Hi guys
I found this
BT Marine has supplied Triple Rudder & Nozzle system to MacDuff Shipyards Ltd.
Further to the success of the fishing Trawler “Resilient’s” installation of High Trust nozzle and Triple rudder system, BT Marine has recently supplied a further assembly to the fishing Trawler “Amity” installed by MacDuff Shipyards Ltd on her recent re-fit.
The Resilient is fitted with a CPP system for main propulsion, where as the Amity Is using a 1900mm diameter 4 blade FPP system also supplied by BT Marine. The system has seen marked improvements in the steering and manoeuvring characteristics of the vessels, along with a fuel saving, greater bollard pull and all round better engine performance.
The rudder system designed, manufactured and assembled fully by BT Marine, and utilises 3 independent rudder blades, all connected through a complex linkage system, allowing the outer blades on full lock to travel further, giving greater manoeuvrability under a heavy sea or Trawl.
With the focus on efficiency and fuel economy being more and more pushed to the forefront of design, BT Marine has looked at all parts of the propulsion & Steering systems and has just signed a contract for a High Efficient Flap style rudder 2.8m blade size for delivery to Russia, to RMRS Classification.
