I became a marine surveyor because I was fascinated with boating. I have remained a marine surveyor for over thirty years because I am fascinated with the trade and the opportunity to learn new things regularly. Below is an excerpt from an interesting email from a client.
This was a prepurchase survey on a recreational tugboat. He began his email that he regretted that he wouldn’t be able to attend the inspection and the opportunity to learn from me, but he had an opportunity to “give her a once over” and he included the following information, some tests of his own – here are the results:
“I’m particularly concerned with the state of the engine, even though just 1254 hours, as it would be difficult/expensive to replace so: (1) Engine oil and transmission oil, microscopic analysis, no overt metal swarf; recent engine oil analysis acceptable. (2) Prompt cold start. While running cold, stethoscopic inspection of injectors showed variance in #3 and #6 injectors (counting from bow), which resolved as engine warmed; no audible problems with valve chain above each cylinder. (3) No air pressure pulses from open oil filler cap, so likely acceptable rings and cylinder lining. (4) Stethoscopic inspection for exhaust manifold leaks appeared negative. (5) Sample taken of coolant. Subsequent lab test of sample showed minimal sodium contamination, indicating no pinhole leaks in heat exchanger. (6) After running for an hour during bay trial, a thermal camera image of the engine showed all cylinders at identical temperatures, and all exhaust manifold legs also at identical temperatures, indicating all cylinders are operating identically.
I took an H20 sample from the non-filtered galley sink supply. Subsequent lab tests indicate it was acceptably clear of bacteria (48-hur incubation), alkalinity, chlorine, nitrates & nitrates, & lead.
I placed uncovered petri dishes with potato starch/agar media in the focsle, the head shower, and behind the entryway stepladder, then after one hour exposure sealed them. Subsequent laboratory incubation for 24 hours disclosed minimal airborne mold.
The electrically flushed toilet smelled and looked fine, until I flushed it once; then it smelled overpoweringly of hydrogen sulfide. If you have any thoughts about this, that would be great.
Kells, I’m looking forward to learning about whatever you find!”
Some (scientist) clients are more detailed than others. Though some of the tests require a laboratory, many are simple and can be done by all. I smile as I recall this email and this brilliant human’s desire to learn from me, I certainly would have learned more had he attended that day!
Today I will inspect another boat, learn something new, smile, and be grateful for the opportunity.
