Cleaning ships cargo holds is difficult! Especially when you are loaded first with dirty cargoes and then you will shift to loding of clean cargoes like rice, fertilizer and grains. Usually it takes us, 3 to 4 days to clean all the holds but sometimes we are rushing it and finishing it for 2 days. At that state, we are already exhausted and we lack sleep and rest but for additional pay, we still finish it. By the way our ship has 5 cargo holds. 5 holds are very hard to clean,how about 7 and 9 holds? By just thinking, it already makes me tired. Thanks for reading guys.
