LNG Carrier
The "Ben Franklin" model
The "Ben Franklin" is a replica of the liquid natural gas (LNG) carrier (125 000 m3), fitted with Controllable Pitch Propeller and Schilling rudder if requested.
The CPP on this model is a left-hand turning propeller when sailing ahead.
However, it behaves like a right handed propeller when sailing astern.
This is because the propeller is left-hand turning at any time, as it is the blades that change pitch instead of the propeller shaft going reverse.
As an option, this model can also sail with a traditional fixed pitch as a left-handed propeller.
Another option on this ship is a Schilling rudder which has fish-tail shape and a maximum rudder angle of 70°. With this angle, the Schilling rudder has a 77% propeller disk coverage instead of 52.5% for a conventional rudder with 35° max rudder angle.
This induces:
- Significantly reduced overshoot angles.
- Exceptional full speed course keeping ability.
- Improved crabbing and zero speed control.
- Enhanced turning capability with significantly reduced turning circles at speed.
- Reduced head reach and lateral deviation.
The Q-Max model
In this version, the Q-Max can carry 266 000 m3 of LNG and has twin-screw inward turning propellers and two rudders.
The length o.a is 345 m and breadth is 53,80 m. The max windage is 9000 square meters.
