Scrubber technology and modelling assumptions

This study assumes usage of wet scrubber systems to reduce SOx emissions by scrubbing the exhaust gas from the engines with seawater. After the turbocharger, the exhaust is led into a large scrubber placed in the exhaust stack of the ship, downstream from the exhaust gas boiler. The exhaust is led through an array of seawater droplets which washes the sulphur out of the exhaust gas. The washwater is collected, purified and discharged into the sea.

Scrubbers are assumed to be used only when needed to meet the emissions values corresponding to the low sulphur fuel limits, i.e. inside ECA, in EU ports and globally by 2020. Their operating costs depend on operation time and engine loads.

An average cost for open and closed loop scrubbers of 5 $/ MWh was used. Lost TEU slots depend on the space required for the scrubber installation. Up to 0.3% of the total available TEU slots are assumed to be lost. This is assumed to apply only every second voyage. Other operation costs such as crew spare parts and maintenance are assumed to be 20% higher than the reference vessels.

洗涤技术和模型假设

这项研究假设：湿式洗涤器能通过消除发动机排放的尾气来减少SOx的排放。废气通

过涡轮增压器进入船只排气烟囱中的大型洗涤器中，沿废气锅炉顺流而下。废气经过一串水珠，将硫磺洗去。将洗涤水收集、净化，并排放到海里。

通常认为（如，到2020年，非洲经济委员会内部，欧洲港口及全球的）排放值只有在满足最低硫燃料时才使用洗涤器。他们的运行成本取决于运行时间和发动机负荷。

使用平均成本为5美元/兆瓦·小时的开环和闭环洗涤器。浪费的标准箱槽取决于洗涤器安装所需的空间。假设最多浪费0.3%的标准箱槽，这一假设只用于二次航行。其他的运行成本，如船只零用配件和维护，比参考船只高20%。
