Kirby Vessels First to Have Completely Integrated Nautican Propulsion, Shafting and Steering System.

Nichols Brothers Boat Builders are constructing two ocean towing vessels for Kirby: Hulls S186 and S187. Both vessels are equipped with complete propulsion systems supplied by Nautican, comprising everything aft of the gearbox companion flange: shafts and bearings, Nautican IPU (nozzles and propellers, triple-rudders and headbox), with the steering cylinder mounts and rudder stops integrated into the Nautican headbox. These are the first vessels in which Nautican has integrated these steering components in the factory, prior to shipment.

Nautican worked with the designer, Jensen Maritime and the shipyard, NBBB to integrate the Nautican system into the vessel. The Nautican system is mated to Caterpillar 3516B engines with Reintjes gears. Hull S186 is scheduled to launch at the end of this month, and Hull S187 later this year.
