Ketchikan, Alaska, headquarteredBoyer Towing Inc has actually lately repowered its 80 foot by 30 foot pull Gretchen H.
Delivered by Rodriguez Shipbuilding, Inc., Coden, Ala., in 1997, the vessel was obtained by Boyer in 2005.
As with lots of Rodriguez- constructed yanks, the Gretchen H. has three-way props as well as three-way engines. When Boyer Towing chose to repower the vessel, its option was to change the earlier Lugger engines, ranked at 700 hp each, with 3 brand-new Cummins QSK19 Tier 3 certified engines ranked at 750 hp each at 1,800 RPM. The existing Twin Disc MG5202DC equipments with their 6.1:1 proportions were a great suitable for the brand-new engines so they were preserved.
Boyer performed the repower at its very own Seattle shipyard.
According to Cummins, the pull carried out faultlessly on sea tests at the end of January as well as prepares to return to function pulling barges in between Seattle, Wake Island, or Alaska.
