LNG carrier

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.

LNG CARRIER Ben Franklin Port Revel

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.

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.
