Work continues on the Arthur Foss
Every year the Arthur‘s engine gets better and easier to work on. The last five years of classes and some very involved maintenance has gotten all the parts freed up and we’ve acquired more of the tools required to easily accomplish repairs and maintenance. The engine sounds great, too – when running unloaded and slow we still have every cylinder firing.
Preparing for Engineer for a Day
Nothing focuses a group like urgency.
I began work with the Anchor Program on Tuesday to prepare the Arthur Foss the fireboat Duwamish and the Historic Ships Wharf at Lake Union Park for the annual high school Engineer for a Day class on Friday. The class teaches kids from the Ballard Maritime Academy about marine engineering and goes from the Arthur to the Duwamish to the steamer Virginia V to learn about each system. Like Arthur, the class gets a better every year.
With TAP’s help, we got all the engines running on both the fireboat and the Arthur, despite dead batteries, broken fuel lines, and dirt and grime everywhere. We had the main and both generators going on Arthur and both generators and the three mains on the Duwamish all going. It was great!
TAP also helped us get the wharf cleaned up and the fireboat pressure-washed and the tug scrubbed. Thanks for all your help, guys – we’ll have more work days like that soon.
High school on the wharf
On Friday morning, three engineers stood on the Historic Ship Wharf next to three historic ships open and inviting with eight diesel engines warming up for class. We were more prepared to day than the previous 3 high school classes down here.
For the fourth year, our Ballard High School class got to experience a marine engineer’s work and realize that the is the same even when the engine room is wildly different. They visited a reciprocating steam plant, a direct-reversing diesel plant, and a diesel electric plant all in the same day visit. They prepped and started up many engines throughout the day to give them the full experience and demonstrate how to operate the engines.
We did have one setback: the starter in the fireboat’s main generator went out, so the class exercise was a little limited, but part of why we hold the class is to exercise the equipment and try to find problems before they become larger issues. I would call the class a great success and we’ll fix that starter soon.
Work continues on the yarder’s injectors
We kept working on the fuel injectors diesel yarder in Eureka. This is the part of the job that is hard on the hands and fairly boring, since I insist that all the parts thread together interchangeably and entirely. It’s common for parts of these antique diesel engines to distort: the threads stretch, they rust, and tips flare the mating surface. Also, years of using pipe wrenches instead of spanner wrenches and hammers instead of heat beats the parts up further. I machine and lap everything and test every part against every other part to get them all fitting right. The process is tedious but it increases confidence when assembling, since every part fits the way it should.
Work begins on the Lightship No. 83
We dove into the Lightship No. 83 project this week: OTM Inc’s first task as Project Manager is to assemble a plan and supporting documents (like charts and tables) and prepare specifications for when we request bids for the work. It’s not like hammering on the hull or tracing leaks in the plumbing, but it’s really important work and it’s great to finally start on it.
