Jensen Maritime to Design Two 120' Tugboats

Jensen Maritime, Crowley Maritime Corp.’s Seattle-based naval architecture and marine engineering company, was recently selected to provide the ABS Class and functional designs for two, new 120-foot twin screw tugboats for Ice Flow, LLC dba Nichols Brothers Boat Builders (NBBB) and Kirby Offshore Marine, LLC.

“Jensen is proud to have been chosen as the design firm on this project and looks forward to seeing the vessels through from concept to completion,” said Johan Sperling, vice president, Jensen Maritime. “We will imbed a full-time Jensen designer in the shipyard for the duration of this project to help with system design and to ensure that the tugboats are built to exacting specifications.”
 

The two, 120-foot long, 35-foot wide tugboats, which will be used for tow operations, will be powered by two Caterpillar 3516C, 2447 BHP at 1600 rpm main engines with Reintjes reduction gears turning two NautiCAN fixed-pitch propellers with fixed nozzles. These vessels will also have two C7.1 Caterpillar generators for electrical service, one TESD-34 Markey tow winch, one CEW-60 Markey electric capstan and one Smith Berger Town Pin.
 

Keels will be laid for both vessels this fall with complete vessel delivery scheduled for May and November 2017.  Both vessels will be fully classed by ABS and compliant with U.S. Coast Guard, as required at delivery.
