Maintain a shipping container near salt water by removing deposited salt with fresh water where runoff can be managed, keeping the unit dry and clear of trapped debris, and inspecting coatings, seams, door gear, roof edges, lower rails and the underside more often than at an inland site. Repair coating breaks before corrosion spreads, but have pitting, perforation or structural section loss assessed rather than covered with paint.
