Abstract: The requirements for controlling emissions of the harmful substances in the atmosphere have become increasingly strong as the global marine environment is increasingly deteriorated with the gradual enhancement of environmental protection consciousness. The relevant environmental protection regulations on the ship emissions of IMO are continuously upgraded.This paper mainly focuses on the effective standard for NOX emission control and the standard for the SOX emission control to be coming into effect. The NOX and SOX emission control schemes that meet the requirements for the ocean exploration vessels are selected by the comparison of several emission reduction control measures that are commonly used in the current market. Finally, the NOX emission control equipment and the SOX emission control equipment are selected based on the equipment configuration of the ocean exploration vessels, in order to explore the design of the exhaust system and the reasonable arrangement of the related equipment.

Key words: ocean exploration vessel, NOX emission control, SOX emission control, selective catalytic reduction(SCR), seawater desulfurization, exhaust system

摘要： 随着全球海洋环境的日益恶化和环保意识的逐渐增强,控制大气有害排放的要求日益强烈,IMO不断升级船舶排放的相关环保法规。该文主要从已经生效的（NOX排放控制）及将要生效的规范（SOX排放控制）着手,通过目前市场上常用的几种减排控制措施对比,选择符合大洋勘探船的NOX和SOX排放控制方案,最后结合大洋勘探船设备配置选择NOX和SOX排放控制设备,从而展开对排气系统设计和相关设备合理布置的探索。
