*AUXLINES
Data format :
A single line with one value followed by an arbitrary number of lines with 4 values each :
IRIS
DI_1 DET_1 RHO_1 PINJ_1
...
DI_i DET_i RHO_i PINJ_i
Status:
Optional
Purpose:
To define auxiliary lines (K&C, booster, hydraulic, buoyancy) related to a riser group
Details :
| Parameter | Description |
|---|---|
| IRIS_i | Identification number of the set of elements defining a rigid riser |
| DI_i | Internal diameter of the auxiliary line [m] |
| DET_i | Water tightness diameter of the auxiliary line [m] |
| RHO _i | Internal fluid specific gravity of the auxiliary line [1] |
| PINJ_i | Injection pressure in the auxiliary line [N/m2] |
Restrictions:
The selected riser group IRIS must have been previously defined.
Note
The auxiliary lines are riser dependant. Consequently, they must be defined for each riser group (*RISER). Hence, we can have several time *AUXLINES in an input file.
Example :
*AUXLINES 3 0.1143 0.1524 1.32 1E5 0.09525 0.1143 1.32 2.89E7 0.05398 0.06985 1.025 3.45E7
3 auxiliary lines are defined, related to the riser group number 3
