- +30 % Greater Cargo capacity
20 to 30% less monthly fuel consumption
All the Bourbon Liberty have a Diesel-Electric Propulsion system.
This propulsion system reducing fuel consumption and CO2 reject by 20-30%.
Redundant propulsion equipments to optimize availability
Allows the full operation to continue with one generator out of service.
The Bourbon Liberty vessels are equipped with two azimuth and one fixed stern thrusters and two bow thrusters. These 5 thrusters are powered by 3 diesel generators.
The Diesel-Electric Propulsion and the redundancy of three generators and three thrusters ease maintenance of main system components and is also a safety factor.
Exceptional maneuverability to carry out operations safely with a more reliable vessel
The three stern thrusters (two azimuth thrusters and one fixed thruster) and the two bow thrusters allow exceptional manoeuvrability and station keeping capabilities.
Aditionally, this configuration permits the vessel to carry out operations safely and makes the vessel more reliable:
- These propellers combine propulsion power up to 5 000 KW (on Bourbon Liberty 200) and orientation on two thrusters, and thus enables conversion of the engine power directly into thrust with increased efficiency.
- The azimuth thrusters are capable of 360° rotation and allow utilization of full power during maneuvers and while station keeping using dynamic positioning.
The DP system is Class II certified which means redundancy on all equipment.
+30 % Greater Cargo capacity
The engines' position on the main deck increases the cargo space available in the hull of the Bourbon Liberty vessels. But they are not the only innovations on the cargo capacity. Indeed, The oval design of the tanks coupled with the faster and automated cleaning system, enables the loading to be optimized and the transfer operations speeded up.
In conclusion
- Maximum maneuverability,
- Optimal efficiency,
- Economical functioning,
- Space optimization
- Simplified maintenance
Testimony
DP2 System on Bourbon Liberty is excellent, it performs with highest position accuracy with minimum actuator activity.
