CRUDE OILS (Mineral)
- Description: With regard to the minimizing of damage, the most important factor is to keep the damaged oil separate from the sound. In most cases, only certain ship's tanks are affected if it is a question of contamination. When there is water in the cargo, this is generally at the bottom of the ship's tanks. If possible, damaged cargo should be pumped to separate shore tanks where it can be treated, water allowed to settle out, or at least prevented from contaminating the whole of the cargo. A frequent cause of incorrect claims is an attempt to sample mixtures of oils and free water. This is a very difficult procedure and the best method is to draw off all free water before attempting to sample, which should be done after the water has had time to settle out, otherwise a false result is almost bound to follow. Alternatively, gaugers can establish the lever where water resides, by use of sensors or color cut paste. At most discharge ports suitable arrangements can be made by allocating small shore tanks or even tank barges for the damaged portion. See also BULK OILS and FATS.
