Exhaust Insulation for Puget Sound Tugs and Workboats
Tugs, push boats, crew boats, landing craft and other workboats on Puget Sound share a few things: big diesels, long hours, tight engine rooms and crews who are in and out of those spaces all day. That makes exhaust insulation a safety and maintenance item, not an afterthought. Here's how removable, made-to-measure exhaust insulation fits a working boat, and how to order it from our shop in Blaine.
Why workboats are hard on exhaust insulation
Hours. A boat that runs most of the day puts a lot of heat cycles through its exhaust and anything wrapped around it.
Vibration. Big diesels shake things loose. Wrap and tape that's fine on a weekend boat can work loose on a working one.
Constant maintenance. Workboat engines get serviced often. Every time traditional lagging is cut off to reach a gasket or a sensor, there's a chance it doesn't go back on properly.
People in the space. Engineers and deckhands move around the engine room under way. Bare exhaust is a burn hazard.
What removable exhaust covers fix
A removable cover is sewn to the shape of one part (a riser, elbow, muffler, straight run or turbo outlet) and closes with fasteners. On a workboat that means:
Service without destroying the insulation. The mechanic opens the section they need, does the job and closes it back up.
Sections that match the system. Covers are split at joints and flanges, so one service point doesn't mean removing the whole run.
Closures that stay put. For high-vibration marine engines, stainless lacing wire is the most reliable closure: it won't melt, stretch or shake loose. Snaps and D-rings are other options.
A tidier engine room. Fitted covers look and work better than patched-up wrap.
We compared the two approaches in Marine Exhaust Blanket vs. Exhaust Wrap.
What we build for working boats
We custom-fabricate covers for boat builders, fishing vessels, tugboats, workboats and ships, including:
Dry exhaust risers, elbows and straight pipe
Turbo outlets
Mufflers
Generator exhaust (see our generator exhaust blankets)
Piping and valves in the engine room
For high-temperature exhaust builds, our inner insulation is rated 1,000°F continuous (1,200°F max) and our gray outer cloth is rated 450°F continuous (500°F max), with a stainless wire mesh hot face against the pipe. Tell us your operating temperatures and we'll match the build. More detail is on our marine exhaust insulation blankets page.
Ordering from anywhere on Puget Sound
We're based in Blaine, at the top of Western Washington, and serve Seattle, Everett, Anacortes, Bellingham and the rest of the region. We don't install. We manufacture the covers and ship them, and your engineer, crew or yard fits them. That keeps the boat working while the covers are made.
How to order:
Photograph the exhaust system end to end, from several angles, including what sits close to each section.
Note the engine make and model and any part numbers on risers, elbows or mufflers.
Measure pipe size or circumference, lengths, elbow heel and throat, and the centers of any cutouts. Our measuring guide shows how. Measure cold.
Talk it through. The owner goes over your photos and measurements with you by phone or video before we build.
We make single replacement sections and full sets. If your boat also works in Alaska, we ship anywhere in Alaska too. For more on our Seattle-area work, see marine insulation in Seattle.
FAQ
Can you build covers to match the old ones? Send photos of the old covers along with the bare parts if you can. Measurements of the bare pipe and fittings are what we build from.
We only need one section replaced. Is that worth a quote? Yes. We build single covers as well as full systems, big job or small.
Do you come to the boat? We're a manufacturer only, and we don't install. We work from your photos and measurements, with the owner helping by phone or video.
