: 1 hour per student per week.

: Term Work                       : 200 Marks

: Oral                       : 100 Marks

: To acquaint the student with overall functioning of a ship, exposure to the Ship’s Organization Structure, various direct / indirect activities and procedures associated with the operation of the ship. On completion of the training, the trainee will be competent to keep independent watch of all the machinery of the engine room.

: Hands on experience in tackling real operational situations, and investigative assignments. The approach is to complete the task of each competence under the four functions of the engine room of a ship.

An investigative and analytical approach looking at a problem in its entirety and not in isolation. The project report should contain problem definition and objective, background information, possible approaches and approach selected, data identification, analysis or investigation carried out , results and discussions and jobs done. Specific study stressing clarity, brevity and simplicity of styles. Safety and Risk analysis will from intrinsic part of the report.
