Not too long ago chronometers were the only instrument used on board ships for accurate timekeeping for purpose of navigational calculation. Some older ships used to carry two chronometers as a safeguard against mechanical failure or accident. but even chronometers have not escaped the advancement of science and the older

As with other ships, tankers are high in the water (they have a large freeboard) when empty. Due to this the bow tends to bounce along the waves instead of slicing through them. This causes heavy stresses and also decreases the stability of the ship. Ballast is taken to increase

Prior to discharging dirty ballast, it's necessary to relinquish time for the ballast to settle to induce a decent oil/water separation. It is a legendary reality - oil is lighter than water and would perpetually float on prime of water - provided enough time is given for it to settle. The time for subsidence might vary betting on the movement of the ship and also the variety of oil being handled - this sometimes depends

It must be remembered that a ship is a floating object and to calculate its displacement, it is necessary to calculate its underwater volume when multiplied by the density of the water in which the ship floating. For the purpose of standardization, the density of fresh water is taken as 1.000
