6. SHIP'S LIST ANGLE. DRAUGHT IN OPPOSITE SIDE. |
||||||
| It is very important to know the list angle of the vessel because later on it is possible to calculate also draights in opposite side to the moored side of your vessel.In fact, with sea force 5 or more, it is impossible to read draughts by using pilot ladder. Softwares n. 6 and n. 6A use two different methods to calculate draughts at sea side when your vessel is moored. The first method uses the observed ullage in one of many ship's compartment having liquid cargo or water. The second, uses the breadth of the vessel. It is well known that inclinometer placed in the bridge,is not helpful in this case. This program is very useful to calculate the ship's displacement with draught survey. | ||||||
| THE FOLLOWING DATA INPUTS ARE REQUESTED: | ||||||
| PRACTICAL EXAMPLE: | ||||||
| Angolo di sbandamento pescaggi lato opposto |
||||||
| DATA INPUT | ||||||
| TRIM of the vessel | 7.00 m. | |||||
 |
Distance between ship's perpendiculars | 160.00 m. | ||||
| Tank's observed ullage | 16.50 m. | |||||
| Tank's observed sounding | 0.11 m. | |||||
| Tank's Height from measurement point | 16.40 m. | |||||
| Breadth of the vessel | 24.00 m. | |||||
| Amid draught(moored side of the vessel) | 9.10 m. | |||||
| DATA OUT | ||||||
| List angle in degrees | 8.78 gradi | |||||
| Amid draught opposite to moored side | 12.807 m. | |||||
|
12 metres.
|
||||||
|
80.7 centimetres.
|
||||||
| If there is impossible to have on board a compartment with liquids inside, you can use the program n. 6A which calculates draughts by using the breadth of the vessel. | ||||||
