CANBY FERRY PROPULSION SYSTEM REPLACEMENT

Art Anderson played a pivotal role in the development and modernization of Clackamas County’s Canby Ferry, the M.J. LEE, which transports vehicles and pedestrians across the Willamette River near Canby, Oregon. The vessel accommodates up to 9 automobiles and 49 passengers, including trucks, farm equipment, RVs, and bicycles.

From 1994 to 1997, Art Anderson provided comprehensive services for the ferry’s original design:

1994: Conducted a feasibility and economic study.
1995: Delivered concept and full contract design packages, including plans, specifications, and cost estimates.
1997: Acted as the owner’s representative during construction.

In 2010, Art Anderson was contracted again to support upgrades during the ferry’s extended drydock in 2011-2012. The original design featured an electro-hydraulic propulsion system powered by overhead trolley wires. The County sought to replace the deck-mounted Z-drive thrusters with a fully electric system that would still use the existing trolley power source.

Upgrade design services were delivered in three phases:

Task 1: Feasibility and Concept Design

Verified vessel conditions against County-provided documentation.
Conducted a feasibility study evaluating propulsion alternatives, electric load analysis, and retention of existing power infrastructure.
Developed concept designs with preliminary drawings, specifications, and cost estimates.
Submitted approved design documents to the U.S. Coast Guard.

Task 2: Final Design Development

Completed upgrade design drawings, specifications, and cost estimates to 100% for inclusion in bid documents.

Task 3: Bid and Construction Support

Assisted the County in preparing public bid documents and responding to bidder inquiries.
Provided construction support during the drydock period.

Additional optional improvements included:

Replacement of hydraulic pipes and hoses for ramp/barrier actuation, emphasizing noise reduction.
Specification of vegetable-based hydraulic fluid to reduce environmental risk.
Installation of quick-acting, watertight manhole hatches.
Modifications to resolve sea valve issues.
Enhanced ramp lifting system to extend wire rope longevity.
Addition of an air conditioning unit to the pilot house.

Art Anderson also:

Studied electrical panel locations for improved access and reduced voltage drop.
Relocated below-deck electrical gear above deck.
Improved switchboard access.
Designed an air-cooled backup generator.
Replaced incandescent running lights with LEDs.

Finally, Art Anderson provided complete As-Built drawings for the County’s maintenance and overhaul records.
