Application and research of sacrificial anode of spud legs and spud cans of jack-up drilling platform
To protect the metal structure of the jack-up drilling platform from being damaged by seawater electrochemical corrosion,the spud legs and spud cans of the platform should be effectively protected during its life cycle by reasonably determining the type and quantity of their sacrificial anode.This paper primarily consists of four parts:the calculation of the replacement time for the sacrificial anode,the determination of the cathodic protection,the selection of the sacrificial anode,and the calculation of its quantity.Protected objects in different positions are calculated separately,with inspection rules for the offshore mobile platform taken into consideration.The study shows that the standard sacrificial anode type and its standard quantity for different protected objects can be determined through computational calculation,in view of the time for docking survey.
