Abstract

This research presents a comparative study focused on estimating the lifespan of galvanized steel pipes and stainless steel pipes within the context of a ballast system. Ballast systems play a crucial role in maintaining the stability and trim of vessels, making the longevity of the associated piping materials essential for maritime operations. This research aims to provide insights into the corrosion behavior and overall durability of galvanized steel and stainless steel pipes employed in ballast systems. The investigation involves an in-depth analysis of corrosion mechanisms specific to both galvanized steel and stainless steel pipes in the corrosive marine environment. The influence of factors such as salinity, and immersion time is examined. By understanding the distinct corrosion behavior of galvanized steel and stainless steel pipes, maritime industry stakeholders can make informed decisions regarding material selection, maintenance schedules, and potential retrofitting options. Ultimately, the insights gained from this study contribute to the sustainability and operational efficiency of maritime transport by enabling the optimization of ballast system infrastructure. As regulations and environmental considerations evolve, a comprehensive understanding of the lifespan estimation of galvanized steel and stainless steel pipes aids in mitigating potential failures, reducing downtime, and ensuring the safety and reliability of vessel operations. It is shown that the lifespan of stainless steel is longer than that of galvanized pipe.

Abstract

Corrosion on ships is a common challenge that arises due to the exposure of various metal components to the marine environment. It is a natural electrochemical process that deteriorates the integrity and performance of the ship's structures and equipment over time. The corrosive agents in the marine environment include seawater, humidity, salt spray, chemicals, and microbiological organisms. Corrosion can affect different parts of a ship, such as the hull, ballast tanks, pipelines, propellers, rudders, and various metallic fittings. It can lead to the weakening of structural components, reduced operational efficiency, increased maintenance costs, and even safety hazards. Therefore, it is essential to determine the limitations of the lifespan and efficiency of pipes concerning the influence of corrosion. In this study, the corrosion rate of Galvanized Steel Pipe SCH 40 and Stainless Steel 304 was estimated. The corrosion rate of pipes was evaluated by variating the influence of 3% and 6% salinity and immersion time 240, 360, and 720 hours. The result shows that the corrosion rate tends to increase in higher salinity and immersion time.
