Assignments at Sea

Shipboard Assignments:

++ These are meant for those of you at sea doing steam-time now!

++ You need to complete six assignments at sea.

++ Either do six assignments from the suggested list below -- one from each topic -- or you may suggest your own assignments (in that case you need to check with me first...just send me a mail at Kalyan@sp.edu.sg ).

++ Table below lists the suggested assignments. Please note the submission should be based on your shipboard plant and NOT reproduction of information from books.

++ Don't forget that once you finish your sailing time, you need to seat for a 3-hour written examination at SMA and an oral examination at the MPA (both at 1st Class level)!
