The development trend of Marine engineering had different time, at different times have different research focus, from the patent literature level on the trend of development of ocean engineering is analyzed, the build is based on the analysis of the patent literature and ocean engineering development situation, the research to the development of ocean engineering technology in the field is of great significance. In order to solve the existing literature and patent analysis based Marine engineering development trend research of ocean engineering function equation based on patent analysis based on map and patent literature analysis method is discussed on the basis of the analyses based on the literature and patents of ocean engineering development trend research of search keywords and data source has carried on the simple introduction. And based on the existing literature and ocean engineering development trend of patent analysis model of workflow design is discussed, finally the existing based on the analysis of ocean engineering and patent application development situation of experimental analysis, the experimental data show that the number of patent for academic and research in ocean engineering from 1987 to 2007 before the slow growth, However, the number of patents showed a significant growth trend from 2007 to 2017, and reached 150 after 2020. Therefore, the research on the development situation of ocean engineering based on literature and patent analysis has certain reference significance.
