04298 Corrosion Evaluation of a High Performance Cu-Based Alloy for Seawater Applications

Product Number: 51300-04298-SG

ISBN: 04298 2004 CP

Author: John O. Ratka, Brush Wellman Inc.; Manuel N. Maligas, FMC Technologies

Publication Date: 2004

$20.00

In seawater, higher strength nickel-copper alloys are used as alternatives to copper alloys. These can be susceptible to chloride stress corrosion cracking and hydrogen embrittlement in conditions where cathodic protection is utilized. Copper-Nickel-Tin alloys (CuNiSn) show low corrosion rates in the free and coupled conditions. Resistance to hydrogen embrittlement is demonstrated.

AMPP SP21487-2021, Inspecting and Reporting Biofouling and Antifouling Systems’ Condition during Underwater Inspections on Ships

Product Number: AMPP SP21487-2021

Publication Date: 2021

$109.00

Biofouling accumulation on a ship’s hull has a direct impact on fuel consumption and associated greenhouse gas (GHG) emissions and may pose a biosecurity risk due to the presence of non-indigenous, potentially invasive aquatic species.

The antifouling system (AFS) is designed to protect the underwater surfaces from biofouling accumulation. Underwater inspections (UWI) of ships are typically carried out to monitor and verify the condition of the underwater hull and the AFS.

Recipients of UWI reports are reliant on the quality of information provided to make adequate decisions relating to hull performance, AFS condition and performance, biofouling management and associated risk assessments. Consistent and good quality reporting is key to effective underwater hull condition record-keeping and management.

Microbiological Profile and Risk Exposures in Topside Production Systems of FPSOs in West Africa

Product Number: 51322-18017-SG

Author: Kingsley Oparaodu, Ibiba Braide

Publication Date: 2022

$20.00

The incidence and proliferation of microbial population in oil and gas production facilities can have undesirable consequences on upstream, midstream and downstream production systems. Microbes thrive in the anaerobic conditions encountered in these systems and are supported by nutrients and metabolites found in produced water. Although the majority of process and water injection systems are susceptible to microbial fouling, the development of microbial activity is exacerbated by specific conditions such as stagnant fluids or the presence of deposits.¹ Threats of microbiologically influenced corrosion (MIC) and other challenges associated with microorganisms have become valid as more cases are reported. While MIC, biofouling (BF), and reservoir souring are three of the most common problems associated with microbes, many other production issues can be attributable to microbial activity including: employee infections, filter plugging, loss of injectivity, and metal sulfide deposits.²

Novel Heat-Conducting “Metallic” Coatings Against Biofouling And Biocorrosion

Product Number: 51322-18178-SG

Author: Di Wang, Timothy D. Hall, Tingyue Gu

Publication Date: 2022

$20.00

Seawater biofouling is a major threat in heat exchanger operations. It decreases the heat transfer efficiency and service life of heat exchangers^1,2. The formation of deposits caused by biofouling on the heat exchanger metal surfaces increases surface roughness and decreases cross-sectional flow area, which leads to higher friction loss in fluid flow^3,4. Mitigation methods, including surface scrubbing, fluidizing bed heat exchangers, cleaning-in-place and dosing anti-fouling chemicals, are the main ways to tackle biofouling⁵. Conventional approaches to treat biofouled components by periodic electrochlorination or acid flushes are costly and environmentally hazardous. Huge costs are associated with heat exchanger biofouling losses, but there is still a lack of research to develop heat-conducting antifouling coatings to heat exchangers³.
