measures is, that there are still humans who are in charge of controlling the vessel and that they should be kept in the loop of efficiency. For numerous vessels, it is neither efficient nor economically reasonable to exchange or enhance the existing power generation or propulsion systems in order to improve efficiency or reduce emissions. Some internal measures even lead to a higher fuel consumption in order to reduce NOx-emissions.Therefore optimal operational procedures for handling ships and specifically the outcome of engine manoeuvres is a substantial source for eco-friendly ship operations. The German research project MEmBran (Modelling Emissions and Fuel Consumption during Ship Manoeuvres) addresses especially the basis for optimising ship engine manoeuvres. It focusses on a very detailed simulation of the processes of currently existing ship diesel engines (in a first step 4-stroke engines) in order to apply them within a more comprehensive ship handling simulation software. As a part of an existing planning and prediction software that can be used on board, it enables the watchkeeping nautical officer and the shipping company to forecast and compare the fuel consumption of the ship for each manoeuvre. It further allows to identify the best option of the ship operator’s possible actions under several conditions and afterwards a comparison of varying manoeuvre strategies of different navigators will be enabled.
