Innovation and Polyvalence

Designed by Guido Perla and Associates, and tailored to BOURBON specifications, these vessels reap the benefit of BOURBON's long experience in deepwater offshore and are a real “revolution” on the continental offshore market.

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%.

For example, the Bourbon Liberty 100 consumes nearly 165 tons LESS fuel per month than traditional offshore support vessel of equivalent power (see the graph).

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.

With The DP II system, the Bourbon Liberty is able to maintain precise position and come safely alongside rigs or platforms to offload cargo or for anchor handling operations.

+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.

The Bourbon Liberty series gains 30% cargo capacity compared to traditional vessels.

In conclusion

The Bourbon Liberty Series in 5 major assets of this simple and reliable concept.
  • 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.
