Cargo tank coating refurbishment / Alan Walker in JOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL), Vol. 34, N° 11 (11/2017)  

[article]  inJOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL) > Vol. 34, N° 11 (11/2017) . - p. 22-26 Titre : Cargo tank coating refurbishment Type de document : texte imprimé Auteurs : Alan Walker, Auteur Année de publication : 2017 Article en page(s) : p. 22-26 Langues : Américain (ame) Catégories : Bateaux -- Entretien et réparations Corrosion Coût -- Contrôle Entretien et réparations Réservoirs (récipients) Revêtements protecteurs Traitement de surface par impact Index. décimale : 667.9 Revêtements et enduits Résumé : Keeping costs down in a maintenance painting project is a major concern for asset owners in all industries, but critical for those in the marine business. The operators of seagoing vessels know that they are only profitable when they are carrying cargo or passengers, and in the case of product carriers, the more versatile they are as far as the different types of liquids they can carry, the more often they will be in revenue-earning service. Thus, when these vessels are due for scheduled maintenance dry-docking, it is essential that this is planned carefully to ensure that the proper surface preparation is carried out and that the protective coating applied is suitable for the owner’s requirements. This not only keeps costs down, but also makes certain that the vessels are in dry-dock for the minimum time, and thus returned to revenue service as quickly as possible. Note de contenu : - Fig. 1.

Evaluating material loss of steel under protective coatings in marine environments / Patrick Cassidy in JOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL), Vol. 35, N° 4 (04/2018)  

[article]  inJOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL) > Vol. 35, N° 4 (04/2018) . - p. 24-34 Titre : Evaluating material loss of steel under protective coatings in marine environments Type de document : texte imprimé Auteurs : Patrick Cassidy, Auteur ; James A. Ellor, Auteur ; John Wegand, Auteur ; James Martin, Auteur ; Paul Slebodnick, Auteur ; James Tagert, Auteur Année de publication : 2018 Article en page(s) : p. 24-34 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique. L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1. C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères. Test d'immersion Index. décimale : 667.9 Revêtements et enduits Résumé : Over the past 20 years, the U.S. Navy has implemented the use of advanced ultra-high-solids (UHS) coatings for the protection of ship tanks and voids to extend the life of tank coatings. In areas of breakdown, the maintenance community needs a suitable touch-up and repair coating and as part of this ongoing effort, the Navy sought methods to improve basic coating test methods to better assess repair coating performance. This article describes this testing, the goal of which is to project greater than 10 years of service life.

Extending fish hold tank maintenance intervals on the F/V Cornelia Marie / Ray Meador in JOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL), Vol. 35, N° 9 (09-10/2018)

[article]  inJOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL) > Vol. 35, N° 9 (09-10/2018) . - p. 18-22 Titre : Extending fish hold tank maintenance intervals on the F/V Cornelia Marie Type de document : texte imprimé Auteurs : Ray Meador, Auteur Année de publication : 2018 Article en page(s) : p. 18-22 Langues : Américain (ame) Catégories : Bateaux -- Entretien et réparations Bateaux -- Revêtements:Bateaux -- Peinture Epoxydes Haut extrait sec Polyamines Revêtements protecteurs Index. décimale : 667.9 Revêtements et enduits 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". Note de contenu : - 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 Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=31892 [article]
