As we know, register is one of the important factors affecting the uses of tense and aspect in a text. Thisthesis concentrates on the characteristics of tense and aspect in Marine Engineering English (MEE). This research is basedon the six corpora:MEE,NEC,T4,MTE,BROWNA and LOBA. The first two parts in this paper introduce some theo-ries and features on tense and aspect in English. The following part gives a detailed comparison and analysis of the data ob-tained through the software SNOBOL4 and SPSS. Finally it is concluded that MEE is significantly different from the othercorpora in the distribution of tense and aspect. MEE uses mainly the present tense as far as tense is concerned and usesmore perfective aspects as far as aspect is concerned.
