By changing to a nautican propulsion system, the F/V Raven saw significant gains in speed and fuel economy:
F/V Raven Sees Notable Gains
- A measured increase of 13% in bollard pull,
- A measured reduction in horsepower to achieve same vessel speed,
- An increase in speed on average of over 1 knot and reduced fuel consumption at a given RPM,
- A net average increase in fuel economy (nm/gal) of over 20%, and
- A significant improvement in steering noted by the crew.
The Kim M. Bouchard is the first ATB from Bouchard Transportation fitted with Nautican Integrated Propulsion Units (IPUs). The vessel is a 10,000-hp, twin screw ATB tug, classed by ABS as an A1 Towing Vessel, Dual Mode ATB, and USCG Subchapter M. The Kim M. Bouchard will pair up with Barge B. No. 270, which has a 250,000-bbl. capacity. Read more...

Nautican Units Exceed Expectations
The Reinauer Transportation Companies of New York have continued to expand their fleet for many years at the Senesco Marine yard in Rhode Island. Reinauer introduced the Ruth-class in 2008, and the slightly shorter and narrower B. Franklin-class in 2012. Read more...
Proven Performance Gains for ATBs
Nautican Units Offer Improved Speed, Power and Maneuverability
The Glenn Edwards is part of the Manson fleet of hopper dredge vessels and is the largest capacity trailing suction hopper dredge in the United States. Dredge vessels offer channel and harbor maintenance as well as upland disposal and beach nourishment. The Glenn Edwards stores just over 10,000 square meters of dredged material in hoppers to transport to disposal sites, or can disperse the material directly through discharge outlets. Read more...

Nautican Units Maximize Speed and Performance for Manson Hopper Dredge
An international collaboration came together in the construction of a new river pusher tug. Concordia of the Netherlands designed the RP6000 tug for the Japanese and South American owned Astillero Tsuneishi Shipyard, using Nautican high-efficiency nozzles and Nautican’s triple-rudder design. This is the first tug for the Astillero Tsuneishi Shipyard, established in a remote region of Paraguay in 2008. Read more...

Nautican Units Offer Proven Performance Gains in Shallow Water Applications
Nautican installed customized, high-efficiency nozzles and triple rudders on the pusher-towing tug, the Edgar Kotokak. This refit significantly increased the vessel’s thrust, maneuverability and fuel efficiency, generating significant cost savings. Additionally, by supplying the nozzles and rudders as an integrated unit, Nautican reduced shipyard installation time and cost. Read more...
First Application of Integrated Nautican Nozzles and Rudders Drives Improved Performance
Nautican installed its High-Efficiency Nozzles, Triple Rudders and Propellers on the 108 foot, twin screw, ocean going tug, Hoku Ke’a, to give the vessel the muscle to tow larger barges while at the same time maintaining inter-island transit times. Read more...
Integrated Nautican Nozzles and Rudders Reduce Shipyard Installation Time and Improve Vessel Performance
Nautican installed high-efficiency Triple Rudders to improve the steering capability on the Island Monarch, the pusher tug of an ocean-going Articulated Tug Barge (ATB). The rudders significantly improved the Island Monarch’s handling and enabled the tug – with her relatively low 3000 horsepower – to turn the barge safely and quickly. Read more...
