Abstract:
Offshore oil and gas engineering faces one of the most critical challenges in materials selection: corrosion in aggressive marine environments. Prolonged exposure to seawater, high chloride concentrations, extreme pressures, and variable temperatures leads to significant degradation of conventional alloys, resulting in high maintenance costs, operational risks, and safety concerns. This research explores the development, properties, and applications of corrosion-resistant alloys (CRAs), with a particular focus on stainless steels, nickel-based alloys, and titanium alloys employed in subsea pipelines, risers, and drilling equipment. A mixed-method approach combining literature review and case study analysis of field applications in offshore platforms was adopted. Findings indicate that duplex and super-duplex stainless steels, along with nickel-chromium-molybdenum alloys, demonstrate exceptional resistance to pitting and crevice corrosion in high-chloride environments. Titanium alloys provide superior strength-to-weight ratio and long-term resistance but remain cost-intensive. The study highlights the balance between mechanical performance, cost, and service life in material selection. Future directions emphasize hybrid materials, nanostructured coatings, and predictive maintenance frameworks to minimize corrosion-induced failures in offshore oil and gas engineering.
