A级科目二MARPOL重点题目

一、单选题(共120题,每题0.5分,共60分)



1、2024 年 7 月,某注册验船师在对一艘总吨位为 499GT、建造于 2015 年的国际航行散货船执行年度检验。在核查其机舱油污水标准排放接头时,该验船师发现船上配备的法兰样品尺寸存在差异。根据 MARPOL 附则 I 的强制性要求,下列关于油类排放接头法兰外径的描述,正确的是:



A. 法兰外径可根据船舶总吨位调整,499GT 船舶允许采用 200mm 外径的法兰



B. 法兰外径应采用公约规定的标准尺寸 215mm,不得随意变更



C. 法兰外径应与螺栓圈直径一致,采用 183mm 外径



D. 法兰外径无强制性标准,只要能承受 600kPa 工作压力即可



答案:B

解析:

根据《MARPOL 73/78》 附则 I第 13 条 “标准排放接头” 的明确规定,油类排放接头法兰的外径标准尺寸为 215mm,该尺寸为强制性统一标准,与船舶吨位、航区无关。



2、In March 2024, a marine surveyor carried out a renewal survey on an oil product tanker of 12,000 GT engaged in international voyages, which was delivered in August 2010. During the verification of the bolt configuration for the oil discharge connection flange, the surveyor shall confirm whether the number and size of bolts comply with the mandatory requirements of MARPOL Annex I. Which of the following configurations fully meets the requirements of the Convention?



A. Fitted with 4 bolts of 18 mm diameter and matching nuts, with length adjusted according to flange thickness



B. Fitted with 6 bolts of 20 mm diameter and matching nuts, of appropriate length to satisfy the installation requirements of the flange and gasket



C. Fitted with 8 bolts of 16 mm diameter and matching nuts to improve the connection strength of the flange



D. Fitted with 6 bolts of 22 mm diameter and matching nuts, consistent with the diameter of the bolt holes



答案:B

解析:

《MARPOL 73/78 附则 I》第 13 条明确规定:“螺栓和螺帽:数量、直径:6 个,每个直径 20 mm,长度适当。”





二、多选题(共30题,每题1分,共30分)



1、In February 2024, a marine surveyor conducted an intermediate survey on a container ship built in 2020 and engaged in international voyages. When verifying the technical requirements for the oil discharge connection flange, which of the following descriptions regarding flange material, pressure resistance and compatibility meet the requirements of the Notes to MARPOL Annex I?



A. The maximum internal diameter of pipeline acceptable for the flange is 125 mm, i.e. all oily water discharge pipelines with an internal diameter not exceeding 125 mm are compatible with this standard flange.



B. The flange shall be constructed of steel or other equivalent material in terms of strength and toughness, with a smooth and defectfree surface.



C. When used together with a gasket made of oiltight material, the assembly shall be capable of withstanding a working pressure of 600 kPa without leakage.



D. The internal diameter of the flange may be adjusted according to the actual external diameter of the onboard pipeline, and no fixed dimension is required.



答案:ABCD

解析:

根据《MARPOL 73/78 附则 I》第 13 条:

“法兰应设计为能接受最大内径为 125 mm 的管路,以钢或其他同等材料制成,表面平整。这种法兰,连同一个油密材料的垫圈,应能承受 600 kPa 的工作压力。”



2、2024 年 6 月,某注册验船师在对一艘国际航行油船执行防污设备检验。在核查油类排放接头法兰的标准尺寸时,下列选项中,符合 MARPOL 附则 I 第 13 条规定的有:



A. 法兰螺栓圈直径为 183mm



B. 法兰厚度为 20mm



C. 法兰外径为 215mm



D. 法兰槽口的螺栓孔直径为 20mm



答案:ABC

解析:

根据《MARPOL 73/78》 附则 I第 13 条“标准排放接头”对法兰尺寸的规定如下:

外径:215 mm;

螺栓圈直径:183 mm;

法兰槽口:直径为22 mm 的孔 6 个;

法兰厚度:20 mm。
