C08 – Structural and Material Response to the Marine Environment
Cover electrochemical corrosion, seawater chemistry, general ship corrosion and localised attack mechanisms, building from corrosion electrochemistry and the Nernst equation to the shipboard and localised damage mechanisms that govern inspection, materials selection and corrosion control.

Course overview
Designed for: engineering graduates looking for refresher courses in niche expert areas.
Entry requirements: an engineering degree or equivalent experience, plus basic chemistry (ions, moles, pH) and a general familiarity with ship structures, tanks and materials.
What you will learn
Explain aqueous corrosion as an electrochemical process and relate corrosion current to metal loss.
Calculate equilibrium electrode potentials with the Nernst equation and interpret mixed-potential behaviour.
Analyse how seawater composition, pH, dissolved gases, scale formation, and biofouling influence corrosion risk.
Diagnose general corrosion conditions in ship structures, ballast tanks, and cargo tanks.
Distinguish major localised corrosion mechanisms in marine systems and explain the conditions that promote them.
Apply corrosion-rate, Nernst, pH and galvanic calculations to assess corrosion risk in marine structures.
