Ballast tanks on ships are used in various modes - completely filled with seawater, partially filled, or sometimes completely empty. It is the normal practice to coat the interior of the tanks with a suitable coating and also apply cathodic protection (CP). During service, the interiors of the ballast tanks are exposed to complete immersion in seawater when they are full. When half full, the top half of the tank interior is exposed to moist, salt-laden air while the bottom half is completely immersed. When completely empty, the tank interior only has moist salt-laden air. A project was undertaken to study the performance of some marine coatings under simulated ballast tank conditions by utilizing a large (2000-gallon) mock-up ballast tank. The impact of the type of surface preparation, in particular abrasive blasting (AB) and ultra high pressure waterjetting (UHP-WJ), on coating performance was investigated and the results are reported in the paper. © 2011 by NACE International.

Pipeline monitoring technologies including coupons, corrosion rate probes, dataloggers, and remote monitoring are an essential part of the arsenal to combat stray current interference. Because too much CP can accelerate corrosion influenced by AC, CP levels must be optimized - corrosion rate probes help in this regard. A presentation covers stray current and stray current control; a case study of a transit system, the MARTA subway in Atlanta, GA; and a case involving a 20-mi long high pressure natural gas pipeline, 3 mi from transit system at closest point. This is an abstract of a paper presented at the 2013 AGA Operations Conference (Orlando, FL 5/21-24/2013).

A seachest is a void space or box on the body of a marine vessel below the water line from which piping systems draw raw water for cooling or other uses such as ballasting of the vessel and fire-fighting. The inlet grid or intake of the seachest, which is protected by a grating, can vary in size from under 1 sq. meter for a small inland tug to several hundred sq. meters for a large vessel like an oil tanker. The seachest is normally fabricated from carbon steel like the rest of the vessel, while the adjoining piping and valves are nonferrous. Zinc anodes in combination with coatings are used for the corrosion protection of the ship's hull as well as the seachest. A waster-sleeve, typically fabricated from 0.375-inch (9.52 mm) thick carbon steel plate, is recommended as additional sacrificial protection for the non-ferrous components with a projected service life of 10-12 years or more. Since the waster sleeves (as well as adjoining non-ferrous components) are electrically continuous to each other, they also receive some protection from the zinc anodes. Replacement of waster-sleeves is a high cost item. Depending on the size of the waster-sleeves, dry-dock replacement installation can cost anywhere from $5,000 to $25,000 while underwater installations can be as much as $200,000. Hence, early failure of these and other seachest components can seriously impact the extended life cycle goals for these vessels. During the nineties, premature failure of waster-sleeves were observed on a number of ocean-going vessels. Based on shipyard surveys of failed waster sleeves it was found that the standard thickness of 0.375 in (9.52 mm) was not sufficient to survive the desired 12-year service life and even doubling the thickness only had marginal effect. Engineering analysis indicated that the existing CP design utilizing only 2 to 4 pieces of 42-lb (19.1 Kg) Zn anodes was inadequate and a re-designed CP system with a larger number of anodes would possibly solve the problem. © 2016 by NACE International.


Surface preparation, whether using conventional abrasive blasting (AB), high pressure waterjetting (HP-WJ) or ultra high pressure waterjetting (UHP-WJ), and subsequent application of coatings inside closed spaces in marine vessels such as ballast tanks and bilges, present unique challenges. There are also some logistical, cost, and safety concerns in performing such work. The present paper discusses the findings of a project that was undertaken to identify the operational protocols and technical issues that may be encountered in surface preparation and coating application inside shipboard tanks. The work was performed in a laboratory setting by utilizing a large (2000-gallon capacity), specially designed mock-up ballast tank. Guidelines for UHP-WJ and coating application that were developed as a result of the work are presented in the paper. © 2011 by NACE International.

Pipelines are often located on alternating current (AC) overhead transmission line rights-of-way. Under these circumstances, the likelihood of AC interference and AC corrosion must be evaluated. AC interference can cause elevated step and touch voltages that create unsafe conditions for the pipeline operator and the public. Pipeline construction near AC transmission lines requires additional safety measures. Part 1 of this article covers safety considerations and Part 2 (in the October 2014 issue of MP) will present an example of a pipeline project that illustrates advances in predictive modeling and the design of AC interference mitigation and monitoring.

Corrosion/erosion management for an operation is the systematic application of policies, practices, and resources to control corrosion/erosion and provide reliable safeguards against unexpected failures and leaks that can jeopardize mechanical integrity, operation, health, safety and environment (HSE). This paper highlights the use of a single key performance indicator in tracking monitoring strategy, mitigation strategy, and pipeline integrity for aboveground pipelines in the North Slope. The approach enables the integration of corrosion/erosion control, process monitoring, inspection, mitigation, environmental control, and materials management into a comprehensive management strategy. In this instance, external corrosion and stress corrosion cracking are effectively controlled; consequently, internal corrosion becomes the sole time-dependent failure type. Internal corrosion rate, like any KPI, enables the organization to operate with greater efficiency, reliability and control. The approach underscores a strategy that ensures that the facility remains fit for purpose during its design life. It satisfies the need to proactively control corrosion from growing to a size that could affect the structural integrity of components so that the facility remains sound and capable of safely performing the tasks for which it was designed and is compliant with the applicable regulations and standards governing design, operation, and maintenance. ©2012 by NACE International.

Special precautions are required for the application of marine and other coating systems on steel surfaces prepared by Ultra High Pressure Waterjetting (UHP-WJ) and having flash rust. Coating manufactures also stipulate strict guidelines and pre-conditions for the use and guarantee of their systems if these are to be applied on UHP-WJ surfaces. This paper presents the results of testing of some high performance marine coatings that were applied on steel panels prepared by UHP-WJ, and exposed to natural seawater over a 12-month period. Results of cathodic disbondment tests on the same coatings are also reported. Coating application, testing and performance assessment were carried out using standard protocols. On the basis of the present data it appears that solvent free moisture tolerant epoxy systems can perform equally well or better on UHP-WJ surfaces with a light to moderate flash rust compared to Abrasive Grit Blasted (AB) surfaces, provided no Cathodic Protection is applied.
