18. CLINGAGE

This program replaces a compulsory complex formula used to obtain a corrected calculation to find the CLINGAGE; This formula is suggested by IMO.

The "CLINGAGE" is the cargo volume remained well stiked in the internal structures of a cargo tank. It is obvious that this is more to be considered in the vessel cannot effect CRUDE OIL WASHING OPERATIONS. It is well known that CRUDE OIL WASHING is very important to carry out, because it is possible to eliminate 98% of cargo sediments in tanker vessels and this is the way to cut down the quantity of SLOPS in the cases of cargo tanks cleaning up. The calculated volume , i.e. the CLINGAGE, therefore remains on board and cargo receivers can have the right to detract it from the quantity declared in the Bill of Lading or from the quantity of cargo delivered, together with the R.O.B. (i.e. the cargo remained in the bottom of cargo tanks).

The CLINGAGE is to be calculated in all cargo tanks when it is impossible to carry out a CRUDE OIL WASHING. Remember that in the cargo volume delivered ashore, is also to be considered the volume of O.B.Q. (ON BOARD QUANTITY) i.e. the cargo volume ascertained in the bottom of cargo tanks prior to commencing loading operations. Preliminarly this program is supplied with a calculation to be used only for an example and only the RETURN KEY or PAG.UP/PAG. DOWN KEYS of your keyboard are to be used; but you can replace all data with new data to carry out a new calculation. When you switch off your computer and then switch ON itself, the last calculation effected will appear and you can do very quickly a new calculation.
