English of Marine Engineering: Characteristics of Phrases and Idioms

This study explores the unique characteristics of Marine Engineering English, a specialized form of English for Specific Purposes (ESP) used in ship machinery operations. Focusing on technical terminology, idiomatic expressions, and their functional roles, the research aims to identify how Marine Engineering English facilitates clear and efficient communication in marine engineering contexts. Data were collected from marine engineering textbooks, international journals, and authentic communication transcripts, and analyzed using thematic analysis. The findings reveal that Marine Engineering English is characterized by its technical precision, standardized terminology, and use of idioms rooted in maritime traditions. Phrases like "main engine overhaul" and idioms such as "running like a well-oiled machine" are essential for operational safety and teamwork. Compared to General English, Marine Engineering English is highly specialized, with a focus on operational efficiency and cultural identity. The study concludes that integrating technical vocabulary and idiomatic expressions into maritime education can enhance learners' communicative competence. Practical recommendations are provided for learners, educators, and industry professionals to improve the teaching and application of Marine Engineering English.
