TEST FACILITIES FOR THE VALUATION OF COMPLEX MARITIME STRUCTURES
Objectives :
BGO FIRST is a multipurpose basin mainly dedicated to maritime structures studies used in offshore oil industry and coastal engineering. These studies based on reduced scale model tests allow the determination of these structures behavior facing complex marine environment and their performances assessment.
Characteristics :
- Basin dimensions:
| Length : |
40 m |
| Width : |
16m |
| Depth of water : |
0 to 5 m |
| Central well : |
10 m of depth, 5 m of diameter |
- Waves generation :
| Type : Regular or irregular (PM, Jonswap
|
, Ochi-Hubble, Gaussian, White noise …) |
| Maximum height : |
0.8 m |
| Periods : |
0.6 s à 4 s |
- Current generation :
| Direction : wave propagation or opposite |
|
| Max velocity : Function of the water dept |
h (up to 1.2m/s for a depth of 1m) |
- Wind generation :
| Maximum speed : |
5 m/s |
| Direction : |
0 to 360 deg |
- Movable floor :
| Depth : |
0 to 5 m |
| Inclination : |
+/- 4 deg |
- Motorized tests bridge :
| Longitudinal speed : |
1.2m/s |
| Transversal speed : |
0.8m/s |
| This bridge allows to impose to models de |
fined trajectory thank to its close loop control |
- Other equipments :
| Current velocity increase by means of a convergent |
| 6DDL motion generator |
| Dynamic Positioning system |
Advantages :
- Compact shape of the basin allowing to carry out tests accurately, quickly and with flexibility.
- Simultaneous generation of the waves, current and the wind.
- Possibility of performing tests in shallow or deep water.
- Computer equipment and modern measurement tools.
- Specialized knowledge in experimental hydrodynamics supplemented by university researchers competences
Applications :
- Oil offshore engineering
- Coastal engineering
- Naval egineering (low speed ships or fixed point floating structures)
