Two tugs have been launched and two towboats completed in North American shipyards as deliveries in the US and Canada get underway after a slow start
ABD Boats shipyard in North Vancouver, British Columbia is launching a new tug for North Arm Transportation. North Arm Tempest will work on the Fraser River once it is completed. This 19.7-m tug has a beam of 8.2 m, azimuth thrusters, and a pair of Cummins KTA38-M main engines each producing 745 kW at 1,800 rpm. These drive two Veth Propulsion-manufactured Z-drives through torsional flexible couplings and composite shafts.
In Oregon, US, a small 7.9-m tugboat was launched for the US Army Corps of Engineers. WCT Marine & Construction built this shallow-draught vessel to remove floating material around a dam. It will be deployed on the Snake River in Washington state in Q2 2021. This tug has a pair of Cummins 6.7 QSB keel-cooled engines turning two four-blade propellers through ZF 325-I reduction gears.
Near the end of February, Sheridan Shipyard completed 21.3-m towboat Dwain Harper for parent company McGinnis Inc, with 1,190 kW of towage power from two Mitsubishi S6R2 main engines, each producing 560 kW of power at 1,400 rpm. These turn Michigan Wheel-supplied propellers via Twin Disc MG5321 reduction gears.
This followed the delivery of towboat Jared Phillips to Parker Towing in February. Built by FMT Shipyard & Repair in Harvey, Louisiana, it has a pair of Caterpillar main engines driving propellers through reduction gears for towing barges along the Mississippi River.
In Alabama, Cooper Marine & Timberlands (CMT) is preparing to take delivery of a second towboat Blakeley BoatWorks is building in Mobile. It will operate Gretchen Cooper on the Lower Mississippi River from Q2 2021. This 33.5-m towboat will have installed power of 2,535 kW and will be larger than towboat newbuilding Mary Lynn Cooper, which Blakeley BoatWorks completed for CMT in October 2020.
In California, two pilot vessels have been delivered to Los Angeles Pilot Service. Angels Pilot and Angels Navigator have overall lengths of 17.1 m. They were designed by Camarc and constructed by Vigor Industrial in Vancouver, Washington state.
In Port Milwaukee, sunken icebreaking workboat Harbor Seagull has been raised and placed on a barge for inspection.
