Back on afternoons this upcoming week, so I’m hoping to have more academic related things, but for this week what I have for you is more Ferry related things.
let’s starts with some Ongiara related photos. Toronto’s car ferry arrived back from drydock on Thursday, and with really high winds on Friday, we spent much of that day preparing it for service on Saturday.
Here are some photos from the Ongiara’s engineroom. It is powered by a pair of Cat C12 diesel engines (one bow, one stern). Check out the Engineering room controls for the engines. 675 rpm is the idle setting. It’s fast enough so that when your bow engine is free-spinning (idling), and then you clutch in to slow the ferry down, there’s enough power to avoid the engine stalling.
This is the prettiest that Ongiara is going to look for the next 5 years. Personally, I rather like the new blue upholstery in the passenger cabins with the new wood trim, it looks good. And the replacement windows are good too.
Next, here are some photos from the Trillium, specifically of the boiler for the steam engine.
So the reason that the Trillium‘s boiler is open is that a number of tubes burst last year and they need to be replaced. It’s important to know that this boiler was built when the Trillium was rebuilt in the 1970s. Prior to that it had been rotting and neglected in the lagoons of Toronto Island. So much so that at some point in the early 1970s, during a particularly high water year my colleague’s parents canoed through the Trillium (I’m guessing the lower rather than upper deck). This is a firetube boiler, and If I understand it properly, the primary benefit of a firetube boiler is that it means that the engineers on the Trillium can use lakewater, or at least- doesn’t need extremely clean water.
Here we have a picture of the Detroit Diesel engine that powers the Trillium‘s two azimuthal thrusters- needed because the two side paddles use a single axle and cannot rotate in different directions.
and now, two videos of icebreaking on our way across the harbour, just for fun. These are from our sea trial, on our way to Hanlan’s Point slip.
