Pacific
Northwest Section On April 17, 2004, SNAME’s Pacific Northwest Section held a technical meeting in Portland, OR. There were nearly 20 people in attendance mostly from the greater Portland area, but also represented were Seattle, WA and Vancouver, BC. The group enjoyed a vessel tour at the local marine fire station followed by an excellent meal and presentation at the Portland Marriott Hotel. The meeting started at 10:30 am Saturday morning with the group gathering at Portland Fire Bureau’s Station No. 6 on the Willamette River. Chief engineer, Mick Carpenter, senior pilot, Rob Johnson, and crewmember, Cliff Phillips, provided a brief history of the fire station and its 77-year-old fireboat, DAVID CAMPBELL, before taking the group down to the dock for a closer look. The Baker Construction Company built the DAVID CAMPBELL in 1927 along with two sister vessels for the Portland Fire Bureau. The two sister vessels were sold many years ago as the city was forced to cutback its services due to fiscal constraints.

The riveted steel hull has an overall length of 87’-6” and breadth of 20’-6”. She only draws 6’-0” of water allowing her to work in many shallow reaches of the two rivers in the Portland area. The original Sterling gasoline engines that powered the vessel were replaced in 1959 by Hall-Scott gas engines. The present Cummins diesel engines were installed in 1974. Two V-12 engines of 340 brake horsepower provide propulsion while each also has the ability to be clutched into a fire pump off the front end. Twin Disc Omega drives allow the power to be split between the fire pumps and propellers at an infinitely variable ratio. In addition, two identical V-12 engines provide dedicated power to another set of fire pumps giving a total pump capacity of approximately 9,000 gallons per minute at 150 psi. The boat has two 2,000 gpm monitors at the bow and a large 5-inch monitor mounted on the centerline just aft of the wheelhouse that has been measured at nearly 8,500 gpm. The crew explained that the thrust from the large monitor is so great that when pointed aft the boat will move along at 13 knots without assistance from the propellers! Many thanks go to the Portland Fire Bureau and the crew of the fireboat for an excellent tour. We would also like to thank Portland Harbor Master, Chris Payne, who was instrumental in coordinating the tour.
