A Novel Quick Turn-Around Repair Coating For Offshore Windmills

Product Number: 51323-19481-SG
Author: Hindrik Harm Broesder, Dinko Cudic
Publication Date: 2023
$20.00

Offshore wind towers are commonly foreseen with factory-applied anti-corrosion coatings that consist of
multi-layer 2-component protective paint systems like epoxies or polyurethanes. These coating systems have various requirements in place for application and curing conditions like a high degree of surface cleanliness of steel, roughness profile for achieving proper adhesion, low levels of salt contamination on the surface, and appropriate control of temperature and humidity during curing. During transport and installation of the coated towers, the factory-applied coating often gets damaged.

An Innovative Thermoplastic Coating For CUI Applications

Product Number: 51322-18122-SG
Author: Hindrik Harm Broesder, Somaieh Salehpour, Dinko Cudic
Publication Date: 2022
$20.00

An innovative thermoplastic type of coating material based on pure isobutene homopolymer was investigated to determine whether it would be fit for purpose in CUI services at low and moderate temperatures up to 120 °C. This polymer is commonly called Polyisobutene (PIB) and has a unique set of properties that are beneficial for protecting metallic structures from corrosion. Polyisobutene is a polyolefin with a chemical structure similar to Polyethylene (PE) and Polypropylene (PP). One of the major differences is that PE and PP are solid materials with a high degree of crystallinity, whereas PIB does not have a crystallization or melting temperature. PIB has a glass transition temperature (Tg) below – 60 °C which indicates that the polymer is a liquid above this temperature.

Ensuring Additional Mechanical Protection of HDD Coatings

Product Number: 51323-19549-SG
Author: David B. Futch, Ron Raphoon
Publication Date: 2023
$20.00

As onshore pipeline rights-of-way become more congested and urban sprawl increases, the number of horizontal directional drills (HDDs) will likely increase. HDD is a trenchless pipeline installation method that requires drilling a larger pilot hole where the mainline pipe can be subsequently pulled through the drilled hole. However, HDDs have an increased probability for coating damage, even when coated with traditional mill or field applied abrasion resistant overcoat (ARO).

Implementation of Pulsed Laser Ablation Technology in Surface Preparation Processes

Product Number: 51324-20982-SG
Author: Matt Binsfield
Publication Date: 2024
$40.00
The transition of pulsed laser ablation (PLA) technology into the hands of maintainers within shipyards and the transportation industry requires an assessment of multiple factors. From the technical perspective relative to surface preparation and corrosion mitigation, it is essential to understand the impact of PLA energy into substrates and the resultant adhesion characteristics of subsequent coatings. Technical areas to be discussed include metallurgical properties, such as stress corrosion cracking, weldability, bulk properties, fatigue life, as well as adhesion. The effective application of laser ablation is of critical concern to preservation professionals, which requires an understanding of how the process works, the proper appearance of a laser ablated surface, whether that is a tightly adhered existing coating prepared for re-coating, or to expose some or all of the base metal substrate. Accordingly, both laser operators and inspectors need specific information and training to appropriately use the technology to meet preservation objectives and requirements. These needs will be addressed through a forthcoming AMPP Laser Ablation Standard, Technical Guide, and Visual Guide. Determining where to apply PLA based on extensive test data currently available, as well as understanding where future investigation is required, will be summarized.

Laboratory And Full-Scale Qualification Of An Abrasion Resistant Overcoat Wrap

Product Number: 51322-17633-SG

Publication Date: 2022

As onshore pipeline rights-of-way become more congested and urban sprawl increases, the number of horizontal directional drills (HDDs) will likely increase. HDD is a trenchless pipeline installation method that requires drilling a larger pilot hole where the mainline pipe can be subsequently pulled through the drilled hole. However, HDDs have an increased probability for coating damage, even when coated with traditional mill or field applied abrasion resistant overcoat (ARO). This coating damage includes abrasion, impact, gouging, denting, tearing, bending, etc. and that damage may exist for the life of the pipeline due to an HDD being inaccessible for future maintenance.
