Twin Fin Propulsion

We deliver low consuming, price winning propulsion design for the toughest demands bringing safety into the arctic.

TWIN FIN CONVENTIONAL WITH A TWIST
For modern offshore vessels, azimuth thrusters are the most common dieselelectric propulsion system. But this makes the vessel more vulnerable, especially in tough arctic seas, as a breakdown to the angle gears and other mechanical parts often means heading to dry dock for repair.

A more reliable alternative can be conventional diesel-electric or dieselmechanical propulsion with a long shaft and machinery positioned inside the hull. But the gear and electric motor take up valuable space, and is also difficult to retrofit on an azimuth-fitted vessel.

The solution 
Odense Maritime Technology, Caterpillar Marine and Scandinavian Marine Group got together to develop the compact Twin Fin design based on well-proven and robust components.

 

Picture below: First Twin Fin fitted vessel is a retrofit delivered from Damen Group - Shipdoc Yard Amsterdam It is a Seismic Survey Vessel ‘NAILA’ type Ulstein SX124 belonging to Owner Polarcus DMCC.

Two existing azimuth thrusters are exchanged with Twin Fin increasing the bollard pull with almost 40% equivalent to the fuel saving obtained with the conversion.
