| Résumé : |
In the commercial fishing industry, as with any other industry in which corrosion can affect the bottom line. And when a vessel shows up at a processing plant with fish hold tanks containing rusty water or floating paint chips, the processor may refuse the contaminated load, causing the owner to lose out on an entire haul.
Proactively addressing fish hold maintenance can be tough for vessel owners, as the thin-film polyamide epoxy coatings traditionally used to coat fish holds need to cure for about a week before returning the tanks to service. That's a lot of downtime to plan for in dry-dock when other areas of the vessel are likely prioritized for coatings maintenance. Making matters worse, the polyamide epoxy coatings typically last only about five years, forcing vessel owners to keep up with short maintenance intervals. McManus prefers to take his risks crabbing in the unforgiving Bering Sea — not at a sea-food processing facility where a contaminated load of king crab could mean a loss of more than $560,000 per fish hold at dock prices. To protect potential catch, he recently restored six fish holds of his boat.
In doing so, he also made a strategic specification change based on the recommendation from a global coating manufacturer's technical representative to switch from a traditional polyamide epoxy coating to a more durable ultra-high-solids epoxy amine coating that could deliver a longer service life and triple the expected fish hold maintenance interval to about 15 years.
"The beauty in the fish hold coating application was in prepping the tanks efficiently, coating them within a couple of days, and returning them to service 24 hours later, knowing that we may not have to redo them for another 15 years". |

- Fish hold restoration
- Hull, freeboard and superstructure reconditioning
- Fig. 1 and 2 : The Cornelia Marie's six fish holds showed visible signs of corrosion
- Fig. 3 : Abrasive blast-cleaning the fish holds to an SSPC SP-10 standard removed all coatings and contaminants from th esteel substrates
- Fig. 4 and 5 : An epoxy coating was applied at a 20-to-30-mils DFT over all the fish hold surfaces, including sharp edges, corners and grates
- Fig. 6 : The Cornelia Marie crew applied three coats of epoxy to the vessel's main deck by brush and roller
- Fig. 7 : Work on the underwater hull and freeboard of the Cornelia Marie involved taking the surface down to an existing tight antifouling coat, priming exposed bare steel, edge feathering above the waterline and spray-applying primer, an antifouling epoxy and an acrylic polyurethane gloss coating |
